What is an auto loan?
An auto loan is a secured installment loan used to finance the purchase of a new or used vehicle. The car itself is the collateral — if you default, the lender can repossess and sell it. Because of that security, auto loans typically carry lower interest rates than unsecured personal loans or credit cards. The average outstanding US auto loan balance crossed $1.66 trillion in 2025, with 100 million Americans carrying car debt.
Auto loans come in three main flavors: (1) direct lending — you get pre-approved by a bank, credit union, or online lender BEFORE shopping; (2) indirect lending — the dealer arranges financing through a network of lenders and earns a commission; (3) captive financing — the manufacturer's own bank (Toyota Financial, Ford Credit, GM Financial) which often offers promotional rates like 0% APR to move specific models. Each has trade-offs covered later on this page.
The structure is simple: you borrow a principal (price + tax + fees − down payment − trade-in), pay it back monthly over a fixed term (36 to 84 months) at a fixed APR. Each payment covers interest accrued plus a chunk of principal. Early payments are mostly interest; later ones are mostly principal. The loan is fully paid off (amortized) at the end of the term.
How auto loans work
An auto loan is a fixed-rate, fixed-term installment loan secured by the vehicle. Your monthly payment depends on three things: the loan amount (price + sales tax + fees − down payment − trade-in), the APR (annual interest rate), and the term (months). The standard amortization formula produces a level payment each month, with early payments mostly interest and later payments mostly principal.
Payment = P × [r(1+r)n] / [(1+r)n − 1]
P = loan amount, r = monthly rate (APR÷12), n = total months
Most states tax the price after deducting trade-in value (a meaningful savings — on a $30K car with a $10K trade-in at 6% tax, you save $600). Total cost of ownership = down payment + trade-in equity + sum of all monthly payments. Compare that against the lease total cost in the calculator's "Lease vs Buy" mode.
Auto loan calculation walkthrough
Let's calculate a real example: $35,000 SUV, $5,000 down, $7,000 trade-in, 60-month loan at 7.5% APR, 6.25% sales tax, $500 dealer fees.
Step 1 — Sales tax base: $35,000 − $7,000 trade-in = $28,000 taxable
Step 2 — Sales tax: $28,000 × 6.25% = $1,750
Step 3 — Loan amount: $35,000 + $1,750 + $500 fees − $5,000 down − $7,000 trade-in = $25,250
Step 4 — Monthly rate: 7.5% ÷ 12 = 0.625% (or 0.00625)
Step 5 — Monthly payment: $25,250 × [0.00625 × (1.00625)60] / [(1.00625)60 − 1] = $506.18/mo
Step 6 — Total paid over 60 months: $506.18 × 60 = $30,371
Step 7 — Total interest: $30,371 − $25,250 = $5,121 in interest
Use the calculator above to instantly model different scenarios. The amortization table shows how each year's principal vs interest splits — early in the loan, ~30% of each payment goes to interest; by year 5, that drops to ~5%. This is why making extra principal payments early in the loan saves the most.
2026 average APRs by credit tier
Average rates from Experian's State of the Automotive Finance Market Q4 2025. Used-car rates are higher than new because used cars depreciate faster and the lender's collateral is worth less.
| Credit Tier | FICO Range | New Car APR | Used Car APR |
|---|---|---|---|
| Super Prime | 781–850 | 5.49% | 7.21% |
| Prime | 661–780 | 6.94% | 9.42% |
| Near Prime | 601–660 | 9.62% | 14.21% |
| Subprime | 501–600 | 13.45% | 19.07% |
| Deep Subprime | 300–500 | 15.81% | 21.55% |
A 100-point credit-score improvement before financing can save thousands. Pay down credit cards (utilization <30%), avoid new credit applications for 6 months, and check your report for errors.
Pre-approval: your #1 negotiation tool
Before walking into any dealership, get pre-approved by at least one outside lender. This single step routinely saves buyers $1,500–$4,000 over a typical loan. Why? Dealers profit from financing in two ways: (1) by marking up the lender's quoted "buy rate" by 1–3% (you pay more, dealer pockets the difference, called dealer reserve), and (2) by selling add-ons (extended warranty, paint protection, gap insurance) bundled into your monthly payment. Pre-approval defeats both tactics.
