About UK Mortgage Calculators

What We Do

UK Mortgage Calculators provides free, instant mortgage calculation tools for UK homebuyers, first-time buyers, landlords, and anyone looking to understand their mortgage options. Our calculators cover monthly repayments, stamp duty, affordability, buy-to-let yields, remortgaging, and overpayments.

Our Approach

All calculations happen instantly in your browser — we never store or transmit the figures you enter. We use up-to-date UK tax rates and lending rules, reviewed regularly to keep pace with HMRC and industry changes.

We believe that understanding your mortgage numbers shouldn’t require an appointment with a broker. Our tools give you a clear starting point before you seek professional advice.

Important Notice

UK Mortgage Calculators is not regulated by the Financial Conduct Authority (FCA). Our tools provide estimates for illustrative purposes only and do not constitute financial advice. We always recommend consulting an FCA-regulated mortgage adviser before making any financial decision.
