Whether monthly income is gross or net depends entirely on who’s asking. Mortgage lenders, credit card issuers, and most landlords want your gross monthly income — your pay before any taxes or deductions come out. Courts calculating child support, your own household budget, and federal wage garnishment protections work from your net monthly income — what actually reaches your bank account. Put the wrong number on the wrong form and you can lose credit, miss out on an apartment, or in some cases face a fraud investigation.
A Quick Rule of Thumb
If the form is about deciding whether to lend you money or rent you something, assume gross. If the form is about how much money you actually have to live on, assume net. When the application doesn’t say, read the fine print or ask — the two numbers can differ by 25% or more once taxes, insurance, and retirement contributions come out, and that gap is enough to change an approval decision or a court-ordered payment.
What Gross Monthly Income Is
Gross monthly income is everything you earn in a month before any taxes or deductions are subtracted. Under federal tax law, gross income covers compensation from all sources: wages, salaries, bonuses, commissions, tips, interest, dividends, rental income, and retirement distributions.1GovInfo. 26 U.S.C. 61 – Gross Income Defined For most employees, the practical pieces are base salary or hourly wages plus any overtime, bonuses, commissions, and reported tips.
Your employer reports total gross compensation to the IRS on Form W-2 at year-end. Independent contract work gets reported on Form 1099-NEC. On a pay stub, gross pay is always the larger number: it’s the starting point from which everything else is subtracted.
What Net Monthly Income Is
Net monthly income, also called take-home pay, is what’s left after every deduction. This is the cash that hits your checking account on payday.
The mandatory deductions are federal income tax withholding and FICA. FICA has two pieces: a 6.2% Social Security tax on earnings up to $184,500 in 2026, and a 1.45% Medicare tax on all earnings with no cap.2Social Security Administration. Contribution and Benefit Base Together those run 7.65% of most paychecks.3Internal Revenue Service. Topic No. 756, Employment Taxes for Household Employees State and local income taxes, where they apply, come out on top of that.
Voluntary deductions reduce net pay further. Pre-tax items — health insurance premiums, traditional 401(k) contributions (up to $24,500 in 2026, or $32,500 if you’re 50 or older), and HSA contributions (up to $4,400 for self-only or $8,750 for family coverage in 2026) — come out before income taxes are calculated.4Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Post-tax items like Roth 401(k) contributions, union dues, and some disability premiums come out after taxes. Court-ordered garnishments reduce net pay too.
Where AGI Fits In
Some applications ask for neither gross nor net. They ask for adjusted gross income (AGI). AGI starts with your total gross income and subtracts specific items listed on Schedule 1 of your federal return: deductible IRA contributions, student loan interest, self-employment tax, HSA contributions, and educator expenses, among others.5Internal Revenue Service. Definition of Adjusted Gross Income AGI sits between gross and net: lower than gross because of those adjustments, higher than net because it doesn’t account for payroll taxes or paycheck-level deductions.
AGI drives federal income-driven student loan repayment, where your monthly payment is based on the gap between your AGI and a percentage of the federal poverty guideline for your family size.6Federal Student Aid. Questions and Answers About IDR Plans It also controls eligibility for a long list of tax credits and deductions. When a form says “income,” confirm whether it means gross, net, or AGI before you fill it in. The AGI number lives on line 11 of your most recent Form 1040.
Turning a Paycheck Into a Monthly Number
Your pay stub shows both gross and net in separate columns. Converting either to a monthly figure depends on your pay schedule. Most months contain more than four full weeks, so multiplying a weekly check by four will undercount you.
- Weekly pay: multiply one check by 52, then divide by 12.
- Biweekly pay (every two weeks): multiply one check by 26, then divide by 12. Some years, including 2026, produce 27 biweekly pay dates on the calendar instead of 26, which can shift the per-check amount if your employer spreads your salary across 27 checks.
- Semimonthly pay (twice a month on set dates): add the two checks together.
- Annual salary: divide the yearly figure by 12.
Use the gross line for a gross monthly number, the net line for a net monthly number. Most lenders accept two recent pay stubs or a year-to-date summary as documentation.
