Work Hours Calculator
Add up hours worked from clock-in and clock-out, minus breaks.
Breaks are treated as unpaid. End times earlier than the start are assumed to be the next day.
Turning a shift into paid hours
The calculator finds the gap between your start and end times, subtracts any unpaid break, and reports the result as both hours-and-minutes and a decimal number of hours for payroll.
hours = (end − start − break)
The decimal form is the one that trips people up: half an hour is 0.5 hours, not 0.30. Multiplying the decimal hours by your rate gives the day’s pay, and a quick five-times estimate sketches the week.
Clocking in at 09:00 and out at 17:00 with a 30-minute break is 7.5 hours (7 h 30 m). At $20 an hour that is $150 for the day, or about $750 across a five-day week.
Keeping an accurate record
Small daily rounding adds up over a month, so logging real start and end times beats estimating. Whether you are an hourly worker checking a payslip or a freelancer billing time, a clear decimal-hours figure keeps the maths honest.
Worth noting
- Decimal vs clock. 7:30 on the clock is 7.5 decimal hours — never 7.3.
- Unpaid breaks. Set the break to match your contract; paid breaks should be entered as zero.
- Overtime rules vary. This shows plain hours; premium rates depend on your agreement.
