The amount of each dollar of sales that the business keeps after covering all costs, including interest charges, taxes, paying personnel, and the cost of raw materials, is known as the net profit margin. The net profit margin can be defined as the total earnings expressed as a percentage of revenue.

What is Net Profit Margin?

The ratio of a company’s or business unit’s profit to its total revenue (net sales) is known as the net profit margin, also known as net income margin or net margin. A percentage is used to represent net profit margin. Net profit is what is left over after all costs, such as taxes, interest, and operational costs, have been taken into consideration. In a nutshell, net margin is the portion of sales that a business retains as profit.

Investors can assess the proportional amount of profit a business generates from its revenue by computing the net profit margin of that company. Net margin, a crucial sign of overall financial health, is a great metric to consider when contrasting one business with another.

How to Calculate Net Profit Margin?

It is quite simple to determine a company’s net profit margin for any particular reporting period. A company’s net profit margin is determined by dividing its revenue by its net income, which is either indicated as such in its financial statements or can be calculated as revenue minus cost of goods sold, operational and other expenses, interest, and taxes. The net margin ratio is then expressed as a percentage by multiplying the resulting number by 100.

Net Profit Margin Formula

Net Profit Margin = Revenue – COGS – O – I – T / Revenue * 100

         Or Net Income/Revenue * 100


          COGS= cost of goods  sold

          O = operating and other expenses

          I = Interest

         T = Taxes

    1. Subtract the cost of goods sold (COGS), operating expenses, other expenses, debt interest, and taxes payable from the income statement.
    2. Multiply the outcome by revenue.
    3. Multiply the number by 100 to change it from a number to a percentage.
    4. As an alternative, find net income on the income statement’s bottom line and divide it by revenue. Calculate the amount by multiplying it by 100 to get the percentage.

Net Profit Margin Example

Let say a company has earned 50 Million Dollars revenue in year 2022.


50 million $

Their Cost of Goods sold

30 million $

Operating and other expenses

5 million $


1 million $


5 million $

Net Profit Margin = Revenue – COGS – O – I – T / Revenue x 100    

        = 50 – 30 – 5 – 1 – 5/50 * 100

        = 9/50*100

        = 0.18*100

        = 18%

Why Net Profit Margin is Important for any Business?

The most significant indicator of a company’s total profitability is probably its net profit margin. It is the proportion of a company’s or business segment’s net profits to revenues. The net profit margin, expressed as a percentage, reveals how much profit is made for every $1 in sales after all costs associated with generating those revenues have been taken into consideration.

Greater profit margins imply that a larger portion of each dollar of sales is retained as profit.

What is Good Net Profit Margin?

You might be wondering, “what is a good profit margin?” In general, a 10% net profit margin is regarded as typical, a 20% margin as high (or “excellent”), and a 5% margin as low. However, a decent margin will differ significantly per industry. Once more, these rules differ greatly by industry and business size and can be influenced by a wide range of other variables.


A quick formula to determine a company’s net profit margin might offer you a more accurate view of how well a company is doing rather than getting carried away with high figures and gross profits. The least investors and business owners can do is to educate themselves on profitability.

However, Net profit margin/selling price calculator can be useful for your own business. There are many product pricing strategies which can help you to know about the key metrics to keep in mind how to set the price of the products effectively for maximum profit.
