ROIC — How Efficiently a Company Puts Its Capital to Work
Two companies each earned 10 billion KRW in net profit. A runs on 50 billion of equity; B runs on 20 billion of equity plus 30 billion of debt. On paper, ROE is A = 20% vs B = 50% — B looks far better. But B leans heavily on debt: one shock in a rising-rate environment and it crumbles. ROIC (return on invested capital) sidesteps this debt trap and measures the company's true capital efficiency.
1. Definition — after-tax operating profit over all invested capital
The components:
- NOPAT = Net Operating Profit After Tax = operating profit × (1 − tax rate). Before deducting interest expense — the after-tax profit generated by operations themselves.
- Invested Capital = equity + interest-bearing debt (net of cash and equivalents). All the money the company puts into the business.
The key: the numerator is the pure operating result before interest, and the denominator is total invested capital including debt. So whether a company uses a lot of debt or none, ROIC measures the business's true efficiency.
2. ROIC vs ROE — the debt-trap difference
The two companies above (both with NOPAT of 10 billion KRW, 25% tax rate assumed):
| Item | Company A | Company B |
|---|---|---|
| Equity | 50bn | 20bn |
| Interest-bearing debt | 0 | 30bn |
| NOPAT | 10bn | 10bn |
| ROE | 15% | 37.5% |
| ROIC | 20% | 20% |
ROIC rates the two companies as equals (their business efficiency is the same). ROE makes B look more than twice as good, but that gap is purely the product of debt leverage — when rates rise or revenue falls, B is far riskier.
Warren Buffett has said he doesn't trust ROE on its own. "ROE juiced by debt is froth" — he looks at ROIC together with the debt ratio instead.
3. ROIC vs WACC — the real signal of value creation
ROIC alone isn't enough. It only becomes meaningful when compared against the cost of capital (WACC, Weighted Average Cost of Capital).
ROIC < WACC → value destruction (shareholder wealth shrinks)
WACC is the company's average cost of raising capital (equity + debt + tax effects). US listed companies average around 7–10%; Korean listed companies around 6–8%. Only when ROIC exceeds WACC is the company genuinely creating value.
- ROIC 20%, WACC 8% — 12pp of value created every year. An excellent business.
- ROIC 9%, WACC 8% — barely breaking even. Sensitive to the cycle.
- ROIC 5%, WACC 8% — destroying value. The business model needs a rethink.
4. ROIC varies by industry
The same ROIC means different things in different industries. Capital-intensive businesses (steel, chemicals) are inherently low-ROIC; capital-light ones (software, consulting) are inherently high.
| Industry | Median ROIC (approx.) |
|---|---|
| Software / SaaS | 20–40%+ |
| Consulting / advertising | 15–30% |
| Manufacturing / consumer goods | 10–20% |
| Utilities / telecom | 5–10% |
| Steel / chemicals / shipbuilding | 3–8% |
These are rough ranges commonly cited in the industry, not an aggregation from any particular study or period. This article does not record which index, period or sample they came from (source verification needed). Read them only as a sense of how capital intensity differs across industries.
Compare within the industry. An 8% ROIC is excellent for a steelmaker and below average for a SaaS company.
5. Where Multifolios fits
Multifolios does not currently provide fundamental metrics (ROIC / ROE / WACC) — it focuses on tracking prices, allocations, and returns. For fundamental analysis, we recommend a workflow of using external tools (e.g. Stockanalysis.com, Macrotrends, FRED) and feeding the conclusions into your own decisions.
What Multifolios does help with: post-purchase allocation monitoring (target vs current), returns over time, and daily changes on the calendar — fundamental analysis → buy decision → monitor in Multifolios → rebalancing alerts.
6. One-line summary
ROIC = NOPAT / Invested Capital. Where ROE can be inflated by debt, ROIC shows the business's true capital efficiency. Is it above WACC, and how does it rank within its industry — those two questions are the heart of using ROIC.
