How this calculator works
Australian home loans (mortgages) work on a principal-and-interest repayment structure where your monthly repayment covers both the loan balance and accrued interest. Interest is typically calculated daily based on your outstanding balance.
If your deposit is below 20% of the property value, lenders generally require Lenders Mortgage Insurance (LMI), which protects the lender (not you) and can add thousands to your upfront costs. This calculator focuses on ongoing repayments, but remember to factor LMI into your buying costs.
Your repayment also does not include council rates, strata levies, or building insurance — these are additional ownership costs to budget for separately.
Worked example
An AU$850,000 property with 20% deposit at 6.2%
- 1Monthly rate: 6.2% ÷ 12 = 0.5167%
- 2Months: 30 × 12 = 360
- 3Monthly repayment ≈ AU$4,157/month
- 4Total repaid: AU$4,157 × 360 = AU$1,496,520
- 5Total interest: AU$1,496,520 − AU$680,000 = AU$816,520