Where to get pre-approved:
- Credit unions — typically the best rates (often 0.5–1.5% below banks). PenFed, Navy Federal, DCU, Alliant Credit Union accept anyone nationally.
- National banks — Capital One Auto Navigator, Bank of America, Chase Auto. Easy online process.
- Online lenders — LightStream (no fees, no liens), Carvana Financing, MyAutoLoan (multiple lender quotes), AutoPay.
- Local community banks — relationship matters; existing checking customers get better rates.
Apply with 2–4 lenders within a 14-day window. FICO and VantageScore both treat multiple auto-loan inquiries within 14 days as a single hard pull, so your credit score isn't damaged. Bring the best offer to the dealer and say "beat this rate or I'll use my pre-approval." Most dealers will try.
Bank vs credit union vs dealer financing
| Lender Type | Typical APR vs Average | Pros | Cons |
|---|---|---|---|
| Credit union | −1.0 to −1.5% | Best rates; member-owned; flexible underwriting | Must join; smaller branch network |
| National bank | −0.3 to +0.5% | Easy online; existing relationship discount | Stricter credit minimums (660+) |
| Online lender | Varies widely | Fast; soft-pull pre-quals; 24/7 | Some fees; quality varies |
| Captive (manufacturer) | Promo: 0–3%; standard: +0.5 to +2% | Best promo rates on slow-moving models | Promo requires top-tier credit; rebate often better than 0% |
| Dealer / indirect | +1 to +3% (markup) | Convenient; one-stop | Highest rates; opaque markups |
Order to apply: (1) Your credit union, (2) one or two national banks/online lenders, (3) Then ask the dealer to beat the best offer. Don't accept dealer financing without comparing. If a manufacturer is offering 0% APR, run the numbers — sometimes a $2,000–$3,000 rebate plus a 4% loan is cheaper than 0% financing without rebate.
How much should you put down?
The traditional rule: 20% on a new car, 10% on a used car. The reasoning: new cars depreciate ~20% in year one, so a 20% down payment keeps you from being underwater immediately. Used cars depreciate slower, so 10% works.
Down payment effects on a $30,000, 60-month, 7% APR loan:
| Down payment | Loan amount | Monthly | Total interest |
|---|---|---|---|
| $0 (0%) | $30,000 | $594 | $5,651 |
| $3,000 (10%) | $27,000 | $534 | $5,086 |
| $6,000 (20%) | $24,000 | $475 | $4,520 |
| $9,000 (30%) | $21,000 | $416 | $3,955 |
Going from 0% to 20% down saves $1,131 in interest and reduces underwater risk. But don't drain your emergency fund — keep at least 3 months of expenses liquid. If choosing between a bigger down payment OR keeping cash for a 401(k) match, the 401(k) match wins (instant 50–100% return).
Lease vs Buy: how to decide
| Factor | Buy | Lease |
|---|---|---|
| Monthly payment | Higher (financing whole car) | Lower (financing depreciation only) |
| Mileage | Unlimited | 10K–15K/yr cap; $0.15–0.30/mi over |
| End of term | Own the car (no payments) | Return car or buy at residual |
| Customization | Anything you want | No modifications allowed |
| Wear & tear | Your problem (and asset) | Charged at lease return |
| Best for | High mileage, long-term ownership | Low mileage, want a new car every 3 years |
| EV federal credit | Expired Sept 30, 2025 (OBBB) | Expired Sept 30, 2025 (OBBB) |
How lease payments are calculated
A lease payment has two main components: depreciation (the car's value loss during your lease) and rent charge (interest on both the financed depreciation AND the residual that the lessor still owns).
