Profit margin or net profit margin is a ratio that describes how much profit a company makes for every dollar of sales. A companyâs profit margin is calculated by dividing net income by revenues. Revenues are the total sales and net income is the total sales minus costs. The profit margin of a company is expressed as a percentage, so a 15% percent profit margin translates into a $0.15 profit for every dollar of sales. A companyâs profit margin fluctuates each quarter and has a direct effect on its stock price. A companyâs market share, on the other hand, reflects the amount of products the company sold compared to the total number sold by all companies in a given market or industry.
