Working Hours Calculator
Turn a week of start and finish times into total hours. Enter when each day started and ended and how long the breaks were; the calculator handles shifts that run past midnight, shows each day and the week in hours and minutes and in decimal hours, splits out overtime above your threshold, and calculates gross pay if you enter an hourly rate.

An end time earlier than the start counts as a shift past midnight. Leave a day empty if it was not worked.
Overtime rules differ by country, employer and contract; adjust the threshold and multiplier to match yours.

Working Hours Calculator FAQ
How do I convert hours and minutes to decimal hours?
Divide the minutes by 60: 7 hours 30 minutes is 7.5 hours; 7 hours 45 minutes is 7.75. Payroll systems usually need decimal hours.
How are night shifts handled?
If the end time is earlier than the start, the shift is treated as ending the next day: 22:00 to 06:00 is 8 hours before breaks.
Are breaks paid?
That depends on your contract and local law. The calculator subtracts the break minutes you enter; leave them at 0 for paid breaks.
How is overtime calculated?
Hours above the weekly threshold are overtime and are paid at the hourly rate times the multiplier. Some places calculate overtime per day instead; adjust the inputs or calculate days separately.
Does it handle daylight-saving changes?
No. On the night clocks change, a shift is one hour longer or shorter than the clock times suggest; adjust that day manually.
Is the pay figure after tax?
No. It is gross pay before tax and deductions.
Getting hours right
Small errors in timesheets add up. Ten minutes miscounted every day is almost an hour a week, and decimal conversions are a classic source of mistakes: 7 hours 30 minutes is 7.5 hours, not 7.3. A calculator that does the conversion and shows both forms removes that risk.
Each day’s hours are the time between start and end minus unpaid breaks. Shifts that cross midnight need care, because a naive subtraction produces a negative number; here an end time earlier than the start time is read as the next day. Days not worked are simply left empty.
Overtime rules vary. Many jurisdictions and contracts define overtime as hours above 40 a week, paid at one and a half times the normal rate, but daily thresholds, double time and exemptions for certain jobs are common too. The threshold and multiplier are inputs so that you can match your own rules.
Keep records. Employees and employers both benefit from a clear account of hours worked, especially where pay depends on them. Note the times when they happen, not from memory at the end of the week, and keep the timesheets for as long as wage records must be kept where you work.
