Contribution Margin is a financial metric that measures the amount of money left over after covering variable costs. It's the amount of money that contributes towards covering fixed costs and generating a profit.
In simple terms, Contribution Margin is the difference between revenue and variable costs. It's expressed as a percentage or a dollar amount.
Contribution Margin is an essential metric for ecommerce companies for several reasons:
Contribution Margin is calculated using the following formula:
Contribution Margin = Revenue - COGS - Commissions - Paid Marketing Spend
The contribution margin can be expressed as a percentage, by dividing the contribution margin by revenue:
Contribution Margin Percentage = (Contribution Margin / Revenue) x 100
Suppose an ecommerce company sells a product for $100. The variable cost per unit is $60. Therefore, the Contribution Margin per unit is $40 ($100 - $60). The Contribution Margin percentage is 40% ($40 / $100 x 100).
