How to use this calculator
- Enter the clock-in and clock-out time for each day you worked — leave a day empty to skip it.
- Add the unpaid break in minutes for each day — lunch and other breaks are subtracted from that day.
- Read the results — each day shows its decimal hours, and the weekly total, hours:minutes, average per day worked and overtime over 40 hours update live. Enter an hourly rate to get your weekly pay.
How are weekly working hours calculated?
For each day, the working time is the span between clock-in and clock-out minus unpaid breaks; the weekly total is the sum of all days. A 09:00–17:00 shift with a 30-minute lunch is 7.5 hours, so five such days give 37.5 hours for the week. This calculator counts every minute — no rounding to quarters or tenths.
Overnight shifts
If a clock-out time is earlier than (or equal to) the clock-in time, that day crosses midnight: a 22:00–06:00 shift counts as 8 hours, not negative or zero. Each row is resolved independently before the weekly total is summed, so a night shift that ends on the next calendar day still belongs to the row where it started.
Overtime over 40 hours
In the United States, the FLSA requires overtime pay at time-and-a-half once a non-exempt employee works more than 40 hours in a workweek. The calculator shows the hours above 40 as a separate stat — multiply them by 1.5 × your hourly rate to estimate overtime pay. Rules differ by country and contract, so check which threshold applies to you.
Why decimal hours?
Timesheets and payroll systems record hours in decimal form, because 7 hours 30 minutes must become 7.5 before multiplying by an hourly rate. Every day in the table is shown in that decimal form: minutes divided by 60. 15 minutes is 0.25, 30 minutes is 0.5, and 45 minutes is 0.75.
Frequently asked questions
How do I calculate my working hours for a week?
For each day, subtract the clock-in time from the clock-out time and subtract unpaid breaks, then sum all days. A 09:00–17:00 shift with a 30-minute lunch counts as 7.5 hours, so five such days give 37.5 hours. The calculator above does this for every day at once and updates as you type.
How does the calculator handle overnight shifts?
If a clock-out time is earlier than the clock-in time, that day is treated as crossing midnight and 24 hours are added — a 22:00–06:00 shift counts as 8 hours. Each row is resolved independently before the weekly total is summed.
How many hours is a full-time week?
It depends on the country. 40 hours per week is the standard in the United States, France sets 35 hours by law, and the EU Working Time Directive caps the average working week at 48 hours including overtime. Check your local labour law or employment contract for the figure that applies to you.
