Why we built this site
Most Australians make their biggest money decisions with a mix of bank calculators, forum threads and guesswork. Bank calculators are built to sell a product. Forum answers are often out of date by the next 1 July. We built AUFinanceCalculators.com to give you the plain maths behind stamp duty, take-home pay, super, HECS-HELP and home loans, using the rules that actually apply in Australia this financial year.
Every calculator is free, needs no sign-up and runs in your own browser. You get the number, the working behind it and links to the official source, so you can check it yourself.
How we keep the numbers right
Built from official rules
Rates and thresholds come from the ATO, APRA, the RBA, Moneysmart and each state and territory revenue office, never from other calculator sites.
Checked every financial year
Tax brackets, super caps, HELP thresholds and duty tiers are re-checked when they change, usually at 1 July and after each Federal or state Budget.
Transparent assumptions
Each tool lists the assumptions it uses so you can see what it does and does not cover.
