What is Margin?

Margin represents the difference between the revenue (or sale price) of an item and its cost, expressed as a percentage of the sales price. Essentially, it tells you the percentage of sales revenue that exceeds the cost of goods sold. It's a crucial metric for businesses because it indicates how much money the company retains for each dollar of sales, before considering other operating expenses.

How to Calculate Profit Margin 

Calculating your profit margin is simple! Here are step-by-step instructions with an example:

  1. Identify your sale price (or revenue) ($30)
  2. Identify your cost ($9)
  3. Calculate your net profit by subtracting cost from price ($30 - $9 = $21)
  4. Take your net profit and divide it by your price ($21 / $30 = .7)
  5. Multiply your net profit by 100 (.7 * 100 = 70%)
  6. Your profit margin is 70%

Profit Margin Formula

To calculate profit margin, you'll need two main figures: Gross Profit and Revenue (or Sale Price). 

The profit margin formula is:

Profit Margin = (Gross Profit / Revenue) × 100


Gross Profit = Revenue - Cost

Key Terms

  • Revenue - total sales or price of an item
  • Price - the price of a single item
  • Cost - what is costs you to product an item(s)
  • Cost of Goods Sold (COGS) - a more formal term for cost
  • Margin - ratio of profit to revenue
  • Gross Profit - profits before you subtract manufacturing or operating costs
  • Net Profit - profit after subtracting manufacturing or  operating costs
  • Markup - determines how much more than the cost you're charging for a product


What’s the difference between Margin and Markup?

Margin refers to the profit as a percentage of the sale price, while markup refers to the profit as a percentage of the cost. For example, if an item costs $80 and you sell it for $100, the markup is 25% (because the profit of $20 is 25% of the cost price) while the margin is 20% (because the profit of $20 is 20% of the sale price).

Margin tells you how profitable you are, while Markup tells you how much more your selling price is compared to cost.

What’s the difference between gross profit and net profit?

Gross profit is the profit a company makes after deducting the costs associated with making and selling its products, or the costs associated with providing its services. Net profit, on the other hand, deducts all expenses, not just direct costs, from sales. This includes operating expenses, interest, taxes, etc.

What is a good profit margin?

A "good" profit margin varies by industry and size of the business. Generally, a higher profit margin indicates a more profitable company that has better control over its costs. However, it's crucial to compare a company's profit margins to those of its competitors and the industry average. 

Margins above 10-20% are considered healthy.

How to calculate margin in Excel?

  2. Enter your cost of goods sold in cell B1.
  3. In cell C1, input the formula =(A1-B1)/A1 to calculate the margin as a ratio.
  4. To get it in percentage form, format cell C1 as a percentage.

How to calculate margin in Google Sheets?

The steps are similar to Excel:

  1. Enter your revenue in cell A1.
  2. Enter your cost of goods sold in cell B1.
  3. In cell C1, input the formula =(A1-B1)/A1.
  4. Format cell C1 as a percentage.

How do I calculate a 10% margin?

If you want a product to have a 10% profit margin, and you know the cost, the selling price would be calculated as:

Revenue = Cost / (1 - 0.10)

How do I calculate a 20% margin?

Revenue = Cost / (1 - 0.20)

How do I calculate a 30% margin?

Revenue = Cost / (1 - 0.30)

What is an 80% margin?

An 80% margin means that 80% of the selling price represents profit, while only 20% of the selling price covers the cost of the goods or services sold.
