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
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
| Hours Worked | Regular Pay | Overtime Pay | Total 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.
