How Long Does It Take to Become Fluent in a New Language?
Put in your starting level, the level you are aiming for, the language and how much you study, and this estimator works out roughly how many hours, days and months it will take — in plain numbers, with the Duolingo lessons and XP behind them.
Where are you now?
Which language?
Harder languages take longer because their vocabulary, grammar and writing system are further from English.
How much do you study?
Three quick examples
Try these in the estimator above to see how the numbers move.
Example 1 — French from zero to A2
From zero to A2 in French, at 20 minutes a day, every day. That is about 180–200 hours and 540–600 practice days — roughly 77–86 weeks — or about 3,600–4,000 lessons and 36,000–40,000 XP.
Example 2 — Mandarin from A1 to B1
From A1 to B1 in Mandarin, at 60 minutes a day, every day. That is about 750–930 hours and 750–930 practice days — roughly 107–133 weeks — or about 15,000–18,600 lessons and 150,000–186,000 XP.
Example 3 — Russian from B1 to B2
From B1 to B2 in Russian, at 30 minutes a day, 4 days a week. That is about 160–400 hours and 320–800 practice days — roughly 80–200 weeks — or about 3,200–8,000 lessons and 32,000–80,000 XP.
How the maths works
- Guided hours per level. The commonly published guideline for reaching each CEFR level from beginner is about 90–100 hours for A1, 180–200 for A2, 350–400 for B1, 500–600 for B2, 700–800 for C1 and 1,000–1,200 for C2. These are ranges, not exact numbers, and they count taught or structured study.
- Hours between your levels. The estimator takes the gap between your current level and your target level from those ranges.
- Language difficulty. The guideline figures are for languages close to English. Harder languages scale the hours up: about 1.3× for German-like languages, 1.6× for Russian-like languages and 3× for Arabic, Mandarin, Japanese and Korean — ratios taken from the U.S. Foreign Service Institute’s training times for English speakers.
- Your pace. Hours become practice days from your minutes per day, then calendar time from the days per week you study.
- In Duolingo terms. A typical lesson takes about 3 minutes and gives about 10 XP, so the estimator turns hours into a rough lesson count and XP total. Duolingo on its own rarely covers everything a level needs — speaking and writing practice outside the app still matter.
Guided hours to reach each level
| Level | What it means | Hours from beginner |
|---|---|---|
| A1 | Basic phrases, introductions | 90–100 |
| A2 | Simple everyday conversations | 180–200 |
| B1 | Independent in familiar situations | 350–400 |
| B2 | Comfortable at work or university | 500–600 |
| C1 | Fluent, precise, flexible | 700–800 |
| C2 | Near-native command | 1,000–1,200 |
Hours are cumulative from a complete beginner and are a guideline only — your background, age, intensity and exposure outside lessons all change the real number.
How much harder is your language?
| Group | Languages | Time vs. easiest group |
|---|---|---|
| Easier | Spanish, French, Italian, Portuguese, Dutch, Swedish | 1× |
| Medium | German, Indonesian, Malay, Swahili | About 1.3× |
| Harder | Russian, Polish, Turkish, Hindi, Thai, Vietnamese | About 1.6× |
| Hardest | Arabic, Mandarin, Japanese, Korean | About 3× |
The ratios come from U.S. Foreign Service Institute training times for English speakers reaching professional working proficiency: roughly 600–750 classroom hours for the easiest group, 900 for German, 1,100 for the harder group and 2,200 for the hardest group.
Questions about learning time, answered
Can Duolingo alone make me fluent?
For most people, no — and Duolingo’s own courses stop around B2. The app is strong on vocabulary, reading and listening, but fluency also needs speaking and writing with real people. Use Duolingo as the daily habit, then add conversation practice, reading and listening outside the app as you climb past A2.
Why a range instead of one exact number?
Because nobody learns at exactly the guideline pace. The published hour figures are ranges, your starting point is rarely exactly on a level boundary, and motivation, age and exposure outside study all move the real number. A range is the honest answer — plan on the middle, hope for the low end.
What do you mean by fluent here?
Most people mean B2: you can hold a conversation, follow the news, and work or study in the language without constantly struggling. C1 and C2 go beyond that — precise, flexible, near-native use. The estimator lets you pick any target, so fluent means whatever you choose.
Is 34 hours of Duolingo really one university semester?
That figure comes from a 2012 study Duolingo itself commissioned, which suggested about 34 hours covered a first semester of Spanish — measured only on a reading and listening placement test. Independent researchers questioned the comparison, so treat it as a rough, optimistic guide rather than a promise.
How do I reach my target sooner?
Two things move the date most: more minutes per day, and more days per week — consistency beats occasional long sessions. The other lever is mixing in real use: speaking, reading and listening outside the app count toward the same hours and make the app time stick better.
I already speak a related language. Does that change anything?
Yes — you will probably beat the estimate. The figures assume English as your only language. If you already speak, say, French and are learning Spanish — or Hindi and are learning Urdu — the shared vocabulary and grammar can cut the hours a lot. The estimator cannot know that, so take the result as a cautious upper estimate.

DuolingoGuides is an independent guide and is not affiliated with Duolingo. Hour figures are estimates from the commonly published CEFR guideline and the U.S. Foreign Service Institute’s language difficulty data — they are planning ranges, not a promise. Your real time depends on your background, your consistency and how much you use the language outside the app.
