Mortgage Affordability Calculator

This calculator will give you a rough idea of affordability, but please remember that we do consider all applications manually, not with automated tools

What income to include:

Car Allowance: 100%
Child Benefit / Tax Credits: 100% of any child benefit your client receives with at least five years left to run
Contractors: For contract workers, enter one-twelfth of their latest self-assessment (SA302), taking into account tax and NI. Or, if applying for our contractor product, please use daily rate x 5 x 46
Overtime: Regular - 50%
Self Employed: One-twelfth of their latest SA302, taking into account tax & NI contributions as monthly income

A few useful tips...

  • Use current figures for expenditure, not future forecasts.
  • You must include all committed and essential outgoings. If there aren't boxes for the types of outgoings you want to include, please group them together under one of the headings available.
  • Generally we don't exceed 4.5x income. If you have an application over this we will consider on a case by case basis.

Shared ownership: for remortgages and cases where the property was built within the last ten years please call us for an affordability assessment

Self build: please contact us for an affordability assessment or complete our self build enquiry form
