How overtime is counted
Regular hours are the first 40 in the week. Overtime is anything above 40, paid at 1.5× if you enter an hourly rate. That is the federal FLSA weekly baseline, not your state's full wage-and-hour code.
regular = min(week, 40 hours) overtime = max(0, week − 40 hours) decimal hours = minutes ÷ 60 gross estimate = regular × rate + overtime × rate × 1.5
Worked example
Five 8-hour weekdays → 40:00 regular, 0:00 overtime. Add Saturday 4 hours → 4:00 overtime. At $20/hour that is $800 regular + $120 overtime = $920 gross estimate, before taxes.

FAQ
When does overtime start?
After 40 hours in the workweek, at 1.5×. That matches the federal FLSA weekly baseline for most non-exempt employees in the US. Some employers and some states (including California daily overtime) use different rules. Those are not in this version.
How do I enter hours?
A week total as decimal hours (45, 45.5) or h:mm
(45:30). Suffixes: 45h, 45h 30m,
90m. Or switch to by-day.
Is this 50-state overtime law?
No. Not 50-state legal advice. FLSA weekly baseline only. Daily OT, seventh-day, double time, union contracts, and salaried exemptions are not applied.
Is this official payroll?
No. An estimate of hours and, if you enter a rate, gross pay. It does not withhold tax. Check your employer's timekeeping and your pay stub.
This overtime calculator is an estimate, not legal advice, not payroll, and not 50-state wage-and-hour compliance. It uses the federal FLSA weekly baseline only: hours over 40 in a workweek at 1.5×. Your employer, contract, or state may differ. Confirm before you submit a timesheet or pay anyone.
