Time Card Calculator

Worked examples

Standard week

Five days of 9:00 AM–5:30 PM with a 30-minute lunch → 8 hours a day, 40:00 total, no overtime.

Overtime week

Five days of 8:00 AM–6:00 PM with no break → 50:00 worked, 40:00 regular, 10:00 overtime under federal rules.

California daily rules

One day 6:00 AM–8:00 PM → 14 hours: 8 regular, 4 overtime (hours 9–12), 2 double time (over 12).

How it is calculated

Hours per day = (out − in) − break, with the out time taken as the next day when it is earlier than the in time. Under federal rules, hours in a 7-day week beyond 40 are overtime. Under California rules, hours beyond 8 in a day are overtime, beyond 12 are double time, and regular hours beyond 40 in the week become overtime; daily overtime is not counted twice. Rounding applies to each punch before calculation.

Questions people ask

How do you calculate a time card with lunch?

Subtract the unpaid lunch from each day. 9:00 AM to 5:30 PM is 8.5 hours on the clock; minus a 30-minute lunch gives 8 paid hours. Enter the lunch length in the break column.

How do I convert time card minutes to decimal?

Divide the minutes by 60. 7 h 45 m is 7.75; 8 h 10 m is 8.17. The totals show both formats.

What is 6-minute rounding?

Punches are rounded to the nearest tenth of an hour (6 minutes), a common payroll setting. 8:03 becomes 8:00 and 8:04 becomes 8:06. Pick it in the rounding menu.

How does biweekly overtime work?

Overtime is calculated per workweek, so the calculator treats rows 1–7 and 8–14 as separate weeks; 45 hours in week one and 35 in week two gives 5 overtime hours.

Does the calculator save my time card?

Your entries live in the page address. Copy the link to keep or share the card, or download the CSV. Nothing is stored on our servers.

Can I print it for my employer?

Yes. The print button lays out the days, totals and gross pay on one page; the timesheet templates offer blank versions.
