A worked example
Sarah is buying her first apartment in Melbourne for $650,000. She's saved a $90,000 deposit and needs to borrow $560,000. To calculate her LVR:
Loan amount ÷ property value × 100 = LVR
$560,000 ÷ $650,000 × 100 = 86.15%
Sarah's LVR is 86.15%, which is above the 80% threshold. This means she'll need to pay Lenders Mortgage Insurance (LMI). Her lender quotes her $18,400 for LMI, which she can either pay upfront or add to her loan.
If Sarah had waited another six months and saved an extra $40,000 for a total deposit of $130,000, her loan would be $520,000. That gives an LVR of 80%, just scraping in under the LMI threshold and saving her nearly $20,000. She decides to rent for another six months and build her deposit further.
State-by-state differences
The LVR calculation itself is identical across all Australian states and territories. The property value divided by the loan amount doesn't change whether you're in Sydney or Darwin. However, a few state-specific factors affect your overall borrowing picture:
- NSW: Stamp duty is calculated on the full property value before considering any first home buyer exemptions. Higher property prices mean you need a bigger deposit to hit the same LVR, even if the percentage feels the same.
- VIC: Similar stamp duty considerations. First home buyers can access the First Home Owner Grant for new builds under $750,000, which effectively increases your deposit and lowers your LVR.
- QLD: The First Home Concession can reduce or eliminate stamp duty on properties under $550,000, freeing up more cash for your deposit.
- WA: First home buyers can get a stamp duty exemption on properties up to $430,000 and reduced duty up to $530,000.
- SA, TAS, ACT, NT: Each has different first home buyer schemes and stamp duty thresholds. More money saved on stamp duty means more available for deposit, which directly lowers your LVR.
Common mistakes people make
- Forgetting about upfront costs: People calculate their deposit based on all their savings, then realise stamp duty, conveyancing, building inspections and moving costs eat into that amount. If you've got $100,000 saved and $15,000 goes to stamp duty and fees, your actual deposit is $85,000. Your LVR is higher than you thought, possibly triggering LMI when you planned to avoid it.
- Assuming 80% is a hard cutoff: Some lenders will lend at 85% or even 90% LVR, and some will go to 95% for first home buyers. The LMI cost rises sharply as your LVR increases, but the option exists. Others wrongly think they need a full 20% deposit when they could buy sooner with LMI.
- Not recalculating after property price changes: You get pre-approved based on a $600,000 purchase with $120,000 deposit (80% LVR). Then you find a place for $650,000. Your $120,000 deposit is now only 18.5%, giving you an LVR of 81.5%. You're suddenly paying LMI when you thought you'd avoided it.
- Ignoring genuine savings requirements: Lenders want to see you've saved most of your deposit yourself over three to six months. A $50,000 gift from parents helps your LVR calculation, but the bank might still treat your 'genuine savings' as lower, affecting loan approval regardless of the LVR number.
What this calculator doesn't account for
This calculator gives you a simple LVR percentage, but it doesn't factor in several important aspects of your actual borrowing capacity. It won't tell you whether the lender considers your deposit 'genuine savings' or whether gifted money will be accepted. It doesn't calculate the specific LMI premium you'll pay, which varies between lenders and mortgage insurers. The calculator can't assess your borrowing power based on income, existing debts, living expenses or credit history. It won't account for whether you're buying as an owner-occupier or investor (lenders often have different LVR limits for investment properties). If you're buying off-the-plan, construction loans, or properties in regional areas some lenders consider higher risk, your allowable LVR might be lower than the calculator suggests. It also doesn't factor in capitalised LMI (adding the premium to your loan amount, which increases your effective LVR).
Edge cases and nuances
- Guarantor loans: If your parents use equity in their home as security, you might borrow 100% of the property value with no LMI. The LVR calculator shows a scary number, but the actual loan structure is more complex. The combined security (your property plus the guarantor property) determines the real risk, not your property's LVR alone.
- Buying with equity from another property: You own a $700,000 home with a $300,000 mortgage ($400,000 equity). You want to buy a $500,000 investment property. The calculator shows 100% LVR if you borrow the full $500,000, but lenders assess your total loan-to-value ratio across both properties. Your combined LVR is $800,000 ÷ $1,200,000 = 66.7%, so no LMI applies.
- Low-doc and self-employed borrowers: Even if your LVR is 75%, lenders often cap self-employed and low-doc loans at 80% LVR maximum, and some require 70% to avoid LMI entirely. The LVR number is the same, but the eligibility rules are stricter.
- Unit and apartment restrictions: Some lenders treat apartments above 50 square metres differently to smaller studios. Others limit LVR to 70% or 80% in specific postcodes they consider oversupplied. Your calculated 82% LVR might be acceptable for a house but rejected for a unit in the same suburb.
