Enter the selling price per unit, variable cost per unit, and the total number of units sold into the contribution margin calculator. The calculator will display the contribution margin amount and ratio in percentage.

Contribution Margin Formula

The following formula is used to calculate the contribution margin.

CM = (SP * N) - (VC *N)
  • Where CM is the contribution margin
  • SP is the selling price per unit
  • N is the number of units sold
  • VC is the variable cost.

To calculate the contribution margin, subtract the product of the variable costs times the number of units sold from the product of the selling price times the number of units sold.

This yields the contribution margin amount. The contribution ratio can then be calculated by dividing the CM by the selling price per unit times the number of units sold.

Contribution Margin Definition

A contribution margin is defined as the difference between the revenue generated by an item and it’s associated variable costs.

How is contribution margin calculated?

Totaling up your cost of goods sold and your variable expenses (i.e., direct labor and overhead), you can calculate your contribution margin as follows:

Contribution Margin = Sales – Cost of Goods Sold – Variable Expenses

Contribution Margin = $10,000 – $7,000 – $3,000

Contribution Margin = $1,000*

What is contribution margin with example?

What is a contribution margin ratio?

Why is contribution margin ratio important?

Contributions margin ratio (also known as gross profit ratio) is one of the most important financial ratios. It measures how profitable a company is with each dollar of sales revenue.

How do you calculate contribution margin ratio?

1. Calculate the contribution margin for each product. To figure this out, divide the cost of goods sold for each product by its selling price. For example, if a product costs you $10 to make and you charge $12, your contribution margin is 25%.

2. Calculate the total contribution margin for each product line by adding up the individual contributions for all products in that line. In this example, there are two products in the line: Product X ($10 / $12) = 83% and Product Y ($15 / $18) = 79%. Total contribution margin = 82%.

3. Calculate the total contribution margin ratio by dividing the total of all contributions you calculated in Step 2 by the total sales revenue from Step 1 (you have to have both numbers to calculate this). Your CMR would be 82% ($2,400/$2,500) in this example.

What is the contribution ratio formula?

The formula for the contribution margin ratio is

Contribution Margin Ratio = Contribution Margin/Net Sales

Why is contribution margin important in healthcare?

This concept also offers a means for evaluating the effectiveness of marketing spending and pricing strategies in achieving profit objectives.

When a firm decides which products to offer or which markets to penetrate, it should examine each product’s contribution margins to determine if it will contribute enough profit to cover its fixed costs. If not, the firm cannot produce that product or not enter that market segment.

If a business has excess capacity and wants to generate more profits, it can increase prices or reduce variable costs per unit sold. Either action will have the effect of increasing the contribution margin for every unit produced and sold.

The contribution per sales ratio is a metric used by retail businesses to determine how much money they will make from each product that they sell. It is calculated as the profit made from a single sale. The formula for calculating this is:

Contribution/Sales = (Gross Profit/Sale) – Cost of Goods Sold


If you sell a product for $100, and it costs you $75 to make, your contribution per sales ratio would be: ( $25 / $100 ) – $75 = 25%

This means that if you sell 10 products, your total contribution would be $250. If your cost of goods sold was also $250, then you would achieve 100% contribution per sales ratio on that item.
