# Contribution Margin Ratio

Also known as the dollar contribution per unit, the contribution margin ratio represents the incremental money generated for every unit, whether it’s a product or commodity.

The contribution margin ratio is calculated using a simple formula. The variable cost per unit is subtracted from the selling price per unit equal to the contribution margin ratio. The use of this calculation goes a long way, but the main purpose behind it is to see the profitability of products in the business. For example, if a product takes 10 percent of the workforce and energy of your business but only brings in 2 percent of the profits, the contribution margin ratio is the way to know about this.

While coming up with the contribution margin ratio of certain products might be tough – revealing if it’s worthy of your operations is a big helper for the growth of any business.
