How to calculate your work hours

Calculating a weekly time card is a three-step process, and the calculator above handles all of it for you:

  1. 1. Find each day's worked time. Subtract your clock-in time from your clock-out time. Example: 9:00 AM to 5:00 PM = 8 hours.
  2. 2. Deduct unpaid breaks. A 30-minute unpaid lunch turns that 8-hour shift into 7.5 paid hours.
  3. 3. Add up the week and convert to decimal. Payroll pays in decimal hours, so 37 hours and 30 minutes becomes 37.50.

To get gross pay, multiply your decimal hours by your hourly rate. If overtime applies, hours past the threshold (8 per day or 40 per week) are paid at 1.5× or 2× your rate.

Frequently asked questions

How do I calculate my total hours worked in a week?

Enter your clock-in and clock-out time for each day, then subtract any unpaid break minutes. This time card calculator does it automatically: it totals each day, deducts your breaks, and sums the week into both hours-and-minutes (8:30) and decimal hours (8.50) so you can plug the number straight into payroll.

How do breaks affect my hours?

Unpaid breaks (like a 30-minute lunch) are subtracted from the time between clock-in and clock-out. If you clock in at 9:00 AM, clock out at 5:00 PM, and take a 30-minute unpaid lunch, you worked 7.5 hours, not 8. Enter the break length in minutes in the "Break" column and it is deducted for that day.

How is overtime calculated?

Under U.S. federal law (FLSA), most hourly employees earn 1.5× their regular rate for hours worked beyond 40 in a workweek. Choose "After 40h / week" for the federal rule, or "After 8h / day" for states like California that use a daily overtime threshold. The calculator splits regular vs. overtime hours and applies your chosen multiplier (1.5× or 2×).

What is the difference between hours:minutes and decimal hours?

Payroll systems pay in decimal hours, not minutes. 8 hours and 30 minutes is written 8:30 in clock time but 8.50 in decimal (because 30 minutes is half an hour). The calculator shows both — use the decimal column when entering hours into a payroll system.

Does this work for overnight shifts?

Yes. If your clock-out time is earlier than your clock-in time (for example, in at 10:00 PM and out at 6:00 AM), the calculator assumes the shift crossed midnight and counts it as 8 hours.

Is my data saved and is it private?

Your entries are saved only in your own browser (localStorage) so the week is still there when you come back. Nothing is uploaded to a server and no account is required. Click "Clear" to wipe the time card from your browser.
