How Do Gross Profit and Gross Margin Differ?

Gross profit and gross margin show the profitability of a company when comparing revenue to the costs involved in production. Both metrics are derived from a company's income statement and share similarities but show profitability in a different way.  

Gross Profit

Gross profit refers to the money a company earns after subtracting the costs associated with producing and selling its products. Gross profit is represented as a whole dollar amount, showing the revenue earned after subtracting the costs of production.

Gross profit is calculated by: 

$\begin{aligned}&\text{Gross profit}=\text{Net sales}-COGS\\&\textbf{where:}\\&\text{Net sales}=\text{Equivalent to revenue, or the total amount}\\&\quad\qquad\quad\text{\ \ \ \ \ of money generated from sales for the period.}\\&\qquad\qquad\text{\ \ \ \ \ It can also be called net sales because it can}\\&\qquad\qquad\text{\ \ \ \ \ include discounts and deductions from return-}\\&\qquad\qquad\text{\ \ \ \ \ ed merchandise. Revenue is typically called}\\&\qquad\qquad\text{\ \ \ \ \ the top line because it sits on top of the in-}\\&\qquad\qquad\text{\ \ \ \ \ come statement. Costs are subtracted from}\\&\qquad\qquad\text{\ \ \ \ \ revenue to calculate net income or the bottom}\\&\qquad\qquad\text{\ \ \ \ \ line.}\\&COGS=\text{Cost of goods sold. The direct costs associated}\\&\qquad\qquad\text{\ \ with producing goods. Includes both direct la-}\\&\qquad\qquad\text{\ \ bor costs, and any costs of materials used in pro-} \\&\qquad\qquad\text{\ \ ducing or manufacturing a company's products.}\end{aligned}$​Gross profit=Net sales−COGSwhere:Net sales=Equivalent to revenue, or the total amount     of money generated from sales for the period.     It can also be called net sales because it can     include discounts and deductions from return-     ed merchandise. Revenue is typically called     the top line because it sits on top of the in-     come statement. Costs are subtracted from     revenue to calculate net income or the bottom     line.COGS=Cost of goods sold. The direct costs associated  with producing goods. Includes both direct la-  bor costs, and any costs of materials used in pro-  ducing or manufacturing a company’s products.​

Gross profit measures how well a company generates profit from its labor and direct materials. Some of the costs include:

• Direct materials
• Direct labor
• Equipment costs involved in production
• Utilities for the production facility
• Shipping costs

Example of Gross Profit

As a historical example, let's consider Apple's September 30, 2017 gross profit reported from their consolidated 10-K statement the following:

• Net sales or (total sales or revenue) = $229 billion 
• Cost of goods sold (cost of sales) = $141 billion
• Gross profit = $88 billion (or $229B - $141B).

We can see that Apple recorded a total gross profit, after subtracting revenue from COGS of $88 billion for 2017 as listed on their income statement labeled as gross margin. Please note, the gross margin figure of $88 billion is an absolute dollar amount and should not be confused with gross profit margin, which is displayed as a percentage and which we'll address in the next section.  

Gross Profit Margin

Gross profit margin shows the percentage of revenue that exceeds a company's costs of goods sold. It illustrates how well a company is generating revenue from the costs involved in producing their products and services. The higher the margin, the more effective the company's management is in generating revenue for each dollar of cost. 

Gross profit margin is calculated by subtracting the cost of goods sold from total revenue for the period and dividing that number by revenue. 

 $\text{Gross Profit Margin}=\frac{\text{Revenue}-\text{Cost of Goods Sold}}{\text{Revenue}}$Gross Profit Margin=RevenueRevenue−Cost of Goods Sold​

Example of Gross Profit Margin

In the earlier example, Apple Inc. (AAPL), reported total sales or revenue of $229 billion and COGS of $141 billion as shown from their consolidated 10-K statement above. The gross margin dollar total was $88 billion. 

Gross profit margin for Apple in 2017:

 $\frac{\$229 \text{ (revenue)}-\$141 \text{ (COGS})}{\$229}=\textbf{38\%}$$229$229 (revenue)−$141 (COGS)​=38%

Apple earned 38 cents in gross profit when compared to their costs of goods sold. If a company's ratio is rising, it means the company is selling its inventory for a higher profit.

The Bottom Line

Gross profit and gross profit margin both provide good indications of a company's profitability based on their sales and costs of goods sold. However, the ratios are not a thorough measure of profitability since they don't include operating expenses, interest, and taxes.

Analysts and investors typically use multiple financial ratios to gauge how a company is performing. It's best to compare the ratios to companies within the same industry and over multiple periods to get a sense of any trends.
