Quick answer
A variable rate is an interest rate the lender can change during the loan, so your repayments can rise or fall over time. In Australia, business lenders usually move their variable rates in response to the RBA cash rate and their own funding costs, though they aren't bound to match the RBA. Variable loans tend to allow extra repayments and early payout without break costs.
Key points
- The lender can lift or cut the rate while the loan runs, which changes your repayments
- Moves often follow the RBA cash rate, but each lender decides how much to pass on
- Usually more flexible than fixed: extra repayments and early payout without break costs
- Budget in dollars: work out what a rise would add to each month before you sign
On a variable rate loan, the price of borrowing isn’t locked in. The lender sets the rate today and keeps the right to change it later, so what you pay each month can climb or drop over the life of the loan.
That one feature shapes a lot: how you budget, whether you can repay early, and how exposed the business is when the economy shifts.
Who decides when a variable rate moves?
Your lender does. This is the part many owners miss. The Reserve Bank of Australia targets the cash rate, the price of overnight lending between banks, and it reviews that rate at eight board meetings a year. A change in the cash rate pushes on every lender’s funding costs, so banks and non-banks usually respond within days or weeks.
But the response is a commercial choice. A lender might pass on a cut in full, pass on part of it, or hold its rate because its own costs have moved differently. Many non-bank lenders raise money through wholesale markets rather than deposits, so their pricing can drift even in months when the RBA sits still. Your contract will say how much notice the lender must give before a change takes effect.

Why it matters when you borrow for a business
A variable rate turns your repayment into a moving target, so the real question is how much movement your cash flow can take. Lenders know this too. When they assess serviceability, many add a buffer and test whether the business could still meet repayments if the rate rose.
Products built for flexibility tend to be variable. A business line of credit or a business overdraft almost always carries a variable rate, because you draw and repay as you go. Short unsecured loans from online lenders, on the other hand, are often priced with a factor rate, which fixes the total payback upfront and has nothing variable about it.

Worked example: what a rise costs in dollars
Say a Geelong joinery borrows $400k on a variable, interest-only loan secured by commercial property. Interest-only keeps the maths simple, because the whole repayment is interest.
A quarter of a percentage point on $400k is $1,000 a year. So if the lender lifts its variable rate by that much, the joinery pays roughly $83 more each month. Two such rises in a year add about $2,000 to annual interest, around $167 a month. If the rate later falls back, the savings arrive the same way.
The owner’s job is to ask: if rates rose by a full percentage point, could we carry an extra $4,000 a year on this loan? If the answer is yes, variable gives flexibility at a manageable risk. If not, a fixed portion or a smaller loan may be wiser. Our business loan repayment calculator lets you test different scenarios.

Looking at a variable rate loan for your business?
Rate moves are only one piece. The bigger question is which lender will back your business on terms your cash flow can carry, especially if your bank has already passed. Banks are often the cheapest option when you fit their rules, and when you don’t, there are good non-bank and property-secured choices.

Frequently asked questions
How often can a variable rate change?
Whenever the lender decides, subject to the notice terms in your contract. In practice most lenders review their variable rates after RBA board meetings, which now happen eight times a year, and sometimes in between if their funding costs shift.
Does my business loan rate have to follow the RBA?
No. The RBA sets the cash rate, not your loan rate. Banks and non-banks often move after an RBA decision, but they can pass on more, less or none of it, and they can move at other times too.
Can I pay off a variable rate business loan early?
Usually yes, and often without a break cost. Check the letter of offer for any early repayment or exit fee, since some lenders charge one even on variable loans.
Is a factor rate a variable rate?
No. A factor rate is a fixed multiplier set when you sign, so the total payback is locked in from day one. It's common on short unsecured loans and merchant cash advances.
Should I choose variable or fixed for a business loan?
Variable suits owners who want flexibility, expect to repay early or can absorb a rise. Fixed suits owners who value certain repayments over a set period and don't plan to pay out early.
