We have compared the most popular free property calculators in Australia to help you find the right tool for your situation.
1. LookingToSell — Moving Costs Calculator
Best for: Complete cost picture (buying + selling)
The LookingToSell Moving Costs Calculator is Australia's most comprehensive all-in-one property cost calculator. It covers 25+ individual cost items in a single report, including agent commissions, stamp duty, conveyancing, legal fees, inspection costs, mortgage costs, and moving expenses.
- Covers: Agent fees, stamp duty, conveyancing, LMI, inspections, moving costs, and more

2. State Revenue Office Calculators — Stamp Duty

Each state revenue office provides its own stamp duty calculator. These are the authoritative source for exact stamp duty amounts, as they use the current legislated rates and thresholds.

Our Recommendation

For official stamp duty figures, cross-check with your state revenue office. For mortgage-specific calculations, bank calculators and comparison sites are useful supplements.
