How much could an offset account save you?

Estimate your monthly repayment and see how maintaining an average balance in an offset account could reduce the interest charged on your loan.

See the impact of your offset

Enter your loan details and the average balance you expect to keep in your offset account. Your repayment is calculated on the full loan amount, while interest is calculated on the loan balance less the offset balance.

  • See your estimated monthly repayment based on the full loan amount
  • Compare total interest with and without an offset
  • See the estimated interest savings from your average offset balance
  • Compare the loan balance over time with two amortisation lines

Loan repayments are only one part of choosing the right finance. We can also look at your loan structure, rate, offset and refinancing options.

Estimated loan balance over time

The repayment remains the same in both scenarios. The offset reduces the balance on which interest is calculated, so more of each repayment reduces principal.

Without offset With offset
An amortisation comparison chart showing the estimated loan balance over time with and without an average offset account balance.
This calculator provides an estimate only and is not credit advice. It assumes a constant interest rate, monthly compounding, repayments made at the end of each month (monthly in arrears), and that the entered average offset balance is maintained throughout the calculation. Interest is calculated on the greater of the loan balance less the offset balance or zero. Fees, rate changes, redraws and lender-specific rounding conventions are not included.
