How to Pay Off Your Mortgage Faster: A 10-Minute Mortgage Health Check

By Andrew Paterson

You will hunt for a discount code before ordering a $20 pizza. Yet the six-figure home loan sitting behind your front door often goes years without a second glance.

That gap is where thousands of dollars quietly leak away.

Learning how to pay off your mortgage faster does not start with a fancy product or a refinance. It starts with a 10-minute health check on the loan you already have.

Let’s run through it together.

The minimum-repayment trap nobody warns you about

Your lender calculates a minimum repayment. Most people pay exactly that, set and forget, and never look again.

The problem is how a loan front-loads interest in the early years.

Take a $600,000 loan at 6.2% over 30 years. The monthly repayment is roughly $3,676.

Here is what the first payment actually does:

• About $3,100 goes straight to interest
• Only about $576 chips away at what you borrowed

Over the full 30 years that same loan costs around $723,000 in interest. Total paid lands near $1.323 million.

Sit with that for a second. On a $600k debt you can hand the bank more than the original loan amount again, just in interest.

Paying only the minimum is not wrong. But doing it on autopilot for 30 years is the most expensive habit in Australian housing.

The new 2026 version of the trap: 40-year loans

There is a fresh twist worth flagging. Forty-year loan terms are now a live option in Australia.

As of 2026, eleven lenders offer them, including AMP Bank, Great Southern Bank, Pepper Money, RACQ Bank and Liberty. The Big Four still do not.

A longer term lowers your monthly repayment. That feels like relief when rates are climbing.

But the maths is brutal. On a $600,000 loan, stretching from 30 to 40 years adds roughly $288,000 in extra interest over the life of the loan.

Finder research found around 30% of Australians, close to 6.2 million people, would consider a 40-year loan for lower repayments.

A 40-year term can genuinely help someone manage cash flow through a tight stretch. The danger is treating a lower minimum as a win rather than a longer, costlier road. Weigh it as a considered trade-off, not a default.

Your 5-point mortgage health check

Grab your latest loan statement and your banking app. This part takes about ten minutes.

Run these five checks.

1. Your rate versus the market

Find your current interest rate on your statement. Then benchmark it.

A quick note on averages, because sources genuinely disagree:

• Mozo and RBA lender data put the average variable rate near 5.90%
• Finder’s product-database average sits closer to 6.90%

The difference is methodology. RBA data draws from actual loans on lender books. Finder averages advertised products across its database.

The most competitive advertised rates start around 5.69%. Big Four headline variable rates sit around 6.50% to 6.69%, though brokers often secure discounts of 50 to 100 basis points for new business.

If your rate has a 7 in front of it, that is your first red flag.

2. Is your offset or redraw actually working?

Plenty of people pay for an offset account and leave it near empty. Others tip spare cash into redraw and forget it exists.

Check whether you have either feature. Then check whether it is doing anything.

Worth knowing in 2026: reports have surfaced of offset calculation errors costing borrowers money. Confirm your offset balance is actually being applied against your loan, not just sitting there for show.

3. Years remaining versus your original term

If you took a 30-year loan five years ago and refinanced back to 30 years since, you may have quietly reset the clock. Twice.

Every reset drops you back into the interest-heavy early years. Check where you actually stand.

4. Repayment frequency

Are you paying monthly or fortnightly? This one is small to change and adds up fast.

More on the maths below.

5. Are you only ever paying the minimum?

Look at the last twelve months. Have you ever paid a cent more than required?

If the answer is no, you are the set-and-forget borrower this whole article is written for. No judgement. Just opportunity.

Small changes, big numbers

Here is where it gets satisfying. You do not need to win the lottery to cut years off a loan.

Switch to fortnightly repayments

Pay half your monthly amount every fortnight. There are 26 fortnights in a year, which equals 13 monthly payments instead of 12.

You sneak in one extra month of repayments a year without really feeling it.

On a typical 30-year loan that can save around 4 to 5 years and $60,000 or more in interest.

One catch. Confirm with your lender that fortnightly repayments are set at half the monthly figure. Some lenders set them so no acceleration happens, and then the benefit disappears.

Add a modest extra repayment

Consider a $700,000 loan at 6% over 30 years. Add $500 a month on top of the minimum.

The result:

• Around $175,000 saved in interest
• Roughly 8 years cut off the term

Not everyone has $500 spare. But even a fraction of that, paid consistently, moves the needle.

Shave your rate

Cutting your rate by half a percent matters more than most people expect.

On that $600,000 loan over 30 years, dropping from 6.2% to 5.7% saves around $65,000 in total interest.

That is the pizza-code logic flipped on its head. A ten-minute conversation can be worth tens of thousands.

A Geelong worked example

Let’s ground this locally. The median Greater Geelong house sits around $793,000, up 3.2% over the year to early 2026.

Say you buy at that median with a 20% deposit. Your loan is roughly $634,000.

