No one wants to pay more interest than they have to.

However, most people think in order to pay less interest on your mortgage, you must make big extra repayments or radically change your lifestyle.

The truth is, you can save thousands of dollars in interest costs by simply being strategic with the way your loan is set up and how you manage it over time.

Here are 10 smart ways you can reduce the amount of interest you pay on your mortgage…

10 Smart Ways To Pay Less Interest On Your Mortgage

1: Choose The Right Loan Structure

The structure of your loan will determine how much flexibility you will have to reduce the interest you pay in both the short and long term. Mixing up your fixed terms or even having a split between fixed and floating portions can create opportunities to pay more off the principal without penalty.

The right structure can easily save you tens of thousands over the lifetime of your mortgage.

2: Align Your Loan Terms With Your Future Plans

Many homeowners are guilty of locking in their mortgage terms without really thinking ahead. They look at the rates and lock in based on that. But, if you are planning on renovations, refinancing, or selling within the next few years, setting up shorter fixed terms can save you money on break fees and even give you access to better rates sooner.

Likewise, if you intend to stay put in your property for a while, longer term rates can be attractive for stability, and you can always increase your repayments slightly to bring the interest portion down.

3: Don’t Mortgage Your Fees

It can be very tempting to roll any legal fees, application costs and loan setup charges into your mortgage. But, if you do that, you will be paying interest on those small costs for decades to come, making them much larger costs.

By paying these fees upfront, you can significantly reduce your long-term interest bill.

4: Maximise Your Banking Setup

Offset accounts, revolving credit facilities, and even a well-chosen transaction account can dramatically reduce the interest you pay. The simple act of keeping your income sitting against your mortgage, even if it’s just for a few days before the bills come out, can seriously cut down on interest costs.

5: Kick The High-Interest Debt First

High-interest debt, like credit cards, personal loans or buy-now-pay-later schemes, is guilty of quietly stealing the money you could be putting towards your mortgage. If you are only paying the minimum payment on these debts, you will be incurring lots of interest, often charged upwards of 20%!

Clearing those debts faster frees up your cash so that you can put it against your home loan instead. This will save you interest in both areas!

6: Line Your Repayments Up With Your Income

You don’t need to take whatever date the bank gives you for your repayments. Instead, chat with them about aligning your repayment dates with your income cycle.

That way, if you are using things like an offset account, you can maximise the efficiency of this. With the right set-up, when your salary lands in your account, it will immediately offset your home loan, reducing your loan’s average daily balance and the interest charged.

7: Review Your Mortgage Annually

Many homeowners set up and forget their mortgages, only revisiting them when a fixed term portion is about to expire. A lot can happen in that time – interest rates can move quickly, bank policies can change, and your financial situation could evolve.

A quick annual review with your mortgage adviser can identify whether your mortgage is still competitive, if another bank is offering better incentives, or whether restructuring could save you interest.

8: Consider All The Terms When You Refix

How long you should refix for will always depend on the current market and whether interest rates are tracking up or down. When the market is tracking down, shorter-term fixes can be beneficial to capitalise on savings quicker, but when rates are rising, a longer-term fix could give you consistency in your payments.

You can also consider shortening the overall term of your loan to pay off in 25 years instead of 30. It does not always mean drastically increasing your repayments; your mortgage adviser can help you run the numbers and investigate.

9: Maximise Extra Income

Bonuses, tax refunds, and unexpected cash boosts are brilliant for reducing interest. But the timing and how you apply them to your mortgage matter. Sometimes, putting a lump sum off the principal is the most beneficial.

Or, putting a lump sum against an offset portion can be the best way. It lets you keep access to the funds while still reducing interest. Used well, it’s a flexible and powerful tool. Again, this is something your mortgage adviser can help you decide on.

10: Don’t Be Afraid To Negotiate

There is almost always wiggle room in the rates that a bank will offer you. Banks generally have unpublished rates and discretionary pricing, but many homeowners either don’t know this or simply don’t ask!

A good mortgage adviser will know when these opportunities exist. They can also give advice on when it might be timely to consider switching banks if you can gain a cash-back offer, sharper pricing or genuine savings. With the right analysis, switching banks can be one of the easiest ways to reduce your total interest bill.
