Common LVR Mistakes (and a Better Way)

Updated 14 July 2026 · Property and home loans

A LVR Calculator gives a fast answer, but the answer is only as good as what goes in. These are the mistakes we see most often with LVR calculations in Australia, and how to avoid them.

1. Comparing headline rates only

Fees, offset accounts and flexibility on extra repayments can matter as much as the rate.

2. Assuming prices always rise

Property growth varies by location and period. Plan for flat or falling prices too.

3. Borrowing the maximum

Lenders test you at a higher rate, but your budget still needs room for rate rises, repairs and life changes.

4. Forgetting purchase costs

Stamp duty, conveyancing, inspections and moving can add several percent to the price.

5. Overlooking the detail that matters most here

Lenders use their own valuation, which can be lower than the price you pay, pushing your LVR up.

How the LVR changes with loan amount

A common mistake is getting one input slightly wrong. Here is what happens to the LVR when “Loan amount ($)” is off by up to 20% in either direction, with everything else held steady.

Loan amount ($)	LVR
480,000	68.57%
540,000	77.14%
600,000	85.71%
660,000	94.29%
720,000	102.86%

At 480,000 the result is 68.57%; at 720,000 it is 102.86%. If a small change in this input moves the answer a lot, it is worth double-checking that figure before you rely on the result.

A quick sense check

LVR = loan ÷ property value × 100. With typical inputs the calculator returns LVR of 85.71%. If your own result looks wildly different, check that each figure is in the right unit and period (weekly, monthly or yearly) before drawing conclusions.