At 6.2% over 30 years:

Strategy	Rough outcome
Minimum only, 30 years	Baseline interest cost, full term
Switch to fortnightly	~4-5 years and ~$60k+ saved
Add $500/month extra	Around 8 years and six figures of interest saved
Trim rate by 0.5%	Tens of thousands saved over the term

Stack two or three of these together and you can reshape the loan entirely. That is the point of the health check. Small levers compound.

Offset account versus extra repayments

This is one of the most common questions we field. The honest answer is that dollar for dollar, both save you roughly the same interest.

The real difference is access.

• Offset: money stays in an account linked to your loan and offsets the balance. You can withdraw it any time.
• Extra repayments: money goes onto the loan directly. To get it back you use redraw, which can carry restrictions or delays.

So who does an offset suit? Not only people with a big balance sitting there today.

An offset can suit someone building savings over time. It can suit someone with lumpy or irregular income, like a tradie or a business owner, who wants a buffer they can reach.

It can also suit someone who may rent the place out later, where keeping cash available rather than locked in the loan carries tax and flexibility considerations.

The right structure depends on your goals and how your situation might shift. That is exactly what a broker sits down and works through with you.

Why the rate environment makes this urgent right now

A lot of “pay off your mortgage faster” articles assume rates are low and falling. That is not the 2026 picture.

The RBA cash rate sits at 4.35% as at August 2026. The Bank raised rates three times through 2026, adding 75 basis points before pausing.

The next decision lands on 29 September 2026, and markets consider a further hike likely.

Inflation is still running hot. Headline CPI hit 3.5% in July 2026 with the trimmed mean at 3.6%, both above the 2 to 3% target band.

When rates were falling, complacency cost you a little. When rates are rising, reviewing your loan matters more, not less.

One more thing worth knowing. Lenders must assess you at 3 percentage points above your loan rate under the APRA serviceability buffer. That affects what refinancing options are open to you, so it is worth understanding before you assume you are stuck.

If you are still buying: two quick wins

Not on the ladder yet? Two points can save you serious money before you even settle.

Lenders Mortgage Insurance. Borrow above 80% of the property value and you typically pay LMI, often $10,000 to $40,000 depending on loan size and LVR. On larger loans it can top $30,000.

The First Home Guarantee. Eligible first home buyers can purchase with a 5% deposit and avoid LMI entirely. From 1 October 2025 the income caps were removed.

The average first home buyer loan reached $614,000 in the March 2026 quarter, so avoiding a five-figure LMI bill is a real head start.

What to do next

Run the five-point health check today. It costs you nothing but ten minutes.

Then play with an extra-repayments calculator using your real loan size and rate. Seeing your own numbers move is what turns intention into action.

If your rate has a 7 in front, your offset is empty, or you have never paid a dollar over the minimum, that is your signal to get a second set of eyes on it.

A proper loan review is what we do at Aussiewide. No pressure, just a look at whether your current setup still fits where you are heading.

You would grab the pizza code. Your mortgage deserves at least the same attention.

All interest rates, the RBA cash rate (4.35% as at August 2026), average rates, thresholds and scheme rules are time-sensitive and were current at the date of writing. Verify current figures before relying on them. The RBA next decides on 29 September 2026 and a further hike is considered likely.

All repayment, interest-saving and offset figures are illustrative estimates only. They assume a constant interest rate and consistent repayments. Actual results depend on your rate, balance, fees, redraw or offset terms and repayment behaviour, and will differ.

Compare loans on the comparison rate, which includes most fees, not the headline rate alone.

Frequently asked questions

How much faster can I pay off my mortgage with extra repayments?

It depends on your loan size, rate and how much extra you pay. As an illustration, adding $500 a month to a $700,000 loan at 6% over 30 years can save around $175,000 in interest and cut roughly 8 years off the term. These figures are estimates only and assume a constant rate and consistent repayments.

Is an offset account better than making extra repayments?

Dollar for dollar they save you roughly the same interest. The difference is access. Offset money is withdrawable any time, while extra repayments can only be recovered through redraw, which may carry restrictions. Which suits you depends on your goals, income patterns and whether your situation might change, so it is worth talking through with a broker.

What is the average home loan interest rate in Australia in 2026?

Sources differ by methodology. Mozo and RBA lender data put the average variable rate near 5.90%, while Finder’s product-database average sits closer to 6.90%. The most competitive advertised rates start around 5.69%. Always compare on the comparison rate rather than the headline figure, and check current rates before deciding.

Does switching to fortnightly repayments really help?

Often yes, if set up correctly. Paying half your monthly amount every fortnight means 26 payments a year, equal to 13 monthly payments instead of 12. On a typical 30-year loan that can save around 4 to 5 years and $60,000 or more in interest. Confirm with your lender that fortnightly is set at half the monthly figure, as some lenders set it so no acceleration occurs.

Should I get a 40-year home loan to lower my repayments?

A 40-year term lowers your monthly repayment, which can help through a tight cash-flow period. But it costs far more overall. On a $600,000 loan, stretching from 30 to 40 years adds roughly $288,000 in extra interest. Eleven lenders offer them in 2026, though the Big Four do not. Treat it as a considered trade-off, not a default choice.
