Without overpayments
With overpayments
Assumes a fixed interest rate for the whole remaining term. Some mortgage deals cap the amount you can overpay each year (often 10% of the balance) without an early repayment charge - check your mortgage terms before overpaying.
Why small overpayments add up
Every pound you overpay reduces the balance interest is calculated on for the rest of the mortgage, not just that month - so the saving compounds over the remaining term. That's why even a modest, sustainable monthly overpayment tends to save more in total interest than its simple multiplication would suggest.
