How it works
Repayments use the standard amortising loan formula for principal & interest at a fixed rate. The monthly payment is calculated so that the loan is fully paid off over the chosen term.
LVR (Loan-to-Value Ratio) is your loan amount divided by the property price. Lenders typically require LMI (Lenders Mortgage Insurance) when LVR is above 80%.
Total interest is the difference between everything you pay and the original loan amount. Lower rates, shorter terms and extra repayments all reduce total interest.

Frequently asked questions
- How are repayments calculated?
- Using the standard amortising P&I formula: M = P·r / (1 − (1+r)^−n), where r is the monthly rate and n is the number of months.
- What does LVR mean?
- Loan-to-Value Ratio — your loan amount as a percentage of the property value. Lenders usually require LMI above 80%.
- Why does total interest change so much with term?
- A longer term lowers each repayment but you pay interest for more years, so the total interest grows substantially.
- Is this a real loan quote?
- No — this is an estimate based on the inputs you provide. Lenders consider income, expenses, credit history and other factors.
