What is Contribution Margin Ratio?
The contribution margin ratio is a simple formula. It shows the percentage of sales that covers fixed costs. Fixed costs do not change with production. Examples include rent and salaries.
How to Calculate Contribution Margin Ratio
Step 1: Know Your Sales Revenue
First, you need to know your sales revenue. This is the total money from sales. For example, if you sell 100 toys for $10 each, your sales revenue is:
Sales Revenue = Price per Unit × Number of Units Sold
Sales Revenue = $10 × 100 = $1,000
Step 2: Know Your Variable Costs
Next, find out the variable costs. Variable costs can be materials, labor, and shipping. If the cost to make one toy is $6, then:
If you made 100 toys, the total variable costs are:
Total Variable Costs = Variable Cost per Unit × Number of Units Sold
Total Variable Costs = $6 × 100 = $600
Step 3: Calculate Contribution Margin
Now, we can calculate the contribution margin. This shows how much money is left after variable costs. The formula is:
Contribution Margin = Sales Revenue – Total Variable Costs
Contribution Margin = $1,000 – $600 = $400
Step 4: Calculate Contribution Margin Ratio
Finally, we find the contribution margin ratio. The formula is:
Contribution Margin Ratio = Contribution Margin ÷ Sales Revenue
Contribution Margin Ratio = $400 ÷ $1,000 = 0.4
To get a percentage, multiply by 100:
Contribution Margin Ratio = 0.4 × 100 = 40%
Example Calculation
Let’s do another example. Imagine you sell lemonade. You sell each cup for $2. You sell 200 cups. Your sales revenue is:
Sales Revenue = $2 × 200 = $400
Your variable costs are $1 per cup. So, total variable costs are:
Total Variable Costs = $1 × 200 = $200
Your contribution margin is:
Contribution Margin = $400 – $200 = $200
Now, calculate the contribution margin ratio:
Contribution Margin Ratio = $200 ÷ $400 = 0.5
Convert to a percentage:
Contribution Margin Ratio = 0.5 × 100 = 50%
Using Contribution Margin Ratio
Now that you know how to calculate the contribution margin ratio, how can you use it?
Here are some ways:
- Help set prices for products.
- Decide which products to sell more of.
- Determine how many products need to be sold to cover costs.
- Analyze changes in costs and sales.
