How to use this biweekly time card calculator

A common payroll myth is that biweekly overtime waits until 80 hours. Under the FLSA, overtime is due when you exceed 40 in a workweek. This biweekly time card calculator keeps two separate 40-hour clocks so week 1 OT cannot hide in a short week 2. Enter hours per day, not punches.

Formula

Week 1 = days 1–7, Week 2 = days 8–14. OT each week = max(0, week hours − 40). Gross = sum of each week’s regular × wage + OT × wage × multiplier.

Worked example

Two identical 40-hour weeks at $20 is $1,600 with $0 OT. A 45-hour week plus a 35-hour week is 5 OT hours in week 1 only — not a 80-hour pool.

Frequently asked questions

Is overtime after 80 hours on a biweekly check?

Usually no. Federal OT is per 40-hour workweek even if you are paid every two weeks.

What if my workweek is Sunday–Saturday?

Put Sunday in the first slot of each week. Labels are Mon–Sun for convenience; the math is seven-day blocks.

Clock times?

Convert each day with Hours Worked, then enter the decimals here—or use two weekly Time Cards.
