This tool does the sum a mortgage illustration buries in small print: what a given loan, term and rate actually costs you month to month, and over the full life of the mortgage. Its main limitation is that it assumes one fixed rate for the entire term — in reality you'll likely remortgage every two to five years, so treat the total interest figure as illustrative rather than a prediction.

This calculator is illustrative only and does not constitute financial advice. Always confirm figures with a lender, broker or HMRC before making a decision.
