Overtime Calculator

Where Overtime Pay Actually Kicks In

Overtime pay isn't a flat bonus — it's calculated hour by hour once a threshold is crossed, and the rate applied to those extra hours depends on the multiplier your employer or jurisdiction uses. This calculator splits a week's hours into regular and overtime portions and prices each separately, so the total reflects exactly how the hours broke down.

The Formula

Regular Pay = min(Hours Worked, Threshold) × Hourly Rate
Overtime Pay = max(0, Hours Worked − Threshold) × Hourly Rate × Multiplier

The default threshold is 40 hours and the default multiplier is 1.5× (standard "time-and-a-half" under U.S. federal law for non-exempt employees), but both are adjustable for different overtime rules or double-time scenarios.

A Worked Example

Weekly pay at $20/hour, 40-hour threshold, 1.5x overtime multiplier
Hours WorkedRegular PayOvertime PayTotal Pay
35$700.00$0.00$700.00
40$800.00$0.00$800.00
45$800.00$150.00$950.00
50$800.00$300.00$1,100.00
60$800.00$600.00$1,400.00

Every hour past 40 is worth 1.5x the base rate here — at $20/hour that's $30/hour for overtime, which is why the total climbs faster once the threshold is crossed.

Where This Matters

  • Verifying a paycheck — checking that overtime hours were paid at the correct multiplier against the hours actually logged.
  • Shift planning — managers estimating labor cost before scheduling extra hours, since overtime hours cost 50% more than regular hours at the standard multiplier.
  • Negotiating a different multiplier — some union contracts or holiday-shift rules use 2x (double time) instead of 1.5x; adjusting the multiplier shows the cost difference directly.
