Lenders Mortgage Insurance (LMI) & LVR Breakdown
What is Lenders Mortgage Insurance (LMI) & How Does It Work?
In Australia, Lenders Mortgage Insurance (LMI) is a one-off insurance premium charged by mortgage lenders whenever a borrower has a cash deposit of less than 20% of the property purchase price—meaning their Loan-to-Value Ratio (LVR) exceeds 80%.
LMI protects the bank, not the borrower. If a borrower defaults on their home loan repayments and the property is sold for less than the outstanding mortgage balance, LMI covers the bank's financial loss.
LVR Scale Tiers & Premium Scale Comparison Matrix
LMI premiums increase steeply as your LVR rises above 80%:
| LVR Range | Typical Premium % | Est. LMI on $600k Loan | Lender Risk Level |
|---|---|---|---|
| Up to 80.00% LVR | 0.00% (No LMI) | $0 | Standard Risk |
| 80.01% – 85.00% LVR | 1.20% – 1.60% | $7,200 – $9,600 | Low Risk Tier |
| 85.01% – 90.00% LVR | 2.40% – 3.20% | $14,400 – $19,200 | Moderate Risk Tier |
| 90.01% – 95.00% LVR | 4.20% – 5.80% | $25,200 – $34,800 | High Risk Tier |
First Home Guarantee Scheme: Buy with 5% Deposit & 0% LMI
Under the Australian Federal Government's First Home Guarantee (FHBG) scheme, eligible first home buyers can purchase a property with a deposit as low as 5% without paying any LMI.
Housing Australia acts as a government guarantor for up to 15% of the property value, enabling eligible buyers to save tens of thousands of dollars in LMI fees.
Capitalized LMI vs Upfront Cash Payment
Most Australian banks allow borrowers to capitalize LMI into their home loan. This means adding the LMI premium directly to your loan balance.
While capitalizing LMI reduces upfront settlement costs, it increases your total monthly mortgage repayments and results in paying interest on the LMI premium over the 30-year loan term.
How to Calculate LMI: 5 Steps
Follow these standard steps when calculating Lenders Mortgage Insurance.
- 1
Determine Total Property Price & Cash Deposit
Input your target property valuation and net cash deposit available.
- 2
Calculate Loan-to-Value Ratio (LVR)
Divide your required loan principal by the property purchase price.
- 3
Apply Insurer Premium Scale & Tax Rates
Match your LVR to Genworth or QBE rate scales including 10% GST and state insurance duty.
- 4
Evaluate Capitalized vs Upfront Payment
Decide whether to pay LMI in cash at settlement or capitalize it into your mortgage.
- 5
Check First Home Guarantee Eligibility
Verify if you qualify for government 5% deposit schemes to eliminate LMI entirely.
LMI Provider & Home Loan Approval Checklist
Gather these essential records when applying for home loans with LVR above 80%.

Provide bank statements showing at least 5% genuine savings held for 3 months.
LMI Provider Underwriting Application
Complete Helia (Genworth) or QBE insurance proposal forms via your lender.

Common LMI Calculation Errors & Refinancing Pitfalls
Avoid these frequent mistakes when navigating Lenders Mortgage Insurance.
Confusing Lenders Mortgage Insurance (LMI) with Mortgage Protection Insurance
LMI covers the bank against loan default; it does not protect the borrower if they lose their job or experience illness.
Borrowing slightly above an LVR threshold bracket
Crossing from 89.9% LVR into 90.1% LVR can double the LMI premium rate tier, costing thousands extra.
Forgetting that interest is charged on capitalized LMI
Adding a $15,000 LMI premium to a 30-year loan at 6.25% interest adds over $17,000 in extra interest over the loan term.
Refinancing too early without considering unrecoverable LMI
Refinancing an 88% LVR loan after 12 months requires paying a brand new LMI premium with the new lender.

Frequently Asked Questions (FAQ)
What is Lenders Mortgage Insurance (LMI)?
Lenders Mortgage Insurance (LMI) is a one-off insurance premium protecting the bank or mortgage lender in the event that you default on your home loan and the property proceeds fail to cover the remaining debt balance.
Does Lenders Mortgage Insurance protect the borrower?
No. Despite being paid for by the borrower, LMI exclusively protects the lender. It does not provide any coverage or financial protection for the homebuyer.
How can I avoid paying LMI in Australia?
You can avoid LMI by saving a deposit of at least 20% (LVR <= 80%), securing a guarantor loan using a family member’s equity, qualifying for the federal First Home Guarantee scheme (5% deposit, 0% LMI), or working in select professional categories (e.g. doctors, lawyers) eligible for LMI waivers.
What does it mean to capitalize LMI into a home loan?
Capitalizing LMI means adding the total insurance premium directly onto your total mortgage principal balance rather than paying it upfront in cash. While it reduces upfront settlement costs, you pay interest on the LMI balance over your loan term.
Is LMI refundable when refinancing a home loan?
In most cases, LMI is non-refundable and non-transferable. If you refinance to another lender within 1 to 2 years, some insurers offer partial partial-year refunds, but after 2 years, LMI is generally non-refundable.
