An offset account can help reduce the interest charged on your home loan while keeping your savings accessible. For many borrowers, it can be a simple way to manage money more effectively and potentially pay down a loan sooner.

For many homeowners, reducing interest is one of the most effective ways to get ahead on a home loan. One feature that may help is an offset account.
An offset account is a transaction account linked to your home loan. Instead of earning interest like a normal savings account, the money held in the offset account is used to reduce the loan balance that interest is calculated on.
This means your savings can continue to remain accessible while helping reduce the amount of interest charged on your mortgage.
What Is an Offset Account?
An offset account works like a regular everyday account, but it is connected to your home loan.
The balance in the offset account is offset against your loan balance when interest is calculated.
For example, if your home loan balance is $500,000 and you have $30,000 in an offset account, interest may only be calculated on $470,000.
You still owe the full loan amount, but the interest calculation is reduced by the amount sitting in the offset account.
Why an Offset Account Can Be Useful
An offset account can be useful because it allows your money to work harder while still giving you access to it.
Instead of keeping savings in a separate account earning interest, some borrowers prefer to keep funds in an offset account because it may reduce home loan interest.
Potential benefits include:
- Reducing interest charged on the home loan
- Helping more of each repayment go toward the loan principal
- Keeping funds accessible for everyday use
- Supporting better cash flow management
- Potentially reducing the overall loan term
- Helping manage emergency savings while still lowering interest
For borrowers with regular savings, surplus income, or business cash flow, an offset account can be a practical tool.
Offset Account Example
Imagine you have a home loan balance of $600,000.
If you keep $50,000 in your offset account, the lender may calculate interest on $550,000 instead of $600,000.
That difference can reduce the interest charged over time. If you maintain a strong offset balance for a long period, the savings can become significant.
The larger the balance in the offset account, and the longer it stays there, the greater the potential interest reduction.
Offset Account vs Redraw Facility
Offset accounts and redraw facilities can both help reduce interest, but they work differently.
An offset account is usually a separate transaction account linked to the loan. You can generally deposit income, pay bills, and withdraw funds from it like a normal bank account.
A redraw facility allows you to access extra repayments you have made into the loan, subject to lender rules. Some redraw facilities may have restrictions, processing times, or limits on how funds can be accessed.
The key difference is access and structure.
An offset account may be more flexible for everyday money management, while redraw may be more suitable for borrowers who want to make extra repayments but do not need frequent access to the funds.
Who Might Benefit From an Offset Account?
An offset account may be useful for different types of borrowers, including:
- Homeowners with savings
- Borrowers who keep emergency funds
- People who receive regular income
- Investors managing rental income
- Self-employed borrowers managing cash flow
- Borrowers planning future expenses
- Homeowners wanting flexibility while reducing interest
For example, a self-employed borrower may use an offset account to hold funds for tax, business expenses, or irregular income periods while still reducing interest on the linked home loan.
How to Use an Offset Account Effectively
An offset account can be more effective when used consistently.
Some borrowers choose to have their salary or business income paid directly into the offset account. Everyday expenses can then be paid from the same account, while the remaining balance continues to reduce interest.
Other borrowers use the offset account to hold savings, emergency funds, or money set aside for future expenses.
Ways to use an offset account may include:
- Depositing salary or income into the offset account
- Keeping savings in the offset instead of a separate savings account
- Using the account for regular expenses
- Holding emergency funds
- Saving for future renovations or investment plans
- Keeping tax or business funds accessible
The goal is to maximise the balance in the offset account for as long as practical.
Things to Check Before Choosing an Offset Account
Not every offset account works the same way. Before choosing a loan with an offset feature, borrowers should check how the account is structured.
Important questions include:
- Is it a 100% offset account?
- Does it link to a variable loan only?
- Are there monthly or annual fees?
- Can the offset be linked to multiple loan splits?
- Is the account easy to access?
- Does the feature suit your repayment strategy?
- Would the interest savings outweigh any fees?
Some offset accounts may only apply to specific loan products, loan splits, or variable-rate loans. It is worth checking the loan terms carefully before applying.
