How to use the Time Card Calculator

1Type start and end times for each day you worked (e.g. 9:00 and 17:30, or 9am and 5:30pm) and the break in minutes.
2Set your hourly rate and when overtime starts — 40 hours a week by default, or per day.
3Read total, regular and overtime hours and pay, then copy or download the CSV.

What is the Time Card Calculator?

Hours are shown both as hours:minutes (8:30) and as decimal hours (8.50), which is what payroll and invoices usually need — 15 minutes is 0.25 h, not 0.15. An end time earlier than the start is treated as an overnight shift, so 22:00 to 6:00 counts 8 hours.

Overtime is calculated after a weekly threshold (40 h by default, as under the US FLSA), after a daily threshold, or both, and paid at the multiplier you set (1.5× by default). Rules differ by country, state and contract, so treat the pay figure as an estimate before tax.

Frequently asked questions

How do I convert minutes to decimal hours?

Divide by 60: 45 minutes = 0.75 h, so 7 h 45 min is 7.75 hours.

Are unpaid breaks subtracted?

Yes — whatever you enter as the break is subtracted from that day. Leave it empty for paid breaks.

Is the Time Card Calculator free and private?

Yes. The Time Card Calculator is free, needs no account, and runs entirely in your browser. What you type is never sent to a server or stored.
