How to use this gross monthly income calculator

A gross monthly income (GMI) calculator converts your pay into the amount you earn per month before taxes and deductions. Lenders, landlords and car finance companies often ask for this figure, sometimes written as “GM income”. Enter an hourly wage, a daily rate, a weekly, bi-weekly or semi-monthly paycheck, a monthly or annual salary, or a year-to-date total from your pay stub, and add overtime or other regular income.

What is gross monthly income?

Gross monthly income is your total earnings for a month before income tax, social security, health insurance, retirement contributions or any other deductions. It is different from net or take-home pay, which is what reaches your bank account. Because many people are not paid exactly once a month, the usual method is to work out a yearly total and divide by 12.

How to calculate gross monthly income from hourly or bi-weekly pay

For hourly pay, multiply the hourly rate by hours per week and by 52 weeks, then divide by 12: 18 × 40 × 52 ÷ 12 = 3,120. For bi-weekly pay there are 26 paychecks a year, so multiply one check by 26 and divide by 12: 2,300 × 26 ÷ 12 ≈ 4,983. Multiplying a bi-weekly check by 2 understates income, because two months a year have three paychecks.

How lenders use your gross monthly income

Auto lenders, mortgage lenders and landlords compare your payments with your gross monthly income. A common approach for variable pay is to take the year-to-date gross from your latest pay stub and divide by the months it covers. Use the year-to-date option to check that figure. Each lender sets its own rules on what income it accepts.

Gross Monthly Income formulas, explained

Hourly

GMI = hourly rate × hours per week × weeks per year ÷ 12

Add overtime: OT hours × rate × multiplier × weeks ÷ 12.

Bi-weekly and semi-monthly

Bi-weekly: check × 26 ÷ 12 · semi-monthly: check × 24 ÷ 12

Bi-weekly is every two weeks; semi-monthly is twice a month.

Annual salary

GMI = annual salary ÷ 12

Year-to-date (pay stub)

GMI = YTD gross ÷ months covered

Example: 38,400 earned by the end of August (8 months) = 4,800 per month.

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

Multiply your hourly rate by the hours you work each week, multiply by 52, then divide by 12. At 25 per hour and 40 hours a week: 25 × 40 × 52 ÷ 12 ≈ 4,333 per month.

How do I calculate gross monthly income from a bi-weekly paycheck?

Multiply the gross amount of one paycheck by 26 (the number of bi-weekly paydays in a year) and divide by 12. Use the gross amount from the pay stub, not the net deposit.

Find the year-to-date (YTD) gross earnings on your latest pay stub and divide by the number of months the YTD period covers. Choose “Year-to-date (pay stub)” and enter both numbers.

What is the difference between gross and net monthly income?

Gross income is before deductions; net income is what you take home after tax, insurance and retirement contributions. Gross is always the higher number.

How much of my gross monthly income should go to rent or a car payment?

A widely used guideline is to keep housing near 30% of gross monthly income and total debt payments near 36%, but every lender and landlord sets its own limits. The calculator shows 30% and 36% of your figure for reference.

Methodology & assumptions

Calculations run in your browser using the formulas and assumptions explained on this page. Intermediate values retain full floating-point precision; displayed amounts are rounded. Pay is converted to an annual figure (hourly × hours × weeks, weekly × weeks, bi-weekly × 26, semi-monthly × 24, monthly × 12, or YTD ÷ months × 12), overtime and other monthly income are added, and the total is divided by 12. All figures are gross (before tax). Lenders may average variable income differently or exclude some income types. This tool is independent and not affiliated with any lender.
