Overtime and Penalty Rates Calculator
Your pay for overtime, weekends and public holidays, and how much you keep after tax.
This week you earn $1,488 before tax. The extra hours add $158, or about $107 after tax.
Common award rates are filled in. Check your award or agreement and change them if yours differ.
Each extra hour is paid at your base rate times its multiplier (150% is 1.5x). The tax on the extra is worked out as if you earned this much every week: the extra yearly income tax and Medicare levy, divided by 52. Your payslip may withhold a little more or less in a single week, and it evens out at tax time. Overtime doesn't earn super under most awards, so super isn't included.

Common overtime and penalty rates
Your award or enterprise agreement sets your rates, and they vary a lot between industries. Common ones are:
- Overtime: 150% (time and a half) for the first two or three hours, then 200% (double time).
- Saturday: 125% to 150%.
- Sunday: 150% to 200%.
- Public holidays: 225% to 250%.
Why overtime seems to be taxed more
Overtime isn't taxed at a special rate. It's added to your pay, so the extra is taxed at your top (marginal) rate, and in a big week your employer may withhold more than usual. If you've had too much withheld over the year, you get it back when you lodge your tax return.
