What is the Contribution Margin?
The contribution margin is a measurement through which we understand how much a company’s net sales will contribute to the fixed expenses and the net profit after covering the variable expenses. So, while calculating the contribution, we deduct the total variable expenses from the net sales.
Contribution Margin Formula
To calculate this ratio, all we need to look at are the net sales and the total variable expenses. Here’s the formula –
Contribution Margin = Net Sales – Total Variable Expenses

It can be expressed in another way as well.
Contribution Margin = Fixed Expenses – Net Income
In situations, where there’s no way we can know the net sales, we can use the above formula to find out the contribution.
Example
Good Company has net sales of $300,000. It has sold 50,000 units of its products. The variable cost of each unit is $2 per unit. Find out the contribution, contribution margin per unit, and contribution ratio.
- The company has net sales of $300,000.
- The number of units sold was 50,000 units.
- Selling price per unit would be = ($300,000 / 50,000) = $6 per unit.
- The variable cost per unit is $2 per unit.
- Contribution margin per unit formula would be = (Selling price per unit – Variable cost per unit) = ($6 – $2) = $4 per unit.
- Contribution would be = ($4 * 50,000) = $200,000.
- Contribution ratio would be = Contribution / Sales = $200,000 / $300,000 = 2/3 = 66.67%.
In this example, if we would have been given the fixed expenses, we could also be able to find out the net profit of the firm.
Uses
You may ask why we need contribution. We need a contribution to find out the break-even point.
We will look at how contribution becomes useful in finding out the break-even point.
Let’s say that a firm’s fixed expenses are $100,000. The variable cost of the firm is $30,000. We need to find out the break-even point.
By using the concept of contribution, we will find out the break-even point.
Contribution Margin = Net Sales – Variable Cost = Fixed Cost + Net Profit
Here, we can write –
Net Sales – Variable Cost = Fixed Cost + Net Profit
At the break-even point, the key assumption is that there will be no profit or no loss.
Then,
- Net Sales – Variable Cost = Fixed Cost + 0
- Or. Net Sales – $30,000 = $100,000
- Or, Net Sales = $100,000 + $30,000 = $130,000.
That means $130,000 of net sales, the firm would be able to reach the break-even point.
