How this calculator works
Loan-to-value ratio (LVR) is one of the most important numbers in Australian home lending. It's simply your loan amount expressed as a percentage of the property's value:
LVR = (loan amount ÷ property value) × 100
The complement of your LVR is your deposit percentage (on a purchase) or equity percentage (on a refinance) โ the two always add up to 100%. 80% LVR is the single most important threshold in Australia: at or below it, you generally avoid Lenders Mortgage Insurance; above it, LMI is generally required, up to around 95% LVR, close to most lenders' standard maximum. This calculator shows your exact LVR, your deposit/equity figures, and the tier your result falls into.
Worked example
Say you're buying a property valued at $700,000 with a $560,000 loan. Your LVR is exactly 80% ($560,000 รท $700,000), meaning your deposit makes up the remaining 20%, or $140,000 โ right at the LMI threshold, so no Lenders Mortgage Insurance is required. By contrast, a $630,000 loan on the same $700,000 property gives a 90% LVR, with a $70,000 (10%) deposit โ comfortably within standard lending limits, but requiring LMI since it's above 80%.
What affects your result
- Deposit size โ the biggest lever on a purchase; crossing 80% LVR specifically avoids Lenders Mortgage Insurance entirely.
- Property valuation โ on a refinance, your LVR depends on the lender's current valuation of your property, not necessarily what you paid for it.
- Loan balance paid down โ every principal repayment reduces your loan amount and therefore your LVR over time, gradually moving you toward or below the 80% threshold even without extra repayments.
- Extra repayments โ a lump-sum or extra monthly repayment can be a deliberate strategy to cross the 80% threshold ahead of a refinance or to remove the need for LMI.
A note on accuracy
The LVR tiers shown reflect commonly-referenced Australian lending thresholds (60/80/90/95%), not a specific lender's pricing criteria, which can vary. This calculator does not factor in valuation fees, application fees, or a lender's specific risk appetite. For guidance on LVR and LMI, see Moneysmart โ Lenders Mortgage Insurance.
