What is Profit Margin

Profit Margin is one of the ratios to measure business’s profitability. The basic idea behind this measurement is to see how efficient the business generates revenue based on cost accrued. If the business can generate more revenue based on less cost, it is more efficient, and hence has higher profit margin
=> Profit Margin = (Revenue – Cost)/Revenue
Because Revenue – Cost is simply Net Income
=>Profit Margin = Net Income / Revenue

Commentary

Profit Margin is used to measure business’s profitability. Higher profit margin generally indicates the company has higher profitability. However, from investors’ point of view, high profit margin doesn’t mean it will have high return on equity, which is the major ratio investors are looking for. It is possible that a company can have high profit margin yet its return on equity is low. Besides that, profit margin may vary among different industries. However, it is still a valuable indicator because investors can calculate the profit margin year by year based on the company’s historical financial statement for internal comparison
