Net Profit After Tax Margin

Learn about the Net Profit After Tax Margin: definition, calculation, interpretation, and significance in evaluating business profitability.

The Net Profit After Tax Margin (NPAT Margin) is a profitability ratio that measures a company's ability to generate profit after all expenses and taxes have been deducted. It represents the portion of a company's revenue that is left as profit after accounting for all costs and taxes.

The formula for the NPAT Margin is:

NPAT Margin = (Net Profit After Tax) / Revenue


Net Profit After Tax is calculated as Revenue minus Total Expenses and Taxes, where Revenue is the total amount of money a company earns from sales, and Total Expenses and Taxes are the costs associated with running the company's operations and taxes owed to the government.


A general rule of thumb for the NPAT Margin is to aim for a ratio of 5% or higher, although the ideal ratio varies depending on the industry and specific circumstances of the company. A higher NPAT Margin indicates that a company is generating more profit after accounting for all expenses and taxes, while a lower NPAT Margin may indicate that the company is struggling to generate profit or is facing high expenses and taxes.
