If you're paid every two weeks, it's tempting to think of overtime as anything beyond 80 hours in the pay period. That's actually wrong under U.S. federal law. The Fair Labor Standards Act (FLSA) defines overtime around a fixed, recurring 7-day workweek — not your pay schedule. That means a biweekly time card calculator has to check the 40-hour threshold separately for Week 1 and Week 2, even though you only get paid once for both of them combined. Work 45 hours in Week 1 and 35 in Week 2, and you still owe 5 hours of overtime for Week 1 — you can't average it out to 80 total and call it even.

This calculator handles that distinction automatically. Enter your clock-in and clock-out times for each day across both weeks, and the tool calculates regular and overtime hours independently per week before combining them into a single biweekly pay period gross pay figure. Use the Quick Fill tool to apply one shift template across your Monday–Friday schedule for both weeks at once if your hours are consistent, then adjust individual days as needed.

The results panel shows your combined regular hours, combined overtime hours, and total hours for the full pay period, plus a per-week breakdown so you can see exactly which week (if any) triggered overtime. Toggle the overtime switch off if your employer doesn't apply time-and-a-half, or if you're an exempt employee estimating a straight hourly total instead.
