MortgageLens is a free, open mortgage calculator built for UK homebuyers and property investors. We help you understand exactly what your monthly repayments will be, how much interest you'll pay over the life of your loan, and how small changes to your deposit, term, or rate can make a real difference.
Why we built it
Most mortgage calculators gate their results behind contact forms. You enter your details, hit calculate, and get asked for your phone number before seeing anything useful. We do it differently — you get your answers immediately, with no sign-up required.
Our promise
Calculator results are never gated behind forms. We only collect personal information when you choose to use a feature that requires it (such as our contact form, mortgage report, or broker enquiry form), and we never sell your data. See our Privacy Policy for the full picture.

Our data
We use real data from trusted UK government sources. Property prices come from HM Land Registry, and interest rate data is sourced from the Bank of England. All calculations use current UK stamp duty thresholds and tax rules.

Important
MortgageLens is an information tool, not a financial adviser. Our calculations are estimates based on the figures you provide. Actual mortgage offers depend on your credit history, income, lender criteria, and other factors. Always speak to a qualified mortgage adviser before making financial decisions.
