Interest Rate Reduction: What It Means for Your Home Loan Repayments

The Reserve Bank of Australia (RBA) has reduced the cash rate for the first time since November 2020, lowering it by 0.25 percentage points to 4.1% at its latest meeting. In response, most banks have announced that they will pass on the full rate cut, with interest rate reductions taking effect on various dates.
This change presents a valuable opportunity for homeowners to reassess their mortgage repayments and potentially save thousands over the life of their loan.
How Interest Rate Reduction Affect Your Mortgage Repayments
Principal and Interest (P&I) Repayments
When interest rates decrease, the interest portion of your mortgage repayment also reduces. However, this does not necessarily mean that your monthly repayment amount will automatically change. Lenders typically take one of two approaches when adjusting Principal and Interest (P&I) repayments:
Some lenders will automatically lower your minimum required repayment to reflect the reduced interest rate.
Other lenders may maintain your current repayment amount despite the rate drop—unless you request an adjustment.
If your lender keeps your repayment at the same amount, you could shorten your loan term and reduce the total interest paid. For instance, if you have a $500,000 home loan and your interest rate decreases from 6.2% to 5.95%, your minimum monthly repayment would fall from $3,052 to $2,980. However, if you continue paying $3,052, you could reduce your loan term by approximately one year and save thousands in interest.
For those who prefer to adjust their repayments to the new minimum, most banks allow changes via their online banking platforms or through direct contact.
This lower interest rate environment presents a great opportunity for borrowers. If you can afford to maintain your current repayment level, you can accelerate your loan payoff and reduce long-term interest costs.
Alternatively, if you need more financial flexibility, lowering your repayments to match the new minimum can help ease monthly cash flow constraints.
Interest-Only Repayments
If you have an interest-only mortgage, your repayments will automatically decrease when rates are reduced, as your repayments consist solely of interest charges. This can free up additional cash flow, which borrowers may choose to reinvest, save, or allocate toward property-related expenses.
Will Lenders Automatically Reduce Your Repayments?
For borrowers with P&I loans, different banks and lenders have varying policies regarding whether repayments will automatically adjust to reflect the new interest rate (aka the interest rate reduction). Some lenders will require manual action through internet banking or direct contact to implement the lower repayment amount. The table below outlines major Australian lenders and whether they will adjust repayments automatically or if manual action is required:
