Biweekly Pay Calculator
At $25 an hour for 40 hours a week across 52 paid weeks, gross biweekly pay is $2,000. This biweekly pay calculator converts either an hourly wage or an annual salary into estimated gross biweekly pay. Use your actual paid weeks per year so the weekly and biweekly figures match your schedule, then check the annual, monthly, and weekly equivalents.
Quick answer
Hourly pay first converts to annual gross pay using hourly wage x hours per week x paid weeks per year.
Use 52 for a fully paid year. If you plan around unpaid weeks off, enter the number of weeks you actually receive pay.
What this tells you
- •Hourly pay first converts to annual gross pay using hourly wage x hours per week x paid weeks per year.
- •Salary pay starts with your gross annual salary, then spreads that total across the paid weeks you enter.
- •Biweekly gross pay equals weekly gross pay x 2, so fewer paid weeks produce larger weekly and biweekly amounts from the same annual total.
- •All money values are rounded to 2 decimal places.
How to Use
- 1Choose whether you want to start from an hourly wage or an annual salary.
- 2Enter your gross pay amount for the path you selected.
- 3Set paid weeks per year. Use 52 for a fully paid year or a lower number if you expect unpaid weeks off.
- 4If you chose hourly wage, enter hours worked per week.
- 5Calculate to see your estimated gross biweekly pay plus annual, monthly, and weekly equivalents.
How It Works
Formula
Hourly path: annual gross pay = hourly wage x hours per week x paid weeks per year
Salary path: annual gross pay = annual salary
Weekly gross pay = annual gross pay / paid weeks per year
Biweekly gross pay = weekly gross pay x 2The calculator first sets a gross annual pay figure. For hourly workers it multiplies wage, weekly hours, and paid weeks. For salaried workers it uses the annual salary you enter. It then divides annual gross pay by paid weeks to get weekly gross pay, doubles that amount for biweekly gross pay, and divides annual pay by 12 for the monthly equivalent.
Calculation note: values are processed in the order shown above, using the current input units.
Worked Examples
$25 an hour with 2 unpaid weeks
Annual gross pay is 25 x 40 x 50 = $50,000. Dividing by 25 biweekly pay periods gives $2,000 per paycheck. The same inputs also equal $1,000 per week and about $4,166.67 per month.
$78,000 salary paid across 52 weeks
$78,000 divided by 26 biweekly pay periods is $3,000 per paycheck. That same salary equals $1,500 per week and $6,500 per month before deductions.
Hourly Wage to Gross Biweekly Pay
Common hourly wages converted to gross biweekly pay at 40 hours per week across 52 paid weeks.
| Hourly wage | Annual gross pay | Biweekly gross pay |
|---|---|---|
| $15 | $31,200 | $1,200 |
| $20 | $41,600 | $1,600 |
| $25 | $52,000 | $2,000 |
| $30 | $62,400 | $2,400 |
| $40 | $83,200 | $3,200 |
Each row assumes 40 paid hours per week and 52 paid weeks per year. Change paid weeks if you expect unpaid time off or seasonal gaps.
How the paid-weeks assumption changes the result
The hourly path builds annual gross pay from rate times weekly hours times paid weeks. At $25, 40 hours, and 50 paid weeks, annual pay is $50,000. Weekly pay remains $1,000, and the modeled two-week amount remains $2,000. Unpaid weeks lower the annual total rather than changing the rate for weeks worked.
The salary path behaves differently. It starts with the entered annual salary and divides by paid weeks. A $78,000 salary over 52 paid weeks gives $1,500 per week and $3,000 per two-week period. If paid weeks is changed to 50, the model gives $1,560 per paid week and $3,120 per two-week period while annual salary stays $78,000.
That salary behavior may not match an employer's payroll. Many annual salaries are spread over 26 biweekly dates even when the employee does not work every week, while some school, seasonal, or contract arrangements use another distribution. Enter the employer's actual paid-week convention, and use annual salary divided by the actual number of checks when payroll dates are known.
Biweekly means every 14 days. A standard year is commonly modeled with 26 checks, but calendar alignment can occasionally create an extra payroll date under an employer's schedule. Semimonthly means 24 checks on two dates per month. The monthly figure on this page is annual gross divided by 12, not a prediction of deposits in a month with two or three checks.
The hourly model applies one rate to every hour. It does not identify overtime, double time, paid breaks, shift differentials, holiday premiums, on-call pay, tips, commissions, bonuses, or paid leave. If different hours earn different rates, calculate each component under the applicable payroll rules and combine them separately.
Gross pay is before federal, regional, and payroll taxes plus benefits, retirement contributions, garnishments, union dues, and other deductions. Net pay can also change from check to check as withholding limits, benefit elections, reimbursements, or deductions change. This tool does not convert gross to net.
All outputs round to cents. Official payroll may round time punches, individual earnings lines, taxes, and deductions in a different order. A cent-level match with this estimate does not verify that a wage statement follows a contract or labor law.
Common mistakes
- Confusing biweekly with semimonthly. Biweekly means every 2 weeks, usually 26 checks a year, while semimonthly usually means 24 checks.
- Leaving paid weeks at 52 when you know you have unpaid time off. Fewer paid weeks raise the weekly and biweekly amounts tied to the same annual total.
- Comparing gross biweekly pay with a take-home paycheck. Taxes, benefits, retirement contributions, and other deductions lower the amount you actually receive.
- Assuming the hourly path pays overtime premiums after 40 hours. Every entered hour uses one rate.
- Using 50 paid weeks for a salary that is actually distributed across all 26 biweekly payroll dates.
- Treating the monthly annual average as the exact amount received in each calendar month.
Limitations
This calculator accepts an integer from 1 through 52 as paid weeks. Hourly mode multiplies one rate and weekly-hour value by those weeks. Salary mode keeps annual salary fixed and divides it across the entered weeks, then doubles weekly pay. It does not model actual payroll dates, extra pay periods, partial weeks, time-punch rounding, overtime, double time, leave, holiday pay, premiums, bonuses, tips, commissions, reimbursements, taxes, benefits, deductions, currency, or labor-law rules. Monthly pay is an annual average. Employer calendars and salary-distribution agreements may not match the paid-weeks model.