Lease formula:
Depreciation = (Adjusted Cap Cost − Residual) ÷ Lease Term
Rent Charge = (Cap Cost + Residual) × Money Factor
Monthly Payment = Depreciation + Rent Charge + Sales Tax
Money Factor → APR: multiply by 2,400. So MF 0.00250 = 6.0% APR. Always negotiate the cap cost (just like a buy price) and ask for the lender's 'buy rate' money factor — dealers can mark this up by up to 0.0004 (≈1% APR) and pocket the difference.
Lease worked example
Let's lease the same $35,000 SUV for 36 months: 58% residual, MF 0.00208 (= 5.0% APR), $700 acquisition fee, $3,000 down, 6.25% sales tax.
Adjusted Cap Cost: $35,000 + $700 acquisition − $3,000 down = $32,700
Residual Value: $35,000 × 58% = $20,300
Depreciation/month: ($32,700 − $20,300) ÷ 36 = $344.44
Rent Charge/month: ($32,700 + $20,300) × 0.00208 = $110.24
Base Payment: $344.44 + $110.24 = $454.68
Sales Tax: $454.68 × 6.25% = $28.42
Monthly Payment: $483.10/mo
Total over 36 months: ($483.10 × 36) + $3,000 down + $400 disposition = $20,792
Compare to buying same SUV (60-month, 7.5% APR, $5K down): $506/mo, but you OWN the car worth ~$22K at month 36. Lease costs $20,792 with no asset; buy costs ~$23,300 in payments through month 36 plus you have a $22K car. Buy comes out ahead by ~$18,500 in equity, but you have 24 more months of payments and a depreciating asset. The decision hinges on what you do at month 36 — keep driving (buy wins) or get a new car (lease often wins).
Hidden lease fees to watch for
- Acquisition fee ($395–$1,095): Charged at lease start to "originate" the lease. Almost always rolled into cap cost (so you pay interest on it via rent charge). Non-negotiable but varies by brand: BMW $925, Honda $595, Toyota $650.
- Disposition fee ($300–$500): Due at lease end if you return the car (don't buy or re-lease from the same brand). Often waived if you lease another car from same brand.
- Excess mileage ($0.15–$0.30/mi): Standard allowance is 10K, 12K, or 15K miles per year. Drive 20K with a 12K cap on a 36-month lease? You owe (60K − 36K) × $0.20 = $4,800 at lease end.
- Wear-and-tear: Beyond "normal" wear. Door dings >2", scratched wheels, stained interior, missing keys ($300+). Get a third-party inspection 60 days before turn-in to fix issues cheaper.
- Early termination penalty: Usually all remaining payments. Avoid via "lease swap" sites like SwapaLease or LeaseTrader — find someone to take over your lease.
- Gap insurance (often required, sometimes already included): Confirm before paying separately.
- Doc fees: Same as a buy — $75–$799 depending on state regulation. Florida and California cap dealer doc fees by law.
Get every fee in writing on the lease worksheet (the document showing cap cost, residual, MF, fees) BEFORE signing. Ask: "What are all fees due at signing, monthly, and at lease end?" Anything not on paper isn't enforceable.
Why 84-month loans are a trap
7-year (84-month) loans look attractive because of lower monthly payments, but the math is brutal. Compare a $35,000 loan at 7% APR:
| Term | Monthly | Total Interest | Total Paid |
|---|---|---|---|
| 48 months | $838 | $5,225 | $40,225 |
| 60 months | $693 | $6,610 | $41,610 |
| 72 months | $597 | $7,985 | $42,985 |
| 84 months | $528 | $9,400 | $44,400 |
The 84-month payment saves $310/month vs 48-month — but costs $4,175 more in total interest. Worse: the car depreciates faster than you pay it down, so you're "underwater" (owe more than it's worth) for years. If you wreck it or want to sell, you owe the lender the gap.
Sales tax + dealer fees explained
Sales tax on car purchases varies wildly by state and is the single largest "extra" cost beyond the sticker price. Combined state + local rates range from 0% (Alaska, Delaware, Montana, New Hampshire, Oregon) to over 9% (parts of LA, OK, AL, AR, TN). On a $35K car, that's a $0–$3,150 swing.
