- •Leave Saturday/Sunday blank if you did not work those days.
- •The standard US overtime threshold is 40 hours per week at 1.5x pay.

How to Use This Calculator
Enter start and end times for each day of the week in 24-hour format (HH:MM). Add break times in minutes. Set your hourly rate, overtime threshold, and overtime multiplier. The calculator totals weekly hours and computes pay including overtime.
Understanding the Formula
Daily Hours = (End Time - Start Time) - Break. Weekly Total = sum of daily hours. Regular Pay = min(Total, Threshold) x Rate. Overtime Pay = max(0, Total - Threshold) x Rate x Multiplier. Total Pay = Regular + Overtime.
Examples
Standard 40-hour work week
5 days, 9:00-17:00, 30 min break each day = 7.5 hours/day x 5 = 37.5 hours. At $25/hr = $937.50.
Week with overtime
5 days at 8.5 hours + Saturday 6 hours = 48.5 hours. Regular: 40 hrs x $25 = $1,000. Overtime: 8.5 hrs x $37.50 = $318.75. Total: $1,318.75.
Frequently Asked Questions
What is the standard overtime rate?
In the United States, the Fair Labor Standards Act (FLSA) requires overtime pay of 1.5 times the regular rate for hours worked beyond 40 in a workweek for non-exempt employees.
How are overnight shifts handled?
If the end time is before the start time (e.g. start 22:00, end 06:00), the calculator automatically adds 24 hours to compute the correct duration.
Assumptions & Limitations
- Based on the Gregorian calendar; does not handle historical calendar systems.
- Leap years are accounted for in all date calculations.
- Overtime is calculated on a weekly basis; daily overtime rules vary by jurisdiction and are not applied here.
