How long does it take to reach B1, B2 or C1? Hours per CEFR level, by language
Most learners want one number: how many hours until I can hold a real conversation, pass a B2 exam or work in the language? There is no single answer, but there are two well-sourced starting points: Cambridge English’s guided learning hours for each CEFR level, and the US Foreign Service Institute’s estimates of how much longer some languages take than others. Here is what both say, what they leave out, and how to combine them into a rough estimate for your own goal.
The quick answer: hours per CEFR level
Cambridge English, which runs the exams from A2 Key to C2 Proficiency, publishes guided learning hours for each level. They count lessons plus supervised study, cumulatively from zero, for people learning English:
| CEFR level | Guided learning hours, counted from zero |
|---|---|
| A1 | Not listed |
| A2 | About 180–200 |
| B1 | About 350–400 |
| B2 | About 500–600 |
| C1 | About 700–800 |
| C2 | About 1,000–1,200 |
Source: Cambridge English, “Guided learning hours”.
Read down the column and a pattern appears: each step up takes roughly another 200 hours, and the last one, from C1 to C2, takes more. Three caveats before you plan around these figures:
- They are guided hours. A guided hour is focused time with a teacher or a structured course, including the study that goes with it. An evening of podcasts in the background is not one.
- They are for English. How hard English is depends on where you start. The next section shows how much the target language changes the picture.
- The CEFR itself defines abilities, not hours. The framework describes what you can do at each level. The hours are an exam provider’s estimate from experience, not part of the standard.
Why the language you learn matters
The US Foreign Service Institute (FSI) trains American diplomats in foreign languages and groups those languages by how long its English-speaking students typically take to reach “professional working proficiency”. That target belongs to FSI’s own scale, not the CEFR, though it is often compared with roughly C1. The hours are class hours in full-time intensive courses. The table lists only the languages Viglot teaches:
| FSI category | Typical course | Class hours | Languages |
|---|---|---|---|
| Category I | 24–30 weeks | 600–750 | Danish, Dutch, French, Italian, Norwegian, Portuguese, Romanian, Spanish, Swedish |
| Category II | 36 weeks | 900 | German, Indonesian, Malay |
| Category III | 44 weeks | 1,100 | Albanian, Bulgarian, Croatian, Czech, Finnish, Greek, Hebrew, Hindi, Hungarian, Persian, Polish, Russian, Serbian, Slovak, Thai, Turkish, Ukrainian, Vietnamese |
| Category IV | 88 weeks | 2,200 | Arabic (including Egyptian and Levantine), Chinese (Mandarin, in Simplified or Traditional script, and Cantonese), Japanese, Korean |

The spread is the useful part. A Category IV language takes about three times as many class hours as a Category I language to reach the same target. The categories track distance from English. Shared vocabulary, a familiar alphabet and similar grammar make Spanish or Swedish quick for an English speaker, while Japanese, Korean, Arabic and Chinese combine a new writing system with grammar that works very differently and little vocabulary in common with English.
All of these estimates assume your native language is English. If you are learning English, use the Cambridge figures above. If your first language is something other than English, the next section matters more than the table.
How your native language changes the estimate
FSI’s categories measure distance from English. Start from another language and the distances shift, sometimes dramatically. There are no reliable hour figures for every pair of languages, but the pattern is easy to see:
- Spanish speakers learning Portuguese recognize a large share of the vocabulary and most of the grammar from day one. Their hard work is pronunciation and false friends.
- Russian speakers learning Ukrainian already know the Cyrillic alphabet, a very similar case system and much of the everyday vocabulary, so they move far faster than an English speaker in a Category III language.
- German speakers learning Dutch find familiar word order, related words and similar sounds. Reading comes almost at once; sounding natural still takes practice.
- Hindi speakers learning Persian meet a surprising amount of familiar vocabulary, because Hindi took many everyday words from Persian, even though the script is new to them.
The same logic works in every direction. A Japanese speaker learning Korean starts with familiar grammar, and a Mandarin speaker learning Japanese already knows what many of the characters mean, while either of them may find Spanish harder than an English speaker would. Two things shorten the road for anyone: a second foreign language usually goes faster than the first, because you already know how to learn one, and a language you hear every day, at work or at home, adds hours you never have to schedule.
Why B1 to B2 feels like the longest step
On paper, B1 to B2 is an ordinary step of roughly 150–200 guided hours. In practice it is where most self-taught learners stall, and the reason is the kind of hours, not their number.
