Pros
- If your remaining debt is small then it's not costing you much to keep it, and you can use the money in the offset account for emergencies, investments or other expenses.
- If something goes wrong you can easily take money out of your offset account and access it, fast. If you have a separate account with money in it for emergencies, this is less of an issue.
- If you decide to move or buy a second property you can use the funds from your offset account to cover the deposit.
- You could buy a second property and live in it while turning your current home into an investment. This allows you to shift money to the mortgage on your new home and keep paying off the investment (this is advantageous because you can deduct interest expenses on an investment property from your tax).
Cons
- Withdrawing money from your offset account means you pay more interest.
- Even though you're not paying any interest (if your offset amount is the same as your loan amount), you'll still need to make your mortgage repayment each month. You'll keep doing this until the full loan principal amount is repaid.
- If your mortgage has ongoing fees you'll keep paying them as long as you keep the mortgage. This cost could be minimal, but it's something you need to consider.
- Having a mortgage is just one more thing to worry about, and this strategy does require you to pay more attention to your finances.


In this hypothetical scenario, Max has $250,000 left to repay on his mortgage. He also has $250,000 saved in a 100% offset account.
Also consider that offset accounts are guaranteed against bank failure only up to $250,000 – so presumably any money in the offset account above that amount might be lost if your bank goes under. This would seem to be a point in favour of paying off the loan rather than leaving money sitting in an offset account.
This is true, although in most cases a lender going bankrupt will get bought by another institution. I don’t think there’s a case in modern Australia where a lender has gone bankrupt and borrowers with offset accounts have lost out.
But it’s worth keeping in mind all the same.
I have a fixed home loan due to expire in August. I owe $250k but have $120k in offset. I don’t understand why i have only paid 10k off the total amount owing (in the past 12 months). I pay the minimum monthly payment. Should i change to weekly or fortnightly repayments?
Hi Wendy,
We’re unable to provide personal advice, so it’s best to contact your bank directly about your situation.
However we can share that your mortgage repayment is comprised of two parts: one part is the principal (repaying the overall debt) and the other part is interest.
In 12 months, you’ve repaid $10k worth of principal and the rest of your repayments were going towards interest.
Generally, offset accounts are not available to offset the interest in a fixed rate mortgage, so it would be worth checking with your bank to double check you’re getting the benefit here. If you’re not (or even if you are!) you might be able to get a better return on your money by placing it in a high interest savings account.
Hope this helps!
My offset equals my loan, but as interest rates have increased so have my minimum monthly repayments. If the life of the loan hasn’t changed and I’m apparently no longer accruing interest on the loan amount then why would the minimum monthly repayments are increase?
When I asked my bank this question they could not (would not) give me an answer I could understand.
Hi Nico,
We understand how confusing repayments can be but as a comparison site, we’re unable to comment on how your lender works out its repayments. It would still be best to discuss it with them. If their explanation is confusing, don’t hesitate to ask questions or clarification as they’d be happy to break it down for you. You could also talk to a mortgage broker who would be able to work through your situation to see if it’s still the best loan option for you.
All the best,
Rebecca
I have a home loan of $400,000 an offset of $400,000 with redraw amount of $200,000. Will it be beneficial for me to transfer $200,000 from the offset account to home loan account and use the balance $200,000 in the offset account for other investments?
Hi Raj!
Splitting your money from the offset account so that some of it goes to an investment is never discouraged, as long as you know it might give more money in the long-run. :)
You can consult a list of financial advisers to help you decide on this matter based on your situation.
Hope this helps.
Cheers,
Jonathan
