Affordability Calculator

Applicant information

Enter the number of applicants and any other adults who are financially dependent upon the applicants.

Enter the number of children under the age of 18. Exclude any children who don’t live with the applicants.

Mortgage terms

  • For variable rate products, or products fixed for less than 5 years - you don't need to provide an interest rate as we'll use our default stress rate.
  • For products fixed for 5 years or more - enter the interest rate of the chosen product. We’ll calculate a product specific stress rate to make sure the mortgage remains affordable.
