How to calculate hours worked
- Enter the start time and end time for each day you worked. Type 9, 9:30, 930 or 9.5 — all are read as a time.
- Enter the unpaid break in minutes. Paid breaks stay in the total, so leave them out.
- Read the daily total. The weekly total adds all seven days and shows it in hours:minutes and in decimal hours.
- Add an hourly rate to see gross pay. Turn on overtime if hours over 40 in the week are paid at 1.5×.
Worked example
A shift from 8:30 AM to 5:15 PM with a 45-minute unpaid lunch. 5:15 PM − 8:30 AM is 8 hours 45 minutes. Take off 45 minutes and the shift is 8:00, or 8.00 decimal hours. At $20.00 an hour that is $160.00.
Hours and minutes to decimal
Payroll systems use decimal hours. Divide the minutes by 60 — eight hours and five minutes is the same amount of time as 8.08 hours.
| Minutes | Decimal | Example |
|---|---|---|
| 5 | 0.08 | 8:05 = 8.08 |
| 10 | 0.17 | 8:10 = 8.17 |
| 15 | 0.25 | 8:15 = 8.25 |
| 20 | 0.33 | 8:20 = 8.33 |
| 30 | 0.50 | 8:30 = 8.50 |
| 45 | 0.75 | 8:45 = 8.75 |
| 50 | 0.83 | 8:50 = 8.83 |
Frequently asked questions
How do I count a shift that crosses midnight?
Enter the times as usual. When the end time is earlier than the start time, the calculator treats the end as the next day and shows a note on that row.
Are breaks subtracted automatically?
Only the unpaid minutes you enter in the break column. If your break is paid, leave the column at 0.
What is 7 hours 30 minutes in decimal?
7.50 hours. Divide the minutes by 60: 30 ÷ 60 = 0.50.
Does the calculator round to the nearest quarter hour?
No. Totals are exact to the minute. Employers may round under their own policy, so check your own before comparing a total with a payslip.
Is my timesheet saved?
No. Nothing you type is sent to a server. The Share link puts your entries in the link itself, after the #, so you can bookmark it or send it to yourself.
How is overtime calculated here?
Hours over 40 in the week are multiplied by 1.5× your hourly rate. That is the federal rule under the FLSA; some states and some jobs differ, so check the rule that applies to you.
