RoR takes into account taxes, interest, taxes, depreciation and amortization.

RoR=(net income)/revenue;
net income - A company’s total earnings (or profit). Net income is calculated by taking revenues and adjusting for the cost of doing business, depreciation, interest, taxes and other expenses. This number is found on a company’s income statement and is an important measure of how profitable the company is over a period of time. The measure is also used to calculate earnings per share.
