Frequently Asked Questions
How do I calculate overtime?
Standard overtime in the US is time worked beyond 40 hours per week, paid at 1.5× the regular rate. Some states also require daily overtime (beyond 8 hours/day). Use our calculator to sum daily hours, then identify the weekly total.
How do I handle lunch breaks in time calculations?
Subtract the break duration from total time worked. Example: Worked 8 AM to 5 PM (9 hours) with a 30-minute unpaid lunch = 8.5 hours paid time. Our calculator allows you to enter and subtract break time.
