Estimate regular pay and overtime pay separately
The overtime calculator separates regular hours from overtime hours and applies the selected overtime multiplier. It can help employees review a pay estimate and help employers model labor cost before approving additional hours.
Formula
Worked example
At a $20 regular hourly rate with 5 overtime hours paid at a 1.5 multiplier, estimated overtime pay is $150. Add regular gross pay for the same pay period to estimate total gross earnings before deductions.
The correct overtime rule depends on the worker and jurisdiction
Overtime eligibility, thresholds, workweek definitions, exemptions, multiple-rate rules, and required multipliers vary. A daily threshold may apply in one place while a weekly threshold applies in another.
Use the calculator only after identifying the rule that applies to the employment relationship. Pay statements, employment agreements, official labor guidance, and payroll records provide the inputs; the calculator performs the arithmetic.
Match hours and rates to the same pay period
Separate regular and overtime hours before entering them. Do not count the same hour in both groups, and do not combine two workweeks when the applicable rule requires a weekly calculation.
Bonuses, commissions, shift differentials, tips, multiple rates, paid leave, and deductions can affect payroll calculations. When these apply, a simple base-rate estimate may not match the final pay statement.
Check these details before calculating
- Confirm the applicable overtime threshold and multiplier.
- Use gross hourly pay and the correct workweek or pay period.
- Keep regular and overtime hours mutually exclusive.
- Compare the estimate with the employer's documented payroll calculation.
