How long does it take to reach B1 in a new language?

What B1 actually means

B1 is the first “independent” level of the Common European Framework of Reference (CEFR). In plain terms, a B1 speaker can:

• understand the main points of clear speech and texts about familiar topics — work, school, leisure;
• handle most situations that come up while travelling or living in the language;
• talk and write in simple, connected sentences about experiences, events, plans and opinions;
• briefly give reasons and explanations.

A B1 speaker still makes mistakes, searches for words and struggles with fast native conversation on unfamiliar topics. B1 is “I can manage on my own”, not “I sound native”.

The two best-known estimates

Cambridge English publishes approximate guided learning hours — hours with a teacher, not counting homework — for its English exams: about 350–400 hours to B1 and 500–600 hours to B2, counted from the beginning, with around 200 hours per level. Cambridge stresses that these are guidelines and that learners may need more or less.

The U.S. Foreign Service Institute (FSI) estimates how long its own students — native English speakers in full-time, intensive classes — need to reach professional working proficiency, which is well above B1:

Two lessons follow from the FSI figures. First, distance from languages you already know changes the number dramatically — Korean takes an English speaker roughly three times as long as Spanish. Second, these are full-time courses with homework on top, so “class hours” understate total effort.

Why your number will be different

• Your languages. A Dutch speaker learning German, or a Spanish speaker learning Italian, starts with thousands of familiar words. An Arabic speaker learning Korean starts with almost none.
• What an hour contains. An hour of active practice — speaking, recalling, writing — is worth more than an hour of passive reading of rules.
• Regularity. Seven hours spread over a week beat seven hours on a Sunday, because memory is built by spacing.
• Exposure outside study. Living in the language, listening daily or using it at work adds hundreds of hours that do not feel like study.
• Your goal. Passing a B1 exam, which tests specific tasks, can need less time than reaching a comfortable, everyday B1.

A rough planning table

Using 375 hours as a midpoint for a language close to yours:

For a language far from any you know, multiply by two to three. These figures are for planning; real progress is rarely a straight line, and the middle levels often feel slower than the beginning.

How to make each hour count

1. Mix skills every week: vocabulary, grammar, listening, reading, speaking and writing.
2. Prefer active work: recall and produce, do not only re-read.
3. Review on a schedule, so last month’s words are still there.
4. Listen a lot at an easy level: comprehension at speed comes from volume.
5. Speak from the start, even alone, so production does not lag years behind.
6. Check against real tasks: can you explain a problem, describe your week, follow a news item on a familiar topic?
