Which SBA loan program fits your situation
SBA 7(a), the workhorse: Up to $5 million, used for working capital, equipment, real estate, buying out a partner, or acquiring another business. Longest available: 25 years for real estate; 10 years for everything else, working capital included, unless it buys equipment with a useful life over 10 years. The most common SBA loan and the most flexible.
SBA 504, real estate and major equipment only: Three-part structure: usually 50% from a private lender, 40% from an SBA-approved CDC (Certified Development Company) and 10% from the borrower, who puts in 15% if the business is two years old or less or the building is special-purpose, and 20% if both. The CDC portion has a fixed rate set from 10-year Treasury rates. The CDC loan is capped at $5 million ($5.5 million per project for small manufacturers and some energy projects), so the whole project can be two to three times that. Best when buying commercial real estate or expensive equipment for your own use.
SBA Microloan, small businesses, up to $50,000: Administered through nonprofit intermediaries, often with technical assistance bundled in. Higher rates (8-13%) but accessible to startups, women-owned, and minority-owned businesses that might not qualify for 7(a). Average loan size around $13,000.
Qualification reality check
SBA lenders look at five factors, often called the "5 C's of credit": Character (your personal credit history, criminal record, business reputation), Capacity (your business's cash flow and ability to service the debt), Capital (your equity invested in the business), Collateral (assets the bank can claim if you default), and Conditions (industry trends, business climate). All five must pass scrutiny.
Minimum DSCR (Debt Service Coverage Ratio) of 1.15-1.25 is required by most lenders. This means your business's net operating income must exceed annual debt service by 15-25%. A loan with $60,000 annual debt service needs $69,000-$75,000 NOI to pass underwriting. The two-year historical financials must demonstrate this; projections alone aren't sufficient unless the loan funds something that will dramatically improve cash flow.
Personal guarantee is mandatory from anyone owning 20%+ of the business. This means your personal assets are on the hook if the business defaults. SBA loans cannot be "non-recourse." This is the price for the SBA guarantee that lets banks offer better terms.
2026 SBA fee structure
SBA's upfront guaranty fee for 7(a) loans of more than 12 months approved in fiscal year 2026 (Oct 1, 2025 - Sep 30, 2026) is charged on the guaranteed portion (up to 85% of a loan of $150,000 or less, 75% above): 2% for loans of $150,000 or less, 3% for $150,001-$700,000, and 3.5% for $700,001-$5,000,000, with 3.75% on the guaranteed portion over $1,000,000. Manufacturers borrowing $950,000 or less pay 0%. Fiscal year 2027 (from Oct 1, 2026) keeps the same schedule, with 0% for loans of $700,000 or less to manufacturers, food-supply businesses and rural businesses. The lender also pays SBA 0.55% a year on the guaranteed balance, and may not pass it on to you. For 504 loans the upfront fee is 0.5%.
Beyond the SBA's fees, 7(a) lenders may charge only what SBA allows, with no origination fee: packaging fees ($1,500-3,000), closing costs ($2,000-5,000), title insurance for real estate-backed loans (~0.5% of loan), appraisal fees ($500-3,500 depending on collateral), and legal review ($1,500-5,000). Total non-SBA fees typically add up to 1-2% of the loan amount.
SBA charges a prepayment fee (the subsidy recoupment fee) on 7(a) loans of 15 years or more when you prepay more than 25% of the balance in any of the first three years: 5% of the prepayment in year 1, 3% in year 2, 1% in year 3, nothing after. Prepaying 25% or less in a year costs nothing. This matters if you plan to refinance into a private loan once your business establishes credit history: a full refinance is free from year 4.
Speeding up the SBA process
- Use an SBA Preferred Lender (PLP): Banks designated as PLP can approve loans without sending to SBA for review, cutting weeks off the timeline. Wells Fargo, Live Oak Bank, Newtek, Huntington, and Celtic Bank are large PLP lenders.
- Prepare documents before applying: 3 years of personal and business tax returns, year-to-date P&L and balance sheet, debt schedule, business plan (especially for new businesses), personal financial statement, business and personal credit reports, articles of incorporation, lease or purchase agreement for the use of funds.
- Consider SBA Express for under $500K: 36-hour SBA decision, lower paperwork burden, slightly higher rate. Good for working capital and equipment needs that don't require the full 7(a) underwriting.
- Use a broker selectively: A good SBA broker knows which lenders favor which industries. They charge 1-2% of loan amount. Worth it if you've been declined or have a complex situation; not worth it for straightforward applicants.
- Build the relationship before you need the loan: Open business checking at a likely SBA lender 6-12 months before applying. Established relationships speed approvals significantly.
FAQs
What is an SBA loan?
SBA loans are small business loans GUARANTEED (but not directly funded) by the US Small Business Administration. The SBA guarantees 50-85% of the loan, reducing risk for banks who then offer better rates and longer terms than typical commercial loans. SBA loans are NOT free government money, you still pay interest and fees.
What's the difference between SBA 7(a) and 504?
SBA 7(a): General-purpose, up to $5M, used for working capital, equipment, real estate, refinancing. SBA 504: Specifically for real estate and major equipment purchases. The CDC loan is up to $5M ($5.5M per project for small manufacturers and some energy projects), usually as 50% bank + 40% CDC + 10% borrower down payment (15-20% for a business two years old or less or a special-purpose building). 7(a) is more flexible; 504 has lower rates for qualifying projects.
What are 2026 SBA loan rates?
SBA caps 7(a) variable rates at the base rate (usually prime) plus 3 percentage points on loans over $350,000, plus 4.5 on $250,001-$350,000, plus 6 on $50,001-$250,000 and plus 6.5 on $50,000 or less. SBA 504: a fixed rate on the CDC portion, set from 10-year Treasury rates. SBA Microloan (up to $50K): 8-13%. All rates are negotiated with the bank within SBA caps.
What credit score do I need for an SBA loan?
Minimum 680 personal credit score for most SBA lenders. 700+ for the best rates. Some Microloan lenders accept 640+. Business credit (Dun & Bradstreet PAYDEX) also evaluated. Personal guarantee required from anyone owning 20%+ of the business.
How long does SBA loan approval take?
Typical timeline: 60-90 days from application to funding. SBA Express loans (up to $500K): 36 hours decision, faster funding. SBA 504: 90-120 days due to multiple parties. Microloan: 30-60 days. Have all documents ready (3 years tax returns, business plan, financials) to speed the process.
What fees do SBA loans have?
SBA's upfront fee on a 7(a) loan of more than 12 months: 2% of the guaranteed portion up to $150,000, 3% to $700,000 and 3.5% above, with 3.75% on the guaranteed part over $1M (the same for loans approved in FY 2026 and FY 2027). 7(a) lenders can't add an origination fee: only reasonable packaging and service fees, out-of-pocket costs and legal fees. Closing costs: $2,000-$10,000. Total upfront: typically 2-5% of loan amount. SBA caps fees that lenders can charge.
