Frequently asked questions
What is a property investment calculator?
A property investment calculator is a free online tool that lets Australian investors quickly model the financial outcome of a property purchase — including rental yield, mortgage repayments, stamp duty, cash flow and ROI. Our calculators are designed specifically for Australian markets, regulations and currency.
How do property calculators work in Australia?
Each calculator runs a specific formula on the numbers you enter. A yield calculator divides annual rent by purchase price. A mortgage calculator runs the standard amortisation formula on your loan amount, rate and term. A stamp duty calculator applies your state's progressive duty schedule. The full investment property calculator combines all of these into one analysis, plus DCF, NPV and IRR.
Are these property investment tools free?
Yes. Every calculator on Property Forecast Pro is free, requires no signup, and runs entirely in your browser. There are no paywalls and no usage caps.
Do these mortgage calculators Australia work for all states?
Yes. All calculators use Australian dollars and Australian assumptions. The Stamp Duty Calculator supports NSW, VIC, QLD, WA, SA, TAS, ACT and NT, including first home buyer concessions.
