Where the calculator rules come from
PayCalculator.online uses its own calculation code, but the rules should be traceable. These are the main official sources used to check tax, withholding, HELP, Medicare and super settings. Sources were last checked on 8 September 2026.
PAYG withholding tax tables
Payroll withholding can differ from final annual tax. The ATO tax tables explain the formulas employers use during the year.
Check the Australian Taxation Office sourceHELP repayment thresholds and rates
Study-loan estimates are versioned by financial year and checked against the ATO's published repayment settings.
Check the Australian Taxation Office sourceSuper guarantee rate
Employer super is shown separately from take-home pay and uses the rate for the selected period.
Check the Australian Taxation Office sourceMedicare levy
The standard levy and supported low-income treatment are kept separate from the Medicare levy surcharge, which this calculator does not estimate.
Check the Australian Taxation Office sourceTax residency
Tax residency can change which rates apply. A visa, citizenship or current address does not decide tax residency on its own.
Check the Australian Taxation Office sourceWhat the site does with those rules
The calculator converts your entered pay to an annual amount, separates super where required, applies the selected financial-year rules, then shows the result in annual, monthly, fortnightly and weekly views. It does not copy an ATO calculator or connect to your payroll record.
