What is 'AfterTax Profit Margin'
Aftertax profit margin is a financial performance ratio, calculated by dividing net income after taxes by net sales. A company's aftertax profit margin is important because it tells investors the percentage of money a company actually earns per dollar of sales. This ratio is interpreted in the same way as profit margin  the aftertax profit margin is simply more stringent because it takes taxes into account.
BREAKING DOWN 'AfterTax Profit Margin'
Often, a company's earnings don't tell the entire story. The amount of profit can increase, but that doesn't mean the company's profit margin is improving. For example, a company's sales could increase, but if costs also rise, that leads to a lower profit margin than what the company had when it had lower profits. This is an indication that the company needs to better control its costs.
