Hook
Ever felt like you spend most of the week working for the government and the last day for yourself? This calculator shows you exactly how many days — and it hurts.
Key Numbers
- Median full-time wage ~$82k → effective rate ~24% → ~1.2 days a week to the ATO before any other tax
- Backbench federal MP on ~$233,660 → effective rate ~32% before expense allowances
- PM on ~$607,516 → effective rate ~37% (but with parliamentary pension worth millions over a lifetime)
- HECS, Medicare levy, MLS, LITO all modelled — GST, fuel excise, rego, council rates deliberately NOT modelled (your real rate is higher)
Context
The calculator uses published 2025–26 ATO rates for resident individuals. Enter what lands in your bank (net), or what's on the payslip (gross), in any period. It runs a binary-search solver to reverse the piecewise tax function so either input gives you the same honest answer.
The "days a week" visual converts your effective rate into a 5-day working week. At a 24% effective rate, you're effectively working Monday until ~lunchtime Tuesday for the Commonwealth; the rest is yours — before every other layer of indirect tax kicks in.
Takeaway
You are not imagining it. The Australian tax system is dense, layered, and designed so that the true burden on a wage earner is invisible. This calculator makes the income-tax layer visible. The other layers — GST, fuel, alcohol, stamp duty — are documented in the adjacent Australian Tax Guide and are the reason your real effective rate is higher still.

- Australia's top marginal rate (45% + 2% Medicare) is one of the highest in the OECD, while the top bracket starts at $190,000 — lower than in most comparable economies.
- Fuel excise, GST, alcohol excise, tobacco excise, stamp duty, council rates, rego, and dozens of smaller charges are not in this calculator — your real 'effective rate' is meaningfully higher.
- Employer super (12% from 1 July 2025) is legally your money but is locked away until preservation age — it does not land in your bank account this year.
- LITO (Low Income Tax Offset) phases out by ~$66,667. Above that income, every extra dollar earned is taxed at at least 32% marginal (30% income tax + 2% Medicare).
- The average full-time wage (~$98k) falls well inside the 30% bracket. The 'middle class' in Australia is taxed at 30c+ in the dollar at the margin.
- Federal backbench MPs earn ~$233,660 base + allowances. The Prime Minister's salary package is ~$607,000 — over 6× the average full-time wage.
