Introduction
Australia's property market is characterised by high prices in major cities, Lenders Mortgage Insurance above 80% LVR, and state-based stamp duty regimes that vary significantly from NSW to QLD. Government schemes like the 5% Deposit Scheme (formerly the First Home Guarantee) have helped some buyers enter the market with just a 5% deposit and no LMI. These calculators help Australian buyers navigate every step of the purchase process.
Key Calculators
- Home Loan Repayment Calculator — Standard principal and interest repayments over 25 or 30 years. Australian mortgages compound monthly. Use this to compare variable vs fixed rate periods: Open the Home Loan Repayment Calculator
- LVR and LMI Calculator — Lenders Mortgage Insurance is required when LVR exceeds 80% (i.e., deposit less than 20%). LMI can add a significant cost to your loan depending on LVR and loan size: Open the LVR and LMI Calculator
- 5% Deposit Scheme Calculator — Under the Australian Government's 5% Deposit Scheme (formerly the Home Guarantee Scheme), eligible first-home buyers can buy with a deposit as low as 5% and no LMI. Property price caps apply by location: Open the 5% Deposit Scheme Calculator
- Stamp Duty Calculator — Stamp duty varies significantly by state and territory, and each has its own concessions for first-home buyers and owner-occupiers. Check your state revenue office for current rates: Open the Stamp Duty Calculator

Tips for Australian Homebuyers
Always get pre-approval before making an offer — Australian auctions are unconditional, and cooling-off periods are short or non-existent in some states. Factor stamp duty into your savings target early, because on a typical home it can run to tens of thousands of dollars. If you're close to the 20% LVR threshold, consider saving a little longer to avoid LMI. The 5% Deposit Scheme is excellent if you qualify; property price caps apply by location, so check the current caps on the government's first home buyer website.
