Understanding the RBA Cash Rate Decision in 2026
The Reserve Bank of Australia (RBA) sets the official cash rate, which influences the interest rates that lenders offer on home loans. In 2026, the RBA announced a change to the cash rate, and this decision has a direct effect on the monthly repayments for Australian borrowers with variable-rate mortgages.
When the cash rate moves, lenders typically adjust their variable interest rates by a similar amount, though the timing and magnitude can vary. For borrowers, this means that a change in the cash rate can lead to either an increase or decrease in their monthly mortgage repayment.
How the Cash Rate Change Flows Through to Your Monthly Repayment
For a variable-rate home loan, your interest rate is tied to the lender’s standard variable rate, which is influenced by the RBA’s cash rate. When the RBA changes the cash rate, your lender may pass that change on to your interest rate. As a result, your monthly repayment amount will adjust accordingly.
The exact impact on your repayment depends on your loan amount, your remaining loan term, and how much of the rate change is passed through by your lender. It’s important to note that not all lenders pass on the full change, and some may adjust their rates differently.
Worked Examples for Different Loan Amounts
To illustrate the potential impact, consider the following examples based on a 25-year loan term and a 0.25 percentage point change in the cash rate that is fully passed through to the variable rate.
Example 1: $500,000 Loan
- Loan amount: $500,000
- Interest rate change: +0.25% p.a. (increase)
- Monthly repayment increase: approximately $68 per month
- Total interest over the loan term: increases by about $20,000
Example 2: $750,000 Loan
- Loan amount: $750,000
- Interest rate change: +0.25% p.a. (increase)
- Monthly repayment increase: approximately $102 per month
- Total interest over the loan term: increases by about $30,000
Example 3: $1,000,000 Loan
- Loan amount: $1,000,000
- Interest rate change: +0.25% p.a. (increase)
- Monthly repayment increase: approximately $136 per month
- Total interest over the loan term: increases by about $41,000
These examples are indicative only and assume a constant interest rate and principal-and-interest repayments. Actual figures will depend on your specific loan terms and the lender’s rate adjustments.
What Borrowers Should Consider
If you have a variable-rate home loan, it’s wise to review your budget to accommodate potential changes in your monthly repayments. You may also consider whether fixing your interest rate or refinancing could be beneficial, depending on your circumstances and market conditions. However, any decision should be based on your personal financial situation and advice from a qualified professional.

Frequently Asked Questions
How quickly does an RBA cash rate change affect my repayments?
Lenders typically adjust variable rates within a few weeks of an RBA decision, but the exact timing varies by lender. Your monthly repayment will change once the new rate is applied to your loan.
Does the cash rate change affect fixed-rate loans?
No, fixed-rate loans are unaffected by the RBA cash rate change during the fixed period, as your interest rate is locked in. The change will only apply when the fixed period ends and you revert to a variable rate or re-fix.
Can I reduce the impact of a rate rise?
You may consider making extra repayments, switching to a fixed rate, or refinancing to a lower rate. However, these options depend on your loan terms and lender policies.
