Hours Worked Calculator
Turn clock-in and clock-out times into accurate daily and weekly hours. Subtract unpaid breaks, see decimal hours for payroll, and spot overtime automatically.
Calculate Your Weekly Hours
Enter a clock-in and clock-out time for each day, plus any unpaid break, and the calculator will work out your total hours worked for the week — including a decimal figure ready for payroll and any overtime owed.
How the Calculation Works
Five steps behind every result on the right
Record Clock-In and Clock-Out Times
Enter the exact start and finish time for each shift. The calculator handles overnight shifts that cross midnight automatically.
Subtract Unpaid Breaks
Add any unpaid lunch or rest break in minutes. This is deducted from the shift length before the day’s total is calculated.
Convert to Decimal Hours
Leftover minutes are converted to decimal format automatically — for example 30 minutes becomes 0.5 — so figures drop straight into payroll software.
Total the Week
Every day you fill in is added together to give a single weekly hours figure, shown alongside your daily breakdown.
Apply Your Overtime Threshold
Set the number of hours per week that count as standard time. Anything above that line is separated out as overtime.

Minutes to Decimal Hours
Use this table to convert common minute values into the decimal hours most payroll systems expect.
| Minutes | Decimal Hours | Example Shift | Decimal Total |
|---|---|---|---|
| 15 minutes | 0.25 hrs | 8h 15m | 8.25 |
| 30 minutes | 0.5 hrs | 7h 30m | 7.50 |
| 45 minutes | 0.75 hrs | 6h 45m | 6.75 |
| 20 minutes | 0.33 hrs | 9h 20m | 9.33 |
| 10 minutes | 0.17 hrs | 5h 10m | 5.17 |
| 50 minutes | 0.83 hrs | 4h 50m | 4.83 |
Hours Worked FAQ
Answers to the most frequently asked questions about calculating hours worked.
Subtract the clock-in time from the clock-out time to get the total shift length, then subtract any unpaid breaks. The result is the number of hours actually worked, which can be converted to decimal format for payroll.
Divide the number of minutes by 60. For example, 30 minutes is 0.5 hours, 15 minutes is 0.25 hours, and 45 minutes is 0.75 hours. Most payroll systems require decimal hours rather than hours and minutes.
No, unpaid breaks such as a lunch hour should be subtracted from the total shift length before calculating pay. Paid breaks, such as short rest breaks in many workplaces, are typically still counted as hours worked.
This depends on your contract and local employment law, but a common threshold is 40 hours in a single week. Hours worked beyond that threshold are often paid at a higher overtime rate, commonly time-and-a-half.
