Mortgage Term Calculator

The length of your mortgage term has a big effect on both your monthly payments and how much interest you pay overall. Here's how to think it through.

A longer term makes monthly payments more manageable, a shorter one clears the debt sooner and costs less overall. Lenders also consider your age at the end of the term.

30 years£1,266.71£206,017
35 years£1,183.14£246,920

Choosing 35 years over 20 lowers the monthly payment by £398.48 but costs about £117,330 more in interest over the life of the mortgage.
