Australian Home Loan Repayment Calculator
A $600,000 home loan at 6.0% over 30 years costs about $3,597 a month. Switching to fortnightly repayments cuts roughly four years off the loan and saves around $150,000 in interest.
Prefilled with the Reserve Bank of Australia — Statistical Table F6 Housing Lending Rates of 6.06%, 2026-06-01. Your quoted rate depends on credit score, down payment, loan type and location.
Fortnightly repayments do more than they look like they should
Paying half your monthly amount every fortnight means 26 half-payments a year — the equivalent of thirteen monthly payments instead of twelve. That extra month goes almost entirely to principal. Switch the frequency above to see it.
How your payment is worked out
Your payment is fixed so the loan reaches zero at the end of the term. Early payments are mostly interest because interest is charged on a bigger balance. As the balance falls, more of each payment goes to principal. The chart above shows exactly where that flips for your loan.
What this doesn't include
This is principal and interest only unless you fill in the optional fields. Your actual monthly cost will also include property tax, homeowners insurance, and — if your down payment is under 20% — private mortgage insurance. All three vary by state and lender.
Why our number may differ from your bank's
Usually one of three things: your bank is bundling tax and insurance into the figure, it's adding its own fees, or it's using a different compounding convention. Ours is published on the methodology page, with worked examples you can check.
Frequently asked questions
Is this free?
Yes. No account, no email, no quote request. The site is supported by advertising.
How accurate is it?
The maths is exact for the figures you enter. We test every formula against worked examples published by the relevant central bank or regulator, and those tests are on the methodology page. What we can't know is your lender's specific fees, so treat the result as principal and interest unless you've filled in the optional fields.
Where do the interest rates come from?
Each country page prefills a reference rate from an official source — a central bank or national statistics body — and shows the source and publication date next to the field. These are averages, not offers.
Why is this different from my bank's calculator?
Usually the bank is including tax and insurance, adding its own fees, or using a different compounding convention. Ours is documented on the methodology page.
Can I use this for a property in another country?
Yes. Choose the country the property is in, not where you live — the mortgage follows the property's rules and currency.
Can I put this calculator on my own site?
Yes, free. The embed code is at the bottom of every country page and includes a link back to us.
