Quick answer
20% of $800,000 is $160,000. That's the standard deposit Australian lenders look for before waiving Lenders Mortgage Insurance (LMI) — a smaller deposit gets buyers into a home sooner, but a full 20% deposit on an $800,000 house avoids LMI charges altogether.

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 $800,000 × (20 ÷ 100) = $160,000. 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
Ryan has been renting in Wollongong, New South Wales, for eight years and is finally close to a full deposit on an $800,000 house near the escarpment. His mortgage broker ran the numbers on a smaller deposit, but the LMI premium on an $800,000 loan would have added thousands to his upfront costs. The calculation: $800,000 × 20% = $160,000. That’s the deposit Ryan needs before settlement. It’s four times the $40,000 a 5% deposit would require, but reaching it means his lender won’t charge LMI at all, saving him a one-off premium that can run into thousands of dollars.
Frequently asked questions
What is 20% of $800,000?
20% of $800,000 is $160,000. You get this by multiplying $800,000 by 0.20 (or dividing by 5).
How do I calculate a home deposit percentage?
Multiply the property price by the deposit percentage expressed as a decimal. For a standard 20% deposit on an $800,000 house, that's $800,000 × 0.20 = $160,000.
Why do buyers aim for a 20% deposit specifically?
Most Australian lenders charge Lenders Mortgage Insurance (LMI) on any deposit below 20% of the property price. Saving a full 20% deposit avoids that extra cost entirely, though it takes longer to save.
Is it better to save 20% or buy sooner with a smaller deposit?
It depends on your situation. A smaller deposit gets you into the market sooner but usually means paying LMI (or needing a guarantee scheme), while a 20% deposit avoids LMI entirely but takes longer to save and exposes you to further price growth while you wait.
How much would a 5% deposit be on the same $800,000 house?
A 5% deposit on $800,000 is $40,000 — a quarter of the size of the 20% deposit — but it would typically mean paying LMI unless you qualify for a low-deposit guarantee scheme.