When Gross Is the Right Number
Gross income is the standard for credit decisions because it gives lenders a consistent way to compare borrowers who may have very different tax situations and benefit elections.
Mortgage Lending
Mortgage lenders look at your debt-to-income ratio: total monthly debt payments divided by gross monthly income. The current General Qualified Mortgage rule drops the old hard 43% DTI ceiling and uses a price-based test instead, where the loan’s annual percentage rate can’t exceed the average prime offer rate for a comparable loan by more than 2.25 percentage points for most first-lien mortgages.7Federal Register. Qualified Mortgage Definition Under the Truth in Lending Act (Regulation Z): General QM Loan Definition Lenders still have to consider DTI or residual income and verify both. In practice many treat 43% to 50% DTI as an internal guideline, so your gross number remains central.
Credit Cards
Federal regulation requires every card issuer to evaluate your ability to make at least the minimum payment before opening an account or raising your limit. The issuer must consider your current or reasonably expected income — salary, wages, bonuses, tips, commissions, and investment income — along with your existing obligations.8eCFR. 12 CFR 1026.51 – Ability to Pay Most card applications ask for gross annual income.
Rental Applications
Landlords commonly require that gross monthly income equal at least three times the monthly rent, sometimes framed as rent at or below 30% of gross earnings. A guarantor or co-signer, if you need one, usually has to show gross income of four to five times rent. The multiplier varies by property, so check the listing before applying.
Self-Employed Borrowers
If you work for yourself, there’s no pay stub with tidy columns. Lenders generally treat your gross monthly income as your average monthly revenue before business expenses, and your net as the profit after. Most applications want an annual figure from your most recent tax return divided by 12. If you’ve been self-employed less than a year, expect to supply bank statements or a profit-and-loss statement for the months you’ve been operating.
When Net Is the Right Number
Net income is what matters when the question is how much cash you actually have, not what you earn on paper.
Personal Budgeting
Build a monthly budget around net income. That’s the money you can spend or save. Budgeting from gross figures leads to overspending because the money being counted was never in your account.
Child Support and Alimony
Family courts in many states calculate child support as a percentage of one or both parents’ net income, on the theory that the paying parent needs to keep enough after the obligation to cover basic living expenses. Formulas vary: some states use net, others use gross with standardized deductions, a few use a hybrid. Check your state’s guidelines for the exact definition before running numbers.
Wage Garnishment
Federal garnishment caps work from disposable earnings, which track closely with net income after legally required deductions. For ordinary consumer debts, the maximum garnishment is the lesser of 25% of disposable earnings or the amount by which weekly disposable earnings exceed $217.50 (30 times the $7.25 federal minimum wage). Child support and alimony garnishments can reach 50% to 65% of disposable earnings, depending on whether you support another family and whether payments are more than 12 weeks overdue.9U.S. Department of Labor. Fact Sheet 30, Wage Garnishment Protections of the Consumer Credit Protection Act If your state sets a lower cap, the more protective limit controls.
Why Picking the Wrong Number Matters
Putting a false income figure on a financial application carries real legal exposure, not just a bounced form.
- On a mortgage application, knowingly making a false statement to influence a federally insured lender is a federal crime punishable by up to $1,000,000 in fines, up to 30 years in prison, or both.10Office of the Law Revision Counsel. 18 U.S.C. 1014 – Loan and Credit Applications Generally
- Inflating income on a credit card application is credit fraud. Even without criminal charges, the issuer can close the account, demand immediate repayment, and report the default to the credit bureaus.
- Falsified income on a rental application is grounds for denial, and if discovered after you sign, may support eviction depending on the lease and local law.
- Overstating or understating income on benefits programs that run on AGI or net income — Medicaid, subsidized housing, income-driven student loan repayment — can trigger repayment demands, loss of benefits, and in some cases fraud charges.
The safe move is to pull the exact figure from the document the application is pointing at. If the form asks for gross, use the gross line on your pay stub or your W-2 Box 1 figure divided by 12. If it asks for net, use your actual take-home. If it asks for AGI, use line 11 of your most recent Form 1040. Match the number to the question and you avoid the whole category of problems.
