How weekly hours are estimated
Enter decimal hours for Monday through Sunday. The calculator adds them, treats hours up to the entered threshold as regular, and shows hours above that threshold separately.
The threshold starts at 40 hours but can be changed as a planning input. This does not decide overtime eligibility. Actual treatment can depend on the employer workweek, hours actually worked, exemptions, agreements, and location-specific rules.
Decimal totals are rounded to two places for display. The hours-and-minutes conversion rounds the combined total to the nearest minute.
Example weekly hours calculation
If you work 8 hours Monday through Friday, total weekly hours are 40 and overtime is 0.
If you work 9 hours Monday through Friday, total weekly hours are 45 and overtime after 40 is 5 hours.
Weekly decimal hours versus clock times
Use this page when you already know each day's decimal hours. Use the time card calculator when you need to subtract breaks from clock-in and clock-out times, or the work hours calculator for one shift.
Official workweek reference
Federal guidance describes a fixed, recurring seven-day workweek and a common overtime framework for covered non-exempt employees. The calculator's editable threshold is an estimate input and does not replace state, local, industry, or employee-specific rules.
