How Long Does It Take to Learn English? Hours per CEFR Level

How Long Does It Take to Learn English?

Learning English to a confident independent level takes most learners hundreds of hours. Cambridge English estimates that a complete beginner needs about 500 to 600 guided learning hours to reach B2 on the CEFR scale and 1,000 to 1,200 hours to reach C2, the top level. How many months that takes depends on how many of those hours fit into each week.

"Learn English" has no finish line, so the useful question is how long it takes to reach a specific level. The CEFR (Common European Framework of Reference for Languages) gives six: A1 and A2 for basic users, B1 and B2 for independent users, and C1 and C2 for proficient users. Setting one of those six as the target turns a vague goal into a number of hours you can plan around.

Cambridge English, which writes exams at every CEFR level, publishes the hours estimate on its support site. The figures are cumulative, counted from zero rather than from the previous level, and Cambridge is careful to call them approximate.

If you do not know your current level, start with how to find your CEFR English level, which covers free placement tests and the self-assessment grid. The hours left to your target are the difference between where you are and where you want to be, not the full count from zero.

How Many Hours Does It Take to Reach Each CEFR Level?

Cambridge English's approximate guided learning hours, counted from complete beginner, are 90 to 100 hours for A1, 180 to 200 for A2, 350 to 400 for B1, 500 to 600 for B2, 700 to 800 for C1, and 1,000 to 1,200 for C2. Cambridge also gives a rule of thumb of roughly 200 hours to move up one level.

The subtraction shows two things the cumulative column hides. The first two levels are the cheapest, at under 100 hours each. The last step, from C1 to C2, costs more than any other, around 300 to 400 hours. Cambridge's example of the per-level rule is a learner with B2 First who needs approximately 200 hours of lessons and supervised study to prepare for C1 Advanced, which matches the table.

Vocabulary grows on a similar curve. Research estimates of how many words each CEFR level corresponds to are compared in how many English words you need to read and speak, and how to split study time between word lists and reading is weighed in whether to learn English words from lists or from context.

What Counts as a Guided Learning Hour?

A guided learning hour, in Cambridge English's usage, is an hour of lessons and supervised study, so the Cambridge estimates assume a teacher or a structured course. Cambridge does not publish a conversion for self-study time, app sessions, or hours of reading and listening on your own, which is why the table is a yardstick rather than a promise.

The definition matters because most adult learners do not sit in a classroom. Cambridge English's own list of factors that change the time needed includes "the amount of study/exposure outside of lesson times", which tells you two things. Practice outside lessons counts toward progress, and it sits on top of the guided hours rather than replacing them in Cambridge's model.

For a self-taught learner, the practical reading is this. An hour of focused work at the right level, such as a graded book read with full attention or an audiobook followed closely, is the nearest equivalent to a guided learning hour. An hour of English playing in the background while you do something else is not. Material that is too hard also weakens the hour, because comprehension collapses once too many words are unfamiliar, the effect described in comprehensible input and finding your right English reading level.

A structured self-study hour usually has three parts: input you mostly understand, a small number of new words or patterns to notice, and some way to review them later. Grammar reference such as the Dobi Apps English grammar guide and word lists in the English vocabulary guide can supply the second part. Reviewing new words on a spacing schedule, covered in how spaced repetition builds English vocabulary retention, supplies the third.

Does Your First Language Change How Long English Takes?

Yes. Your first language changes how long English takes, and the evidence comes from the reverse direction. The US Foreign Service Institute measured how well English-speaking Americans spoke other languages after the same training time, and languages closer to English scored higher. Researchers Barry Chiswick and Paul Miller turned those scores into a measure of linguistic distance from English.

Chiswick and Miller's paper uses scores from a 1993 Foreign Service Institute report by Lucinda Hart-Gonzalez and Stephanie Lindemann, which recorded the speaking proficiency of English-speaking Americans of average ability after 16 and 24 weeks of training in 43 languages. After 24 weeks, the scores ran from 1.00 for Japanese and Korean (hardest to learn) to 3.00 for Afrikaans, Norwegian, and Swedish (easiest).

Using these scores for learners going the other way, into English, rests on what Chiswick and Miller call "the assumption of linguistic symmetry": a language that is hard for English speakers to learn is assumed to make English hard for its speakers too. That is an assumption, not a measurement of English learners. It still gives a reasonable expectation. A Swedish or Dutch speaker will likely reach each CEFR level faster than the Cambridge midpoint, and a Japanese, Korean, Arabic, or Vietnamese speaker should plan for the upper end of each range or beyond.

