What the result means

LVR is the loan divided by the lender’s valuation. Equity is the rest. A fall in prices raises LVR even if you never borrow more.

How it is calculated

LVR = loan ÷ value × 100. Equity = value − loan
  • Value: Lender valuation or purchase price if you do not have a valuation.

If the loan exceeds the value, equity is negative in this simple picture.

Assumptions

  • Estimates only — not tax, legal, credit or financial advice. Check the official source or your contract before relying on a figure.
  • One loan against one property.

Worked example

$680,000 loan on $850,000

Purchase with 20% deposit.

LVR
680,000 / 850,000 = 80%
Equity
$170,000

That is the usual 80% LVR example used in the mortgage calculator defaults.

Valuation is not always the contract price

Lenders may value below what you agreed to pay. Use their figure if you have it. LMI, rate pricing and some products step at 80%, 90% and similar bands.

Questions

Does this include a second mortgage?

Add both loans together before you enter the loan amount if they are secured on the same property.
