- Uses the multiplier you enter; verify it against your award or agreement.
Frequently asked questions
How is one extra shift taxed?
The shift income is added to estimated annual income. The calculator measures the increase in annual tax, Medicare levy and optional HELP.
Why can my payslip withholding be different?
Payroll schedules annualise each pay period and may withhold differently from this final-year estimate.
Does “worth it” include childcare or travel?
No. Subtract your own shift-specific childcare, travel, parking or meal costs from the displayed net value.
