Interest rates move in cycles over time, rising and falling in response to broader economic conditions. When the Reserve Bank of Australia (RBA) changes the cash rate, lenders may adjust their home loan rates in response.
Recently interest rates have increased, and for many Australians this means higher home loan repayments. With the cost of living already top of mind, even a small increase can feel significant. If you have a home loan, you might be wondering what this means for you, how it affects your repayments, and whether there’s anything you should be doing right now.
Whether you already have a home loan, are thinking about refinancing, or are planning your next property move, here’s what these changes could mean and how we can support you.
And if you’re just getting started, understanding how rate changes work can help you plan with greater confidence.
When the cash rate changes, lenders may adjust the interest rates on variable home loans. If your loan has a variable rate, this can mean a higher minimum required repayment.
If you are on a fixed rate, your repayments won’t change during the fixed period. If you are on a split loan, then only the variable portion may be affected.
You can use our Home Loan repayments calculator to estimate how these changes may affect your repayments here.
While variable interest rates may fluctuate, there are a few things you can do to help you feel more confident in your home loan:
When interest rates start moving, it's natural to wonder whether your current loan structure is still the right fit. The ideal type of loan for you in any interest rate environment is one that best suits your budget, income and lifestyle goals.
Here’s how the different types work, and what to consider for your needs.
In a fluctuating rate environment, some borrowers prefer to lock in a fixed rate for a period of one to five years. This means that your interest rates won’t change during this time.
This can make budgeting simpler, especially if you’re managing other rising costs.
However, it is important to be aware that fixed term loans come with some limits, for example, how much extra you can repay off the loan during the fixed rate period.
Also, fixed rate loans are locked into a contract. There can be fees involved if you wish to break the loan for any reason, such as if you refinance or sell your property.
For some, the trade-off is worth it for repayment certainty. For others, flexibility may be more important.
Variable interest rates can go up or down and CommBank will advise of any changes to your variable home loan rate via the CommBank website.
CommBank offers a variety of loan options and depending on the conditions of the loan, you may be able to do things like:
While a variable rate loan can be more flexible than a fixed rate one, there are potential downsides. If your lender increases rates, your mortgage repayments will increase, too. Consider how your budget could be impacted if your mortgage increased by $100 per month, $500 per month or even more. Planning for these scenarios can provide greater peace of mind even when rates are steady.
Alternatively, there is the option of a split loan, where a portion of your home loan is fixed and the remainder is variable. This can be the best of both worlds, offering both some degree of certainty but also the freedom to repay faster or redraw from the variable portion.
Choosing between a fixed, variable or split loan is an important decision and a great opportunity to set yourself up with a structure that supports your financial goals and budgeting preferences. Rather than trying to predict where rates might go, it’s about selecting an option that gives you the right balance of certainty and flexibility for your situation.

The RBA cash rate helps set how much it costs banks to borrow money. When this rate goes up or down, banks may change their home loan interest rates to reflect those costs and what’s happening in the wider economy. When this changes, banks review their interest rates to reflect broader funding and economic conditions.
You can find up to date information regarding interest rates on the CommBank website.
