One of the most common money mistakes Australian homeowners make is setting and forgetting their mortgage. You shop around when you buy — then don't look again for years while the market moves on without you.
So how often should you actually review your home loan rate? The short answer: at least once a year. Here's why, and what to look for when you do.
Why Annual Reviews Matter
The home loan market is competitive and constantly changing. Lenders regularly offer better rates to attract new customers — while quietly leaving existing customers on older, higher rates. This gap is sometimes called the loyalty tax.
According to the RBA, the average gap between the rate paid by new borrowers and existing borrowers has historically been 0.3–0.5% per annum. On a $600,000 loan, that's $1,800–$3,000 per year in unnecessary interest.
What Triggers a Review?
Beyond the calendar, certain events should prompt an immediate review:
- RBA cash rate changes — When the cash rate drops, your variable rate should follow. If it doesn't, that's worth querying.
- Your fixed rate is expiring — The 6–12 months before your fixed term ends is prime time to compare.
- Significant equity gain — If your property has increased in value, your LVR has improved and you may qualify for better rates.
- Your financial position has changed — Better income, lower debts, or improved credit can unlock better pricing.
- You've been with the same lender 3+ years — The loyalty tax is real and compounds over time.
What to Look at During a Review
Don't just check the interest rate — review the full package:
- Interest rate vs comparison rate
- Offset account: is yours fully transactional?
- Redraw: are there fees?
- Annual fees and monthly fees
- Break costs if you're on fixed

How to Actually Do a Rate Review
There are three approaches — each with different effort levels:
1. Call Your Lender Directly
Ask the retention team for a rate reduction. Many lenders will offer 0.1–0.25% off just to keep you. Easy win, but it caps how much you'll save.
2. Use a Comparison Website
Sites like Canstar or RateCity show advertised rates, but these may not reflect what you'd actually qualify for, and they often miss non-bank lenders.
3. Use a Mortgage Broker
A broker can check your actual rate against 30+ lenders in 20 minutes, including ones that don't advertise publicly. They handle the application if you switch, and they're paid by the lender — not you.
How Much Could You Save?
A 0.5% rate reduction on a $700,000 loan over a 25-year term saves approximately $90,000 in total interest. Even a 0.25% reduction saves around $45,000.
Even after refinancing costs (discharge fees ~$300, new loan setup fees ~$300–$600), most borrowers recoup the cost within 6–12 months.
The Bottom Line
Review your home loan rate every 12 months at a minimum. Set a calendar reminder. The best time to do it is during a quiet period — not when you're about to buy or sell. Even 30 minutes a year could be worth thousands.
