How Does the RBA Cash Rate Affect My Home Loan?

When the RBA changes the cash rate, banks typically pass on the full change to variable rate home loans within days. A 0.25% increase on a $600,000 loan adds approximately $94/month. Multiple rate changes compound — the 13 increases from May 2022 to November 2023 added over $1,200/month for the average Australian borrower.

Fixed rate loans are not affected immediately — but when your fixed period ends and you roll to variable, you face the current market rate. If you fixed at 2% in 2021 and your term expired in 2024, you moved to rates above 6% — a massive jump.

Disclaimer: This calculator provides estimates only. Your actual repayment change depends on your specific loan terms, lender, and any fees. Always confirm with your lender.

Frequently Asked Questions

How much does a 0.25% rate rise cost per month?

A 0.25% RBA rate rise costs approximately $62/month per $300,000 of loan balance. On a $600,000 loan that is roughly $124/month extra. Use the calculator above for your exact loan.

Will my bank automatically raise my rate if the RBA increases rates?

Variable rate customers typically see rates rise within days of an RBA increase. Fixed rate customers are unaffected until their fixed period ends.

How can I reduce the impact of a rate rise?

Make extra repayments to reduce your balance, use an offset account, switch to a lower rate lender, or fix a portion of your loan. Use our Offset Account Calculator to see how offset savings reduce your interest.
