Key Takeaways

In Australia, managing home loan interest is a priority for many homeowners. One effective way to reduce interest significantly is a mortgage offset account. This feature, offered by many Australian lenders, can significantly reduce the interest paid on a home loan, potentially saving thousands of dollars over the life of the loan. Let’s discuss what an offset account is, its benefits, how it compares to a redraw facility, its considerations, and how to get started.

What is a Mortgage Offset Account?

A home loan offset account is a transaction account linked to your home loan. The balance in this account is used to offset the amount of your loan on which interest is calculated. For example, if you have a home loan balance of $400,000 and $50,000 in your offset account, interest is charged only on $350,000. This reduction in the loan balance leads to lower interest payments.

How Mortgage Offset Accounts Work

How does a mortgage offset save money? Interest on home loans in Australia is typically calculated daily. The more money you have in your offset account, the less interest you pay. Since the interest saved in a home loan offset account is not taxable, it can be more beneficial than earning interest in a regular savings account, where the earnings are subject to tax.

Most offset accounts are linked to variable-rate home loans. Some lenders also offer split loans, where part of the loan is fixed and part is variable, allowing you to have an offset account on the variable portion.

Benefits of Mortgage Offset Accounts

1. Interest Savings

The primary advantage of an offset account is the reduction in interest payments. For instance, if you have a $500,000 loan and $50,000 in your offset account, interest is calculated on $450,000. Over the life of a 30-year loan, this can result in significant savings. 

2. Flexibility and Accessibility

An offset account functions like a regular bank account. You can deposit your salary, pay bills, and withdraw funds as needed. This flexibility makes it easier to manage your finances while reducing your mortgage interest. 

3. Tax Efficiency

Unlike interest earned in a standard savings account, the interest saved through an offset account is not taxable. This makes it a more tax-efficient way to reduce your mortgage balance. 

4. Potential to Pay Off Your Loan Sooner

By reducing the interest charged on your loan, more of your regular repayments go towards paying down the principal. This can shorten the term of your loan, helping you become mortgage-free sooner. 

Mortgage Offset vs. Redraw Facility

While both offset accounts and redraw facilities can reduce the interest paid on a home loan, they operate differently:

FeatureOffset AccountRedraw Facility
Account TypeSeparate transaction accountFeature within the home loan
Access to FundsInstant accessMay require processing time
Interest CalculationBased on loan balance minus offset balanceBased on loan balance minus extra repayments
Tax ImplicationsInterest saved is not taxableInterest saved may be taxable
FlexibilityHigh, funds can be used for any purposeLimited, funds are tied to extra repayments

Is a Mortgage Offset Better Than a Redraw Facility?

Whether a mortgage offset account is better than a redraw facility depends on your financial needs and how you manage your money. An offset account offers more flexibility, acting like a regular transaction account where you can deposit your income and access funds instantly. In contrast, a redraw facility only allows you to access extra repayments you’ve made on your loan.

For borrowers who value easy access to their funds and want a simple way to reduce interest while managing their cash flow, an offset account is often the better choice. However, if you’re confident you won’t need immediate access to your extra repayments and prefer to focus on reducing your loan balance, a redraw facility can still offer strong interest mortgage savings.

Strategies to Maximise Mortgage Offset Benefits

To fully leverage the advantages of a mortgage offset account, consider the following strategies:

1. Deposit Your Salary into the Offset Account

By having your salary paid directly into your offset account, you increase the balance, thereby reducing the interest charged on your loan. 

2. Use an Interest-Free Credit Card for Everyday Transactions

If you can manage to stick to a budget and have good habits with credit cards, you can maximise your interest saved by combining your offset with using an interest-free credit card for daily expenses.

3. Maintain a Healthy Balance

The more money you keep in your offset account, the greater the reduction in interest payments. Aim to maintain a balance that is substantial relative to your loan size.

Who Benefits Most from Mortgage Offset Accounts?

Mortgage offset accounts are particularly beneficial for:

  • Homeowners with Variable-Rate Loans: Since offset accounts are typically linked to variable-rate loans, homeowners with these types of loans can take full advantage of the interest savings.
  • Those Who Want To Pay Off Their Mortgage Quickly: Those aiming to pay off their home loans much more quickly can benefit from a mortgage offset account.

  • Individuals with Regular Income: Those who receive regular income, such as salaried employees, can maintain a higher balance in their offset account, leading to greater interest savings.

  • Homeowners Seeking Tax-Efficient Savings: Since the interest saved through an offset account is not taxable, it is a tax-efficient way to reduce mortgage debt.

Can You Access Funds Easily with an Offset Account?

Yes, one of the key advantages of an offset account is the ease of access to your funds. You can withdraw money, pay bills, and make purchases just like with a regular bank account. This flexibility makes it an attractive option for managing your finances while reducing mortgage interest.

How to Get Started

If you’re interested in opening a mortgage offset account or refinancing your current home loan to include one, here are the steps:

  1. Review Your Current Loan: Check if your existing home loan offers an offset feature or if you need to refinance to a new product.

  2. Speak with a Mortgage Broker: A qualified mortgage broker, such as the team at Dark Horse Financial, can help you compare loan products and negotiate better terms.

  3. Plan Your Cash Flow: Set up your salary to be paid directly into your offset account and use it for everyday expenses.

  4. Track Your Savings: Many lenders provide offset calculators and tracking tools so you can monitor your interest savings in real time.
