Frequently asked
Is Duolingo (DUOL) a high-quality business?+
Duolingo scores 82 out of 100 on Intrinsiqq's quality score, a weighted blend of 8 metrics each scored 0 to 100, which rates it a high-quality business on these measures. Recent figures include a 14.2% operating margin and a 9.1% return on invested capital.

The metric-by-metric breakdown is on this scorecard.
What does Duolingo's quality score measure?+
Intrinsiqq's quality score weighs revenue and free-cash-flow growth, operating margins, return on invested capital, change in share count, and balance-sheet strength, each computed from DUOL's SEC filings rather than opinion or sentiment. A higher score means a more durable, capital-efficient business; it is not a buy or sell signal. Open each metric on this page to see exactly where Duolingo scores well and where it falls behind.
What is Duolingo's return on invested capital (ROIC)?+
Duolingo earns about 9.1% on its invested capital, which is modest. ROIC measures how much profit a company generates per dollar put to work; sustained ROIC above its cost of capital is one of the clearest signs of a real competitive moat. Compare it to DUOL's margins and growth on this scorecard to judge durability.
How profitable is Duolingo?+
Duolingo runs an operating margin of about 14.2% and a net margin of about 38.4%. Revenue has grown at roughly 45.0% a year recently. High, stable margins usually point to pricing power and operating discipline. Margins are most telling next to growth and returns on capital, all of which feed this quality score. This is analysis from SEC filings, not investment advice.