Trade-in tax credit: most states (38 + DC) tax only the difference between your purchase price and trade-in value. So buying a $35K car with a $10K trade in a 7% state means tax on $25K = $1,750, not $35K × 7% = $2,450 — a $700 savings. States that DON'T allow trade-in credit: California, Hawaii, Kentucky, Maryland, Michigan (partial), Virginia, and Washington DC.
Standard dealer add-on fees:
- Documentation (doc) fee: $75–$799 depending on state. CA caps at $85, NY/NJ at $75–$175, FL/TX/AL allow $300–$799. Negotiable in some states; mandatory in others.
- Title fee: $15–$50, set by your DMV. Not negotiable.
- Registration: Varies by state, often based on vehicle weight or value. CA: $60+$28+VLF (~1% of value). TX: ~$50–$108. Florida: $225 first-time + $14 annual.
- License plate: $10–$50, included in registration usually.
- "Dealer prep" / "VIN etching" / "nitrogen tires": Pure profit add-ons. Refuse them.

Federal EV tax credits expired Sept 30, 2025
Important update: The One Big Beautiful Bill (OBBB) Act, signed July 2025, terminated all federal EV tax credits — Section 30D (new clean vehicle credit, up to $7,500), Section 25E (used clean vehicle credit, up to $4,000), and Section 45W (commercial clean vehicle credit, the "lease loophole"). All three credits ended for vehicles acquired after September 30, 2025. As of 2026, no federal EV purchase or lease credit applies.
Historically (through Sept 30, 2025), the credits worked as follows — included here for context if you're researching past purchases or filing 2025 returns:
- Section 30D (buyers, 2023–Sept 2025): Up to $7,500 for new EVs meeting North American assembly, battery sourcing, MSRP caps ($80K SUVs/trucks/vans, $55K cars), and buyer income caps ($150K single / $300K MFJ / $225K HoH).
- Section 25E (buyers, 2023–Sept 2025): Up to $4,000 for used EVs ($25K cap, income limits half of new EV thresholds).
- Section 45W (commercial / lease loophole, 2023–Sept 2025): Up to $7,500 for leased EVs with no buyer income limit and no assembly/battery sourcing rules. Leasing companies typically passed this through as a cap cost reduction — the famous "lease loophole" that made imported EVs (Hyundai Ioniq, Kia EV6, Polestar) attractive to lease vs buy.
For 2026 EV buyers: Some state-level EV incentives still exist (California CVRP, Colorado state credit up to $5,000, New York Drive Clean rebate, etc.). Check your state's energy office for current rebates. Many manufacturers (Tesla, GM, Ford, Hyundai) have introduced their own price cuts and financing promotions to partially offset the loss of the federal credit.
If you bought or leased an EV between January 2024 and September 30, 2025, you may still claim the credit on your 2024 or 2025 tax return — consult a tax professional for filing details.
When to refinance an auto loan
Auto refinancing replaces your existing loan with a new one (usually from a different lender) at a different rate or term. Unlike mortgage refis, there's no closing costs and process takes 7–14 days. When it makes sense:
- Credit score improved 50+ points since original loan — most common driver of savings.
- Original loan was dealer-arranged subprime (high APR with markup) — refinancing through a credit union almost always saves $1,000+.
- Market rates have dropped 1%+ since you got the loan.
- You need lower monthly payment for cash flow — extending term lowers payment but increases total interest. Use only as a last resort.
When NOT to refinance: (1) you're already deep in the loan (last 12–18 months) — front-loaded interest means little savings; (2) your loan has prepayment penalties (uncommon but check); (3) your current loan is under 5%; (4) you're underwater and refinancing requires bringing cash to close.
Where to refinance: PenFed, Navy Federal, Alliant, RateGenius, AutoPay, MyAutoLoan, LightStream, Capital One. Get 2–3 quotes within 14 days (single FICO inquiry). Most lenders allow soft-pull pre-quals.
Negative equity / underwater loans
You're "underwater" (or have "negative equity") when your loan balance exceeds the car's market value. New cars depreciate ~20% in year one and ~50% by year five. Combined with low/no down payment and long terms (72/84 months), this creates extended underwater periods.
