cm ratio formula

As mentioned above, contribution margin refers to the difference between sales revenue and variable costs of producing goods or services. This resulting margin indicates the amount of money available with your business to pay for its fixed expenses and earn profit. In other words, contribution margin per unit is the amount of money that each unit of your product generates to pay for the fixed cost. Accordingly, the contribution margin per unit formula is calculated by deducting the per unit variable cost of your product from its per unit selling price.
