We'd all like to invest like the legendary Warren Buffett, turning thousands into millions or more. Buffett analyzes companies by calculating return on invested capital in order to help determine whether a company has an economic moat -- the ability to earn returns on its money above that money's cost.
ROIC is perhaps the most important metric in value investing. By determining a company's ROIC, you can see how well it's using the cash you entrust to it and whether it's actually creating value for you. Simply, it divides a company's operating profit by how much investment it took to get that profit. The formula is:
ROIC = Net operating profit after taxes / Invested capital
The nuances of the formula are explained in further detail here. This one-size-fits-all calculation cuts out many of the legal accounting tricks (such as excessive debt) that managers use to boost earnings numbers, and provides you with an apples-to-apples way to evaluate businesses, even across industries. The higher the ROIC, the more efficient the company uses capital.
Ultimately, we're looking for companies that can invest their money at rates that are higher than the cost of capital, which for most businesses is between 8% and 12%. Ideally, we want to see ROIC above 12%, at a minimum, and a history of increasing returns, or at least steady returns, which indicate some durability to the company's economic moat.
Let's take a look at Packaging Corp. of America (NYSE: PKG ) and three of its industry peers, to see how efficiently they use cash. Here are the ROIC figures for each company over a few periods.

*Because PKG did not report an effective tax rate, we used its 36% effective tax rate from three years ago.
**Because IP did not report an effective tax rate, we used its 26% tax rate from three years ago.
***Because UFS did not report an effective tax rate, we used its 39% tax rate from three years ago.
Packaging Corp. of America was showing steady increases in its returns on invested capital until it had a decline in its returns in the last four quarters. Two of the other listed companies followed a similar trend, while International Paper continued increasing its returns into this year.
Businesses with consistently high ROIC show that they're efficiently using capital. They also have the ability to treat shareholders well, because they can then use their extra cash to pay out dividends to us, buy back shares, or further invest in their franchise. And healthy and growing dividends are something that Warren Buffett has long loved.
