How overtime is calculated
Overtime hours are usually the hours worked above 40 in a single workweek. They are paid at the "premium" rate, most commonly 1.5× the regular hourly rate (time and a half). Some states and contracts also use 2× (double time) once daily or weekly thresholds are reached.
The formula every calculator in this hub uses is: Overtime pay = OT hours × Regular rate × Multiplier. Gross pay for the period is regular hours × rate plus overtime pay.
Federal vs state overtime
The federal FLSA sets a floor: 1.5× after 40 weekly hours for non-exempt workers. States can be more generous. California, for example, also requires 1.5× after 8 daily hours and 2× after 12. Local minimum wage and prevailing wage rules can further shift the regular rate. This hub does not encode state-specific rules; always confirm your jurisdiction.
Common overtime mistakes
- Using daily overtime in a state that only uses weekly overtime, or vice versa.
- Forgetting to include shift differentials or non-discretionary bonuses in the regular rate.
- Treating salaried employees as automatically exempt without checking the FLSA duties test.
- Mixing 12-hour AM/PM times instead of 24-hour HH:MM when entering shifts.
