Refinance Calculator

Our refinance calculator shows whether refinancing at a lower rate saves money after accounting for early repayment charges and new arrangement fees. The break-even point shows how long you need the new loan before saving begins.

Enter your current loan details — balance, rate, remaining term — and the refinancing option details. The calculator shows the monthly payment difference and total interest comparison. Refinancing at a lower rate is most valuable when the outstanding balance is large and significant term remains. Against this saving, weigh early repayment charges on the existing loan and any fees on the new product. If your credit profile has improved since taking the original loan, you may now qualify for a substantially lower rate — a brief soft search with major lenders or through a broker can confirm this without affecting your credit file. For secured loans, refinancing involves full new underwriting including a property valuation.
