The key decision

A fixed interest rate can make the interest basis predictable for its fixed period. A variable rate can change with its specified benchmark. Neither label explains fees, total cost or repayment flexibility on its own.

What to consider before choosing

Read how a variable rate resets, what benchmark and margin apply, and whether there is a floor. For a fixed offer, check the fixed period and early-repayment provisions. Compare both offers at the same principal and term, then test a rate increase and an early-exit scenario. Do not forecast future rates as a certainty.

Your preparation checklist

  • Record the rate formula and reset frequency.
  • Test a higher-rate payment in the cash forecast.
  • Compare payout costs at the date you might refinance.

Build a one-page funding brief

Write down the amount the business actually needs to receive, the purpose, the payment deadline and the cash event that repays the facility. Include a current debt schedule rather than discussing the new proposal in isolation. When comparing structures, use the same starting assumptions. A larger approved amount, a longer term or a smaller instalment changes the decision and should not be mistaken for a better price.

A bank, programme lender, non-bank provider and broker can play different roles. Identify the actual contracting party and ask which conditions remain. Where the contract, guarantee or local regulatory position is unclear, obtain qualified advice before signing.

Hypothetical planning example

Put the decision into numbers

Illustration: a variable proposal with a lower starting rate may still be unsuitable if a higher payment would consume the entire cash buffer. A fixed proposal can also be costly to exit early.

This is an illustration, not a customer case, provider quote, approval or market benchmark. Unless a currency is stated, use one consistent currency throughout your own calculation.

What to watch

A fixed payment does not always mean the underlying interest rate or total term is fixed.

A question worth asking

Which payment, rate or maturity terms can change during the agreement?

Take the next practical step

Compare written offers using the same net funding and cash-flow assumptions. Start with the offer comparison checklist or run a cost and cash-buffer calculation. Keep sensitive financial records out of a general enquiry until a secure document route is confirmed.
