What Rising Interest Rates Mean for Your Home Loan

Interest rate rises make headlines. But what do they actually mean for your mortgage, your repayments and your long-term financial position? Here is what you need to know.

How rate rises affect your repayments

When the Reserve Bank of Australia raises the cash rate, variable home loan rates typically follow within weeks. On a $600,000 loan, a 0.25% rate increase adds roughly $95 per month to your repayments. A full 1% increase adds around $380 per month. Over a year that is $4,560 out of your pocket that was not there before.

Fixed rate borrowers are protected until their fixed term expires. When it does, many roll onto a variable rate that is significantly higher than what they were paying - often referred to as the fixed rate cliff.

Should you fix, stay variable or split?

There is no universal answer. Fixed rates provide certainty but remove flexibility - you generally cannot make large extra repayments or access an offset account during a fixed period. Variable rates move with the market but give you full flexibility. A split loan gives you a portion of both.

The right choice depends on your income stability, how long you plan to hold the property, and where rates are likely to move. Getting this decision wrong can cost you significantly over the life of the loan.

Refinancing in a rising rate environment

Rate rises are often the trigger people need to review their existing loan. Many borrowers are paying their lender's standard variable rate - often 0.5% to 1.5% higher than what a new customer would be offered today. Loyalty rarely pays in mortgage lending.

Refinancing to a lower rate or better product can offset the impact of rate rises entirely. On a $600,000 loan, moving from 7.25% to 6.25% saves around $380 per month - effectively neutralising a 1% rate increase.

What rate rises mean for investors

For investment property owners, rising rates increase holding costs. However, higher interest expenses also mean larger tax deductions. The net impact depends on your tax position, rental income and loan structure. A well-structured investment loan can significantly reduce the after-tax impact of rate increases.

The most important thing you can do right now

Review your current rate. If you have not refinanced in the last two years, there is a strong chance you are paying more than you need to. A mortgage broker can assess your current loan against the market in minutes and tell you whether switching makes financial sense.
