Loan-to-value ratio (LVR) explained Australia — how to calculate it, the 80% rule, and why it matters when prices move

Loan-to-value ratio (LVR) is how lenders compare what you borrow with what the property is worth. It is expressed as a percentage. It shapes deposit strategy, whether you may pay lenders mortgage insurance (LMI), pricing bands, refinance options, and how exposed you are if values fall.

This guide explains the formula, deposit scenarios, the ~80% rule, valuation versus purchase price, how LVR works when you refinance, and how to stress-test a price move with the free negative equity & LVR what-if calculator. General information only — not personal advice.

Key takeaways

• LVR ≈ loan ÷ property value × 100. Example: $400,000 loan on $500,000 value = 80% LVR.
• Around 80% LVR is the usual threshold where standard LMI starts to apply for many lenders (at 80.01%+). A true 20% deposit on purchase price typically targets 80% LVR and often avoids standard LMI — confirm on your file.
• Lenders assessing a purchase usually take the lower of purchase price or bank valuation.
• When prices fall and the loan balance is unchanged, LVR rises. That can block a clean refinance long before you reach negative equity (LVR above 100%).
• Use the calculator on this page to model +5% to −15% value moves with your balance fixed.

What is loan-to-value ratio (LVR)?

LVR is a risk metric. A lower LVR means more equity relative to the loan — generally less risk for the lender. A higher LVR means you are borrowing a larger share of the property’s value.

LVR ≈ (Loan amount ÷ Property value) × 100

LVR vs LTV: same idea. LVR is standard in Australia and New Zealand; LTV is more common in the US and UK.

How to calculate LVR (worked examples)

At purchase

You buy a home for $600,000 with a $120,000 deposit (20%). Loan = $480,000.

LVR = 480,000 ÷ 600,000 × 100 = 80%.

After you own the home

You owe $720,000. A realistic current value is $900,000.

LVR = 720,000 ÷ 900,000 × 100 = 80%.

If value falls 10% to $810,000 and the balance is still about $720,000:

LVR ≈ 720,000 ÷ 810,000 × 100 ≈ 88.9%.

Same debt — different lending picture. That is why price falls matter for refinance even when repayments are fine.

Free calculator — LVR if prices rise or fall

Use the interactive tool on this page (same engine as the negative equity calculator landing).

Enter estimated value and loan balance, then try presets such as −5%, −7%, −10%. Your contractual repayment stays fixed — prices do not change the instalment by themselves.

Deposit size vs LVR (and LMI)

Illustrative only — on a $600,000 property. LMI rules are lender- and product-specific; government guarantee schemes can change the LMI picture for eligible buyers.

Correction vs common competitor tables: a clean 20% deposit → 80% LVR is generally the band where borrowers avoid standard LMI, not where LMI is “highest risk.” Above 80% is where LMI risk rises. Always confirm with the lender’s policy and your LMI calculator.

Why LVR matters to lenders

• Risk: higher LVR → less equity buffer if forced sale proceeds fall short.
• LMI: many lenders require LMI when LVR exceeds about 80% (protects the lender, not you).
• Pricing: lenders often price in LVR tiers (indicative only — not a quote):
  • Under ~60% — typically strongest pricing band
  • ~60–70% — still competitive
  • ~70–80% — standard owner-occupier band for many products
  • Above ~80% — fewer options; LMI and/or higher pricing common
• Product caps: low-doc / self-employed and some specialist loans are often capped well below 95%.

Purchase price vs bank valuation

For a new purchase, lenders typically calculate LVR using the lower of:

1. The contract purchase price, and
2. The bank valuation

If you agree to pay $800,000 but the valuation comes in at $760,000, the bank may size the loan against $760,000. Your required cash can jump overnight — a valuation shortfall.

Common flashpoints: off-the-plan settlements, thin comps, unique properties, and bidding above recent sales evidence. Brokers can sometimes order upfront valuations across lenders before you are stuck — enquire.

How LVR affects refinancing

On refinance, LVR uses:

Current loan balance ÷ New bank valuation × 100

The original purchase price drops out. Principal paydown and genuine value growth lower LVR; a soft valuation raises it.

Example: balance $780,000, expected value $1,000,000 → 78% LVR. If the valuation is $950,000 → about 82.1% LVR. Nothing changed about your repayment habit — the switch may now involve LMI or fewer lenders.

Practical path: request written retention, then compare term-for-term in the refinance playground. Guide: refinancing service.

LVR when house prices are falling

Cotality’s August 2026 national Home Value Index fell 0.9% (fifth monthly decline), with Sydney 7.1% below its February peak and 93% of capital-city suburbs falling through winter (ABC / Cotality).

The RBA still estimates fewer than 1% of mortgagor households in negative equity (March 2026 FSR). Thin buffers still matter: REA Group analysis reported in trade press found only 87 expanded 5% Deposit Scheme households estimated in negative equity (under 0.2% of ~48,000 purchases since October 2025), yet 48% of that cohort had 5% equity or less (The Adviser / REA).

Action list:

1. Check current balance and a realistic value → LVR
2. Model another 5–10% fall in the calculator
3. Review refinance before you urgently need it
4. Keep a cash buffer — not every dollar must hit the loan
5. Know when negative equity actually bites (sale / refinance / hardship)

How to lower your LVR

• Save a larger deposit or choose a lower purchase price
• Pay down the principal (or use a genuine offset while keeping liquidity)
• Avoid unnecessary redraw / top-ups that push LVR up
• Value-adding renovations only if uplift is credible (avoid overcapitalising)
• In some cases, a guarantor structure can reduce the effective LVR for LMI purposes — complex; needs proper advice

Genuine 100% LVR cash purchases of the security alone are uncommon; guarantor loans use additional security so the bank’s overall position is stronger. Not suitable for everyone.

FAQ

What is a good LVR?

Often 80% or lower for avoiding standard LMI and keeping options open. Lower can help pricing — your income, credit and property still drive the outcome.

What is the maximum LVR?

File-specific. Many full-doc owner-occupiers can reach ~95% with LMI or an eligible government guarantee; other products cap lower.

Will my property always need a full physical valuation?

Not always. Lenders may use AVMs, desktop or kerbside assessments. Full inspections are more common at high LVR, unusual properties or higher risk files.

Does a falling LVR cut my repayment?

No. Repayments follow balance, rate and term — not the index. LVR is a ratio, not a cashflow switch.
