Return on invested capital (ROIC) is a financial ratio that measures the profitability and efficiency of a company’s capital investments by comparing net operating profit to the total amount of debt and equity used to fund operations.
Understanding return on invested capital
For Elephants looking to evaluate a business, ROIC provides a direct look at management performance. The calculation requires two main inputs: net operating profit after tax (NOPAT) and invested capital. NOPAT represents the cash earnings a company generates from its core operations after adjusting for taxes. Invested capital is the total amount of money raised by the company to operate. This figure typically includes both long-term debt and shareholder equity, minus any excess cash that is not needed for daily business activities.
By dividing NOPAT by invested capital, investors calculate a percentage that shows the cash return generated per unit of currency invested. A company with a 15 percent ROIC generates 0.15 in profit for every 1.00 of capital employed. This metric is useful for comparing companies within the same industry. Capital-intensive industries like manufacturing or telecommunications often have lower baseline ROIC figures than software or service companies, which require less physical infrastructure to operate.
To determine if a company is actually creating wealth, investors compare the ROIC to the weighted average cost of capital (WACC). WACC represents the average rate a company pays to finance its assets. If a company generates an ROIC higher than its WACC, it creates value for its investors. If the ROIC is lower than the cost of capital, the company destroys value, even if it reports a net profit on its income statement.
This metric applies universally to publicly traded and private companies across international markets. While the core formula remains the same globally, investors must account for differences in local corporate tax rates and accounting frameworks – such as the International Financial Reporting Standards (IFRS) or local accounting principles – when calculating the net operating profit after tax.
Example
Consider an agricultural business called Savannah Peanut Corporation, which is owned and operated by a herd of elephants. The elephants decide to expand their harvesting operations and need capital to purchase new automated tractors. They raise 500,000 in equity from the herd and secure a 500,000 loan from an international agricultural bank. This gives Savannah Peanut Corporation a total invested capital of 1,000,000.
At the end of the fiscal year, the elephants review their financial statements. The new tractors allowed them to harvest and sell a higher volume of peanuts, resulting in a net operating profit after tax of 120,000. To find their ROIC, the elephants divide the 120,000 NOPAT by the 1,000,000 of invested capital. The resulting ROIC is 12 percent. If the blended interest rate and equity cost for the business is 8 percent, the 12 percent return shows that the management team is effectively deploying capital to generate a surplus for the enterprise.
