Quick answer
20% of $450,000 is $90,000. That's the deposit size Australian lenders typically require before waiving Lenders Mortgage Insurance (LMI) on a home loan. For a buyer eyeing a $450,000 property in a regional centre like Bathurst, reaching this threshold means avoiding the LMI premium altogether, though it takes longer to save than a smaller deposit.

Browse MathsHow it works
To find a percentage of a number, multiply the number by the percentage and divide by 100:
result = base × (percent ÷ 100). For this page, that’s $450,000 × (20 ÷ 100) = $90,000. Twenty percent is
the deposit threshold Australian lenders typically use: below it, lenders usually charge
Lenders Mortgage Insurance (LMI) to
cover their risk, so buyers face a trade-off between buying sooner with a smaller deposit and paying LMI, or
saving longer for the full 20% to avoid the premium altogether.
Worked example
Liam has been renting in Bathurst, in the NSW Central West, and has found a three-bedroom house on the edge of town listed at $450,000. Rather than buy sooner with a 10% deposit and pay LMI on top, he’s chosen to keep saving until he reaches the full 20% threshold. The calculation: $450,000 × 20% = $90,000. That’s the deposit Liam needs before settlement — a loan of $360,000 once he draws down the mortgage. It’s double the $45,000 a 10% deposit would require, but reaching it means his lender won’t charge LMI at all, saving him a premium that can run into thousands of dollars.
