Weekly Overtime Hours Calculator
Use a weekly total and weekly threshold to separate regular hours from hours above that threshold. This is a time split only, so it does not assume a country, overtime premium, or legal exemption status.
Weekly time split only. It does not decide which hours are legally compensable or overtime, calculate pay, combine daily and weekly rules, or determine employee exemptions. Confirm the applicable weekly threshold with official guidance, your contract, and payroll records.

How this estimate works
- Regular hours are the lower of total hours and the entered threshold.
- Hours above the threshold are total hours minus the threshold, never below zero.
- Both inputs cover the same week; do not enter a monthly total against a weekly threshold.
Official working-hours context
- Japan MHLW: working-hours guidance
- U.S. Department of Labor: overtime-pay requirements and workweek context
The calculator deliberately asks you for the threshold because overtime rules, covered hours, and exceptions vary by jurisdiction and worker.
Frequently asked questions
What weekly threshold should I enter?
Enter the regular-hours limit that applies to the same week as your total. Check official rules, your contract, and payroll policy.
Does this calculate overtime pay?
No. It only splits hours. Pay rates and premium categories require a separate calculator and the correct legal classification.
