5 Ways to Tell if Your Interest Rate is Too High

Your home loan rate might be costing you hundreds of dollars more each month than it should. The rate you locked in two years ago or inherited when you first bought may no longer reflect what lenders are offering today, and the difference compounds over time.

Compare Your Rate Against Current Market Offers

Your rate is too high if it sits more than 0.30% above what similar borrowers are currently being approved for. Log into your loan account and check your current interest rate, then compare it against advertised rates for the same loan type. A variable rate sitting at 6.80% when new customers are accessing 6.20% means you're likely paying an extra $200 per month on a $500,000 loan.

Consider a borrower in Altona Gate who bought in late 2021 with a variable rate of 6.50%. That same lender is now offering 5.90% to new applicants with identical credit profiles. The difference over 25 years is substantial, yet many borrowers assume their existing rate adjusts automatically to remain competitive. It doesn't. Lenders rely on inertia, and your rate will remain elevated unless you actively refinance to a new lender or negotiate a reduction.

Check whether your loan includes an annual package fee or ongoing service charges that inflate the comparison rate. Some loans advertise low headline rates but add $395 in annual fees, which effectively increases the rate by 0.10% to 0.15% depending on your loan size.

Check How Long You've Been With the Same Lender

If you haven't switched lenders or renegotiated your rate in more than three years, you're almost certainly paying more than you need to. Lenders offer their most competitive pricing to attract new customers, not to retain existing ones. Loyalty doesn't reduce your rate, it increases it.

We regularly see Altona Gate residents who have held the same home loan for five or six years without reviewing their rate. The original product may have been competitive at the time, but rate movements and changes to lender pricing strategies mean that same loan is now 0.50% to 0.80% above current market offers. That gap translates to $250 to $400 per month in additional repayments on a $600,000 loan.

Request a rate review from your current lender before committing to a switch. Some will reduce your rate by 0.20% to 0.40% to retain your business, though the reduction rarely matches what you'd access by refinancing. If they refuse or offer less than 0.30%, start comparing external options.

Calculate What You're Actually Paying Over the Loan Term

An interest rate difference of 0.50% doesn't sound significant until you calculate the total cost. On a $550,000 loan with 23 years remaining, a reduction from 6.70% to 6.20% cuts monthly repayments by roughly $180 and reduces total interest paid by tens of thousands of dollars over the remaining term.

Use a refinance calculator to model your current loan against a lower rate scenario. Input your exact balance, remaining loan term, and current rate, then adjust the rate down by 0.30%, 0.50%, and 0.70% to see the monthly and lifetime impact. The results clarify whether refinancing justifies the time and cost involved.

Factor in any discharge fees from your current lender and application fees with the new lender when calculating net savings. Most discharge fees range from $300 to $500, while some lenders waive application fees entirely during promotional periods. If your monthly saving exceeds $150, refinancing typically pays for itself within three to four months.

Assess Whether Your Fixed Rate Has Rolled to Variable

Fixed rates that expire and roll to a lender's standard variable rate often jump by 1.00% or more overnight. If your fixed term ended in the past six months and you haven't taken action, your rate is likely too high by a significant margin.

As an example, a fixed rate of 4.80% that expires and rolls to a standard variable rate of 7.20% increases monthly repayments by around $650 on a $500,000 loan. Lenders send notification letters 30 to 60 days before expiry, but many borrowers don't recognise the urgency or assume the rollover rate will be competitive. It won't be. The standard variable rate is almost always the highest rate a lender offers, designed to encourage action rather than reward inaction.

Contact a broker or your lender at least 60 days before your fixed rate expiry to lock in a new rate or refinance externally. Waiting until after the expiry date limits your options and locks you into the higher rate for at least several weeks while any new loan is processed.

Review Your Loan Features Against What You're Paying For

If your rate sits above 6.50% but your loan includes no offset account, redraw facility, or rate flexibility, you're paying a premium for nothing. Some borrowers remain on older loan products with higher rates and fewer features simply because they haven't reviewed what's currently available.

Altona Gate buyers who purchased investment properties in the early 2020s may still hold interest-only loans with rates above 7.00%, even though similar investment loans with full offset and redraw now sit closer to 6.00%. The rate difference alone justifies refinancing, and gaining access to an offset account adds further value by reducing interest on any spare funds held in the account.

Compare your current loan statement against product disclosure statements from at least three other lenders. Look specifically at the interest rate, comparison rate, offset availability, and any restrictions on extra repayments. If your current loan ranks last on every measure, switching becomes a straightforward decision.
