How Long Does It Take to Reach B1 or B2? A Realistic CEFR Timeline
An honest look at how long it takes to reach CEFR B1 and B2 with daily practice: what the levels mean, what published estimates say, what changes the timeline and how to plan your hours.

“How long until I’m B2?” is one of the most common questions in language learning, and one of the hardest to answer honestly. Anyone who gives you a precise number without asking about you is guessing. What we can do is explain what the levels mean, show what published estimates say, explain why individual timelines vary so much, and help you do your own rough maths.
What B1 and B2 actually mean
The Common European Framework of Reference for Languages (CEFR) describes six levels: A1 and A2 (basic user), B1 and B2 (independent user), C1 and C2 (proficient user). In everyday terms:
- B1 (threshold): You can handle most everyday situations while travelling, talk about familiar topics, describe experiences and plans, and understand the main points of clear speech on familiar subjects.
- B2 (vantage): You can interact with native speakers with a reasonable degree of fluency and spontaneity, understand the main ideas of fairly complex texts, and explain a viewpoint on a topical issue.
Two important notes. First, these are descriptions of what you can do, not word counts or grammar lists. Second, your skills will rarely be level: it’s common to read at B2 while speaking at B1, especially if most of your practice is reading.
What published estimates say
Two sources are often quoted. Both are useful, and both are easy to misread.
Guided learning hours (Cambridge English)
Cambridge English publishes approximate guided learning hours needed to reach each level when learning English. Its guidance is roughly:
| Level | Approximate cumulative guided learning hours |
|---|---|
| A2 | ~180–200 |
| B1 | ~350–400 |
| B2 | ~500–600 |
| C1 | ~700–800 |
Cambridge itself describes these as rough guidelines. “Guided learning hours” mean time with a teacher; they don’t include homework or self-study, and the real figure depends heavily on the learner. Treat the table as an order of magnitude, not a promise.
FSI language categories
The US Foreign Service Institute (FSI) groups languages by how long they typically take its English-speaking students to reach professional working proficiency. Vietnamese is in its “hard” category, alongside languages like Thai, Russian and Hindi, with an estimate of roughly 44 weeks (around 1,100 class hours) of intensive, full-time study.
That figure describes a demanding target, adult diplomats studying full-time in small classes with extra self-study, so it’s not a direct B1 or B2 estimate. What it does tell you is that, for English speakers, Vietnamese takes considerably longer than languages like Spanish or French, mainly because of unfamiliar vocabulary, tones and pronunciation. The same is true in reverse: English is a big jump for Vietnamese speakers too.
What changes your timeline
Two people who study the same number of hours can end up at very different levels. The biggest factors:
- Distance between languages. Shared vocabulary and similar grammar speed things up a lot. English and Vietnamese share very little core vocabulary and differ in sound systems, so expect a longer path either way.
- Previous language learning. If you’ve learned a second language before, you’ve already learned how to learn one.
- Quality of practice. Understandable input, active recall and speaking practice move you forward faster than passive exposure or rote lists.
- Consistency. Regular practice spreads learning over time, which supports long-term memory. See spaced repetition explained simply.
- Contact with the language. Living with it, working in it or having people to talk to adds hours you don’t have to schedule.
- Which skill you mean. Reading and listening usually progress faster than speaking and writing.
Doing the maths with daily practice
Let’s be honest about the numbers. Ten minutes a day is:
- about 70 minutes a week
- roughly 60 hours a year
If you compare that with the guided-hours table above, ten minutes a day on its own would take several years to reach B2. That’s not a reason to give up; it’s a reason to be clear about what a short daily habit is for.
Here’s a rough way to see how daily time adds up per year:
| Daily practice | Hours per year (approx.) |
|---|---|
| 10 minutes | ~60 |
| 20 minutes | ~120 |
| 30 minutes | ~180 |
| 60 minutes | ~365 |
These are just arithmetic, not predictions. Self-study hours aren’t directly comparable to guided classroom hours, and the quality of each hour matters a great deal.
So what is ten minutes a day good for?
A short daily session does three things very well:
- It keeps you in contact with the language every day, which matters for memory and for momentum.
- It steadily builds vocabulary and reading comprehension, which underpin every other skill.
- It makes the habit stick, so that when you have more time, you use it instead of starting over.
Most learners who reach B2 combine a daily core with something extra: classes, conversation practice, listening to podcasts or shows, or a stretch of more intensive study. The daily habit is the floor, not the ceiling. If you’re building that habit, start with how to learn a language in 10 minutes a day.
A realistic plan
Rather than chasing a date, plan by phases and check your progress against CEFR “can do” statements.
Phase 1: Foundations (A1–A2)
- Daily: short graded or bilingual readings, plus flashcard review.
- Weekly: listen to beginner audio, learn pronunciation basics (essential for Vietnamese tones and English vowel sounds).
Phase 2: Independence (toward B1)
- Daily: keep reading and reviewing; hide translations more often.
- Weekly: add some speaking, with a tutor, a language exchange partner or by reading aloud and recording yourself.
Phase 3: Fluency (toward B2)
- Daily: read longer texts and authentic material on topics you care about.
- Weekly: longer listening, regular conversation and some writing with feedback.
How to check your level
- Self-assessment: the official CEFR self-assessment grid lists what you should be able to do at each level. Be honest, skill by skill.
- Placement tests: many language schools offer free online tests; treat results as rough indications.
- Official exams: if you need a certificate, recognised exams for English (for example Cambridge English exams, IELTS or TOEFL) map their results to CEFR levels. Check which exams are recognised for your goal.
The honest answer
There’s no universal answer to “how long to B2”, and you should be wary of anyone promising one. Published guidance suggests it typically takes hundreds of hours, more for distant language pairs like English and Vietnamese, and more still when most of those hours are self-study. A short daily habit won’t get you there alone, but it’s the most reliable way to make sure the hours keep accumulating.
DailyFluent is designed to be that daily core: one short bilingual reading at your level, words you tap turned into spaced-repetition flashcards and a gentle streak. It’s launching soon for English and Vietnamese learners.
