In the realm of Australian real estate financing, savvy homeowners are constantly seeking ways to optimize their mortgage strategies. One powerful tool that has gained prominence is the Mortgage Offset Account. In this blog post, we’ll delve into the intricacies of this financial instrument, exploring what it is, how it works, and the myriad benefits it offers to homeowners.

What is an Offset Account?

At its core, a mortgage offset account is a financial product intricately linked to your mortgage. It functions as a transaction account that is directly connected to your home loan. The balance in this account is offset against the outstanding loan amount, potentially saving homeowners thousands of dollars over the life of their mortgage.

Why do People Use Offset Accounts?

Offset accounts have become a popular choice among Australian homeowners for several reasons. These include the ability to reduce interest payments, accelerate loan repayment, and provide a flexible and accessible way to manage finances. In the next sections, we’ll explore these reasons in detail, shedding light on why an offset account might be the ideal financial tool for you.

How Does an Offset Account Work?

Understanding the mechanics of an offset account is crucial for maximizing its benefits. 

Accessing funds from your offset account is as simple as using a debit card or withdrawing cash from an ATM, much like a standard transaction account. Maintaining a balance in your offset account works to curtail your interest obligations.

Many homeowners opt to have their salaries directly deposited into their offset account, treating it as they would a regular transaction account. Another option is utilizing the offset account as a dedicated fund for upcoming expenses like a vacation, a vehicle upgrade, or home renovations. It’s essential to note, however, that a lower balance in the account translates to higher interest charges on the principal of your mortgage.

Similar to a redraw facility, the funds in your offset account can also serve for emergencies, such as medical procedures and bills. Moreover, akin to a standard transaction account, these funds are readily available for immediate use when needed.

Consider this scenario as an example: if you maintain a balance of $10,000 in your offset account and your existing home loan stands at $500,000, the funds in your offset account effectively mean you’re only accruing interest on your mortgage balance minus the offset amount. Put simply, you’ll be charged interest on a reduced $490,000 loan balance instead of the full $500,000.

Full vs Partial Offset Accounts

The two types of offset accounts are:

1.Full offset accounts:

With this type, you can offset the entirety of your home loan principal against 100% of the funds in the account. Consequently, it is generally advisable to maintain a substantial account balance.

2. Partial offset accounts:

This option limits its advantages to a portion of the funds in your account. Expanding upon the earlier scenario, a partial offset might utilize, for example, 25% of your $60,000 account balance. In this case, your $800,000 home loan principal would be offset by $15,000, resulting in interest being charged on only $785,000.

3 Key Benefits of an Offset Account

Delving deeper, we’ll uncover three key advantages of incorporating an offset account into your mortgage strategy. From interest savings to expedited loan repayment and improved financial flexibility, these benefits will showcase why an offset account is more than just a financial accessory—it’s a strategic asset for homeowners.

1. Minimize your interest repayments

Offset accounts offer a way to decrease the interest paid on your mortgage by offsetting your savings against your home loan balance. 

For instance, if you have a $500,000 home loan and maintain a $20,000 balance in your offset account, your interest will be calculated based on your home loan balance minus your savings balance, resulting in an effective balance of $480,000. Essentially, this means your interest is computed as if you’ve already repaid $20,000 of your home loan, while still retaining access to the money if needed. 

Many homeowners choose to keep their emergency or rainy-day savings in their offset accounts.

2. Effectively manage your budget

Your offset account can serve as a valuable tool for budget management, especially with lenders offering multiple offset accounts against a single home loan. 

Modern lending practices allow customers to distribute their offset savings across multiple accounts. Some lenders provide a 100% offset across up to 6 accounts for fixed and variable loans, enabling various savings categories like splurge funds, emergency funds, school fee funds, holiday funds, and grocery funds to offset home loan interest.

3. Optimize the returns on your money

While it’s prudent to have cash readily available in the bank, traditional savings accounts may lose value due to the gap between interest rates and inflation. If your home loan interest rate surpasses the rate earned on a savings account, your money would work more efficiently for you in an offset account. This approach ensures that you maintain easy access to your funds while simultaneously minimizing the overall interest paid on your home loan.

How to Set Up an Offset Account

Setting up an offset account is a straightforward process, yet it requires careful considration. In this section, we’ll guide you through the steps involved, offering practical tips on choosing the right offset account, linking it to your mortgage, and maximizing its potential to suit your financial goals.

  • Offset accounts can be linked with eligible variable rate home loans.
  • Fixed-rate loans cannot be connected to an offset account until the fixed-rate term ends, at which point the loan transitions to a variable interest rate.
  • An eligible transaction account, like the NAB Classic Banking account, is required.
  • The individuals identified on the offset account must match those listed on the home loan.

What is the Difference Between a Loan Account and an Offset Account?

In Australia, a loan account and an offset account are two distinct financial tools, typically associated with home loans. Here are the key differences between the two:

Loan Account:

  • A loan account is the primary account that holds the borrowed funds, such as a mortgage for purchasing a home.
  • It is used to track the principal amount borrowed, and interest is charged on this principal.
  • Repayments are made into the loan account to reduce the outstanding balance over time.
  • The interest on the loan is calculated based on the remaining balance of the loan.


Offset Account:

  • An offset account is a linked transaction account connected to the home loan.
  • Instead of earning interest, the funds in the offset account are offset against the outstanding balance of the loan.
  • The balance in the offset account is subtracted from the loan balance when calculating interest. For example, if you have a $300,000 loan and $50,000 in your offset account, you only pay interest on $250,000.
  • It can help borrowers save on interest payments and potentially pay off their loan faster.


While a loan account is the primary account where the borrowed funds and repayments are managed, an offset account is a separate account linked to the loan, and the balance in the offset account is used to offset the interest payable on the loan. This can be a valuable strategy for borrowers looking to minimize interest costs and accelerate the repayment of their home loan.

What is the Difference Between Offset and Standard Mortgage?

An Offset Mortgage operates much like a Standard Mortgage, with the notable addition of an extra feature—a connected Offset Saver savings account. Any funds deposited into the savings account are automatically subtracted from the mortgage amount, reducing the balance on which interest is calculated.

Things to Consider with Offset Accounts

While offset accounts offer numerous advantages, it’s essential to consider various factors before incorporating them into your financial strategy. 

  • Account Fees: Certain offset accounts come with associated management fees.
  • Elevated interest rates: Mortgages featuring an offset account may carry higher associated interest rates.
  • Minimum balance requirements: In order to rationalize the account fees and elevated interest rates, it may be necessary to uphold a substantial balance in your offset account, a prospect that may not be viable for all homeowners.


It’s evident that Mortgage Offset Accounts in Australia is a game-changer financial tool for homeowners. By understanding how offset accounts work and leveraging their benefits, you can potentially save money, expedite loan repayment, and gain greater financial control.