What Else Changes How Long English Takes?

Cambridge English names four factors that change the time needed: your language learning background, the intensity of your study, your age, and how much study or exposure you get outside lessons. Of these, intensity has the clearest direct evidence. In a peer-reviewed 2007 study, adults who took 110 hours of English in five weeks outperformed those who spread 110 hours over seven months.

That study, by Raquel Serrano and Carme Muñoz in the journal System, compared three programs at one university in Spain, all delivering the same 110 hours of English. The extensive course ran four hours a week for seven months, the semi-intensive course eight to ten hours a week for three to four months, and the intensive summer course 25 hours a week for five weeks. The authors conclude that "concentrating the hours of English instruction in shorter periods of time is more beneficial for the students' learning than distributing them in many months."

Cambridge does not say whether younger or older learners are faster, and this post does not guess. Intensity has a limit for most adults too: 25 hours a week is a full-time course. The realistic lever for a working learner is adding regular practice outside lessons, which building a daily English learning habit covers step by step.

How Many Months Is That at 30 or 60 Minutes a Day?

At 30 minutes a day you study about 182 hours a year, and at 60 minutes a day about 365. Dividing Cambridge English's cumulative hours by those rates, a complete beginner studying one hour every day would reach B2 in roughly 16 to 20 months, and at 30 minutes a day in roughly 2.7 to 3.3 years.

The arithmetic is simple enough to check. Thirty minutes a day is 0.5 hours times 365 days, or 182.5 hours a year. For B2, 500 hours divided by 0.5 hours a day is 1,000 days, and 600 hours is 1,200 days. That is 2.7 to 3.3 years. At one hour a day the same B2 range is 500 to 600 days, about 16 to 20 months. Months below use 30.4 days per month.

These numbers assume every day counts and every hour is focused, so real calendars run longer. Missed days add up quickly at 30 minutes, which is one reason why English learners lose motivation and quit is worth reading before setting a deadline. If you already know your level, subtract its hours first. A B1 learner aiming for B2 needs about 150 to 200 more hours, roughly 5 to 7 months at an hour a day.

Why Does Progress Feel Slower at B1 and B2?

Progress in English often feels slower at B1 and B2, a stretch the applied linguist Jack C. Richards calls the intermediate plateau. In his booklet Moving Beyond the Plateau, Richards writes that learners moving from lower-intermediate to upper-intermediate levels often feel they have stopped improving despite steady effort.

Richards contrasts the plateau with the early stage, when basic learners "after their first 200 or so hours of instruction" begin to use English for real communication and progress feels obvious. At the intermediate stage he lists five common problems: a gap between what the learner understands and what they can say, fossilized errors that keep returning, fluency that grows at the expense of complexity, a limited vocabulary range, and speech that is correct but sounds too formal or bookish.

The Cambridge table explains part of the feeling. B1 to B2 takes about 150 to 200 guided learning hours, more than A1 to A2, so each visible step arrives later. Richards' remedies center on two ideas from second language research: noticing, where the learner pays conscious attention to features of the input, and pushed output, where speaking or writing tasks stretch the learner beyond the language they already use comfortably. Reading and listening to whole stories at your level gives plenty of input to notice, the approach in how to learn English effectively through stories.

How Can You Tell Whether Your Study Hours Are Working?

You can tell your English study hours are working by re-testing your CEFR level every few months and comparing the gain with the Cambridge English estimates. A learner logging an hour a day should cover roughly one level every 5 to 7 months in the B1 to C1 range. Much slower progress is a signal to change the material, not to add hours.

Keeping a simple log makes the check possible. Write down minutes studied each day and the type of practice, then total the hours when you re-test. If you have logged 200 hours since your last B1 result and a placement test still says B1, the Cambridge table suggests something other than time is holding you back. Common causes are material that is too easy or too hard, practice that is all input and no speaking, or new words that are met once and never reviewed.

The fix usually lies in the type of hour rather than the count. Level-matched reading and listening in Dobi Apps' Audiobook, where the library is sorted from A1 to C2, keeps input at the right difficulty. Speaking practice addresses the gap Richards describes between understanding and producing English. Spaced review keeps new words from fading between sessions.

Treat the Cambridge numbers as the baseline for that comparison. They describe hours of lessons and supervised study for an average learner, and Cambridge itself says the time needed varies "depending on your own needs". Your first language and weekly intensity will move your line above or below the baseline.
