Shift and penalty-rate estimate
Estimate time-and-a-half, double time, weekend pay, public holiday pay and casual loading from an hourly rate. Use it for planning, not award compliance.

This page estimates pay from a known hourly rate and multiplier. It does not decide which award, classification, allowance or penalty rate applies. That boundary matters because award compliance is legal/payroll risk, not generic calculator math.
For minimum award rates and conditions, use the Fair Work Pay and Conditions Tool. For after-tax salary estimates, use the Australian Salary Calculator.
Weekly overtime gross = base hourly rate x multiplier x overtime hours. Annual overtime gross = weekly overtime gross x weeks worked. The after-tax impact compares your ordinary annual pay with your annual pay including repeated overtime.
Worked example: $35 per hour at 1.5x for 5 overtime hours gives $262.50 gross overtime per week, or $13,650 per year if repeated for 52 weeks. Against ordinary annual pay of $69,160, the calculator estimates about $4,368 extra annual tax and about $9,282 net overtime before HELP.
This page does not decide whether 1.5x, 2x, weekend or public-holiday rates apply. Use Fair Work or your award/agreement for that legal question.
Use the multiplier from your award, enterprise agreement or employment contract. The calculator provides common examples only.
No. Casual loading compensates for casual employment conditions. Overtime and penalty rates depend on the applicable award or agreement.
