How to calculate hours worked on a time card
For each day, subtract the clock-in time from the clock-out time, then subtract unpaid breaks. Add the days together and convert the minutes to decimal hours for payroll:
- Use a 24-hour clock. 5:00 pm is 17:00, so 8:30 to 5:00 pm is 17:00 − 8:30 = 8 hours 30 minutes.
- Take out unpaid meal breaks. A 30-minute lunch leaves 8:00. Short rest breaks of 5 to 20 minutes are paid time under federal rules and stay in[hw].
- Add up the week. Friday above runs to 6:15 pm, 9:15 after lunch, so the week is 41 hours 15 minutes.
- Convert to decimal. 15 minutes ÷ 60 = 0.25, so 41:15 is 41.25 hours. See the time to decimal calculator for any number of minutes.
- Split off overtime. 40 regular hours plus 1.25 overtime hours, paid at time and a half: at $20 that is $800 + $37.50 = $837.50.
Hour hour calculator: shifts that cross midnight
If the clock-out time is earlier than the clock-in time, the shift ran past midnight, and the calculator adds 24 hours. A 10:00 pm to 6:30 am shift with a 30-minute break is 8 hours. For federal overtime, all hours count toward the workweek in which they are worked; the day the shift started does not matter.
| Shift | Unpaid break | Hours (h:mm) | Decimal hours |
|---|---|---|---|
| 9:00 am – 5:00 pm | 30 min | 7:30 | 7.50 |
| 8:00 am – 5:00 pm | 60 min | 8:00 | 8.00 |
| 7:00 am – 3:30 pm | 30 min | 8:00 | 8.00 |
| 8:30 am – 6:15 pm | 30 min | 9:15 | 9.25 |
| 6:00 am – 6:00 pm | 30 min | 11:30 | 11.50 |
| 10:00 pm – 6:30 am | 30 min | 8:00 | 8.00 |
| 3:00 pm – 11:45 pm | 15 min | 8:30 | 8.50 |
Rounding, breaks and what counts as work
Employers may round punch times to the nearest 5 minutes, tenth of an hour or quarter hour, as long as rounding averages out so employees are paid for all time actually worked[hw]. Time spent waiting on duty, required training and short breaks is generally hours worked; a bona fide meal period of 30 minutes or more, when you are fully relieved of duty, is not[fs22].
- Quarter-hour rounding: 7 minutes or less rounds down, 8 or more rounds up (8:07 becomes 8:00, 8:08 becomes 8:15).
- Tenth-hour rounding uses 6-minute blocks: 0.1 hour = 6 minutes.
- Daily overtime: a few states pay overtime after 8 hours in a day. This calculator applies the federal weekly rule; enter a different threshold if your state or contract differs.
Once you have the hours, the time and a half calculator prices the overtime and the weekly paycheck calculator shows what is left after taxes. If you earn paid time off per hour worked, the weekly total is what drives your accrual in the PTO calculator.
Frequently asked questions
How do I calculate hours worked between two times?
Convert both times to a 24-hour clock, subtract the start from the end, and subtract unpaid breaks. 7:45 am to 4:15 pm is 16:15 − 7:45 = 8 hours 30 minutes; minus a 30-minute lunch, 8 hours.
Is lunch counted on a time card?
Under federal rules a meal break of 30 minutes or more when you are completely relieved of duty is unpaid. Breaks of 5 to 20 minutes are paid and should not be deducted.
What is the best free time card calculator for payroll?
One that handles pm times and overnight shifts, subtracts unpaid breaks, shows decimal hours and splits overtime over 40. This one does all five and runs in your browser without an account.
How do I turn time card minutes into decimal hours?
Divide the minutes by 60: 15 minutes is 0.25, 30 is 0.5, 45 is 0.75. 38 hours 20 minutes is 38.33 hours.
