Overtime Hourly Rate Calculator
Calculate an overtime rate from your entered multiplier for entered overtime pay.
How to use Overtime Hourly Rate Calculator
1. Choose Currency for all amounts, then enter Base Hourly Rate, Overtime Multiplier in the labelled units. 2. The multiplier is the total multiple of the base rate, not just the premium. For example, 1.5 includes the base rate plus a 0.5 premium. Zero models no overtime pay. No overtime multiplier or legal entitlement is assumed. The arithmetic excludes tax, deductions, thresholds, time off in lieu and payroll rounding. A zero multiplier models no overtime pay; hours needed requires a positive resulting rate. 3. Select Calculate or press Enter to see the result. 4. Select Select Copy result to copy the answer, or Reset to clear the form.
Why use this tool?
Use Overtime Hourly Rate Calculator to compare your entered entered overtime pay assumptions with a stated formula and a reproducible example.
How the calculation works
Overtime hourly rate = base hourly rate × entered multiplier. The multiplier is the total multiple of the base rate, not just the premium. For example, 1.5 includes the base rate plus a 0.5 premium. Zero models no overtime pay. No overtime multiplier or legal entitlement is assumed. The arithmetic excludes tax, deductions, thresholds, time off in lieu and payroll rounding. A zero multiplier models no overtime pay; hours needed requires a positive resulting rate. Choose one currency for every monetary input. The selector labels and formats amounts; it does not apply an exchange rate. Money displays use the selected currency’s standard minor units, including whole yen for JPY. Exact decimal arithmetic precedes rounding; halfway minor units round away from zero. Numeric input/result magnitudes are bounded by 9,007,199,254,740,991. UK background on contractual overtime arrangements: https://www.gov.uk/overtime-your-rights. The calculator uses entered assumptions and does not determine legal entitlement.
Example
Overtime Shift example: Currency = GBP; Base Hourly Rate = 20; Overtime Multiplier = 1.5. Result: £30.00 per hour.
Practical tip
Enter the multiplier specified for the pay arrangement being modelled. For example, 1.5 means 1.5 times the base rate.
Frequently asked questions
Is 1.5 a required overtime rate?
No. It is a worked example only. Enter the multiplier for the arrangement you are modelling and check the applicable contract and rules separately.
Does changing the currency convert these amounts?
Choose one currency for every monetary input. The selector labels and formats amounts; it does not apply an exchange rate. Money displays use the selected currency’s standard minor units, including whole yen for JPY. Exact decimal arithmetic precedes rounding; halfway minor units round away from zero.
What assumptions should I keep with this result?
