ROE vs ROIC
ROE measures profit against shareholders' equity alone, so leverage can lift it; ROIC measures after-tax operating profit against all capital, debt and equity together.
The difference
Both ratios ask how well a company turns capital into profit, but they count a different pool of capital, so they answer different questions. ROE divides net income by shareholders' equity, which shows how efficiently management turns shareholder capital — including retained earnings — into net income, and it links profitability, asset use, and leverage in one number. ROIC divides net operating profit after tax (NOPAT) by invested capital — broadly total debt plus equity, less excess cash — so it measures the after-tax operating return on all the capital in the business, regardless of how that capital was financed. That difference in denominator is the whole story: because ROE looks only at the equity slice, financing moves lift it even when operations are unchanged — buybacks shrink the equity denominator directly, while borrowing leaves equity broadly intact and instead raises the assets-to-equity multiplier, so the same operating profit sits on a thinner equity base. ROIC keeps the full capital base in view and gives a cleaner productivity signal. Neither is the "right" ratio — ROE tells you what the equity holder's capital earned, ROIC tells you what the business itself earned on everything it uses.
Side by side
| Aspect | Return on Equity | Return on Invested Capital |
|---|---|---|
| What it measures | Profit earned per dollar of shareholders' equity | After-tax operating profit per dollar of all capital invested |
| Formula | Net income ÷ shareholders' equity | NOPAT ÷ invested capital |
| Capital counted | Equity only — the shareholders' slice | Debt plus equity, less excess cash — the whole capital base |
| Effect of leverage | Borrowing more can lift ROE with no operating change | Debt already sits in the denominator, so it is not flattered |
| Effect of buybacks | Buybacks shrink equity, lifting ROE even if operations are flat | Less distorted, since the base is total capital, not equity |
| Usual reference point | Many investors view sustained ROE above roughly 15% as strong | Compared with WACC: above it creates value, below it destroys value |
Which one to use
Reach for Return on Equity when…
ROE is the better lens when the question is what the shareholders' own capital produced — it is the return on the equity slice specifically, and it folds profitability, asset use, and leverage into a single number. It is also useful precisely because it is leverage-sensitive: read next to ROA and ROIC, a gap between them tells you how much of the result borrowing is doing. For financials, where debt is part of the operating model rather than a financing choice layered on top, equity-based returns are the conventional starting point.
Reach for Return on Invested Capital when…
ROIC is the better lens when the question is how productive the business itself is, independent of financing choices. Because it uses after-tax operating profit over debt plus equity, it lets you compare two companies with very different capital structures on the same footing, and it is the ratio you set against the cost of capital — a business creates value only when ROIC exceeds the cost of the capital it uses, and destroys value when it does not. That comparison also explains why growth is not automatically good: when ROIC sits below WACC, growing the capital base makes the problem larger.
The concrete mistake is ranking companies by ROE and reading a high number as proof of operating quality. A company can boost ROE simply by borrowing more or buying back stock, with the underlying operations unchanged — though the two work differently. Buybacks shrink shareholders' equity, the denominator, directly. Borrowing leaves equity broadly intact and instead raises the assets-to-equity multiplier, so the same operating profit is measured against a thinner equity base. Either way the ratio climbs while the business has not improved at all. The tell is a high ROE next to a much lower ROIC: that gap says leverage is doing the work, not the business. The reverse confusion also happens — assuming ROIC and ROE should roughly agree, when a wide, persistent spread between them is usually just the capital structure showing up.
How Quintarthai uses them
Both ratios appear together in Quintarthai's company financial panels and in the screener's profitability filters, so you can see ROE and ROIC side by side rather than one in isolation — see /app/. They are shown for education and comparison only; the platform does not tell you which number matters for your situation, and neither ratio is a recommendation.