As of 2025, the average new-car negative equity for trade-ins was $6,755 (per Edmunds), an all-time high. About 22% of trade-ins came in underwater. The risk:
- Total loss / theft: Insurance pays the car's market value, NOT your loan balance. The gap is yours to pay. Gap insurance covers this.
- Trade-in penalty: Negative equity gets rolled into your NEXT loan. So a $40K new car + $7K rolled negative equity = $47K loan on a $40K asset. You're now $13K+ underwater immediately.
- Can't sell easily: Buyer pays market value; you have to bring cash to close to pay off the lender.
How to avoid: (1) Put 20%+ down on new, 10%+ on used; (2) keep loans ≤60 months; (3) buy slightly used (1–2 years old) to skip the worst depreciation; (4) choose models with strong resale value (Toyota, Honda, Subaru, Lexus); (5) buy gap insurance from your auto insurer ($30–60/year) if you have <20% equity.
Total cost of ownership: beyond the payment
The monthly loan payment is only ~50–60% of true car costs. Per AAA's 2025 "Your Driving Costs" report, a new-car owner pays an average of $12,297/year ($1,025/month) all-in across all vehicle classes.
| Cost category | Annual avg | % of total |
|---|---|---|
| Loan payment + finance costs | $5,448 | 44% |
| Depreciation | $4,538 | 37% |
| Insurance | $1,810 | 15% |
| Fuel | $2,148 | 17% |
| Maintenance + repair + tires | $1,403 | 11% |
| License, registration, taxes | $728 | 6% |
Budget the 20/4/10 rule: 20% down, 4-year max term, total transportation costs (loan + insurance + fuel + maintenance + parking) under 10% of gross income. EVs typically cut fuel by 60% and maintenance by 30%, but insurance is 10–20% higher. Use our Gas Mileage Calculator to estimate fuel costs precisely.
10 costly auto financing mistakes
- Shopping by monthly payment, not total cost. Dealers love this — they'll stretch the term to whatever monthly figure you say. Always negotiate the OUT-THE-DOOR PRICE, then financing.
- Skipping pre-approval. Walking in without an outside loan offer guarantees you pay the dealer markup. Costs $1,000–$4,000 in extra interest.
- Taking 84-month loans. Lower payment, but you're underwater for 4–5 years and pay 80% more interest than a 48-month loan.
- Buying extended warranty from F&I office. Markup is huge ($1,500–$3,000 over wholesale). Buy from your manufacturer's website or third-party (Endurance, CarShield) at half the price — or skip entirely (most warranties don't pay out enough).
- Rolling negative equity into the new loan. Pay off the gap in cash if possible; otherwise wait until you have positive equity before trading.
- Buying gap insurance from the dealer. $600–$900 once vs $30–60/year through your auto insurer. Save $400+.
- Not negotiating the lease cap cost. ~30% of lessees pay full MSRP, not realizing the cap cost is negotiable just like a buy price.
- Choosing 0% APR over the rebate without doing the math. Sometimes a $3,000 rebate + 4% loan is cheaper than 0% with no rebate.
- Putting too little down. $0 down on a 72-month loan = 3+ years underwater = high gap insurance bills + can't trade out.
- Forgetting insurance increases. A new car often doubles your insurance premium. Get a quote BEFORE buying — sticker shock can change your purchase decision.
8 strategies to save thousands
- Buy a 1–2 year-old used car. Saves 20–35% off new while modern cars easily last 200K+ miles. Certified Pre-Owned (CPO) gives you manufacturer warranty extension.
- Get pre-approved at a credit union FIRST. Floor your APR before stepping foot in a dealer. Credit unions average 1–1.5% below national bank rates.
- Time the purchase end-of-month or end-of-quarter. Salespeople have quotas; they cut deals to hit them. End of December is best — combined annual + quarterly + monthly + model-year-clearance pressure.
- Negotiate the OUT-THE-DOOR price. Total cash to drive away (price + tax + fees). Don't talk monthly payment.
