Free financial calculators for Australia. Home loan, tax, superannuation, and investment calculators with Australia-specific rates and rules.
This page brings together free calculators built around the Australian financial system — home loans, Superannuation, Stamp Duty, HECS-HELP, and tax. Every calculator uses Australian dollars and local terminology, so the results reflect how borrowing, saving, and tax actually work in Australia.
Australia's tax year runs from 1 July to 30 June, with income tax administered by the ATO. Retirement savings are built through Superannuation ("super"), and home buyers need to budget for Stamp Duty and may need Lenders Mortgage Insurance (LMI) if their deposit is below 20%. University graduates often repay a HECS-HELP loan through the tax system. The Reserve Bank of Australia (RBA) sets the cash rate that influences home loan rates (example rates used in our calculators are for illustration only — actual rates vary by lender and change frequently).
The Home Loan Calculator estimates your repayments, and the Borrowing Power Calculator gives an idea of how much you might be able to borrow. The Stamp Duty Calculator and LMI Calculator help with upfront purchase costs, while the Superannuation Calculator projects your retirement balance.
