What is Contribution Analysis?
Contribution analysis is used in estimating how direct and variable costs of a product affect the net income of a company. The study addresses the issue of identifying simple or overhead costs related to several production projects. Contribution analysis aids a company in evaluating how individual business lines or products are performing, by comparing their contribution margin dollars and percentage. Direct and variable costs incurred during the manufacturing process are subtracted from revenue to arrive at contribution margin. This is, therefore, a very crucial procedure in the growth of a business.

Contribution margin formula
The formula for contribution margin dollars per unit is:
(Total revenue – variable costs) / # of units sold
For example, a company sells 10,000 shoes for total revenue of $500,000 with the cost of good sold of $250,000, and shipping & labor expense of $200,000.
The contribution margin per shoe is ($500,000 – $250,000 – $200,000) / 10,000
Contribution = $5.00 per shoe
