Frequently Asked Questions

Interest is charged on your outstanding loan balance. Money in an offset account is treated as reducing that balance for interest calculations (up to the principal), lowering interest each period.

Both reduce interest. Extra repayments permanently reduce principal; offset keeps funds accessible. The best choice depends on your need for liquidity, rates, and lender rules.

The calculator supports weekly/fortnightly/monthly payments. For the timeline chart and offset compounding, we simulate monthly with an equivalent monthly payment for clarity.
