A lower advertised rate can catch your eye, but it does not tell you how a home loan will fit your day-to-day finances. Fixed and variable loans can differ in how repayments change, how extra repayments are treated and which features are available. Before comparing rates, decide what you need the loan to do.
What fixing your rate changes
With a fixed-rate loan, the interest rate is set for an agreed period, so the rate on that portion of the loan does not move when market rates change during that term. This can make repayments more predictable for a while. It does not mean the loan is free of conditions: limits may apply to extra repayments, and changing or ending the loan early can involve costs.
A variable rate can move over time, so repayments or the amount of interest charged may change. Variable loans may offer features such as an offset account or redraw, but availability and conditions vary between products. Check how a feature works in the specific loan rather than assuming every variable loan offers the same flexibility.
Consider your plans and flexibility
Think about what might change during the loan term. You may want to make extra repayments, use savings in an offset account, renovate, or sell and move before a fixed period ends. If your income or household costs vary, consider how you would manage if a variable rate rose or a fixed period expired.
Compare the full loan
Compare the rate alongside fees, repayment rules, available features and the conditions attached to them. If a loan splits the balance between fixed and variable portions, check how repayments and features apply to each part. A split can combine some rate certainty with some flexibility, but it also means keeping track of two sets of terms.
Write down the features you would actually use, then compare eligible loans against that short list as well as their rates and costs. The best comparison is not simply fixed versus variable; it is how each option handles the trade-offs that matter to your household.
