This timesheet calculator adds up a full week of work hours from your clock-in and clock-out times. Enter a start and end time for each day, subtract any unpaid break in minutes, and it converts the messy hours-and-minutes into clean decimal hours and a weekly total. Add your hourly rate and it also works out your gross pay.
It handles the two things people most often get wrong by hand: breaks and overnight shifts. Unpaid breaks are deducted per day, and a shift that runs past midnight (for example 22:00 to 06:00) is counted correctly rather than coming out negative. Turn on the overtime option to split anything over 40 hours a week into overtime paid at 1.5×.
How to use it
- 1For each day you worked, enter the start time and end time.
- 2Add any unpaid break in minutes — it's subtracted from that day's hours.
- 3Leave days off blank; they simply count as zero hours.
- 4Enter your hourly rate and currency to see gross pay.
- 5Keep 'Overtime over 40 h/week' on to pay hours above 40 at time-and-a-half.
Frequently asked questions
How are hours and minutes turned into decimal hours?+
The calculator converts each time to minutes, finds the difference, subtracts your break, then divides by 60. So 8 hours 30 minutes becomes 8.50 hours. Decimal hours are what you multiply by an hourly rate to get pay — 8.5 × $20 = $170.
Does it handle overnight shifts?+
Yes. If the end time is earlier than the start time (for example a shift from 22:00 to 06:00), the calculator assumes it crossed midnight and adds 24 hours, giving 8 hours rather than a negative number.
How is overtime calculated?+
With the overtime option on, the first 40 hours in the week are paid at your normal rate and every hour beyond 40 is paid at 1.5× (time-and-a-half). This mirrors the common US FLSA rule, but overtime laws vary by country and state — check your local rules and employment contract.
Should I include breaks?+
Only include unpaid breaks — enter their length in minutes so they're deducted. If your breaks are paid, leave the break field at 0 so those minutes stay in your total. This is an estimate for your own tracking, not official payroll.
