To calculate gross weekly income, add every source of pre-tax earnings you receive and express the total as a seven-day figure: divide an annual salary by 52, multiply an hourly rate by weekly hours (adding overtime at 1.5 times your regular rate), or divide annual self-employment net profit by 52. Gross means before any taxes, insurance premiums, or retirement contributions come out. Federal tax law defines gross income broadly as all income from whatever source, including wages, business profits, commissions, fringe benefits, interest, rents, and dividends.1Office of the Law Revision Counsel. 26 USC 61 – Gross Income Defined The number matters for mortgage applications, child support calculations, wage garnishment limits, and workers’ compensation claims, so getting each piece right is worth a few minutes with a calculator.
What to Count and What to Leave Out
Gross income is everything you earn before deductions. For a W-2 employee, that means full salary or hourly wages, overtime, tips, bonuses, commissions, and the taxable value of any fringe benefits. For a self-employed person, it means net profit from the business. For someone with multiple streams, it means all of those combined.
What gross income does not include are the amounts pulled from your paycheck on the way to net pay: federal and state income tax withholding, your 6.2% Social Security contribution, your 1.45% Medicare contribution, health insurance premiums, and retirement plan deferrals.2Office of the Law Revision Counsel. 26 USC Chapter 21 – Federal Insurance Contributions Act On a pay stub, look for the “Gross Pay” line. Ignore “Net Pay.”
If You Earn a Salary
Divide your annual gross salary by 52. Someone earning $78,000 per year has a gross weekly income of $1,500.
If you think in paycheck terms rather than annual terms, convert first. Biweekly paychecks arrive 26 times per year, so one biweekly gross amount multiplied by 26 gives you the annual figure. Semi-monthly paychecks arrive 24 times per year, so you multiply by 24. Mixing those two up will throw your number off by roughly 8%. Once you have the annual total, divide by 52.
This method gives you the same weekly figure regardless of your actual pay frequency, because the annual salary is fixed. If your salary changed partway through the year, use your current rate rather than blending old and new, unless a court or lender specifically asks for a 12-month average.
If You Earn an Hourly Wage
For a steady schedule, multiply your hourly rate by weekly hours. At $22 per hour for 40 hours, gross weekly income is $880.
Adding Overtime
Federal law requires most employers to pay at least 1.5 times your regular rate for every hour worked beyond 40 in a single workweek.3Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours That overtime pay is part of gross income. If you worked 48 hours at $22 per hour, the calculation is 40 hours at $22 ($880) plus 8 hours at $33 ($264), for a gross weekly total of $1,144.
Your regular rate for overtime purposes is not always your base hourly wage. Federal regulations define it as total weekly compensation divided by total hours worked.4eCFR. 29 CFR 778.109 – The Regular Rate Is an Hourly Rate Total compensation includes non-discretionary bonuses, commissions, and shift differentials paid for night, weekend, or hazardous work.5eCFR. 29 CFR Part 778 – Overtime Compensation If you earn $22 per hour on day shifts and a 6% differential on nights, the night hours are paid at $23.32, and both rates blend into the regular rate before overtime is applied.
When Your Hours Vary Week to Week
A single pay stub is a bad snapshot when your schedule swings. A common fix is to add gross earnings across the most recent 13 weeks and divide by 13. That captures seasonal patterns, overtime, and slow weeks without letting any one week distort the number. Courts, workers’ compensation systems, and some lenders prefer this averaging approach. Twenty-six or 52 weeks work too if you have the pay stubs.
If You Are Self-Employed
Self-employment shifts the starting point from revenue to net profit. Use Line 31 of Schedule C, which is what remained after deducting business costs like supplies, advertising, vehicle expenses, and the home office.6Internal Revenue Service. 2025 Instructions for Schedule C (Form 1040) Federal tax law defines self-employment income the same way: gross business income minus allowable deductions.7Office of the Law Revision Counsel. 26 USC 1402 – Definitions
Divide annual net profit by 52. A Schedule C showing $62,400 in net profit gives a gross weekly income of $1,200. If you have been in business for less than a full year, divide profit by the weeks you have actually operated. Six months of operation with $28,000 in profit divides by 26 weeks, not 52, for roughly $1,077 per week.
A common freelancer mistake: handing a lender or a court total revenue instead of net profit overstates income; subtracting personal expenses that are not legitimate business deductions understates it. Use what Schedule C actually reports, and keep profit-and-loss records to back up the numbers.
You will want your 1099-NEC forms from each client and your federal return with Schedule C attached.8Internal Revenue Service.

Adding Tips, Bonuses, Commissions, and Fringe Benefits
Base pay is usually just the start.
Tips are taxable income and must be reported to your employer, who includes them in Box 1 of your W-2.10Internal Revenue Service. Tip Recordkeeping and Reporting Annual bonuses and sales commissions count too. Because these do not arrive every week, the cleanest method is to total them over a full 12 months and divide by 52. If you earned $6,240 in commissions last year, that adds $120 per week on top of base pay. A $2,600 year-end bonus adds $50 per week. Leaving them out understates your earnings, which can hurt a credit application or a support calculation.
Taxable fringe benefits work a little differently. If a benefit does not qualify for a federal exclusion, its value is part of gross income. The most common examples are personal use of a company vehicle and employer-paid group-term life insurance coverage above $50,000.11Internal Revenue Service. Publication 525 – Taxable and Nontaxable Income Your employer reports the taxable value in Box 1 of your W-2, so in most cases it is already inside the gross figure on your pay stub. You do not need to add it a second time.
A Worked Example
Add the pieces:
- Base weekly pay (salary ÷ 52, or hourly rate × hours)
- Plus overtime (hours over 40 × 1.5 × regular rate)
- Plus the weekly share of tips, bonuses, and commissions (annual total ÷ 52)
- Plus any taxable fringe benefits not already in W-2 gross pay
For someone earning a $60,000 salary with a $3,120 annual bonus and $1,560 in annual commissions: $1,153.85 base + $60 bonus + $30 commissions = $1,243.85 gross weekly income. A self-employed filer’s Schedule C number already covers everything except non-business income like interest or rent, which you add separately when total household income is what a form is asking for.
Why the Number Has to Be Right
Underreporting income on a tax return can trigger the IRS accuracy-related penalty, which adds 20% to whatever tax you should have paid on the unreported amount, plus interest until you pay in full.12Internal Revenue Service. Accuracy-Related Penalty For individuals, the penalty kicks in when the understatement exceeds 10% of the tax that should have been on the return, or $5,000, whichever is greater.
Overstating income on a loan application is worse. Federal law makes it a crime to knowingly submit false information to influence a financial institution’s lending decision, with penalties of up to $1,000,000 in fines, up to 30 years in prison, or both.13Office of the Law Revision Counsel. 18 USC 1014 – Loan and Credit Applications Generally Lenders also verify income by pulling IRS transcripts, so inflated figures rarely survive underwriting.
In family court, misstating income in either direction can produce a support order that is too high or too low. Judges have broad discretion to impute income based on your qualifications and work history if they suspect the numbers do not reflect reality. Running the calculation carefully the first time is cheaper than litigating a modification later.
