How to use the timesheet calculator
This timesheet calculator adds up one week: type your start and end time for each day you worked, and your unpaid break in minutes. The Hours column fills in as you type, and an empty day counts as zero. The week starts filled in with 9:00 to 17:30 and a 30-minute break, Monday to Friday.
- Enter start and end times in 24-hour or 12-hour format, whichever your browser shows.
- Enter the break in minutes: 30, 45, 60.
- Read the total in hours and minutes (40:00) and in decimal hours (40.00).
- Enter your hourly rate to get gross pay before tax.
Employers can use it as an employee time tracking calculator, one person’s week at a time. For a team that works at computers, employee time tracking records everyone’s hours without anyone typing them in.
A worked example
Here is a part-time week with uneven days and one late shift. The calculator gives the same numbers when you type them in.
| Day | Start | End | Break | Hours |
|---|---|---|---|---|
| Mon | 08:30 | 17:15 | 45 min | 8:00 |
| Tue | 09:00 | 13:00 | 0 min | 4:00 |
| Wed | 12:00 | 20:30 | 30 min | 8:00 |
| Thu | 22:00 | 06:00 | 30 min | 7:30 |
| Fri | 09:00 | 15:15 | 30 min | 5:45 |
| Total | 33:15 |
33 hours 15 minutes is 33.25 decimal hours. At $22 an hour, that is $731.50 gross pay.
Hours and minutes or decimal hours?
Use decimal hours for pay and invoices, and hours and minutes for reading a schedule. They are the same amount of time written two ways: 33:15 means 33 hours and 15 minutes, which is 33.25 hours. Multiplying 33.15 by your rate instead would underpay you.
| Minutes | Decimal |
|---|---|
| 15 | 0.25 |
| 20 | 0.33 |
| 30 | 0.50 |
| 40 | 0.67 |
| 45 | 0.75 |
What about overtime?
This calculator uses one hourly rate for all hours. In the US, the Fair Labor Standards Act requires time and a half for non-exempt employees after 40 hours in a workweek (U.S. Department of Labor, as of October 2026). Some states add daily overtime rules. This is not legal advice: check your state’s rules and your contract.
Stop adding up hours by hand
A calculator needs you to remember when you started and stopped. TimeUno records the time you spend at your computer on its own, files it under your projects and builds the timesheet from it at the end of the week. You edit the lines and export the timesheet as CSV. It works on computer work only: shifts away from a computer still need a calculator or a timesheet template.

Questions people ask
How do I calculate hours worked with a lunch break?
Subtract the start time from the end time, then subtract the unpaid break. 8:30 to 17:15 is 8 hours 45 minutes; take off a 45-minute lunch and you worked 8 hours.
How do I turn hours and minutes into decimal hours?
Divide the minutes by 60 and add them to the hours. 7:45 is 7 + 45/60 = 7.75 hours. Payroll and invoices use the decimal figure, so multiply that by your rate.
Does the calculator work for night shifts?
Yes. If the end time is earlier than the start time, it counts the shift as running past midnight. 22:00 to 06:00 with a 30-minute break is 7 hours 30 minutes.
Does it calculate overtime?
No. It adds up your hours and multiplies them by one rate. To check overtime, look at the weekly total and pay the hours above your threshold at the higher rate yourself.
Is there a timesheet calculator app?
This time sheet calculator runs in any web browser, on a computer or a phone, with nothing to install. If you work at a computer, the TimeUno desktop app records your hours on its own, so there is nothing to type in. TimeUno has no mobile app.
Is my data saved or sent anywhere?
No. The calculator runs in your browser and nothing you type leaves the page. Reset puts the default week back.
