Mortgage repayment calculator

Use our mortgage repayment calculator to work out how much your monthly mortgage payments will be based on loan size, term, interest rate and fees.

If you're comparing mortgage deals, it's important to understand what seemingly small differences in interest rates and fees can mean for your monthly repayments.

Our mortgage repayment calculator shows you how much a deal will cost each month based on how much you're borrowing, the interest rate and fees of the deal, and the term of the mortgage (how long you'll take to pay it off).

For expert help with every step of the mortgage process, from finding the best deal for you to submitting an application, call Which? Mortgage Advisers on 0800 197 8461.
