Mortgage Offset Calculator

An offset account is one of the most effective tools for reducing the interest you pay on your home loan.

Whether you’re a first-time buyer, refinancing, or growing a property portfolio, understanding how offset works can help you pay off your mortgage faster and save money in the long run.

Use our mortgage offset calculator below to estimate your potential savings and see how much faster you could own your home just by keeping extra cash in an offset account.

What Is an Offset Account?

An offset account is a transaction account linked to your home loan. Instead of earning interest like a regular savings account, the balance in your offset account is “offset” daily against your loan balance—reducing the amount of interest you’re charged.

For example, if your home loan balance is $500,000 and you have $30,000 in your offset account, you’ll only be charged interest on $470,000. This simple strategy can significantly reduce your interest charges and shorten your loan term, without changing your lifestyle or making extra repayments.

If you’re exploring how to structure your loan or you’re comparing features, try our home loan offset calculator to see the potential impact of offset on your financial strategy.

It’s an excellent tool if you’re considering refinancing or want to understand how your savings could work harder for you.

Who Should Consider an Offset Account?

Offset accounts are ideal for:

  • First home buyers wanting flexibility and long-term savings
  • Investors looking to reduce interest while keeping funds accessible
  • Homeowners planning to refinance to a more feature-rich loan
  • SMSF clients needing flexible structures for long-term property strategies

If you’re unsure how offset compares to other features like redraw facilities, speak to one of our home loan refinance brokers or your SMSF accountant on the Gold Coast for tailored advice.
