When it comes to evaluating companies, there are dozens of financial ratios investors throw around: ROE, ROA, ROIC, P/E, EV/EBITDA… the list goes on. But Warren Buffett, arguably the greatest value investor of all time, has always had a soft spot for a far less talked about measure — ROUNTA.
Never heard of it? You’re not alone. Most mainstream financial websites don’t even list it on their screeners. But for Buffett, it’s one of the best guides to understanding whether a company has real, lasting economics or just looks good on paper.
So what exactly is ROUNTA, and why does Buffett think it’s such a big deal? Let’s break it down in plain English.
What is ROUNTA?
ROUNTA stands for Return on Unleveraged Net Tangible Assets. Yes, it’s a mouthful. But the idea is simple:
It measures how efficiently a company generates profits compared to the tangible, unavoidable assets it actually needs to run its business.
Think about the basics: receivables, inventory, and fixed assets like factories or equipment. Every company needs at least some of these to operate. What ROUNTA asks is:
For every dollar tied up in those must-have tangible assets, how much profit does the business crank out?
That’s it.
Compare that to ROE (Return on Equity), which can be easily inflated by leverage, or ROA (Return on Assets), which lumps intangibles and goodwill into the mix. ROUNTA strips away the noise and zeroes in on the real nuts and bolts of the business.
Why Buffett Loves It
Buffett first brought up the idea in his 1983 shareholder letter, calling it “the best guide to the economic attractiveness of an operation.”
Why? Because it highlights the kind of businesses he actually wants to own:
- Companies that don’t need to plow tons of cash back into plants, equipment, or working capital just to stand still.
- Businesses with pricing power, strong brands, or unique advantages — what Buffett calls “economic goodwill.”
- Firms that can raise prices, grow profits, and expand without constantly begging shareholders for more capital.
In his own words, Buffett admitted he used to have it backwards. Early in his career, he favored companies with big tangible assets (factories, railroads, steel mills). Later, he realized the best investments were often the opposite — companies with minimal tangible assets but massive economic goodwill.
How to Calculate ROUNTA (Without Getting Lost in the Math)
Let’s break the formula down step by step, following Buffett’s 1983 definition.
1. Start with Pre-Tax Operating Earnings
Buffett uses pre-tax operating earnings as the numerator. Why pre-tax? Because we want to see the business’s earning power before the effects of financing decisions and tax strategies.
You should also add back goodwill amortization if it appears as an expense. Take See’s Candy, one of Buffett’s favorite case studies. Every year, the accountants reduced “goodwill” on the books, making profits look lower. But in reality, the value of the See’s brand — its economic goodwill — was growing, not shrinking.
So when calculating ROUNTA, add back goodwill amortization. Buffett often suggests about 80% of it isn’t a real economic cost.
2. Calculate Unleveraged Net Tangible Assets (UNTA)
This is the denominator. Here’s the key insight: we want to measure returns on the tangible capital the business uses, regardless of how it’s financed.
Start with tangible assets:
Tangible Assets = Total Assets – (Goodwill + Other Intangibles)
Now subtract only the non-interest-bearing liabilities (like accounts payable, accrued expenses, etc.). These are “free” financing that comes from suppliers and normal business operations.
UNTA = Tangible Assets – Non-Interest-Bearing Liabilities
Notice what we don’t subtract: interest-bearing debt. Why? Because debt represents capital that’s been invested in the business, just like equity. By keeping debt in the calculation, we’re measuring returns on all the tangible capital employed, not just the equity portion. That’s what makes it “unleveraged.”
Alternatively, you can think of it as:
UNTA = Equity + Interest-Bearing Debt – Intangibles
Both formulas give you the same result.
3. Put it all together
ROUNTA = Pre-Tax Operating Earnings ÷ Unleveraged Net Tangible Assets
Sounds technical, but in practice it boils down to: pre-tax profits divided by the hard tangible capital a company needs to operate, ignoring how that capital is financed.
This metric is calculated in our stock reports.
Why the “Unleveraged” Part Matters
The “unleveraged” aspect is crucial. It means we’re looking at the business’s operating performance independent of its capital structure.
Imagine two identical businesses, each earning $10M in pre-tax operating income:
- Company A: Financed with $100M equity, $0 debt
- Company B: Financed with $50M equity, $50M debt
Their ROE would be vastly different (10% vs 20%), but their ROUNTA would be identical because they’re the same business with the same tangible capital base. ROUNTA filters out the leverage illusion and shows true operational efficiency.
How ROUNTA Compares to Other Metrics
- ROE (Return on Equity): Inflated by debt and buybacks. ROUNTA avoids this.
- ROIC (Return on Invested Capital): Includes all capital, not just tangible assets. ROUNTA is more focused on the assets that matter most.
