Calculations are for illustrative purposes only. They may not be 100% accurate for the following reasons:
- Calculations may contain rounding errors.
- Lenders may calculate interest using differing methods.
- There are many ways of calculating offset mortgage benefits. The method used in this tool is to calculate the payment as a repayment mortgage and then subtract the interest that has been charged on the loan amount equal to the offset amount.
- There may be coding errors in this tool.

For these reasons, and not limited to these reasons, you should always seek professional financial advice before entering into any financial arrangements. This tool does NOT provide any form of financial advice.
