Net profit (NP) ratio
Net profit ratio (NP ratio) is a popular profitability ratio that shows the relationship between net profit after tax and net sales revenue of a business entity. It shows the amount of profit earned by an entity for each dollar of sales and is computed by dividing the net profit after tax by the net sales for the period concerned. Both the numbers needed to calculate this ratio can be taken from entity’s income statement or profit and loss account. Net profit ratio is also frequently referred to as profit margin on sales.
For the purpose of this ratio, net profit is the net income or net profit of the entity as exhibited by its income statement or profit and loss account. Unlike operating profit ratio which considers only operating profit, the numerator in net profit ratio is the profit number arrived at by considering all operating as well as non-operating revenues and expenses. The denominator used is, however, the net sales which is typically the entity’s primary source of revenue.
The relationship between net profit and net sales may also be expressed in percentage form. When it is shown in percentage form, it is known as net profit margin. The formula of net profit margin can be written as follows:
Examples of net profit ratio
The following data has been extracted from income statement of Zain & Maria corporation.
- Gross sales: $210,000
- Returns inwards: $10,000
- Net profit before tax: $50,000
- Income tax: 10%
Required: Compute net profit ratio of Zain & Maria corporation using above information.
= ($45,000* / $200,000**)
*Net profit after tax:
= $50,000 – ($50,000 × 0.1)
=$50,000 – $5,000
** Net sales:
= $210,000 – $10,000

Significance and Interpretation
Net profit (NP) ratio can be a useful tool for measuring the overall profitability and operating performance of a commercial entity. A high ratio number indicates an efficient management of operational affairs of the entity and a low number might indicate otherwise.
There is no norm to interpret this ratio. To see whether a business is constantly improving its profitability or not, the analyst should compare the ratio with the previous years’ ratio, the industry’s average and the budgeted net profit ratio.
The use of net profit ratio in conjunction with assets turnover ratio helps in ascertaining how profitably the management has managed and used the entity’s assets during the period concerned.
Net profit ratio should be applied in your analysis with caution because a low ratio may not always be a sign of bad operational performance. Entities would normally exhibit a low NP ratio when they adopt an affordable or low-price strategy with the purpose to grasp a larger market share. Such entities can improve their NP ratio only by some possible reduction in costs, because raising the price of their products or services would result in lost market share.
Another problem with net profit ratio is that it is not a long-term measurement of profitability. It is mostly calculated by using the numbers from a short-period (typically one year or less) operating result of the entity and therefore does not indicate anything about it’s ability to maintain operational performance on continuous basis. Moreover, an entity can temporarily improve its net profit ratio by delaying such expenditures which don’t have a significant immediate impact on profitability. For example, the management can intentionally postpone a periodic maintenance or similar other discretionary expenses etc. to gain a higher profit number and make the ratio temporarily look better.
