How biweekly overtime is calculated
A biweekly paycheck covers two weeks, but overtime is usually determined one workweek at a time. Estimate the overtime in each week, then add the weeks together for the pay-period view.
Biweekly overtime calculator
Biweekly Overtime Calculator
Estimate a two-week paycheck with overtime. The calculator starts from one workweek, applies overtime to that week, then projects gross and simple take-home pay for a biweekly pay period.

Workweek firstFor a federal FLSA estimate, overtime is tested by workweek. Do not average two weeks together to erase overtime hours.
Gross and take-home estimate
Biweekly overtime paycheck calculator
Enter one typical workweek, then use the Biweekly period to project the two-week paycheck with simple tax and deduction assumptions.
Take-home estimate
Use your own tax-rate assumptions. FICA is estimated at 7.65% and does not model wage bases or special payroll rules.
Advanced mode
Weighted overtime estimate
Use this when one workweek includes more than one hourly rate and straight-time pay for all hours is already counted.

When this page is useful
Use it when you are paid every two weeks and want to estimate how 5, 10, or 15 overtime hours in a week could change the next paycheck.
What to enter for deductions
Because the calculator is set to Biweekly by default, enter deduction amounts for the two-week paycheck, not just one week.
What this does not decide
It does not determine exempt status, state daily overtime, shift differentials, bonuses, commissions, or whether an employer payroll calculation is legally correct.
Frequently asked questions
Can I calculate different overtime in week one and week two?
This page models one typical week and projects it across a biweekly paycheck. If your two weeks differ, run the calculator once for each week and add the gross results.
Why not just enter 80 regular hours and 10 overtime hours?
Federal overtime is tied to each workweek. A two-week paycheck is a payment schedule, not the overtime threshold itself.
Are taxes exact?
No. The take-home estimate uses simple rates you enter. Actual payroll withholding can depend on W-4 elections, benefit settings, wage bases, and local rules.

Important limits
This calculator provides estimates only. It does not decide whether you are legally entitled to overtime, whether an employer is compliant, or what your final paycheck or taxes should be. Overtime rules can vary by jurisdiction, exemption status, bonuses, commissions, employer policy, and other pay types.
