What is a Mortgage Offset Accounts and How Can it Save More Money on Your Mortgage


How much do you know about offset accounts?

Let us first begin with a brief explanation and then move ahead with the details. Offset accounts are a type of savings or transaction account that is connected to an eligible home or investment loan. Mortgage offset accounts can be linked either to a fixed or variable rate loan. Having an offset account against your mortgage is a plus factor since it aids in reducing the entire interest on the home loan, thus paying off your mortgage faster.

Offset accounts work by deducting the money in your savings account against the balance of your home loan. For example, your home loan is left with a balance amount of $180,000 and you have savings worth $20,000. Now, if you choose to have 100% of the savings amount offset, then the entire $20,000 is deducted from the mortgage amount, thus leaving with a home loan balance of $160,000.

On the contrary, you can also choose to have a partial offset account like of 30%. If the second case applies then your interest will be payable on a loan amount of $174,000 after deducting the $6000 from the offset account.

So, if a homeowner is aged 25 years and possesses a home loan worth $350,000 for another 30 years, he/she could easily cut off that amount by 6 years and a half if he/she can maintain a savings balance of $50,000 in his/her offset account. So, rather than waiting 30 years to complete the loan, the homeowner will instead pay it all off in 23 years instead. Furthermore, this will also save him/her a lot of money on the monthly interest payments that is charged on the loan.

Types of Offset Accounts

Offset accounts are of two types. They are-

  • Balance offset account; and
  • Interest offset account

The first one, balance offset accounts, is the most common account. In case of a balance offset account, the interest payable on a mortgage is deducted from the savings amount. The deductions can be partial or full as per your choice.

Interest offset accounts, on the other hand, deduct the interest payable on a mortgage by the interest earned on the offset account. The interest earned on your savings is considerably lesser than the interest rate on a mortgage, which makes the choice less favorable and common.

As a homeowner, you must be advised that it is only variable rate loans that have the option of a 100% offset account. In case of split loans, homeowners are allowed to have an offset account that can help them reduce the amount of the variable portion of the loan.

Advantages of an offset Account

Other than the feature of reducing your loan term and saving interest, an offset account has several other advantages if chosen well. Here are some advantages to look forward to.

  • You can easily manage an offset account. All you require to do is link your standard savings account or transaction account, where you receive your salary, as an offset account to your loan.
