Frequently asked questions

Are these calculators free to use?

Yes, every PropRadar calculator is free and requires no sign-up. Calculations run entirely in your browser. We don't save or track your inputs.

How accurate is the rental yield calculator?

The rental yield calculator uses standard Australian formulas: gross yield = (weekly rent x 52) / price, net yield subtracts your estimated operating expenses, and cashflow subtracts mortgage interest. Accuracy depends entirely on your inputs, so use realistic expense estimates (1.5-2.5% of property value annually covers most properties) and a current mortgage rate.

Does the stamp duty calculator cover all states?

Yes, the stamp duty calculator covers every Australian state and territory (NSW, VIC, QLD, WA, SA, TAS, ACT, NT) and supports owner-occupier, investor, and first home buyer classifications. 2026-27 rates are used, checked against each state revenue office in September 2026.

How does the borrowing capacity calculator work?

It follows APRA serviceability guidelines: your income, living expenses, and existing debt are assessed at a stress-tested interest rate (current rate + 3% buffer). The result is a realistic estimate, but actual lender policies vary; pre-approval from a broker or lender is the only definitive answer.

Can I use these calculators without creating an account?

Yes. The calculators are fully public and don't require a login. If you want to apply the same maths to 110,000+ active Australian listings with pre-calculated scores, you can register for the main platform free.
