About the UK Mortgage Overpayment Calculator
Use this calculator to estimate how regular monthly overpayments could reduce the interest you pay and shorten your remaining mortgage term.
Enter your current mortgage balance, interest rate, remaining term and planned monthly overpayment. The calculator works out the standard monthly repayment first, then models repayment with the overpayment included.
Results are estimates only. Actual overpayment limits, charges and product terms depend on your lender. For a basic monthly repayment estimate, try the Mortgage Repayment Calculator.
