What is Gross Profit Mark Up?

Gross profit mark up, often simply called "mark up," is the percentage increase in the cost of a product or service to determine its selling price. It represents the percentage of cost that you add to make a profit.

How to Calculate Gross Profit Mark Up

The formula for calculating gross profit mark up is straightforward:

Mark Up = [(Selling Price - Cost of Goods Sold) / Cost of Goods Sold] * 100

Where:

  • Selling Price is the price you charge your customers.
  • Cost of Goods Sold (COGS) includes all direct costs associated with producing the goods or services, such as materials and labor.

Example: Let's say you buy a product for $50 and sell it for $75. Your mark up is [($75 - $50) / $50] * 100 = 50%. This means you're adding 50% to the cost to arrive at the selling price.

Gross Profit Mark Up vs. Gross Profit Margin

It's important to distinguish mark up from gross profit margin, which expresses profit as a percentage of revenue (selling price), not cost. The formula for gross profit margin is:

Gross Profit Margin = [(Selling Price - Cost of Goods Sold) / Selling Price] * 100

Using the same example, the gross profit margin is [($75 - $50) / $75] * 100 = 33.33%. Notice that the mark up (50%) is always higher than the margin (33.33%). This is because the denominator in the mark up calculation is always smaller (COGS) than the denominator in the margin calculation (Selling Price).

Why is Understanding Gross Profit Mark Up Important?

  • Pricing Strategy: Mark up helps you determine competitive and profitable selling prices.
  • Profitability Analysis: It indicates how much profit you're making on each product or service relative to its cost.
  • Financial Planning: Understanding mark up allows for better budgeting and forecasting, ensuring you cover costs and achieve desired profit levels.
