From clock times to a checkable weekly total.
For each shift, calculate the elapsed time between clock-in and clock-out, subtract only unpaid breaks, then add the daily results. Ready Hours also shows decimal hours because many payroll systems expect 7.50 rather than 7 hours 30 minutes.
Worked example
8:30 AM–5:15 PM with a 45-minute unpaid breakThe elapsed time is 8 hours 45 minutes. Subtracting 45 minutes leaves 8 hours, displayed as 8:00 and 8.00 decimal hours.
Overnight shifts
When the end time is earlier than the start time, the calculator treats the shift as ending the following day. A 10:00 PM start and 6:00 AM finish is eight elapsed hours before break deductions.
Overtime is a setting, not legal advice
The weekly threshold separates hours for estimation, but it does not decide whether a person is legally eligible for overtime or which rate applies. Those rules can vary by country, state or province, occupation, agreement and workweek definition.

Common questions
Work-hours calculator FAQ
How are unpaid breaks handled?
The break duration is subtracted from elapsed shift time. Do not subtract a paid break.
Why are 7 hours 30 minutes shown as 7.50?
Thirty minutes is half of a 60-minute hour. Decimal time is not written like clock minutes: 7:30 becomes 7.50, not 7.30.
Can it calculate an overnight shift?
Yes. If clock-out is earlier than clock-in, the calculator assumes clock-out occurs on the next day.
Is the estimated pay an official payroll result?
No. It is a planning estimate based on the rate and threshold entered. It does not account for taxes, premiums, rounding policies or every overtime rule.
Are my time entries uploaded?
No. The current calculator performs its arithmetic in your browser.
