LMI Calculator Guide (Australia)
Lenders Mortgage Insurance (LMI) is typically charged when your deposit is under 20% (LVR above ~80%). It protects the lender — not you.
When LMI usually applies
- Deposit < 20%
- Certain lender policy tiers (80–85–90–95% LVR)
- Some borrowers may have different thresholds depending on risk settings
How to estimate LMI on MoneyWiseCalc
- Tool: Home Loan Repayment Calculator
- Enter property value + deposit
- The calculator estimates LVR and shows an LMI estimate (where enabled)
How to reduce or avoid LMI
- Increase deposit (even small increases can move you to a better LVR tier)
- Use a guarantor (family pledge) — if available and appropriate
- Consider eligible schemes that can avoid LMI with lower deposits (where applicable)
Key caution
Actual LMI varies significantly by lender/insurer and borrower profile. Treat it as an estimate, then confirm with the lender.
