An offset account can be a powerful tool for reducing the interest you pay on your home loan.
But despite the benefits, there are situations where an offset may not be the most cost-effective choice.
Let’s break down when it might not work in your favour.
1️⃣ Low or No Savings
Offset accounts only save interest when you keep money in them.
If your balance is usually low, the interest savings will be minimal.
In this case, a basic home loan without an offset — often with lower fees or a lower rate — may actually be cheaper.
2️⃣ Higher Fees or Higher Interest Rates
Many lenders charge:
- A slightly higher rate, or
- Additional account fees,
for loans that include an offset account.
If you don’t hold a meaningful amount of savings, the higher cost could outweigh any benefit.
3️⃣ Offset Linked to an Investment Property
If you still have an owner-occupied (OO) loan, your offset should usually sit against that loan first — because OO loan interest is not tax-deductible.
Using an offset for an investment loan only tends to make sense when:
- Your home loan is already paid off, or
- You need a flexible place to park cash without affecting tax deductibility.
4️⃣ Short Loan Terms or Frequent Refinancing
If you expect to:
- Sell the property,
- Refinance, or
- Pay off the loan early,
you might not keep the loan long enough to benefit from the offset — especially given the extra fees or higher rate.
5️⃣ Not Managing Cash Flow Through the Offset
To maximise savings, you need to:
- Put your salary into the offset, and
- Spend directly from it,
- Keeping money in there as long as possible.
If you don’t use the account this way, the benefit drops significantly.
A Good Mortgage Broker Makes a Difference
