How the calculator works
The calculator follows two people from the same starting point:
- The buyer pays the deposit and costs to buy, mostly stamp duty, then the loan, council rates, insurance and repairs. When they sell, they keep the home’s value minus the loan left and the costs of selling.
- The renter invests the deposit and costs to buy instead, and pays rent.
Each month, whoever pays less invests the difference, so both spend the same. The result is who has more after the years you choose.
Example
An $800,000 home with a $160,000 deposit, at 6.2% over 30 years, against rent of $700 a week:
| Amount | |
|---|---|
| Owning, first month | $4,953 |
| Loan repayment | $3,920 |
| After 7 years | Renting ahead by about $68,000 |
| Buying pays off after | 22 years |
Home price growth changes everything: at 5% a year instead of 3%, buying comes out ahead by about $64,000 after 7 years, and pays off after 4.
What matters most
- Home price growth: small changes make a big difference over time.
- How long you stay: stamp duty takes years to earn back.
- Your interest rate: at higher rates, more of each repayment is interest you don’t get back.
