What is an Offset Account?

An offset account is a transaction account linked to your home loan. The balance in this account is offset against your mortgage balance when calculating interest. For example, if you have a $400,000 mortgage and $50,000 in your offset account, you will only be charged interest on $350,000.

How Does an Offset Account Work?

Offset accounts operate much like a regular savings account, allowing you to deposit and withdraw funds at any time. The primary difference is the impact it has on your mortgage interest. By reducing the principal amount on which interest is calculated, you can save significant amounts over the life of your loan.

Types of Offset Accounts

There are generally two types of offset accounts in Australia:

1. 100% Offset Accounts: The full balance in the account is offset against the loan balance. 2. Partial Offset Accounts: Only a portion of the account balance is offset against the loan balance. These are less common but worth noting.

Benefits of an Offset Account

  • Interest Savings: By reducing the principal on which interest is calculated, you can save thousands over the life of your loan.
  • Flexibility: Funds are accessible at any time, providing liquidity for unforeseen expenses.
  • Reduced Loan Term: By saving on interest, more of your repayments go towards reducing the principal, potentially shortening your loan term.

Practical Tips for Using an Offset Account

  • Maximise your Balance: Keep as much money in your offset account as possible. Consider depositing your salary directly into the account.
  • Combine with Budgeting: Use the account to manage your monthly expenses and bills, ensuring any surplus stays in the account to offset your mortgage.
  • Regular Reviews: Regularly review your offset account balance and mortgage statement to ensure you are maximising your interest savings.

Common Mistakes to Avoid

  • Not Maintaining a Sufficient Balance: An offset account is most beneficial when maintained with a substantial balance. Avoid depleting it unless necessary.
  • Choosing the Wrong Loan Type: Not all loans offer offset accounts or may charge higher rates for this feature. Ensure the benefits outweigh any additional costs.
  • Ignoring Fees: Some offset accounts come with fees that can erode your savings. Always check the fine print.
