Fixed vs variable: how to actually choose

Fixed or variable is one of the first big decisions on a home loan, and it's often framed as a bet on where rates are heading. It's better understood as a question about what you value: certainty, or flexibility.

What a fixed rate gives you

Fixing locks your rate — and therefore your repayment — for a set period, usually one to five years. The appeal is certainty: your repayment won't move even if rates rise, which makes budgeting easy and protects you in a rising-rate environment. The cost is flexibility. Fixed loans often limit extra repayments, may not offer a full offset account, and can charge significant break fees if you repay early, refinance, or sell during the fixed term.

What a variable rate gives you

A variable rate moves with the market — up or down. You give up certainty, but you gain flexibility: typically unlimited extra repayments, a genuine offset account, and the freedom to refinance or sell without break costs. If getting ahead on your loan and keeping your options open matters to you, variable is usually the more powerful structure.

You don't always have to choose

Many borrowers split the loan — part fixed, part variable. That gives you a predictable core repayment plus the flexibility and offset benefits of a variable portion. It's a practical middle path when you want some certainty without fully giving up the features that help you pay down the loan faster.

How to decide

Ask yourself how much repayment certainty you need to sleep at night, whether you're likely to sell or refinance within a few years (which makes fixed risky), and how much you value an offset and extra repayments. There's no universally correct answer — only the structure that fits your plans. That's the conversation worth having before you commit.
