Two workweeks · OT done right · 2026Bi-Weekly Time Card Calculator
Add up two workweeks of hours. Overtime is figured the correct way — per week (over 40 each week), not averaged over 80 — with a clear Week 1 / Week 2 split, totals and pay.
How a bi-weekly time card works
Bi-weekly means you're paid every two weeks on a fixed weekday — 26 paychecks a year. A bi-weekly pay period is two full workweeks, so a standard full-time period is 80 hours. The catch is overtime, and most calculators get it wrong.
Why per-week, not per-period
Under the federal FLSA, overtime is hours over 40 in a single fixed 7-day workweek — paid at 1.5× — and employers cannot average two weeks together to avoid it. Whether your pay period is bi-weekly, semi-monthly or monthly, the overtime math always comes back to the individual workweek.

Frequently asked questions
How is overtime calculated on a bi-weekly time card?
Per workweek, not per period. Apply the 40-hour rule to Week 1 and Week 2 separately, then add. You can't total the two weeks and only pay over 80.
45 hours one week, 35 the next — do I get overtime?
Yes — 5 OT hours from Week 1. The 80-hour total doesn't matter; overtime is figured per week.
Is bi-weekly the same as semi-monthly?
No. Bi-weekly = every 2 weeks, 26/yr, lines up with workweeks. Semi-monthly = twice a month on fixed dates, 24/yr, doesn't.
How many hours are in a bi-weekly pay period?
80 for full time (two 40-hour weeks). Your actual hours depend on what you worked.
