 Trustindex verifies that the original source of the review is Google. Jeff worked tirelessly to get an equipment finance and overdraft facility in place for our growing business under some very unique & challenging circumstances after we'd previously been pushed away by our banking partner. Working with the DHF team was seamless!

 Trustindex verifies that the original source of the review is Google. The team at Dark Horse Financial were fantastic to deal with when helping me organise finance for my business. Jeff was an absolute dream to work with, no problem or issue was ever too big, and he made everything happen quickly and smoothly. What I thought might take weeks was sorted in a matter of days, and the finance itself was approved within a day. I’ve used plenty of finance companies and lenders before over the years, but the service from Dark Horse Financial is second to none. I’ll definitely be sticking with them from now on. Highly recommend Jeff and the team.

Understanding the Product

How Does a Home Loan Offset Account Work?

A 100% offset account is an everyday transaction or savings account linked to your home loan. Instead of earning interest itself, the balance sitting in it is deducted from your loan balance before your lender works out how much interest to charge you each day. Your scheduled repayment usually doesn't change, so the extra amount that would have gone to interest instead reduces your principal faster.

💰

100% offset

Every dollar in your offset account is deducted from your loan balance before interest is calculated.

📅

Calculated daily

Interest is calculated on your reduced balance each day, so the benefit starts from day one.

🔓

Stays accessible

Unlike extra repayments, your offset balance stays available to withdraw whenever you need it.

Worked Example

🧮 Worked Example

What a Modest Offset Balance Could Save

The loan: A $500,000 home loan over 30 years at 6.24% p.a., with repayments of $3,075.33 a month — the same whether or not an offset account is used.

The offset: Starting with $40,000 in an offset account today, plus $300 a month in ongoing deposits.

The result: Roughly $265,000 saved in interest and the loan paid off about 7 years 2 months sooner — without ever changing the repayment amount.

Suitability

Is an Offset Account Right for You?

An offset account tends to make the most sense when:

✓You keep a meaningful, fairly stable balance in savings or everyday banking
✓You're on a variable rate loan, where full offset accounts are most commonly available
✓You want your savings to keep reducing interest while remaining accessible
✓You'd rather not lock money away in extra repayments you can't easily get back
✓You want to compare how a delayed offset start could affect your interest bill
✓You're weighing an offset account against refinancing or restructuring your loan

FAQ

Frequently Asked Questions

Common questions about home loan offset accounts — answered directly.

What is a home loan offset account?

A 100% offset account is an everyday transaction or savings account linked to your home loan. Every dollar held in it is deducted from your loan balance before interest is calculated each day, so you pay interest on a smaller amount without making extra repayments.

How much can an offset account actually save me?

It depends on your loan balance, interest rate, remaining term and how much you consistently keep in the offset account. As a guide, keeping $40,000 in an offset against a $500,000 loan at 6.24% p.a. over 30 years could save well over $250,000 in interest and cut years off the loan term. Use the calculator above to model your own numbers.

Is my whole offset balance used to reduce interest, or only part of it?

With a full (100%) offset account, the entire balance offsets your loan dollar for dollar. Some lenders offer partial offset accounts where only a percentage of the balance is applied, so always check your loan's product terms. This calculator assumes a 100% offset.

What's the difference between an offset account and making extra repayments?

Extra repayments reduce your loan balance directly and are usually harder to access again. Money in an offset account still reduces the interest you're charged, but stays accessible like a normal transaction account, which suits people who want to keep their savings flexible.

Can I add an offset account to a fixed rate home loan?

Many lenders only offer a full offset account on variable rate loans, or cap how much of a fixed loan balance can be offset. If you're comparing fixed and variable options, ask your broker how offset functionality differs between them.

Does an offset account cost extra?

Some lenders bundle offset accounts into a package rate with an annual fee, while others include them at no extra cost. Whether an offset is worth it depends on that fee compared with the interest savings for your loan size and offset balance.

How accurate are the figures this calculator shows?

This calculator gives an estimate based on the figures you enter, assuming a consistent offset balance and standard principal-and-interest repayments, with interest calculated on the loan balance net of your offset each month. It does not account for rate changes, fees, or lump-sum repayments, so treat it as a guide rather than a formal quote.

Should I speak to someone before opening an offset account?

Yes. Offset accounts, package fees and eligibility vary a lot between lenders, so it's worth talking to a broker who can compare offset-enabled loans across multiple lenders for your situation.
