Fixed vs Variable Rate Business Finance

Choosing between a fixed and a variable interest rate comes down to a trade-off: certainty versus flexibility. Neither is universally better — it depends on your cash flow and your view on rates.

Which Should You Choose?

Best for…

Fixed rate

  • You want certainty for budgeting
  • You expect rates to rise
  • Tight margins where surprises hurt
  • You don’t plan to repay early

Variable rate

  • You want to make extra repayments
  • You may pay the loan out early
  • You expect rates to fall or hold
  • You can absorb some movement

The verdict

If predictable repayments help you sleep at night and protect tight margins, fix the rate. If you want the freedom to overpay, repay early or benefit from falling rates, go variable. Some lenders even allow a split. We’ll show you fixed and variable options across our panel so you can decide with real numbers.

FAQ

Common questions

What are break costs on a fixed-rate loan?

If you repay or refinance a fixed loan early, the lender may charge a break fee to recover the interest they expected. The amount varies, so always check the terms before fixing.

Can I switch from variable to fixed later?

With many lenders, yes — though terms and any fees vary. If you think you’ll want to fix later, tell us upfront and we’ll prioritise lenders that allow it.

Is a split (part fixed, part variable) possible?

Some lenders offer a split facility, giving you certainty on part of the balance and flexibility on the rest. We can compare lenders that support this.

Which is better for a short-term loan?

For very short terms the difference is often small. Flexibility to repay early (variable) can be valuable if you expect to clear the loan quickly.
