Investopedia explains 'Profit Margin'
Looking at the earnings of a company often doesn't tell the entire story. Increased earnings are good, but an increase does not mean that the profit margin of a company is improving. For instance, if a company has costs that have increased at a greater rate than sales, it leads to a lower profit margin. This is an indication that costs need to be under better control.
Imagine a company has a net income of $10 million from sales of $100 million, giving it a profit margin of 10% ($10 million/$100 million). If in the next year net income rises to $15 million on sales of $200 million, the company's profit margin would fall to 7.5%. So while the company increased its net income, it has done so with diminishing profit margins.

- This ratio is not useful for companies losing money, since they have no profit.
- A low profit margin can indicate pricing strategy and/or the impact competition has on margins.
