Put the examples into your own budget

Use our UK mortgage calculator to compare estimated repayments using your loan amount, interest rate and repayment term. Keep the inputs consistent when comparing options, then change one at a time to see its effect.

If you are planning a purchase, our mortgage affordability calculator can help you explore a starting borrowing estimate. Compare it with your actual household spending; a calculator result is not a lender's approval.

Read the assumptions alongside the result

These articles focus on the UK mortgage market and distinguish the full repayment term from the period covered by a fixed-rate deal. Worked examples explain the rates, fees and repayment assumptions used, so you can see what each comparison includes.

Example rates are not live mortgage offers. Product conditions and personal circumstances affect the options available to you. The guides provide general information; confirm specific terms with your lender or mortgage adviser.
