How to use it
- Type the Hourly rate, then the Hours worked in the period you are checking.
- Enter the Regular hours before overtime from your contract or your country's rule, for the same period as the hours.
- Set the Overtime multiplier, such as 1.5, and read Gross pay for the period and How it is worked out.
How overtime is calculated
Hours up to the threshold are regular hours and are paid at the hourly rate. Hours above the threshold are overtime and are paid at the hourly rate times the multiplier. The two parts add up to the gross pay for the period.
Regular pay = hourly rate × regular hours (the smaller of hours worked and the threshold)
Overtime hours = hours worked − threshold (never less than 0)
Overtime pay = hourly rate × multiplier × overtime hours
Gross pay = regular pay + overtime payWhere the threshold and the multiplier come from
The International Labour Organization states that overtime is paid at a higher rate than normal hours, and that an overtime policy should follow national law and collective agreements. The exact threshold and multiplier are therefore set by the law of the country where you work and by your contract, not by one fixed figure for everyone.
What this calculator does not include
- Tax, social contributions and other deductions. All figures are gross.
- Night, weekend or public holiday premiums, which some rules add on top of the overtime rate.
- Overtime given as time off instead of money. Enter those hours in the period if you want to see their value.
Worked example: 20 an hour, 46 hours, threshold 40, multiplier 1.5
Forty hours are regular: 40 × 20 = 800.00. The six hours above the threshold are overtime: 6 × 20 × 1.5 = 180.00. The gross pay for the period is 800.00 + 180.00 = 980.00.
| Part | Hours | Pay |
|---|---|---|
| Regular | 40 | 800.00 |
| Overtime | 6 | 180.00 |
| Gross pay | 980.00 |
Frequently asked questions
How much is one hour of overtime?
It is the hourly rate multiplied by the overtime multiplier. At 20 an hour and a multiplier of 1.5, each overtime hour pays 30. Multiply that by the overtime hours in the period to get the overtime pay.
Is time and a half always 1.5 times the rate?
Time and a half is a multiplier of 1.5 on the hourly rate. It is common, but a contract or a country's rule can set a different figure, so enter the one that applies to you.
Do I count overtime hours per week or per month?
Count them over the period your law or your contract uses, and use the same period for the hours worked and the threshold. If the threshold is a weekly limit, enter the hours worked in that week.
Does the threshold change my pay if I work fewer hours?
No. Hours below the threshold are paid at the normal hourly rate and no overtime is added. The regular and overtime parts only change once the hours go above the threshold.
Why is my payslip different from this result?
Payslips include allowances, night or weekend premiums, tax and social contributions, and an employer may round or pay overtime in another way. Treat this result as an estimate of the gross pay.