- Sell privately instead of trading in. Dealer trade-in offers are typically 15–25% below retail. Selling to CarMax, Carvana, or private buyer recovers thousands. (Trade-in tax credit can offset some of this in 38 states.)
- Skip dealer add-ons. "Paint protection" (markup 500%), "rust proofing" (your car has factory protection already), "VIN etching" ($30 cost, $300 charge), "nitrogen tires" (regular air is 78% nitrogen). Refuse them all.
- Lease an EV instead of buying. No longer benefits from the federal "lease loophole" (Section 45W expired Sept 30, 2025), but still hedges against fast-changing battery tech and unstable EV resale values. Check for state-level EV rebates.
- Make biweekly payments. Pay half your monthly amount every 2 weeks instead of one full payment per month. Result: 26 half-payments = 13 full payments per year (one extra), shaving 4–6 months off a 60-month loan and saving ~$500 in interest.

Frequently asked questions
How does the auto loan calculator work?
Enter the vehicle price, down payment, trade-in value, your state's sales tax rate, loan term (commonly 36/48/60/72/84 months), and the APR you've been quoted. The calculator computes your monthly payment using the standard amortization formula, plus the loan amount after tax and fees, total interest paid over the loan, and a year-by-year breakdown of how each payment splits between principal and interest.
What's a good auto loan APR in 2026?
Average rates by credit tier (per Experian Q4 2025): Super Prime (781+) gets ~5.49% new / 7.21% used. Prime (661–780) gets ~6.94% new / 9.42% used. Near Prime (601–660) jumps to 9.62%/14.21%. Subprime (501–600) hits 13.45%/19.07%. Deep Subprime (300–500) is 15.81%/21.55%. Improve your credit before financing — even a 50-point bump can save thousands.
Should I buy or lease a new car?
Buy if: you drive a lot (15K+ miles/year), keep cars 5+ years, want to avoid lease wear-and-tear charges, and value owning the asset. Lease if: you want lower monthly payments, prefer a new car every 2–3 years, drive under 12K miles/year, can deduct lease payments through a business, and don't want repair surprises post-warranty. Long-term (10+ years), buying almost always wins financially. Short-term (3 years) leasing can win if you'd otherwise sell early.
How does the lease calculation work?
A lease has two components: depreciation (the car's value loss during your lease) and rent charge (essentially interest on both your portion and the leasing company's portion). Depreciation = (Adjusted Cap Cost - Residual Value) / Lease Months. Rent Charge = (Cap Cost + Residual) × Money Factor. The Money Factor is the lease equivalent of APR: MF × 2400 = APR. Your monthly payment is the sum, plus sales tax (calculated on the monthly payment in most states).
What is residual value?
Residual is what the leasing company estimates the car will be worth at lease end, expressed as a percentage of MSRP. Higher residual = lower depreciation = lower monthly payment. Typical 36-month residuals: Toyota/Honda/Subaru 55–62%, BMW/Mercedes 50–58%, EVs 40–55%, luxury sedans 45–55%. Set by the lender, not negotiable. Cars with high residuals are cheaper to lease relative to their price.
What is money factor?
Money factor (MF) is the lease's interest rate, expressed as a tiny decimal. To convert to APR, multiply by 2400: e.g., MF 0.00250 = 6.0% APR. Lower is better. Tier 1 credit gets the manufacturer's 'buy rate' (lowest); dealers can mark it up by 0.0001–0.0004 (which becomes their profit). Always ask for the buy rate and the marked-up rate.
How much should I put down on a car?
On a buy: 10–20% of price is typical. Larger down = lower monthly + less interest, but never put down more than you can afford to lose to depreciation. Total loan-to-value ideally <100% (so you're never 'underwater'). On a lease: aim for $0 down ('sign and drive'). Down payments on leases reduce monthly payment but you forfeit the cash if the car is totaled — you don't own equity in a lease. Use the same money to lower your buyout if you intend to purchase.
Should I take a 72 or 84-month auto loan?
