This calculator provides a mathematical estimate. Break, overtime, rounding, rest and pay rules vary by country, contract and collective agreement.
The displayed amount is a gross estimate. It does not automatically include taxes, contributions, deductions or local payroll rules.
How the calculation works
The calculator converts each clock time into minutes from midnight, totals the work periods, subtracts unpaid breaks and then classifies optional overtime.
Net worked time
net = sum(work periods) - unpaid breaksOvernight shifts add 1,440 minutes to the end time before subtracting the start time.
Decimal hours
decimal hours = total minutes / 60The decimal value is useful when you need to enter hours in a payroll or invoicing system.
Overtime pay
gross estimate = normal × rate + overtime × rate × multiplierDaily overtime is classified first, then weekly overtime is applied only to hours still considered normal.
Work hours guide
Breaks and unpaid time
Enter a break as minutes for each day. When the break is longer than the worked period, the calculator stops and shows a validation error.
Overnight shifts
For a shift such as 22:00 to 06:30, enable the overnight option. The result remains eight hours after a 30 minute break.
Overtime limits
Overtime is optional because legal rules differ. Enter only the thresholds and multipliers that match your contract or internal policy.

Work hours FAQ
How do I calculate my worked hours?
Enter a start time, end time and unpaid break. The calculator subtracts the break from the gross shift duration.
How do I subtract a lunch break?
Enter the lunch break in minutes on the same day. A 09:00-17:30 shift with 30 minutes break gives 8 h 00.
How do I calculate a day that ends after midnight?
Use the overnight checkbox for that period so the end time is treated as the following day.
How do I convert hours and minutes to decimal hours?
Divide the minutes by 60. For example, 7 h 30 equals 7.5 decimal hours.
How do I calculate overtime?
Enable overtime and enter your own daily or weekly threshold. The calculator does not assume a universal legal threshold.
Can I enter multiple breaks?
This version accepts one unpaid break total per day and multiple work periods. More detailed break intervals can be added later without changing the engine.
Can I calculate two weeks of work?
Yes. Choose the two-week mode to display fourteen rows and calculate each week separately for weekly overtime.
How does rounding work?
Choose no rounding or a 5, 6, 10 or 15 minute increment, then apply it to each period or to the daily total.
Can the result be used directly for payroll?
Use it as a check only. Payroll rules, records and approvals depend on your employer and local law.
Are my times sent to a server?
No. The calculation runs in your browser, and local saving uses browser storage.
Can I print or export my timesheet?
Yes. You can copy a summary, print the result or export the table as CSV.
What is the difference between gross and net time?
Gross time is the full shift duration before breaks. Net time is the worked duration after unpaid breaks.
