Home loan interest rates

Home loan interest rates: what they are and why they matter more than you think

When you're applying for a mortgage, one factor can make or break your budget: your home loan interest rate. It determines how much you'll pay each month and how much you’ll end up paying over the life of the loan. Even a small difference, like 0.25% in interest, can translate to thousands in savings or extra cost over the years.

• Your interest rate affects your repayment amount, your ability to build equity, and your long-term financial flexibility. That's why choosing the right type of rate and negotiating the best deal possible is just as important as picking the property itself. In a shifting economic environment, understanding how rates work and what drives them is essential.

What influences home loan interest rates?

Lenders set their home loan interest rates based on multiple factors some economic, others personal:

• RBA cash rate: The Reserve Bank of Australia’s official rate influences the cost of borrowing for banks.

• Lender funding costs: Banks may adjust rates depending on how much it costs them to access funds.

• Loan-to-Value Ratio (LVR): A lower LVR often means lower rates because the risk to the lender is lower.

• Credit profile: Good credit history and stable income can help you secure more competitive rates.

• Loan type and purpose: Rates may differ for investment vs owner-occupied properties.

• Fixed or variable: Fixed rates are often slightly higher, as they provide predictability to borrowers.

Your personal circumstances can also affect the deal you’re offered. That’s why using a broker who understands lender policies is essential they know who’s likely to approve you and at what rate.

How to compare home loan interest rates effectively

To make an informed decision, don’t just look at the interest rate alone. Consider the full structure of the loan. Here’s what to assess:

• Comparison rate: Includes most fees and charges, giving a more realistic cost of the loan.

• Loan features: Look for offset accounts, redraw options, and the ability to make extra repayments.

• Introductory vs revert rate: Watch out for "honeymoon" rates that spike after 1–2 years.

• Flexibility: Can you refinance easily? Are there exit or break fees?

• Customer service: Faster approval and ongoing support can make a big difference.

HeyNest brokers do all of this for you analysing products across 30+ lenders and hundreds of loans to help you pick the right fit.

Why do fixed rates cost more than variable rates?

Fixed rates provide certainty to borrowers but shift interest rate risk to the lender. To account for that risk, lenders typically charge more upfront. You're paying a premium for stability, which may or may not pay off depending on future rate movements.

Can I switch from fixed to variable during the loan?

Yes, but break costs or penalties may apply, especially if rates have changed significantly. Check the exit conditions in your loan agreement before committing. It's best to work with a broker to explore whether refinancing or restructuring makes financial sense.

How often do interest rates change?

Variable interest rates can change monthly depending on economic data and RBA rate decisions. Lenders can also adjust rates independently. Fixed rates change less frequently but are influenced by market trends and lender funding costs.