Tempting because of lower monthly payment, but bad math. A $35,000 loan at 7%: 60-month = $693/mo, $6,610 interest. 72-month = $597/mo, $7,985 interest. 84-month = $528/mo, $9,400 interest. The 84-month payment is $165 less but you pay $2,790 more in interest AND you'll owe more than the car is worth for most of the loan. Stick with 60 months max for new cars, 48 for used.
What about gap insurance?
Gap insurance covers the difference between what you owe and what the car is worth if it's totaled or stolen. Required by most lessors (often built into the lease). For buys, only worth it if your down payment is small (<20%) AND you have a long loan term — the period when you owe more than the car's value can stretch 2–3 years. Buy from your insurance company ($30–60/year) instead of the dealer ($600–900 once).
Can I negotiate the price on a lease?
Yes — and you should. The 'capitalized cost' on a lease IS negotiable, just like the price on a buy. Many shoppers don't realize this and pay full MSRP for a lease. Ask for the cap cost, then negotiate it down with the same tactics you'd use for a purchase. The residual percentage and money factor are set by the manufacturer and not negotiable, but the cap cost is.
What are the hidden lease fees?
Watch for: (1) Acquisition fee — $400–$1,000 to start the lease, often rolled into cap cost. (2) Disposition fee — $300–$500 due at lease end if you don't buy or lease another from same brand. (3) Excess mileage — $0.15–$0.30 per mile over your allowance (usually 10K, 12K, or 15K/yr). (4) Wear-and-tear charges — anything beyond 'normal' (door dings, scratched wheels, stained interior). (5) Early termination — usually equals all remaining payments. Get every fee in writing before signing.
How do EV tax credits affect lease vs buy in 2026?
Federal EV tax credits no longer apply. The OBBB Act (July 2025) terminated all three EV credit programs — Section 30D (new EV buyer credit, up to $7,500), Section 25E (used EV credit, up to $4,000), and Section 45W (the commercial/lease loophole). All three ended for vehicles acquired after September 30, 2025. As of 2026, federal EV incentives are gone. Some state-level rebates remain (CA, CO, NY, NJ, MA) — check your state's energy office. EV manufacturers have introduced their own price cuts to partially offset the credit loss.
What's the difference between APR and interest rate on a car loan?
Interest rate is the cost of borrowing the principal. APR (Annual Percentage Rate) includes the interest rate PLUS lender fees (origination, application, etc.) annualized over the loan term. APR is always equal to or higher than the interest rate, and APR is what the Truth in Lending Act requires lenders to disclose. Always compare loans by APR, not interest rate. On most auto loans the gap is small (0.1–0.3 percentage points) because origination fees are usually low.
Should I get pre-approved for an auto loan before going to the dealer?
Yes — always. A pre-approval from your bank, credit union, or online lender (Capital One, LightStream, Bank of America) gives you: (1) a true APR for negotiation leverage, (2) protection from dealer markup (dealers can add 1–3% to your rate as their profit), (3) clarity on your real budget. Bring the pre-approval to the dealer and let them try to beat it. Auto loan rate shopping within a 14-day window counts as a single credit inquiry for FICO.
Is it better to finance through the dealer or my own bank?
Compare both. Dealer financing (especially manufacturer captive lenders like Toyota Financial, Ford Credit) can offer promotional 0% APR or rebates that a bank can't match. But standard dealer financing is usually marked up. Get a bank/credit union pre-approval first as your floor, then ask the dealer to beat it. If they offer 0% APR vs $2,000 rebate, calculate which saves more — sometimes the cash rebate plus a 4% loan beats the 0% APR.
What credit score do I need to get a car loan?
Technically you can get a loan with any score (subprime lenders accept 500+), but the APR difference is huge. 750+ qualifies for the best 'super prime' rates (5–6% in 2026). 660–750 gets prime rates (7–9%). 600–660 gets near-prime (10–14%). Below 600 can mean 18–22% APR. On a $30K loan over 60 months: a 6% APR costs $4,800 in interest; an 18% APR costs $15,800 — a $11,000 difference. Boost your score before financing whenever possible.
