The impact of a variable rate home loan as interest rates change

There were a series of interest rate increases, beginning in May 2022, and reaching its peak in November 2023. Rates then remained unchanged at 4.35% until the 0.25% cut in February 2025. A recent study, Five Economic Themes That Will Dominate the Next Parliament1, has revealed the consequences of the RBA interest rate hike cycle, with variable-rate mortgage holders having around $800 a month in additional repayments between mid-2022 and early 2024.

The research found that variable-rate mortgage holders paid $13,884 more in repayments than fixed-rate mortgage holders over the 18 months following interest rate rises.

This period of inflated interest rates placed immense strain on borrowers, especially those who were on a variable rate.

Despite the added strain, the study found that spending habits between fixed and variable rate mortgage borrowers hardly changed. 70% of borrowers funded the increases in mortgage repayments using savings. Just 26% had paid for the increased mortgage repayments with additional income streams.

The rate hike cycle also limited the number of people making excess mortgage repayments.

The research revealed that 70% of variable-rate borrowers made excess mortgage repayments before the rate hike cycle. As of the end of the study in April 2024, this dropped to around 25%.

The fluctuations in interest rates demonstrate the importance of establishing and maintaining an emergency fund buffer as an integral component of your strategic financial planning.
