Time Card Calculator
Fill in when you started and finished each day. You get hours per day, the weekly total, how much of it is overtime, and gross pay at your hourly rate.
| Day | Start | End | Break (min) | Hours |
|---|---|---|---|---|
| Monday | — | |||
| Tuesday | — | |||
| Wednesday | — | |||
| Thursday | — | |||
| Friday | — | |||
| Saturday | — | |||
| Sunday | — |
Overtime starts after 40 hours in the week, paid at the multiplier above (1.5× by default). Breaks are treated as unpaid. If an end time is earlier than its start time the shift is counted as crossing midnight. Pay is gross — before income tax, Social Security and Medicare.
Frequently asked questions
How do I calculate hours worked from a time card?
Convert each shift to minutes: end time minus start time minus unpaid break. A 9:00–17:00 shift with a 30-minute break is 480 − 30 = 450 minutes, or 7.5 hours. Add the seven days, then split anything above 40 into overtime for the week. The reason to work in minutes rather than decimals is that 7 hours 50 minutes is 7.83 hours, not 7.5 — rounding that by hand is where most timesheet disputes come from.
Does the calculator handle overnight shifts?
Yes. If the end time is earlier than the start time, it treats the shift as crossing midnight and adds 24 hours — 22:00 to 06:00 with no break comes out as 8 hours. This is how night shifts, security rotations and hospital handovers are normally paid. If a shift genuinely ends at the same clock time it started, enter 24 hours explicitly, since a zero-length shift and a 24-hour shift look identical on a clock.
Are breaks paid or unpaid?
Under federal law, short rest breaks of 5–20 minutes are paid, and meal breaks of 30 minutes or more are unpaid as long as you are completely relieved of duties. That is why the default here is a 30-minute unpaid lunch. Some states tighten this: California requires a second meal period on shifts over 12 hours, and several states require paid rest breaks in addition. If you work through lunch at your desk, that time is generally compensable.
When does overtime start on a time card?
After 40 hours in a single workweek under federal law — and a workweek is a fixed, recurring 168-hour period set by the employer, not necessarily Monday to Sunday. California and a handful of other states also require daily overtime after 8 hours, and double time after 12. This calculator uses the federal weekly rule, so if you are in a daily-overtime state, check each day against 8 hours as well as the weekly total.
