Net Profit Margin

When you calculate a firm's net profit margin, you may determine how much of an after-tax profit the company retains for each dollar of revenue or sales it generates. The percentage of profit a company generates as a proportion of its total revenue may be determined by computing the net profit margin.

Although profit margins may differ depending on the sector or business, the result is always the same. The greater a company's net profit margin is compared to its rivals, the better off the company will be overall.

There Are Some Exceptions to the Rule

The regulation regarding the net profit margin does include a few notable exceptions. To go further into the reasoning for this, it would be necessary to engage in a complicated examination of the DuPont Return on Equity calculation. The abbreviated and abridged version is presented here.

A company that makes its money from sales may increase its absolute net profit by decreasing its net profit margin and encouraging customers to spend more money in its shops. This will result in increased revenue. Dillard's, a well-known department store, used this strategy in the past. As of the 31st of January 2020, it only had a net profit margin of 1.77 percent. This was a smaller profit margin than that of other merchants, such as Walmart at the time, which had 2.84% as of the same date.

When it comes to working with high-end companies, this strategy carries with it an inherent risk. "Going downstream" refers to driving prices down to increase sales. The company's business may suffer when consumers no longer see a store as credible.

A Guide to Calculating the Net Profit Margin

For investors to calculate the net profit margin from a firm's income statement, the conventional wisdom is that they should divide the after-tax net profit by sales. Even while this is the norm and widely acknowledged, many still feel it is necessary to factor in the interests of the minority. This will provide you with an estimate of the amount of money produced by the firm before payments were given to minority shareholders.

Putting Numbers Together

Either approach to determining a company's net profit margin might be considered valid; nevertheless, it is important to use the same mathematical formulas when comparing companies. It is important to compare each company using the same criteria. The procedure for each computation would be as follows:

  • Option 1: The net profit margin may be calculated by dividing the after-tax net income by the total revenue.
  • Option 2: The net profit margin may be calculated as follows: net income plus minority interest plus tax-adjusted interest divided by revenue.

One more time, a pricing strategy might be synonymous with reduced net profit margins. They do not necessarily indicate that there was a failure on the side of management in every case. Some businesses, particularly those in the retail industry, budget hotel chains, and restaurant chains are well-known for their low-cost, high-volume business models.

In other circumstances, a low net profit margin may indicate a pricing war contributing to a decline in earnings. When the year 2000 rolled around, this was the situation with the computer industry. There was a rise in the number of individuals purchasing personal computers; however, not everyone was willing or able to pay the inflated rates. The sellers lowered the pricing to attract customers. Even in return for promotion, they were willing to give away their items for free.


In 2009, Donna Manufacturing sold one hundred thousand widgets for five dollars apiece, with a cost of goods sold price of two dollars for each unit. The company's operational expenditures were $150,000, and the company paid income taxes amounting to $52,500. What is the percentage of net profit that was made? To reach the answer, you need to begin by determining the revenue or total sales. If Donna's sold 100,000 widgets for $5 apiece, the business made a total income of $500,000. The cost of products sold by the firm was $2 per widget, and the sale of 100,000 widgets at $2 each resulted in total expenses of $200,000.

  • This results in a gross profit of $300,000 for the company.
  • After taking into account the operational expenses of $150,000 and the gross profit of $300,000, you are left with an income of $150,000 before taxes.
  • After deducting the tax liability of $52,500, the remaining amount, which is your net profit, is $97,500.

After entering these figures into the calculation for the net profit margin, you will get the following:

  • $97,500 net profit ÷ $500,000 revenue Equals 0.195 net profit margin, or 19.5%.
  • As a result, the correct response is 0.195. Simply moving the decimal point gives us a net profit margin of 19.5%.
