How to Calculate Net Profit Margin

Formula

Net Profit Margin = (Net Income / Revenue) x 100

Net profit margin is the ultimate bottom-line measure. It accounts for every cost the business incurs: cost of goods, operating expenses, interest, taxes, depreciation, and one-time charges. Tracking this metric over time reveals whether the company is converting an increasing share of revenue into profit.

计算示例

A company generated $1,000,000 in revenue and $120,000 in net income.

  1. Net Profit Margin = ($120,000 / $1,000,000) x 100 = 12%
  2. Total Expenses = $1,000,000 - $120,000 = $880,000
  3. Expense Ratio = $880,000 / $1,000,000 x 100 = 88%
