Below 10% - weak
Capital isn't working hard. Common in capital-intensive or low-margin businesses; rarely a compounder.
A good return on equity is generally 15% or higher sustained over several years - but only after you check what drives it. ROE that comes from real operating quality is excellent; ROE manufactured with heavy debt is fragile. Use a DuPont breakdown to separate profit margin, asset turnover, and leverage. Roughly 15-20% from modest leverage is strong; below about 10% is weak.

15%+ is the rule of thumb, but always ask where the ROE comes from. A 25% ROE built on a mountain of debt is far weaker than an 18% ROE from fat margins and efficient assets. ROIC, which ignores leverage, is the honest cross-check.

Solid, provided leverage is moderate. A respectable but not exceptional use of shareholder capital.
The quality zone - as long as debt isn't doing the heavy lifting. Verify with a DuPont breakdown.
Elite if it's debt-light and durable; a warning if it's manufactured with leverage or buybacks.
Two companies both report 20 percent ROE. Company A: 10 percent net margin, decent asset turnover, almost no debt. Company B: thin margins, but it borrowed heavily so equity is tiny - leverage alone lifts the ratio to 20 percent.
DuPont analysis splits ROE into margin x turnover x leverage and exposes the difference instantly. Company A's return is durable; Company B's evaporates the moment earnings dip or rates rise. This is exactly why quality investors anchor on ROIC, which strips leverage out.