Up to B1, recognition carries you a long way: you see a word, you know it, you pick the right answer. B2 asks for production. You have to retrieve words under time pressure, build sentences in real time, follow native-speed speech and repair a conversation when someone misunderstands you. Hours spent recognizing what you already know do little for those skills, so learners keep adding time and feel no progress. Our guide on how to get from B1 to B2 covers the tactics that work.
It also helps to be honest about what counts as an hour. On Cambridge’s scale, an hour is focused: a lesson, a session of exercises that make you produce language, a conversation with a goal and feedback. Half-listening to a podcast while you cook is useful exposure, but it is not the kind of hour the table counts. Counting only focused time makes your estimate more realistic, and it usually makes the time you do spend more effective.
A rough estimate for your own goal
To turn the two sources into a personal number, start with the Cambridge hours for your step, then scale them by how hard your target language is for you. Three worked examples:
- B1 to B2, in English or a language about as hard for you: B1 sits at about 350–400 hours and B2 at about 500–600, so the step takes roughly 150–200 guided hours. At half an hour a day, that is about a year.
- Zero to B2 in a year: an hour and a half a day for a year adds up to about 550 hours, which lands around B2 for a language of English-like difficulty.
- Zero to B2 in Japanese, Korean, Arabic or Chinese: FSI’s Category IV takes about three times the class hours of Category I, so for an English speaker the same goal can take well over a thousand hours of focused study.
Treat these as rough orders of magnitude, not promises. Your native language, the languages you already know, how much you hear outside study time and, above all, what you do with each hour can move the real figure a long way in either direction.
Try it with your own numbers
Formula: hours = (Cambridge hours for your target level − Cambridge hours for your current level) × difficulty factor. The factor is 1 for English and FSI Category I, and 1.33, 1.63 or 3.26 for Categories II, III and IV (FSI class hours ÷ 675). A rough estimate, not a promise.
How to make each hour count
You can’t shrink the number of hours a language needs, but you can make sure each one does its job. Three habits matter most:
- Spaced repetition for vocabulary. Reviewing a word just before you would forget it keeps it with far fewer reviews than cramming does. Reviews that make you produce the word, not just recognize it, count for more.
- Speaking with a goal. A conversation that has to achieve something, such as booking, complaining or persuading, and that tells you afterwards whether you managed it, trains the real-time production every level above B1 asks for.
- Production-first exercises. Filling a gap, rebuilding a sentence or rephrasing it in your own words takes more effort than picking from four options, and that effort is what makes the hour count.
Viglot is built around these three habits: scenarios on topics you choose, spaced repetition for every word, and speaking practice with feedback, in 40+ languages. The core exercises and spaced repetition are free. Pronunciation, voice tasks, Make Yourself Understood, What Would You Say?, In Your Own Words, listening comprehension, cultural nuance and grammar exercises are Premium, and you can try them all free during the trial, no credit card needed.
Frequently asked questions
How many hours does it take to get from B1 to B2?
On Cambridge English’s scale for English, roughly 150–200 guided learning hours: B1 sits at about 350–400 hours from zero and B2 at about 500–600. For a language that is harder for you, expect more. FSI’s estimates for Category IV languages such as Japanese or Arabic are about three times those for Category I languages such as Spanish or French.
Can I reach B2 in a year?
From zero, in a language about as hard for you as English is on Cambridge’s scale, it is possible with steady daily study: B2 takes about 500–600 guided hours, and an hour and a half a day for a year adds up to about 550. If you are already at B1, half an hour a day for a year covers roughly the 150–200 hours of the next step. In a Category IV language such as Japanese, the same goal from zero takes well over a thousand hours, which in a single year means studying almost full time.
How long does it take to get from B2 to C1?
About 200 guided hours on Cambridge English’s scale: B2 sits at about 500–600 hours from zero and C1 at about 700–800. It often feels longer, because progress at this stage is about precision, tone and implicit meaning, which are harder to notice than new words.
Are FSI hours realistic for self-learners?
Use them as a ratio, not a promise. FSI hours are class hours in full-time intensive courses, measured on FSI’s own proficiency scale, for native English speakers. What transfers well is the comparison between languages: a Category IV language takes about three times as long as a Category I language. An hour alone with an app or a book is rarely as intense as an hour in a small full-time class, so plan generously.
Does the CEFR say how many hours each level takes?
No. The CEFR describes what you can do at each level, not how long it takes to get there. Hour figures such as Cambridge English’s guided learning hours come from exam providers, and they vary with the language, the learner and the course.
