Whether you are applying for an apartment, sizing up a car loan, or simply building a household budget, the single number that matters most is your gross monthly income — the total money you earn each month before taxes, insurance premiums, and retirement contributions are taken out. Many hourly workers know their rate per hour but have no idea what that adds up to over a month, and a surprising number of loan and rental applications ask for the monthly figure directly. This monthly income calculator bridges that gap: you enter your hourly wage, the hours you work each week, and the number of weeks you actually work in a year, and it returns your weekly, biweekly, annual, and gross monthly pay.
The result you get is gross, not take-home. Gross income is what lenders and landlords use to qualify you, because it is consistent across employers and easy to verify on a pay stub. Your actual bank deposit will be lower once federal income tax, Social Security, Medicare, state tax, and benefits are withheld — use an after-tax calculator to estimate the net version. For budgeting and qualification purposes, though, gross monthly income is the correct starting point.
How to Use
- Enter your Hourly Wage — the gross rate you earn per hour before any deductions. If you make a mix of regular and overtime rates, use your blended average; you can run the overtime premium separately.
- Set your Hours per Week. A standard full-time schedule is 40 hours. If you regularly work 10–20 hours of overtime, either enter the higher figure or add the overtime pay into the monthly-income line in step 4.
- Choose your Weeks Worked per Year. Most people use 52, but if you take four unpaid weeks off, work a seasonal job, or have unpaid furloughs, enter the realistic number — 48, 50, or whatever matches your year.
- Add any Other Monthly Income — a side hustle, a second job, alimony, child support, or rental income that arrives every month. Leave it at zero if you have none.
- Read the result card: your weekly and biweekly gross pay, your annual gross income, and the highlighted Monthly Gross Income — the figure most applications ask for.
Because the math is transparent, you can stress-test your budget instantly: raise the hourly wage to model a raise, lower the weeks worked to see what a unpaid break does to your monthly cash flow, or add a side gig to confirm it pushes you over the income threshold an apartment requires.
The Monthly Income Formula
This calculator uses the standard wage-annualization convention used by the Bureau of Labor Statistics and every major payroll site:
Annual Gross = Hourly Wage × Hours per Week × Weeks per Year
Monthly Gross = Annual Gross ÷ 12 (+ Other Monthly Income)
Where:
- Hourly Wage is your gross rate per hour.
- Hours per Week is your average worked hours.
- Weeks per Year is usually 52, but adjust for unpaid time off.
- The result is divided by 12 because there are twelve months in a year.
Worked example on a $25 hourly wage at 40 hours per week for 52 weeks: annual gross is 25 × 40 × 52 = $52,000, and dividing by 12 gives a gross monthly income of $4,333.33. The same paycheck biweekly is $52,000 ÷ 26 = $2,000, which matches the familiar "two-thousand-dollar check" many hourly workers recognize. Notice how the monthly figure ($4,333) is a little less than two biweekly checks ($4,000) would suggest — because twelve monthly paychecks vs. twenty-six biweekly checks do not line up exactly. Dividing the annual figure by 12 removes that confusion.
Why Gross vs. Net Matters
Lenders, mortgage underwriters, and rental applications ask for gross income because it is verifiable and consistent. A landlord typically wants your rent to stay under roughly one-third of your gross monthly income, and mortgage lenders apply a front-end housing ratio of about 28% of gross income. If you budget off your net take-home pay instead, you may underestimate what you qualify for and be shown apartments or loans you cannot actually afford on paper. Use the gross number here for applications; use your net take-home for day-to-day spending.
Examples
Example 1 — The standard full-time worker. You earn $25 per hour, work 40 hours a week, all 52 weeks of the year, with no other income. The calculator shows weekly gross of $1,000, biweekly gross of $2,000, annual gross of $52,000, and a highlighted monthly gross income of $4,333.33. On a rental application asking for monthly income, you enter $4,333.
Example 2 — Part-time with a side gig. A barista earns $18 per hour, averages 25 hours a week, works 50 weeks (taking two unpaid weeks off at Christmas), and makes an extra $400 per month delivering food. Annual wages are 18 × 25 × 50 = $22,500, which is $1,875 per month in wages; adding the $400 side income gives a gross monthly income of $2,275. Entering 52 weeks instead of 50 would overstate the monthly figure by roughly $75.
Example 3 — The high earner stress test. A contract worker bills $120 per hour, logs 40 hours a week, and works a full 52 weeks. Annual gross is $249,600, biweekly gross is $9,600, and monthly gross income is $20,800. Running this before shopping for a home or a luxury car confirms the income side of the DTI ratio before the lender does.
FAQ
How do I calculate my gross monthly income from an hourly wage?
Multiply your hourly wage by the hours you work per week, then by the weeks you work per year to get your annual gross income, and finally divide by 12. For example, $25/hour × 40 hours × 52 weeks = $52,000 per year, and $52,000 ÷ 12 = $4,333.33 per month. Add any other regular monthly income to that result.
What is the difference between gross and net monthly income?
Gross monthly income is your total earnings before taxes and deductions; net monthly income is what actually lands in your bank account after federal income tax, Social Security, Medicare, state tax, and benefit premiums are withheld. Lenders and landlords use gross income on applications, while your personal budget should use net income.
How do I convert a biweekly paycheck to monthly income?
Take your biweekly gross pay and multiply by 26 to get the annual figure, then divide by 12. A $2,000 biweekly check × 26 = $52,000 per year, which is $4,333.33 per month. Never multiply a biweekly check by two and call it monthly — twelve months do not equal twenty-six biweekly periods.
How many weeks should I use per year?
Use 52 if you work the full year with no unpaid time off. If you take unpaid vacation, furloughs, or have a seasonal schedule, enter the realistic number of paid weeks — for example, 48 if you take four unpaid weeks off. This keeps your monthly income estimate honest rather than inflated.
Do I include overtime in my monthly income?
You can, but be consistent. If overtime is reliable year-round, add your overtime hours into the hours-per-week field. If it is occasional or seasonal, add an average monthly overtime amount into the Other Monthly Income field instead. Lenders usually average overtime over the last two years when verifying.
Should side gigs and rental income be included?
Yes, if the income is regular and verifiable. Add it to the Other Monthly Income field. Note that some lenders require side or rental income to have a two-year history before counting it, and they may discount it to account for variable months.
