Hours Calculator

How the Total Is Calculated

This calculator takes your clock-out time minus your clock-in time to get the raw time on the clock, then subtracts any unpaid break to get net hours worked. If clock-out is earlier than clock-in (for example, a shift that starts at 22:00 and ends at 06:00), it assumes an overnight shift and adds 24 hours before subtracting, so you don't need to change dates to calculate an overnight total. The decimal-hours figure — the format most payroll systems expect — is simply the net minutes worked divided by 60 (so 7 hours 45 minutes becomes 7.75, not 7.45).

Decimal Hours vs. Minutes: A Common Payroll Mix-Up

A frequent timesheet error is writing 7:45 (7 hours, 45 minutes) as "7.45 hours" for payroll. Since an hour has 60 minutes, not 100, 45 minutes is 45/60 = 0.75 of an hour, so the correct decimal figure is 7.75. This calculator handles that conversion for you automatically, showing both the human-readable hours-and-minutes total and the decimal figure side by side.

Tracking a Full Week Instead of One Shift

This tool is built for entering a single shift at a time. If you need to add up several shifts across a pay period — including daily or weekly overtime rules — use the time card calculator instead. For general elapsed-time math between two arbitrary clock times without payroll framing, the time calculator can help too.
