This simplified offset estimate assumes a steady offset balance and does not model daily balance changes or lender-specific charging cycles.

How an offset account can help

An offset account can reduce the balance that interest is charged on. For example, if your loan balance is $508,000 and your offset balance is $250,000, interest may be charged on a much smaller net amount.

This calculator provides a simplified comparison by applying the offset to the interest-bearing balance. For exact loan projections, use statements from your lender or a full daily interest model.
