What Are Money & Finance Calculators?
Money and finance calculators help simplify common financial calculations by applying formulas automatically. Instead of manually working through loan repayments, interest, tax, savings or investment calculations, you can enter the relevant values and receive an estimate instantly.
Easy Calculator’s Australian finance tools cover several areas of personal finance, including home loans, credit, Australian taxation, salary calculations, superannuation, savings and investing.
Australian Home Loan & Mortgage Calculators
Buying or refinancing a home can involve several different calculations. A mortgage repayment calculator can estimate regular principal and interest repayments, while an extra repayment calculator can demonstrate how additional payments may change the loan term and total interest.
Other property-related financial calculations include borrowing power, stamp duty and loan-to-value ratios. These tools can be useful during the early stages of researching a property purchase, but lender calculations, fees and eligibility requirements can vary.
Australian Tax & GST Calculators
Australian workers and businesses often need to perform tax-related calculations. Our finance collection includes tools for estimating PAYG income tax, converting salary amounts and calculating Australian Goods and Services Tax (GST).
The Australia GST Calculator allows you to add or remove the standard 10% GST from a fully taxable amount. The detailed GST calculator page also explains how inclusive and exclusive GST amounts are calculated.
Where a calculator relates specifically to Australian tax, property or financial rules, check the calculator’s notes, assumptions and applicable period before relying on the result.
Savings & Compound Interest Calculators
Savings calculators can help illustrate how regular deposits, interest rates and time affect a savings balance. Compound interest means that interest can be earned not only on the original balance but also on previously accumulated interest.
For investment planning, return calculators can provide projections based on assumptions entered by the user. Actual investment returns can be higher or lower and may be affected by fees, taxation, inflation and market conditions.
