What Is Gross Monthly Income? How to Calculate It (2026)

Gross monthly income is the total amount of money you earn in a month before any taxes, deductions, or withholdings are taken out. It’s the “top line” number — your full earnings before Uncle Sam, your 401(k), health insurance premiums, and everything else reduces it to your take-home pay.

Understanding your gross monthly income matters because lenders, landlords, and government programs all use it to evaluate your financial capacity. Your mortgage approval, apartment application, and student loan repayment plan are all based on gross — not net — income.

How to Calculate Gross Monthly Income

The formula depends on how you’re paid. Here are the most common scenarios:

From Annual Salary

The simplest calculation. Divide your annual salary by 12:

Gross Monthly Income = Annual Salary ÷ 12

Example: A $72,000 salary ÷ 12 = $6,000 gross monthly income

From Hourly Wage

Multiply your hourly rate by the number of hours you work per week, then by 52 weeks, then divide by 12 months:

Gross Monthly Income = Hourly Rate × Hours/Week × 52 ÷ 12

Example: $25/hour × 40 hours × 52 ÷ 12 = $4,333 gross monthly income

If you work variable hours, use your average weekly hours over the past 3–6 months for a more accurate figure. Our salary to hourly converter can help you translate between hourly and annual pay instantly.

From Biweekly Pay

If you’re paid biweekly (every two weeks), you receive 26 paychecks per year — not 24. This is a common mistake that leads to underestimating your gross monthly income:

Gross Monthly Income = Biweekly Gross Pay × 26 ÷ 12

Example: $2,500 biweekly gross × 26 ÷ 12 = $5,417 gross monthly income (not $5,000 as many people assume by simply doubling a biweekly check)

From Semi-Monthly Pay

If you’re paid twice a month (1st and 15th, for example), you receive exactly 24 paychecks per year:

Gross Monthly Income = Semi-Monthly Gross Pay × 2

Example: $2,750 semi-monthly gross × 2 = $5,500 gross monthly income

From Weekly Pay

Gross Monthly Income = Weekly Gross Pay × 52 ÷ 12

Example: $1,200 weekly gross × 52 ÷ 12 = $5,200 gross monthly income

What’s Included in Gross Monthly Income

Gross monthly income includes all earned and unearned income before deductions:

Wages and salary — your base compensation
Overtime pay — hours worked beyond 40/week at 1.5× rate
Bonuses and commissions — performance pay, signing bonuses, annual bonuses (divide annual total by 12)
Tips — reported and unreported (lenders want all income)
Self-employment income — net business income from Schedule C, Schedule K-1, or 1099 work
Rental income — net rental income (gross rent minus expenses)
Investment income — dividends, interest, realized capital gains
Alimony received — if your divorce was finalized before 2019 (post-2018 alimony is not taxable income)
Social Security benefits — the full benefit amount
Pension and retirement distributions — 401(k), IRA, and pension withdrawals
Side gig income — freelance work, gig economy earnings, reselling

What’s NOT Included

These items are not part of gross monthly income:

Tax refunds — a refund is a return of overpaid taxes, not income
Child support received — not considered taxable income (but some lenders may count it separately)
Gifts and inheritances — not income for tax purposes
Loan proceeds — borrowed money is not income
Workers’ compensation — generally not taxable
Employer-paid benefits — health insurance premiums paid by your employer don’t count as part of your gross salary for most purposes

Gross vs. Net Monthly Income

	Gross Monthly Income	Net Monthly Income
Definition	Total earnings before deductions	What hits your bank account
Includes	All pre-tax compensation	After federal, state, FICA taxes + deductions
Used by	Lenders, landlords, government programs	Your actual budget
Typical ratio	100%	65–80% of gross (varies by state and bracket)

Example: On a $75,000 salary in Texas (no state income tax):

Gross monthly: $6,250
Net monthly: ~$4,950 (after federal tax, Social Security, Medicare)
Ratio: 79%

The same salary in California:

Gross monthly: $6,250
Net monthly: ~$4,450 (after federal + 9.3% state tax + FICA)
Ratio: 71%

Why Lenders Ask for Gross Monthly Income

Lenders use your gross monthly income to calculate your debt-to-income (DTI) ratio, which is a key factor in mortgage approval, auto loans, and credit card applications:

DTI Ratio = Total Monthly Debt Payments ÷ Gross Monthly Income

Example: You earn $6,000/month gross and have $1,800 in monthly debt payments (mortgage, car loan, student loans, minimum credit card payments). Your DTI is $1,800 ÷ $6,000 = 30%.

Most mortgage lenders require:

Front-end DTI (housing costs only): below 28%
Back-end DTI (all debts): below 36–43% for conventional loans, up to 50% for FHA loans

This is why lenders use gross — it’s a standardized, pre-tax measure that’s consistent regardless of your deductions, withholding elections, or state tax rate. Use our mortgage calculator to see how your gross monthly income affects the home payment you can afford.

Apartment Applications

Landlords typically require that your gross monthly income is at least 3× the monthly rent. For a $1,800/month apartment, you’d need to show $5,400+ in gross monthly income. Some high-cost-of-living cities use a 40× annual rule: annual gross income must be at least 40× the monthly rent.

How to Prove Gross Monthly Income

When applying for a mortgage, apartment, or loan, you’ll need documentation:

W-2 employees: Recent pay stubs (usually 2–3 months), W-2 from the previous year, employer verification letter
Self-employed: Two years of federal tax returns (Schedule C or K-1), year-to-date profit and loss statement, 1099 forms
Multiple income sources: Bank statements showing deposits, investment account statements, Social Security award letter, rental lease agreements showing income

Tip: If you have irregular income (commissions, freelance work, seasonal employment), lenders typically average your income over the past 24 months using tax returns. A single good month won’t count as much as a consistent 2-year history.

Frequently Asked Questions

What is gross monthly income?

Gross monthly income is your total monthly earnings before taxes, Social Security, Medicare, health insurance, 401(k) contributions, and any other deductions. It includes all sources of income: salary, hourly wages, overtime, bonuses, commissions, tips, rental income, investment income, and self-employment income. It’s the “before deductions” number — bigger than what you actually receive in your bank account.

How do I calculate gross monthly income from an hourly wage?

Multiply your hourly rate by the number of hours you work per week, multiply by 52 (weeks per year), then divide by 12 (months). Formula: Hourly Rate × Hours/Week × 52 ÷ 12. For example, $20/hour at 40 hours/week: $20 × 40 × 52 ÷ 12 = $3,467 gross monthly income. If you work overtime, add your overtime earnings separately (OT hours × 1.5 × hourly rate × 52 ÷ 12).

Is gross income before or after taxes?

Before taxes. Gross income is always the pre-tax, pre-deduction amount. Net income (take-home pay) is the after-tax amount. When someone asks for your “gross monthly income,” they want the total before any withholdings. When budgeting your personal expenses, use net income — that’s what you actually have available to spend.

What do lenders consider gross income?

Lenders count all documented, recurring income: W-2 wages, salary, self-employment income (averaged over 2 years), rental income (net of expenses), alimony (pre-2019 divorces), Social Security, pensions, disability income, and investment income. They generally do not count one-time windfalls, unemployment benefits, child support, or income that can’t be documented with tax returns or pay stubs.

How do I prove gross monthly income?

The most common proof is recent pay stubs (2–3 months) for W-2 employees, combined with your most recent W-2 or tax return. Self-employed individuals need 2 years of federal tax returns plus a year-to-date profit and loss statement. For non-employment income (rental, investment, Social Security), provide account statements or award letters. Lenders and landlords may also request an employer verification letter or bank statements showing consistent deposits.
