Track your mortgage overpayments and see exactly how much interest you save

Building a mortgage overpayment tracker in Excel is a smart goal, but the math can trip up even confident spreadsheet users.

Your overpayments change the principal, so you need a running balance that recalculates after each entry. Start with a simple amortization table that recalculates the remaining balance after each payment.
