Decimal hours are rounded to two places. Always follow your employer's official rounding policy for payroll.
How to use this work hours calculator
- Enter clock-in and clock-out times.
- Add the unpaid break in minutes.
- Calculate the paid duration.
Calculate paid work hours after an unpaid break
Enter the clock-in time, clock-out time and only the minutes that are unpaid. The calculator subtracts the break from the time on site, then shows both hours and minutes and decimal hours. For example, 09:00 to 17:30 with a 30-minute unpaid break is 8 hours of paid time, or 8.00 decimal hours.
Why payroll uses decimal hours
Hours and minutes are easier to read, while many payroll and timesheet systems require a decimal value. Thirty minutes is 0.50 hours, 15 minutes is 0.25 hours and 45 minutes is 0.75 hours. This tool rounds its displayed decimal result to two places; use the employer's stated rounding rule when submitting a timesheet.
Overnight shifts and break rules
If clock-out is earlier than clock-in, this calculator treats the shift as ending the following day. It deducts the break once and prevents an unpaid break longer than the shift. It does not decide whether a break is paid, calculate overtime or replace an employer's timekeeping policy.
Choose the right time tool
Use this calculator for one paid shift with an unpaid break. Use the existing Time Duration Calculator for elapsed time without a break, or the Date Calculator when you need to move a date rather than calculate shift hours.
