How do I calculate hours worked?
For each day, subtract the clock-in time from the clock-out time, then subtract any unpaid break. Add the days together for the weekly total. For example, 8:30 AM to 5:15 PM is 8 hours 45 minutes; minus a 30-minute lunch that is 8 hours 15 minutes, or 8.25 hours in decimal.

A work hours calculator and timesheet calculator in one
Use it as a work hours calculator for a single shift: fill in one day and read the hours worked straight away. Fill in the whole week and it works as a timesheet calculator, with daily totals, the weekly total, overtime and pay, ready to print or export for payroll. The same page covers hours worked for hourly staff, freelancers billing clients and anyone checking a payslip.
How do I convert minutes to decimal hours?
Payroll usually wants hours as a decimal number. Divide the minutes by 60: 15 minutes is 0.25 hours, 30 minutes is 0.5 and 45 minutes is 0.75. So 7 hours 45 minutes is 7.75 hours. The calculator shows both forms for every day and the week.
| Minutes | Decimal | Minutes | Decimal |
|---|---|---|---|
| 5 | 0.08 | 35 | 0.58 |
| 10 | 0.17 | 40 | 0.67 |
| 15 | 0.25 | 45 | 0.75 |
| 20 | 0.33 | 50 | 0.83 |
| 25 | 0.42 | 55 | 0.92 |
| 30 | 0.50 | 60 | 1.00 |
How is overtime calculated?
The calculator offers the most common rules. After 40 hours a week is the general rule for many hourly workers in the United States. After 8 hours a day counts every hour past 8 on a single day. Both counts daily overtime first and then any regular hours past 40 in the week, without counting an hour twice. Overtime hours are paid at the rate multiplier you set, 1.5× by default.
Rules differ by country, state, industry and contract: some places pay double time after 12 hours, add rest-day rules or count weeks differently. Use the result as a check and follow the rules that apply to your job.
What about night shifts?
If the clock-out time is earlier than the clock-in time, the calculator treats it as the next morning. A shift from 10:00 PM to 6:30 AM with a 30-minute break counts as 8 hours, on the day the shift started.
