Interest rates directly affect the cost of borrowing. For variable-rate loans, even a small rate change can increase repayments and put additional pressure on your household cash flow, particularly when the loan balance is high.
How Do Higher Rates Affect a Mortgage?
For a variable-rate mortgage, a higher interest rate generally increases the interest charged and can increase required repayments. The effect depends on the balance, remaining term and loan structure.
What About Fixed-Rate Loans?
A fixed rate may protect repayments from rate changes during the fixed period, but the loan can move to a different rate when the fixed term ends. This can create repayment shock if the new rate is a lot higher.
How Do Rates Affect Credit Cards?
Credit-card interest rates are often much higher than mortgage rates. Carrying a balance for long periods can therefore be expensive even if broader interest-rate changes are modest.
What Can You Do When Rates Rise?
- Review your household budget
- Check whether the loan is still competitive
- Direct extra repayments to high-cost debt where appropriate
- Build or maintain an emergency buffer
- Stress-test repayments against further rate increases
Should You Refinance?
Refinancing can reduce interest in some cases, but compare fees, loan term and total cost. Extending the repayment period can lower the monthly repayment while increasing total interest.
Interest Rates Affect Financial Goals Too
Higher debt repayments can reduce the amount available for super, investments, travel and other goals. The right response may therefore involve reprioritising the whole financial plan rather than looking only at the loan.

Frequently Asked Questions
Do all loans change when rates change?
No. Variable rates can change, while fixed loans generally remain fixed for the agreed period.
Should I refinance every time another lender is cheaper?
Not automatically. Compare fees, features, loan term and total cost before switching.
Can extra repayments reduce interest?
Depending on the loan, reducing principal sooner can reduce future interest. Check loan terms and any restrictions.
