Frequently asked questions
How much can I save by overpaying my mortgage?
The amount you save depends on your outstanding balance, interest rate, and how much you overpay each month. On a typical £200,000 mortgage at 4.5% with 22 years remaining, overpaying just £200/month can save over £20,000 in interest and cut more than 5 years off your term.
Is it always a good idea to overpay your mortgage?
Overpaying can be an excellent strategy, but check for early repayment charges first. Most lenders allow overpayments of up to 10% of the outstanding balance per year without penalty. You should also ensure you have an emergency fund before overpaying.
How is the mortgage overpayment calculation done?
The calculator uses standard mortgage amortisation to work out your current monthly payment, then recalculates with your chosen overpayment added. It compares total interest paid under both scenarios to show your savings, and calculates your new payoff date.
