About the Hours Calculator
This hours calculator is a simple weekly time card. Type the start and end time of every shift from Sunday to Saturday and it adds up daily hours, the weekly total and your average day. Overnight shifts that run past midnight and split shifts with two blocks in one day are handled too.
Choose your overtime rules – after 40 hours a week, after 8 hours a day, or both – set a multiplier such as 1.5 and your hourly rate, and you get regular pay, overtime pay and gross weekly pay. Everything is saved only in this browser, so your card is still here next time.
How to use
- For each day, enter clock in, clock out and the unpaid break in minutes. Leave days off blank.
- Same schedule every day? Fill in Monday and tap Copy Mon → Tue–Fri.
- For a split shift, tap + Shift 2 and enter the second start and end time.
- Check the overtime rules, multiplier and hourly rate to see overtime hours and gross pay.
- Use Copy summary to paste your hours into an email or spreadsheet, or Print the time card.
How hours are calculated
- Daily hours = (clock out − clock in) + second shift − break.
- If clock-out is earlier than clock-in, 24 hours are added (overnight shift). Example: 10:00 PM to 6:00 AM with a 30-minute break = 7:30.
- Decimal hours = minutes ÷ 60. Payroll uses decimal hours × hourly rate.
| Minutes | Decimal | Minutes | Decimal |
|---|---|---|---|
| 5 | 0.08 | 30 | 0.50 |
| 10 | 0.17 | 40 | 0.67 |
| 15 | 0.25 | 45 | 0.75 |
| 20 | 0.33 | 50 | 0.83 |
How overtime is counted
With the weekly rule on, regular hours above the weekly limit (e.g. 40) become overtime, assigned to the last days of the week. With the daily rule on, hours above the daily limit (e.g. 8) on any day are overtime. When both are on, daily overtime hours are left out of the weekly total so nothing is counted twice.
Example: four 8-hour days plus a 9.5-hour Friday = 41.5 hours. With a 40-hour weekly rule, 1.5 hours are overtime. At $20/h and 1.5×: $800.00 regular + $45.00 overtime = $845.00.
Rules differ by state, country, industry and contract (some places use daily overtime, double time or a different weekly limit). The calculator applies exactly the rules you set and is not legal advice.
FAQ
How do I convert hours and minutes to decimal?
Divide the minutes by 60 and add them to the hours. 7 hours 45 minutes = 7 + 45 ÷ 60 = 7.75 hours. The calculator shows both formats for every day and for the week.
Does it work for night shifts?
Yes. When the end time is earlier than the start time, the shift is treated as ending the next morning. 11:00 PM to 7:00 AM is 8 hours, recorded on the day the shift started.
Is the pay before or after taxes?
It is gross pay: hours × rate, plus overtime at your multiplier. Taxes, tips, shift differentials and deductions are not included.
