What is a fixed interest rate?

A fixed interest rate stays unchanged for an agreed period. That period may be shorter than the full loan term.

A simple example

A hypothetical 25-year loan might have its rate fixed for the first two years. The fixed-period end date and the final loan repayment date are two different dates to record.

What to keep in your records

Keep the agreed rate, fixed-period end date, lender and latest statement. Add the document explaining what happens after the fixed period, so it is easy to find when you review the loan.

A common mix-up

Fixed does not necessarily mean fixed for the entire loan. Early repayment or refinancing during the fixed period may involve costs under the contract. Read ASIC Moneysmart’s explanation.

Is a fixed rate always cheaper than a variable rate?

No. The outcome depends on future rates, fees and how you use the loan. The glossary explains the difference; it does not select a rate type for you.

Where can I check the meaning of fixed interest rate?

Use the ASIC Moneysmart source alongside the relevant statement or product documents. The examples here explain the term; they do not recommend a financial product.
