9 Smart Ways to Use an Offset Account to Cut Mortgage Rates

With the rising cost of living, many Australian borrowers are considering an offset account as part of a smarter repayment strategy. Why? Because they’re simple, effective, flexible and have the potential to save you tens of thousands of dollars over the life of a loan (without having to make any big sacrifices).

But this raises some questions, including:

• What is an offset account?
• How does it work?
• What are some mortgage offset account benefits?
• How can you decide whether this is right for you?

What is an Offset Account?

First of all, what is an offset account? It’s a savings or transaction account that’s linked to your home loan. Instead of earning interest like a traditional savings account, the balance in your account is “offset” daily against your loan balance, reducing the amount of interest charged.

For example, if you have a home loan of $500,000 and $30,000 in your offset, your lender will only calculate interest on $470,000. The more you have in your account, the less interest you’ll pay over time. It’s one of the simplest ways to use your existing savings to reduce loan costs without locking those funds away.

How an Offset Account Works

Many mortgage-holders are surprised to learn that the interest on a home loan is calculated daily, not just once per month. Every day, the lender looks at the balance of your loan and calculates the interest owing for that day. Then once a month, the combined total of all those daily interest calculations is charged to your loan.

Why is this relevant? Because the amount of money in your offset bank account will likely change from day to day. And every little bit helps. For example, if your salary is deposited into your account, the balance will go up and your interest charge will go down (even if only for a few days).

You can also use it as a home loan interest savings account. By depositing all of your savings into the account, your interest could be reduced, but you’ve still got ready access to your savings when and if you need them.

Mortgage Offset Account Benefits

What are the benefits of having an offset loan feature? It can help with:

• Reducing the amount of interest you’re charged over the life of the loan.
• Paying off your home loan faster.
• Using your savings to achieve measurable results, without losing immediate access to them.
• Investors who are looking to structure their debt more effectively.

While this may seem like only small savings on a month-to-month basis, it can add up to an impressive amount over the life of the loan.

9 Smart Ways to Use an Offset Account

How can you use an offset account so that you maximise the potential benefits?

1. Deposit Your Salary in Your Offset Account

Ensure that routine deposits are paid into the account. This is a simple and effective way to immediately reduce interest. You can still move money out, as needed, but you’re saving on interest for every day you have those extra funds in your account.

2. Use It As Your Everyday Bank Account

Don’t just think of it as a savings account (where extra money goes to sit). Every extra dollar in the account is beneficial, so using it for your everyday expenses can maximise your offset. This helps you avoid leaving idle cash sitting in low-interest everyday accounts.

3. Use It Instead of Making Additional Repayments

Some borrowers may be tempted to pay any additional savings directly into their home loan. While this can be a useful tactic for paying off a mortgage faster, it can be difficult to access those funds if they’re needed in the future. Keeping savings in your offset reduces interest, but your money remains accessible.

4. Build an Emergency Buffer

Many Australians use their credit card as a buffer for personal expenses. While this can be useful for things like direct debits, it can also lead to unnecessary interest charges.

By building an emergency buffer (such as 3-6 months of living expenses) into your offset balance, you can reduce your reliance on credit cards, while also reducing your home loan interest.

5. Put Your Lump Sum Savings to Work

According to a report from ING, the average Australian has over $22,000 in “rainy-day” savings. Additionally, many may have “short-term” savings for upcoming holidays, car purchases or home renovations. Putting these funds into an offset savings account can keep more of your money working for you, even while it’s not being used.

6. Use Tax Refunds or Bonuses Strategically

When used intentionally, annual tax refunds or end-of-year bonuses can be a great way to reduce interest charges. By depositing these lump sums into your offset, you maximise the interest reduction effect (even if the funds are used for something else shortly afterwards).

7. Combine with Budgeting Systems

Some lenders offer multiple offset-linked accounts. These can act as an effective budgeting system, allowing you to allocate funds for bills, everyday spending and future savings. The combined total is used for your offset, but there’s no risk of you accidentally tapping into your savings while doing the weekly shop.

8. Access Potential Tax Benefits

For property investors, keeping funds in an account with an offset function can reduce interest while still keeping the original loan structure intact. This can be useful when loan interest is tax deductible, as the extra funds are being held in the offset rather than being repaid into the loan.

Remember that tax outcomes always depend on individual circumstances, so it’s a good idea to talk to a qualified accountant before making decisions with potential tax implications.

9. Strategically Reduce Loan Term

By consistently reducing your interest charges, you could begin to pay down the principal portion of your loan faster. Over time, this could help to reduce the length of your loan term, enabling you to be mortgage-free faster.

Offset Account vs Other Loan Features

It’s easy to confuse an offset account with a redraw facility, but they serve slightly different purposes.

• An offset account is a separate everyday account that reduces loan interest based on its balance. The funds remain accessible at all times.
• A redraw facility lets you withdraw any extra repayments you’ve made on your loan – but funds are not always available instantly, and access might be limited.

While both help reduce loan interest, offset accounts are better suited to borrowers who want flexibility and quick access to their savings or investors who want to protect tax deductibility when offsetting investment debt. Redraws may be a better fit for borrowers looking to “set and forget” with their extra repayments.

Is an Offset Account Right for You?

If you regularly maintain savings, have a consistent income or hold investment loans, a mortgage with an offset feature could be a valuable financial tool. It’s especially useful for:

• Professionals who receive regular pay and want to park funds before bills are paid.
• Savers who want their money working harder without sacrificing access.
• Homeowners focused on reducing loan interest over the long term.
• Investors who want to maintain access to cash without affecting tax-deductible interest.
• Families managing multiple expenses.

However, it’s important to note that this loan feature may be coupled with a higher interest rate or added fees. For this reason, it may not be the best choice for some borrowers.

Get More From Your Home Loan With the Right Strategy

An offset account can be incredibly valuable, but only when used correctly. How you choose to use your account can have a significant impact on how much money you can potentially save over the life of the loan.

If you’re wondering whether a loan with an offset account could help reduce your mortgage costs, the best thing to do is speak with an experienced mortgage broker. A broker can assess your current financial situation, compare loan products and make recommendations on which lenders will best support your future goals.
