ROIC- Explained in Simple terms

How Smart Companies Grow your Money

Understanding ROIC: A Powerful Ratio

When most people think about a company’s success, they often look at earnings growth, profit margins, or revenue. But there’s one powerful metric that quietly sits in the background—and savvy investors know it separates good companies from truly great ones.

It’s called Return on Invested Capital, or ROIC. And once you understand it, you’ll never look at a business the same way again. I use ROIC as one of the important metrics under Capital Allocation while analyzing a company.

In case you missed it, you can read my article “How to analyze a company,” where I describe a methodological approach on how I analyze a company.

A Simple Analogy to Understand ROIC

Imagine you want to grow your savings by $2,000 over the next year. You have $100,000 to work with. One bank offers a 2% return, while another offers 4%. To earn that $2,000:

• At 2%, you’d need to park all $100,000.

• At 4%, you’d only need $50,000—you could use the other half for something else.

Both get you the same result, but one does it with far less capital. It’s more efficient.

Now, imagine a company doing the same thing. The less capital a company needs to generate profits, the better. That’s what ROIC tells us.

What Is ROIC?

ROIC = NOPAT / Capital Invested

It measures how efficiently a company uses its capital, from shareholders and debt holders, to generate profits.

For example:

• A company making $0.40 for every $1 invested has a 40% ROIC

• Another, making $0.05 per dollar invested, has a 5% ROIC

Which would you rather own?

A higher ROIC, like 40 cents per dollar, is better than a lower one, like 5 cents, because it shows the company is really good at turning its resources into profits.

Why High ROIC Companies Are Special

• They can grow faster without raising money or taking on debt.

• They don’t rely on market optimism, they generate real returns.

• They usually have a competitive advantage, whether it’s brand power, network effects, or scale.

ROIC is like a truth detector for business quality. If a company consistently earns a high ROIC over time, it’s likely because of something very hard to replicate.

ROIC + Growth = Magic

High ROIC is great. But pair that with growth, and you unlock compounding.

Let’s meet two pretend companies to see ROIC at work: Dividend Inc. and Reinvest Inc. Both start with $100 million to spend, and both have an ROIC of 20%, meaning they make $20 million in profit each year. But they use their profits very differently.

• Dividend Inc. doesn’t see many chances to grow. So, it gives its $20 million profit back to shareholders every year as dividends. After 25 years, it’s still making $20 million a year, no more, no less. Your investment doesn’t grow much beyond those dividends.

• Reinvest Inc. is luckier; it’s in a growing market, like selling lemonade at a busy summer fair. Instead of paying dividends, it reinvests its $20 million profit into more lemonade stands. The next year, it has $120 million to work with (the original $100 million plus $20 million). With its 20% ROIC, it now makes $24 million in profit ($120 million × 20%). It reinvests that $24 million too, growing its base to $144 million, and the year after, it makes $29 million. If it keeps this up for 25 years, that snowball effect turns its profit into $1.9 billion! That’s the magic of compounding, when a company with a high ROIC can reinvest its profits and grow bigger every year.

This shows why ROIC plus growth is so powerful. A company that can keep a high ROIC and find ways to reinvest its profits can grow your money like a snowball rolling downhill, getting bigger and bigger over time.

Why Profit Margins Aren’t the Whole Story

Many investors focus only on profit margins. But margins tell you how much profit you make per dollar of sales, not per dollar of capital invested.

Some businesses, like Walmart or Costco, have low margins but very high ROIC. They turn over inventory so quickly that every dollar of capital works extra hard (Dupont Analysis - below).

That’s why ROIC is the true test of how productive a business really is.

DuPont Breakdown for ROIC

1. Operating Margin (NOPAT / Revenue)
   ➤ This shows how much profit the company earns per dollar of sales, after taxes but before financing costs.
   ➤ It reflects operating efficiency and pricing power.

2. Capital Turnover (Revenue / Invested Capital)
   ➤ This shows how efficiently the company uses its capital to generate revenue.
   ➤ Higher turnover means the company needs less capital to support its sales.

A company can achieve a high ROIC in two ways:

• By having high operating margins (making a lot of profit per sale),

• Or by being highly capital efficient (generating a lot of sales from a small base of capital).

Example:

Company A makes more per dollar of sales, but Company B uses its capital more efficiently—and ends up with a higher ROIC (Eg: Walmart).

ROE and ROA?

Return on equity (ROE) and return on assets (ROA) can be misleading:

• ROE can be inflated by debt or buybacks.

• ROA mismatches profits (for shareholders) with assets funded by both debt and equity.

That’s why I focus only on ROIC, it’s a cleaner, truer measure.

---

So, What’s a Good ROIC?

• 10% ROIC: Decent

• 15%+ ROIC: Excellent

• 20%+ ROIC: Rare and powerful

If a company consistently earns above its cost of capital (typically ~7–10%), it creates value. Below that, it destroys value, even if it’s growing. I always look for companies with ROIC >15%

---

Balance Between ROIC and Growth

Sometimes, a company should improve its ROIC rather than chase growth. Other times, if ROIC is already high, focusing on growth creates more shareholder value.

For example, to grow revenues by 5%:

• At 10% ROIC, a company must reinvest 50% of profits to grow 5% (5%/10% = 50%)

• At 20% ROIC, only 25% reinvestment is needed to grow 5%, more cash left for shareholders (5%/20% = 25%). The company can distribute 75% of the profit to its shareholders.

This relationship helps explain why high ROIC businesses often generate more free cash flow, which is fuel for buybacks, dividends, or further growth.

✅ Final Takeaways

• ROIC shows how efficiently a company turns capital into profit.

• High ROIC + reinvestment = compounding machine.

• Focus on ROIC over margins or ROE/ROA.

• Look for 15%+ ROIC sustained over time; that’s a true quality signal.

• Growth only creates value when ROIC is above the cost of capital.
