Calculate margin percentage given any two values of cost, revenue, profit or markup. Enter two known values and the margin calculator finds the others showing you the solution step-by-step.

Margin Definition and Related Terms

• Margin or Profit Margin - the percentage of revenue that is kept as profit; margin equals profit divided by revenue, times 100
• Cost - the expense required to make a product or provide a service
• Revenue - the amount of income received from the sale of a product or service; the selling price
• Profit - the difference between the cost of making a product and the selling price or revenue; profit equals revenue minus cost
• Markup - the percentage added to an item's cost to arrive at a selling price; markup equals profit divided by cost, times 100

Understanding Gross Profit Margin

Gross profit margin is profit margin calculated before deducting the cost of goods sold or the expenses of running a business. This calculator finds gross profit margin unless you provide figures related to net sales and profit.

Profit margin is an important metric used to assess business profitability. It is a ratio that shows how much profit a company makes for every dollar of revenue received.

Having a solid grasp of the relationship between cost, revenue, profit, margin, and markup is essential for managing a business and creating effective pricing strategies.

Consider the case where the cost of producing products increases and gross revenue remains the same. The profit margin decreases in relation to revenue. This is because the company pays more in production costs while revenue remains the same.

You could consider increasing product markup appropriately to increase revenue and retain the desired profit margin. The risk is that existing customers will experience a pricing increase and may look for the product elsewhere.

Another strategy is to maintain current markups and to focus marketing efforts on building the customer base. The intent is to sell more products and therefore increase the profit margin despite increased production costs.

For net profit margin and related sales metrics see the Profit Margin Calculator.

Calculate Margin

Remember these definitions as you review profit margin calculations and examples below.

• Profit = Revenue − Cost
• Revenue = Cost + Profit
• Profit Margin (%) = (Profit ÷ Revenue) × 100
• Markup (%) = (Profit ÷ Cost) × 100
• Cost = Profit ÷ Markup

Calculate Margin Given Profit and Revenue

The Standard Margin Formula: Profit Margin (%) = (Profit ÷ Revenue) × 100

• Profit = $30
• Revenue = $150
• Margin % = (30 ÷ 150) × 100 = 20%

Calculate Margin Given Profit and Cost

Formula: Profit Margin (%) = (Profit ÷ (Profit + Cost)) × 100

• Profit = $25
• Cost = $100
• Revenue = Cost + Profit = 100 + 25 = $125
• Margin = (25 ÷ 125) × 100 = 20%

Calculate Margin Given Profit and Markup %

First, divide markup by 100 to get markup in decimal form: Markup ÷ 100 = markup
Formula: Profit Margin (%) = (markup ÷ (1 + markup)) × 100

• Profit = $125
• Markup = 43%
• markup = 43 ÷ 100 = 0.43
• Margin = (0.43 ÷ (1 + 0.43)) × 100
• Margin = (0.43 ÷ 1.43) × 100
• Margin = 0.3007 × 100 = 30.07%

You can see from the formula that profit does not affect the relationship between markup and margin.

Calculate Margin Given Cost and Revenue

Formula: Profit Margin (%) = ((Revenue − Cost) ÷ Revenue) × 100

• Cost = $80
• Revenue = $100
• Margin = ((100 − 80) ÷ 100) × 100
• Margin = (20 ÷ 100) × 100 = 20%

Calculate Margin Given Cost and Markup %

First, divide markup by 100 to get markup in decimal form: Markup ÷ 100 = markup
Formula: Profit Margin (%) = (markup ÷ (1 + markup)) × 100

• Cost = $80
• Markup = 50%
• markup = 50 ÷ 100 = 0.50
• Margin = (0.50 ÷ (1 + 0.50)) × 100
• Margin = (0.50 ÷ 1.50) × 100
• Margin = 0.3333 × 100 = 33.33%

You can see from the formula that cost does not affect the relationship between markup and margin.

Calculate Margin Given Revenue and Markup %

First, divide markup by 100 to get markup in decimal form: Markup ÷ 100 = markup
Formula: Profit Margin (%) = (markup ÷ (1 + markup)) × 100

• Revenue = $125
• Markup = 25%
• markup = 30 ÷ 100 = 0.30
• Margin = (0.25 ÷ (1 + 0.25)) × 100
• Margin = (0.25 ÷ 1.25) × 100
• Margin = 0.20 × 100 = 20%

You can see from the formula that revenue does not affect the relationship between markup and margin.
