This calculator is for illustrative purposes only and does not constitute financial advice. Results are approximate and assume a fixed interest rate throughout the mortgage term. Your actual savings may vary depending on your lender’s terms and conditions. Please check with your mortgage provider before making overpayments — some lenders impose early repayment charges. Always seek independent financial advice for decisions about your mortgage.
