# Calculating Net Profit Margin

Are you going to start a business? Do you already know how much money you want to earn? This is one of the first aspects that you have to consider. To do this, you must familiarize yourself with the net profit margin concept that possesses significant importance in bookkeeping.

## Net Profit Margin

The net profit margin of a product is the difference between the sale price to the final consumer (without value-added tax) and the costs of production or purchase of the said product. According to this, the formula to calculate the net profit margin is:

### Net profit margin = (Retail price without value-added tax) – (Production or purchase costs)

Furthermore, it is examined that the net profit margin is similar, but different from the “percentage of profit” term, by dividing the net profit of the sale into the cost of goods to help examine the sum of profit on the sale of the goods of a company, not the profit of the company. The individual figures of a company (such as income or expenses) can say a lot about its profitability. Looking at a company’s earnings often does not tell the full story. An increase in profit is a good indication, but it does not mean improving its overall profit margins. For example, let’s say that the revenue that Firm A provides in a year is \$2 million, with accumulated spending of \$ 650,000. This will provide a net profit margin of 67.5% (\$2M – \$0.65M / \$2M = 1.35M / \$2M = 0.675 = 67.5%). However, suppose that the revenue of the company increased next year to \$2.25 million, while spending increased to \$2.12 million, then the net profit margin would be 11.11% (2.25M – \$2M = 0.25M / \$2.25M = 0.11 = 11.11%). Despite the increase in revenue, Firm A’s net profit margin decreased as expenses increased more quickly than income.

Likewise, increasing or decreasing a company’s spending does not indicate that the company improves or worsens their net profit margin. Assume that Firm B has revenue and expense of \$2 million and \$1.5 million, respectively, in one year, which has a net profit margin of 25%. However, in the following year, the firm is restructuring by lowering its total revenue in lowering its expenditure by lifting a product line. If the second-year income and expenses of Firm B are \$1.5 million and \$1.2 million, the net profit margin is now 20%. Thus, Firm B has significantly lowered its costs, but the net profit margin has fallen because revenue falls faster than spending.

## Net Profit Margin Limitations

The net profit margin carries some concomitant limitations. However, it is a useful and popular rate. Like any financial indicator or rate, it is useful to assess the profitability of a company. However, the net profit margin can effectively compare a company’s performance within the same industry with similar business models. Several companies in the sector tend to have different business models and sources of income so that they can have very different net earnings. This can lead to comparisons, which generally do not make sense. For instance, a company that sells luxury products can have a high percentage of profits in its products and a low supply and a relatively low load while maintaining a high profit.

## Net Profit Margin Variations

There are several changes in the net profit margin that analysts and investors utilize to determine certain aspects of a firm’s profitability. Such a variation is the net profit margin acquired by dividing the net profit by the earned income. This change has some limitations, as management often has too much control over material costs. In such a scenario, the net profit margin is less effective in defining the overall management quality. Additionally, industries that do not have a manufacturing process have no or low sales costs. The net profit margin is effective when it comes to companies that are involved in producing certain goods. A specific variation of the net profit margin is the operating profit margin that divides the operating profit into income distributions. Traders and analysts can often use pre-tax profit margins by dividing their pre-tax earnings (revenue without deduction of tax costs) on a revenue basis.
