A variable rate doesn't sit still. It moves with the RBA cash rate — up, and down.
Variable is now the default choice for the overwhelming majority of new borrowers — and for good reason. You get the fullest feature set of any loan (offset, redraw, unlimited extra repayments, and the freedom to refinance with no break costs), in exchange for one thing: when the cash rate moves, your rate and repayment move too. Here's exactly how that pass-through works.
How the cash rate flows into your rate — and your repayment.
Your variable rate isn't the cash rate. It's the cash rate plus a margin the lender sets for funding costs and competition. When the RBA moves the cash rate, that move typically flows through to variable rates within weeks — and your minimum repayment is recalculated at the new rate.
Across 2026 the cash rate rose +0.75pp — from the 3.60% trough (Aug 2025) back to 4.35% via three hikes — and on a variable loan that flows straight through: on this $600k example the illustrative repayment steps up about $288 a month. The upside is symmetry: when the cash rate falls, a variable repayment falls too, with no break cost to refinance or repay early. Figures are an indicative worked example only, not a quote, offer or a promise of any rate; your actual rate and repayment depend on the lender, product and your circumstances.
Flexibility on one side. Rate risk on the other.
A variable loan hands you the tools to get ahead faster — but the same feature that lets your repayment fall is the one that lets it rise. Both sides are real, so it's worth seeing them side by side.
Room to move
- Unlimited extra repayments. Pay as much extra as you like, whenever you like, with no penalty — the clearest advantage over fixed, and the fastest way to cut total interest.
- Offset & redraw. Most variable loans come with a linked offset account and redraw, so your savings work against the loan daily while staying accessible.
- Refinance freedom. No fixed term means no break costs — if a sharper deal appears you can reprice or refinance without penalty (standard discharge/government fees may apply).
- Falling rates flow to you. When the cash rate is cut, your repayment can drop — or keep paying the same and get further ahead.
Exposure to rises
- Rises flow straight through. A cash-rate increase typically reaches your loan rate within weeks, lifting your minimum repayment.
- Cycles can compound. Increases can arrive several in a row — over 2026 the cash rate rose +0.75pp — so budget for the trend, not a single move.
- Budgeting needs a buffer. Repayments can change with notice, so sensible variable borrowers never budget at the minimum.
- Lenders can move out of cycle. They set their own rates and aren't required to pass on cuts in full, which is why reviewing your rate regularly matters.
On a variable loan, a rate rise reaches you directly — so build for it.
Existing fixed borrowers are insulated for the rest of their term; variable borrowers are not. That's the deal you accept for the flexibility. The borrowers who handle rising cycles comfortably are the ones who prepared before the first increase — here's what actually happens, and how to stay ahead of it.
Your lender notifies you of the rate change before or when it takes effect.
Your minimum repayment is recalculated at the new rate over your remaining term.
If you've paid above the minimum or held funds in offset/redraw, you absorb the rise from the buffer you built.
Ask your lender for repricing — asking is free — or refinance, since there are no break costs holding you back.
Lenders already assess new applications at a buffer above the actual rate, but your own buffer is the best protection. Paying above the minimum and letting the surplus sit in offset turns rate risk into a savings habit — the buffer is yours either way.
General information only, not personal advice. Rates, features and fees vary by lender and are subject to assessment. Any rate figures shown are indicative and move with the RBA cash rate.
Three things that define a variable loan.
The rate can change any time
Your lender can raise or lower your rate over the life of the loan, largely tracking RBA cash-rate moves and its own funding costs. Your repayments adjust up or down accordingly, with notice.
The fullest feature set
Variable loans usually carry the complete toolkit: unlimited extra repayments, a redraw facility, and a linked offset account — the levers that let you cut interest and stay liquid at the same time.
Now the default choice
Fixed borrowing has collapsed since 2022 — under 5% of new and outstanding mortgages are on fixed terms today, so the overwhelming majority of new borrowers now choose variable.
Where variable rates sit — and why they've been rising.
Rates are indicative and move with the cash rate. These are benchmarks to frame a conversation, not an offer.

Rate figures are indicative only, move with the RBA cash rate, and are not an offer of credit. Comparison rates and fees vary by lender — compare the comparison rate, not just the headline rate.
Not sure variable is right for the whole loan? You can split.
You don't have to choose all-or-nothing. A split keeps part of your loan variable — with offset, redraw and unlimited extras — while fixing the rest for repayment certainty, so only the variable portion moves when the cash rate rises. Many borrowers start fully variable and fix a portion later if rate rises would genuinely strain the budget.
Structure is a personal decision that depends on your circumstances — general information only, not personal advice.
Variable rate loans, answered straight.
How does a variable rate home loan work?
Your interest rate can move up or down over the life of the loan at your lender's discretion, influenced by the RBA cash rate, funding costs and competition. When your rate changes, your minimum repayment is recalculated and your lender notifies you. In exchange for that movement, variable loans typically offer the most flexible features — offset accounts, redraw and unlimited extra repayments.
Does my rate change every time the RBA moves the cash rate?
Not automatically. Lenders set their own variable rates. They often move in line with RBA cash-rate changes, but they aren't required to pass on cuts in full, and they can move out of cycle in either direction. This is why comparing lenders — and reviewing your rate regularly — matters more on variable loans than any other type.
What happens to my repayments if rates rise?
Your lender will notify you of the change, and your minimum repayment will increase, recalculated over your remaining term. If you've been paying above the minimum or holding funds in offset, you can absorb rises more comfortably. Lenders also assess new applications at a buffer above the actual rate, but building your own buffer is the best protection.
Can I make unlimited extra repayments on a variable loan?
Generally, yes — most variable loans allow unlimited additional repayments with no break fees. This is one of the biggest practical advantages over fixed loans, where extra repayments are usually capped each year. Regular extras reduce the balance interest is charged on and can cut years off the loan.
Are variable rates negotiable?
Often, yes. Lenders commonly offer discounts off their standard variable rate, and existing borrowers can request repricing — especially when their loan-to-value ratio has improved or competitors are offering sharper deals. Asking costs nothing. If your lender won't move, refinancing is the lever, and there are no fixed-term break costs holding you back.
Can I switch from variable to fixed later?
Usually, yes — most lenders let you fix some or all of a variable loan at any time, at the fixed rates on offer that day (not the rates from when you first applied). Some borrowers start variable and fix a portion later if certainty becomes more important. Moving the other way — breaking a fixed rate early — is what attracts break costs.
