This calculator provides an estimate of worked hours and optional pay based on the values you enter. It does not replace payroll, tax, financial, or labor law advice.
What is a work hours calculator?
It estimates daily and weekly work time from your start, end, and break entries.
How to use a timesheet calculator
Enter the start time, end time, and break for any day you worked, then review the estimated total hours and optional pay.
How breaks affect total work time
Break minutes are subtracted from the daily shift length, so longer breaks reduce the estimated worked hours.
When this calculator is useful
Use it for simple timesheets, weekly planning, overnight shifts, or a quick estimate before moving numbers into another system.
Practical guidance
What this tool does
This tool estimates daily and weekly work hours from start times, end times and break minutes. If you add an hourly rate, it can also show a simple pay estimate based on the calculated hours.
When to use it
Use it to check a timesheet, compare shifts, plan weekly hours or estimate pay from an hourly rate.
Example use
For example, enter 09:00 to 17:30 Monday to Friday with a 30 minute break each day. The calculator estimates 8 worked hours per day, 40 hours for the week and optional pay if you enter an hourly rate.
How this tool works
For each completed day, the calculator measures the time between start and end, treats an earlier end time as an overnight shift, subtracts break minutes and adds the result to the weekly total. Optional pay is estimated by multiplying total hours by the hourly rate.
Limitations
It is not a payroll system and does not apply legal overtime, rounding rules, paid break policies, time-clock approvals, taxes or employer-specific settings. It is not payroll, HR, legal, tax or financial advice.
Privacy note
The tool does not require an account and the entered form data is processed in your browser for the core timesheet output.

FAQ
How do I calculate work hours with breaks?
Calculate the shift length from start to end, then subtract the break minutes. This tool does that estimate automatically.
Can this calculator handle overnight shifts?
Yes. If the end time is earlier than the start time, the tool treats the shift as crossing midnight.
Can I calculate weekly hours?
Yes. The calculator adds the estimated hours from every filled day to show a weekly total.
Is this a payroll tool?
No. It provides an estimate based on your own input and does not replace payroll or legal systems.
