What is the Overtime Pay Calculator?

Overtime should be the easy part of a payslip, but between the base rate, the multiplier and the split of regular versus overtime hours, it's easy to under-count what you're owed. This calculator lays it out: regular pay, the overtime rate, overtime pay and the combined total.

It runs in your browser and updates instantly as you adjust the numbers.

What does this tool do?

You enter your regular hourly rate, your regular hours, your overtime hours and the overtime multiplier — time-and-a-half, double time, or a custom value. It calculates your regular pay, your boosted overtime hourly rate, the overtime pay and your total gross pay for the period.

Preset buttons cover the common multipliers so you don't have to remember the decimals.

Tips

Confirm your multiplier with your contract or local law — time-and-a-half (1.5×) is common but not universal.
Only count hours actually paid at the overtime rate as overtime hours; keep the rest as regular.
Some places pay overtime only past a weekly threshold — split your hours at that threshold.
These are gross figures; your take-home will be lower after tax.
Double-check whether overtime is calculated on your base rate or an adjusted one at your workplace.

Common mistakes to avoid

Using the wrong multiplier

Fix: Check your contract — 1.5× is common, but double time or other rates may apply.

Counting all hours as overtime

Fix: Only the hours paid at the boosted rate are overtime; the rest are regular.

Forgetting the weekly threshold

Fix: If overtime only starts past a set weekly total, split your hours there.

Expecting take-home

Fix: The totals are gross, before tax and deductions.