- ROA (Return on Assets): Weighs in intangibles and can be misleading. ROUNTA ignores those.
Buffett’s preference is clear: ROUNTA gets closer to the heart of what makes a company durably profitable.
Buffett’s Benchmarks for ROUNTA
In his 2010 letter, Buffett gave rough categories:
- Terrific businesses: 25%+
- Good businesses: 12–20%
- Poor businesses: Below 12%
Some Berkshire holdings, like See’s Candy, even post ROUNTA above 100%. That’s the magic of brand-driven, asset-light companies.
An Inflation Hedge
Here’s where it gets even more interesting.
In inflationary times, companies with high ROUNTA shine. Why? Because they don’t need as much extra capital to keep growing.
Imagine two businesses:
- Company A (High ROUNTA): earns $2M on $8M of tangible capital (25%)
- Company B (Low ROUNTA): earns $2M on $18M of tangible capital (11%)
If inflation doubles costs, both need to double their tangible capital base.
- A needs another $8M.
- B needs another $18M.
Company A invests less but earns far more. Over time, inflation punishes asset-heavy businesses while asset-light, high-ROUNTA businesses thrive.
See’s Candy: The Classic Case Study
Buffett bought See’s Candy in 1972 for $25M. At the time:
- Sales: $30M
- Pre-tax earnings: ~$5M
- Net tangible capital required: $8M
- ROUNTA: ~60% ($5M ÷ $8M)
By 2007:
- Sales: $383M
- Pre-tax profits: $82M
- Net tangible capital: $40M ($8M initial + $32M additional)
- ROUNTA: Over 200% ($82M ÷ $40M)
Cumulative pre-tax earnings over 35 years? $1.35 billion.
That’s the magic of high ROUNTA. Buffett only needed to invest $40M total in tangible capital, yet the business generated $1.35 billion in pre-tax earnings. The company kept compounding for decades without demanding significant new capital. This is what Buffett means when he talks about businesses with “economic goodwill” — the brand power and pricing power don’t show up on the balance sheet, but they generate extraordinary returns on the tangible capital employed.
What Drives High ROUNTA?
Usually, it’s intangible advantages that don’t show up on the balance sheet:
- Strong brands (Coca-Cola, See’s Candy)
- Network effects (Moody’s, Visa)
- Cost advantages (GEICO’s low-cost structure)
- Switching costs (Microsoft Office)
- Regulatory barriers (utilities, railroads)
Buffett calls this economic goodwill. High ROUNTA is just the financial expression of it.
How Investors Can Use ROUNTA
Okay, so how do you actually apply this?
1. Screen for quality.
Use our stock screener to find companies with ROUNTA >20% consistently over years. These are the businesses that tend to compound.
2. Watch the trend.
Is ROUNTA stable, rising, or falling? Improving efficiency often signals a competitive edge.
3. Compare within industries.
Some sectors (like railroads or utilities) will naturally have lower ROUNTA. Don’t expect See’s Candy levels there.
4. Don’t ignore valuation.
High ROUNTA businesses often deserve premium multiples. But don’t overpay. Even the best business can be a bad investment at the wrong price.
The Limitations
Like any metric, ROUNTA isn’t perfect. Here’s what to watch out for:
- Accounting quirks: goodwill adjustments require judgment.
- Industry differences: capital-heavy businesses will always look worse on this measure.
- Intangible-heavy firms: some tech companies technically have negative tangible assets, making ROUNTA calculations messy.
- Temporary boosts: asset sales or write-offs can distort results.
It’s a tool, not a crystal ball. Pair it with qualitative judgment.
ROUNTA in the Modern Market
Buffett’s wisdom still applies today, but some adaptation is needed.
- Tech companies: Many are asset-light, so ROUNTA can be sky-high. The challenge is making sure revenues are durable.
- Service companies: Again, very high ROUNTA possible. The key is whether their competitive moat is real.
- ESG concerns: A company can look efficient on paper but fail environmental or social standards. Long-term investors should weigh both.
Advanced Uses
For more serious analysis, you can:
- Track 5–10 year averages to smooth cycles.
- Break it down by segments in diversified firms.
- Compare against industry benchmarks.
- Adjust for extraordinary items.
In short, treat it as a living measure of economic reality, not just a static formula.
Why ROUNTA Matters for Everyday Investors
Here’s why I think ROUNTA deserves more attention in 2025:
- It cuts through accounting noise.
- It highlights companies with real pricing power.
- It signals inflation resilience.
- It matches Buffett’s own approach — proven over decades.
And perhaps most importantly: it reminds us that great businesses don’t constantly need more capital to grow. They just keep compounding.
Buffett summed it up perfectly: “The best kind of earnings are the ones that go up without more capital investment.”
That’s ROUNTA in a nutshell.
