Using and Interpreting the Calculator

Entering Income

Gross Annual Income

Please enter the customer’s gross annual income before any deductions. Where the customer works more than one job, add both gross incomes together.

Additional / Variable Income

Where 3 years evidence available – 100%

Step 1 - Please input the average of any bonus / commission / overtime earned by the applicant for the last 3 years (reference P60’s / salary cert etc).

Step 2 For car and/or shift allowance, we do not apply an average. Please add the current level of each to the overall variable income number – i.e. what is their car allowance now & what is their shift allowance now. Please note that 3 years evidence of each is still required.

The calculator will take 100% of total variable income, capped at a maximum of 50% of overall basic income per applicant.

Where less than 3 years evidence available – 50%

Please enter a total for all additional / variable income earned in the last year. The calculator will take 50% of the number submitted.
