Weekly Time Card Calculator

How to use this time card calculator

1. Type each day's clock-in and clock-out time. You can write it however you like — 9, 9:00, 9am, 0900, or 17:30 all work.
2. Set the lunch break in minutes. Use "Apply to all days" to reuse the same break, or press "+ break" on any day for a second unpaid break.
3. Optionally pick a rounding rule (5, 6, or 15 minutes) and switch on overtime with your weekly threshold and hourly rate.
4. Read the weekly total in both hh:mm and decimal. Regular, overtime, and gross pay appear when overtime is enabled.
5. Press Print timesheet for a clean paper copy or Export CSV to open the totals in a spreadsheet — no account required.

How weekly hours are actually calculated

A time card total is simpler than it looks, but three details trip people up: breaks, overnight shifts, and rounding. Here is exactly what this calculator does with each row.

Gross time minus unpaid breaks

For each day, the calculator converts your clock-in and clock-out into minutes since midnight, subtracts the earlier from the later, and then removes every break you entered. A shift from 9:00 to 17:00 is 480 gross minutes; a 30-minute lunch leaves 450 paid minutes, which is 7:30 or 7.5 hours. Breaks are unpaid time, so they always come out of the paid total — that is why a "time card calculator with lunch break" gives a smaller number than raw clock time.

Overnight shifts that cross midnight

When your clock-out is earlier than your clock-in — say 22:00 to 06:00 — the shift clearly ran past midnight. The calculator detects this automatically and adds 24 hours, returning 8:00 instead of a negative number. You never have to split an overnight shift into two rows.

Punch rounding and the 7-minute rule

Many employers round each punch to a set interval so payroll lands on tidy quarter-hours. Choose 15-minute rounding to apply the well-known 7-minute rule: a punch at 9:07 rounds back to 9:00, but 9:08 rounds forward to 9:15. Five- and six-minute options are there for shops that round to the nearest tenth of an hour. Rounding is applied to the in and out punches before breaks are subtracted, which matches how most payroll systems behave.

Overtime and gross pay

Turn on overtime to split hours above your weekly threshold — 40 hours under the U.S. Fair Labor Standards Act, but editable — into regular and overtime buckets. Enter an hourly rate and the calculator multiplies overtime hours by 1.5 to show regular pay, overtime pay, and gross pay. These figures are estimates to help you check a paycheck, not official payroll.

Two output formats

Every total appears twice: as hours and minutes (7:30) for reading, and as decimal hours (7.5) for payroll systems that expect a decimal. If you only need to convert between the two, the decimal hours converter has a full minute-by-minute chart.
