How to use the overtime pay calculator
The formulas
Hourly rate from salary = annual salary ÷ (contracted hours per week × 52)
Overtime at 1.5× = hourly rate × 1.5 × overtime hours
Overtime at 2× = hourly rate × 2 × overtime hours
Gross pay = regular pay + 1.5× pay + 2× pay
Know your own rules
Overtime entitlement is set by law, contract, and local agreements, and they vary widely: US federal law (the FLSA) sets a 1.5× floor after 40 hours a week for covered non-exempt employees, while UK staff rely on their contracts since there is no general statutory rate. Enter the hours in each band according to your rules and this calculator does the arithmetic — it does not decide your entitlement.
Example
On $20/hour: 40 regular hours = $800. Add 6 hours at 1.5× ($30/h) = $180 and 2 hours at 2× ($40/h) = $80, and gross pay for the period is $1,060, of which $260 is overtime.
Frequently asked questions
How is overtime pay calculated?
Multiply your normal hourly rate by the overtime multiplier, then by the overtime hours. At time-and-a-half the rate is 1.5 times normal pay; at double time it is 2 times. This calculator adds both bands plus your regular pay.
How do I get an hourly rate from an annual salary?
Divide the salary by your contracted weekly hours and by 52 weeks. A $41,600 salary on 40 hours a week works out to exactly $20.00 an hour. Choose "Annual salary" and the calculator does this for you.
Does everyone get 1.5x or 2x for overtime?
No. Overtime rules differ by country, employer, contract, and collective agreement. In the US, the FLSA generally requires at least 1.5x after 40 hours in a week for covered non-exempt staff; the UK has no general statutory overtime rate, so it depends on your contract. Always check your own terms — this tool simply applies the multipliers you choose.
Is the result my take-home pay?
No. It is gross pay for the period, before tax, pension, and any other deductions.
