Quick answer
20% of $900,000 is $180,000. That's the deposit size Australian lenders typically require before waiving Lenders Mortgage Insurance (LMI) on a home loan. For a buyer in a higher-end coastal market like Byron Bay, reaching this threshold means avoiding a substantial LMI premium, though it takes considerably longer to save than a smaller deposit.

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 $900,000 × (20 ÷ 100) = $180,000. Twenty percent is
the deposit threshold Australian lenders typically use: below it, lenders usually charge
Lenders Mortgage Insurance (LMI) to
cover their risk, and on a higher-value property that premium can be substantial, so buyers in this price
bracket have extra incentive to reach the full 20% before applying.
Worked example
Isla and her partner are buying a beachside property in Byron Bay, on the NSW North Coast, listed at $900,000. With prices this high, they know that skipping a 20% deposit would mean a very large LMI premium on top of an already sizeable loan, so they’ve spent an extra year saving to clear the threshold. The calculation: $900,000 × 20% = $180,000. That’s the deposit they need before settlement, leaving a $720,000 loan. It’s twice the $90,000 a 10% deposit would require, but reaching the full 20% means their lender won’t charge LMI at all — a saving that, on a property this expensive, easily runs into tens of thousands of dollars.
Frequently asked questions
What is 20% of $900,000?
20% of $900,000 is $180,000. You get this by multiplying $900,000 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 20% deposit on a $900,000 property, that's $900,000 × 0.20 = $180,000.
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. On a higher-value property like a $900,000 home, LMI can add tens of thousands of dollars, so avoiding it by saving the full 20% is often worth the extra time.
How much would a 5% deposit be on the same $900,000 property?
A 5% deposit on $900,000 is $45,000 — a quarter of the size of the 20% deposit — but it would typically mean paying a substantial LMI premium unless you qualify for a low-deposit guarantee scheme.
What's 10% of $900,000, for comparison?
10% of $900,000 is $90,000 — exactly half of the $180,000 needed for a full 20% deposit.
