Timesheet Calculator
Add up clock-in and clock-out times across a week to calculate total hours worked and overtime pay, free in your browser.

If the end time is at or before the start time it is treated as an overnight shift. Estimate only — check your award/contract for exact overtime and break rules. Calculations run in your browser.
How to use this calculator
- Enter the start and end time of the shift (overnight shifts are handled automatically).
- Enter the unpaid break in minutes.
- Optionally set an overtime threshold and an hourly pay rate to see regular vs overtime hours and pay.
How it works
The Timesheet Calculator works out hours worked between a clock-in and clock-out time, subtracts the unpaid break, and shows the result as both decimal hours and hours:minutes. If the end time is at or before the start time it is treated as an overnight shift that rolls into the next day.
If you set an overtime threshold, hours above it are counted as overtime; with a pay rate entered, regular hours are paid at the rate and overtime at 1.5×. All of it is an estimate to check against your award, contract or roster rules.
Worked example
7:00 to 18:00 with a 1-hour break, overtime after 8 h at $30. That is 11 hours minus a 1-hour break = 10 hours: 8 regular ($240) plus 2 overtime at 1.5× ($90), for $330 total.
Tips
- Decimal hours (e.g. 7.5) are what most payroll systems expect; the h:mm figure is for reading at a glance.
- Overtime and break rules vary by award and contract — use this as a check, not the final word.
Frequently asked questions
How are overnight shifts handled?
If the end time is the same as or earlier than the start time, the calculator assumes the shift crosses midnight and adds 24 hours, so a 22:00–06:00 shift correctly comes out as 8 hours.
How is overtime calculated?
Any hours worked beyond the overtime threshold you set are counted as overtime and, if you enter a pay rate, paid at 1.5× that rate. Leave the threshold blank to treat all hours as regular.
Is the break paid?
The break you enter is treated as unpaid and subtracted from the worked hours. If your break is paid, set it to 0.
