Fixed versus variable: What’s the difference in a nutshell?

A fixed interest rate

If your loan has a fixed interest rate, the rate of interest you’re charged won’t change for a set period. This means your repayment amount won’t change and can give you more certainty about the total amount you need to pay back.

Fixed interest rate personal loan: The interest rate and your repayments stay the same for the entire duration of the loan.

Fixed interest rate home loan: A fixed rate home loan also has a set fixed period. During this time, your interest rate and required repayment amount stay the same during the fixed period. When the fixed period is finished, the loan will often revert to a variable home loan rate, unless you arrange with your lender to fix it again.

A variable interest rate

If your loan comes with a variable rate, the interest rate you’re charged and your required loan repayments can go up or down. The interest rate on a loan can change for a number of reasons, including decisions by the Reserve Bank of Australia and overall market conditions.

Fixed and variable rates both have potential benefits. Knowing what these are will help you decide which option is best for you.

The benefits of a fixed rate

Budgeting

With a fixed rate loan, you should know at the outset how much you’ll need to pay back. This means you can work out what you’ll be paying weekly, fortnightly or monthly and when your loan will be paid out. Knowing that your regular payments won’t change can be helpful for budgeting. It means you’ll know exactly how much you need to set aside for your loan repayments.

Peace of mind

Interest rates can rise and fall due to a number of factors as mentioned above, all of which are out of your control. Knowing that the interest rate you are charged won’t go up can offer borrowers great peace of mind (you won’t have to take a deep breath every time interest rates are mentioned on the news). On the flip side, you won’t benefit from rate decreases if they happen.

Other things to consider with a fixed loan

With a fixed loan, if you decide to change your financial institution, or pay off your loan early, some lenders may charge an early payout fee. There are also often restrictions on making extra repayments on your loan while it’s fixed. Make sure to look carefully at the loan terms and conditions so you know what restrictions and fees might apply.

The benefits of a variable rate

Opportunity to save

With a variable rate loan, if interest rates go down, you can save on the amount of interest you have to pay back. Although it’s always worth bearing in mind that if interest rates rise, your minimum loan repayments are likely to go up.

Greater flexibility

Variable loans often allow the borrower to have greater control over how they make their repayments. For example, with some variable loans you can make unlimited extra repayments if you have some extra cash. With fixed rate loans, this is generally restricted or has a capped limit on the extra repayments allowed. In general, fixed rate loans have less additional options compared to variable loans.

For fixed rate loans, most lenders will also charge an early payout fee, while there is no penalty for paying out a variable loan early. However, all loans will have a discharge fee which covers the lender’s legal costs.

This is applied where the borrower:
* pays out a loan and requires the discharge of a mortgage
* pays out part of a loan or refinances through another financial institution, requiring the release of a security.

Potentially a lower interest rate at the start

Variable loans often come with a lower initial interest rate than fixed loans. This is because with a fixed loan you’re paying to ‘lock in’ that rate for a set period.

Are there any other options?

Some lenders allow you to split your loan (typically your home loan) between fixed and variable, to enjoy the benefits of both worlds. These options offer a combination of the certainty of a fixed rate as well as the flexibility of a variable rate. Extra fees, charges and restrictions on these types of loans may apply and vary amongst lenders. Make sure you’re informed about any costs involved upfront before committing to this, or indeed any, type of loan arrangement.
