30% of $300,000.00 is $90,000.00.
Quick answer
30% of $300,000 is $90,000. That's a property deposit comfortably clear of the 20% mark most Australian lenders use to decide whether to charge Lenders Mortgage Insurance (LMI) — $30,000 more than the $60,000 needed to avoid LMI altogether, giving the buyer a lower loan-to-value ratio and more room to negotiate.

The same formula applies to any percentage question: result = base × (percent ÷ 100). Here, $300,000 ×
(30 ÷ 100) = $90,000. Most Australian lenders use a 20% deposit as the threshold for waiving
Lenders Mortgage Insurance (LMI) — $60,000
on a $300,000 property — so a 30% deposit clears that mark with $30,000 to spare, which can also mean a lower
loan-to-value ratio and access to more competitive interest rates.
Worked example
Zoe has been saving steadily while renting in Bunbury, Western Australia, and has found a renovated three-bedroom house listed at $300,000. Rather than stop saving right at the 20% LMI threshold, she’s decided to keep going a little longer to build in a buffer. The calculation: $300,000 × 30% = $90,000. That’s $30,000 more than the $60,000 a 20% deposit would need, but it leaves Zoe with a smaller $210,000 loan, a lower loan-to-value ratio, and one less thing to negotiate with her lender when she applies.

What is 30% of $300,000?
30% of $300,000 is $90,000. Multiply $300,000 by 0.30, or by 3 then divide by 10, to get the same answer.

20% of $300,000 is $60,000, so a 30% deposit of $90,000 is $30,000 more — comfortably clear of the point where Lenders Mortgage Insurance (LMI) would normally apply.
Does a bigger-than-20% deposit have any benefit beyond avoiding LMI?
Yes — a lower loan-to-value ratio (the loan as a percentage of the property price) can help you qualify for a more competitive interest rate with some lenders, on top of avoiding LMI.
What would a standard 20% deposit be on the same $300,000 property?
A 20% deposit on $300,000 is $60,000 — $30,000 less than the 30% figure — and it's the minimum most lenders need to waive LMI.
Is $300,000 a realistic property price in Australia?
It depends on location — regional centres and more affordable regional cities can still have properties around this price, though it's below the median in most capital cities.