What is dealer markup or 'reserve'?
When dealers arrange financing through third-party lenders, the lender quotes a 'buy rate' (the actual rate based on your credit). The dealer can mark this up 1–3 percentage points and pocket the difference as profit (called 'dealer reserve' or 'rate participation'). The CFPB has cracked down on this but it still happens. Counter by getting outside pre-approval and asking the F&I manager to show you the actual buy rate.
Can I refinance my car loan?
Yes. Auto loan refinancing makes sense when: (1) your credit score has improved 50+ points since the original loan, (2) market rates have dropped 1%+, (3) you originally took a subprime loan and now qualify for prime, or (4) you want to extend the term to lower monthly payment (rarely smart financially but can solve cash flow). No prepayment penalty in most cases. Apply with credit unions and online lenders (RateGenius, MyAutoLoan); takes 7–14 days.
Should I make extra payments on my car loan?
Mathematically yes if your APR is higher than what you'd earn investing (typically anything above 5–6%). Even one extra $100 payment per year on a $30K, 60-month, 7% loan saves ~$220 in interest and shaves a month off the loan. Make sure to specify 'apply to principal' — otherwise lenders may apply it to next month's payment, which doesn't reduce interest. Avoid prepayment penalties (rare in auto, but check your contract).
What is being 'underwater' or having negative equity?
It means you owe more on the loan than the car is currently worth. New cars depreciate ~20% the first year, so a $30K car bought with $0 down on a 72-month loan might be worth $24K while you still owe $27K — you're $3,000 underwater. This is dangerous if the car is totaled (insurance pays only the car's value, not your loan), or if you want to trade in. Avoid by putting 15–20% down, keeping loans ≤60 months, and choosing models with high resale value.
Should I include sales tax in my financed loan amount?
Most states allow you to roll sales tax (and title/registration fees) into the loan, which avoids out-of-pocket payment but means you pay interest on the tax. Mathematically, paying tax in cash saves a few hundred in interest. If you can afford to pay tax + fees + 10–20% down upfront in cash, do it. If not, rolling them in is acceptable — just don't extend the term to compensate.
What's the best loan term — 36, 48, 60, 72, or 84 months?
Best for most buyers: 48–60 months. 36-month: lowest interest, highest payment — only if budget allows. 48 months: good balance for most. 60 months: standard, but watch interest costs. 72 and 84 months: 'affordability traps' — lower payment but huge total interest and prolonged underwater period. Used cars: stick to 48 max. New cars under $30K: aim for 60 max. EVs (which depreciate faster): keep terms short to avoid underwater.
What is the rule of 78s and does it apply to auto loans?
The Rule of 78s is an old front-loaded interest method that allocates more interest to early months, penalizing early payoff. The Federal Truth in Lending Act banned it for loans 61+ months in 1992, and most states have banned it entirely. Modern auto loans use 'simple interest' — interest accrues daily on the outstanding balance. Verify your loan is simple interest before signing; ask if there's a prepayment penalty.
Should I lease an EV in 2026?
Two reasons leasing still makes sense for many EV shoppers (note: the federal $7,500 credit and lease loophole expired Sept 30, 2025 under OBBB, so that benefit no longer applies). (1) EV technology is improving fast (battery capacity, charging speed) — leasing avoids being stuck with outdated tech in 5 years. (2) EV residuals are uncertain — some have plummeted due to Tesla price cuts and supply growth, so leases let the lessor absorb depreciation risk. Run the comparison in our calculator's 'Lease vs Buy' mode and check for state-level EV incentives in your area.
How much should I budget for total car costs (not just payment)?
The 20/4/10 rule: 20% down, 4-year max loan, total monthly transportation under 10% of gross income (some say 15% for car payment + insurance + gas + maintenance combined). For a $75K household: keep total car costs under $625–$940/month. Don't forget: insurance ($150–$300/mo), gas ($120–$300), maintenance ($75–$125 averaged), parking, registration. A '$400/month payment' often becomes $850 all-in.
