A free, independent UK mortgage calculator

Mortgage Cost Checker helps UK residents understand capital-and-interest repayment mortgages. You can calculate one mortgage, compare two products, or estimate how much you might borrow. Every calculation runs in your browser, and the figures you enter never leave it.

Results are estimates and general information only, not financial advice or a lender quote. Check the full terms with the lender before you decide.
