Australia Mortgage Calculator — Frequently Asked Questions

What is LMI and when do I need to pay it in Australia?
Lenders Mortgage Insurance (LMI) is required when your deposit is less than 20% of the property value. It protects the lender, not you, if you default. LMI costs range from 1% to 4% of the loan amount and can be added to your loan balance. Avoiding LMI by saving a 20% deposit saves thousands of dollars.
How is stamp duty calculated in Australia?
Stamp duty varies by state and territory — each has its own rates and thresholds. For example, in NSW stamp duty for a $800,000 home is approximately $31,000, while in Victoria it's around $43,000. First-home buyers may qualify for full or partial exemptions depending on the property value. Our calculator includes stamp duty estimates.
What is an offset account and how does it save me money?
An offset account is a transaction account linked to your mortgage. The balance in the offset account is deducted from your loan principal before interest is calculated, effectively earning the mortgage interest rate tax-free on your savings. For example, $50,000 in an offset account on a $500,000 loan means you only pay interest on $450,000.
What is the difference between principal and interest vs interest-only loans?
Principal and interest (P&I) loans pay down both the loan amount and interest each month, building equity over time. Interest-only loans only cover interest costs for a set period, typically 1 to 5 years, keeping monthly payments lower but not reducing the loan balance. Interest-only is more common for investment properties.
What is the lender assessment rate in Australia?
Lenders assess your ability to repay at a higher rate than your actual loan rate — typically 3% above the current rate. This is similar to a stress test and ensures you can afford higher payments if interest rates rise. The Australian Prudential Regulation Authority (APRA) sets guidelines for these assessment buffers.
