How to use the overtime pay calculator
- Enter your Hourly rate.
- Enter your Regular hours for the period, such as 40 for a week.
- Enter the Overtime hours. Halves such as 2.5 are accepted.
- Choose the Overtime multiplier: 1.5× (time and a half), 2× (double time), 1.25×, or Other to type a Custom multiplier.
- Choose the Currency and read Total pay, Regular pay, Overtime pay, Overtime hourly rate and Effective hourly rate.
What it does and when to use it
Overtime often makes a payslip hard to check. This calculator splits the pay so you can see exactly what the extra hours earned, then compare it with what your employer paid. It is also useful before agreeing to a long week: you can see whether the extra pay is worth the time.
The multiplier depends on where you work and on your contract. In the US, the Department of Labor states that employees covered by the Fair Labor Standards Act must get at least time and one-half for hours over 40 in a workweek. Many contracts elsewhere use 1.5× or 2×, and some use 1.25×. The calculator offers all three, plus any other figure.
To see what your usual hours add up to over a year, the hourly to annual salary calculator does the conversion. To estimate what reaches your bank after deductions, use the take-home pay calculator, or the UK take-home pay calculator for UK tax and National Insurance.
How it works
- Regular pay = hourly rate × regular hours
- Overtime hourly rate = hourly rate × multiplier
- Overtime pay = hourly rate × overtime hours × multiplier
- Total pay = regular pay + overtime pay
- Effective hourly rate = total pay ÷ (regular hours + overtime hours)
The calculator does not decide which hours count as overtime; you enter them. It also treats your base hourly rate as the “regular rate”. If your employer folds other payments into that rate, your payslip can differ from this simple model.
Worked examples
