Free Australian Tax and Money Calculators

What Is AusToolKit?
AusToolKit is a small set of free Australian financial calculators, built to answer one specific question at a time — what will I actually take home, how much tax will I pay, how much super am I accruing — without wading through a government website or handing over an email address. Every calculator uses current ATO rates and thresholds for the 2026–27 financial year, kept up to date as rates change.
Who These Calculators Are For
Anyone comparing job offers who wants to know what a salary actually means after tax. Anyone buying a property who wants to know what stamp duty will cost before they make an offer. Sole traders and small businesses working out GST on an invoice. Employees checking whether their payslip and their HECS-HELP repayment look right. None of it requires an account, and nothing you type into a calculator is ever sent anywhere or stored — it all runs in your browser.
How Our Calculators Work
Each calculator is built from the same published rates the ATO and state revenue offices use — income tax brackets, the Medicare levy and surcharge, HELP repayment thresholds, the super guarantee rate and contribution caps, GST, and every state and territory's stamp duty schedule. Every number a calculator produces is shown with a plain-language explanation of how it was worked out below the tool, so you're never just staring at an unexplained figure. See every current rate in one place on our tax rates page, or browse our guides for deeper explanations of how Australian tax, super and property duty actually work.
