📊 CEFR Proficiency Hours Estimator

Select a target CEFR proficiency level and your weekly study hours to see a rough estimate of total study time needed and projected timeline, based on commonly cited language-learning hour estimates.

Target CEFR Level

Weekly Study Hours

How the estimate is worked out

The tool holds one fixed hour figure per level and divides it by the hours you put in each week:

weeks  = ceil(total hours / weekly hours)
months = weeks / 4.345

A1 80    A2 200   B1 400
B2 600   C1 800   C2 1000   (cumulative hours from zero)

Choose B1 and enter 5 hours a week and you get 400 / 5 = 80 weeks, or 18.4 months. Weeks are rounded up, so 7 hours a week returns 58 rather than 57.1. The figures are cumulative totals, not the extra hours on top of the level below: B1 to B2 is the 200-hour gap between 400 and 600.

What the levels actually mean

A1, A2 – familiar everyday phrases (A1); sentences covering immediate needs such as shopping, family and local geography (A2).
B1, B2 – handling most situations that arise while travelling and writing simple connected text (B1); following complex text on concrete and abstract subjects and talking to native speakers without strain on either side (B2).
C1, C2 – fluent, spontaneous use for academic and professional purposes (C1); understanding virtually everything read or heard (C2).

Published hour figures – the Foreign Service Institute’s 600 to 750 class hours for Category I languages such as Spanish, against about 2,200 for Arabic, Chinese, Japanese and Korean – are institutional averages for full-time classroom study, not predictions for an individual. The single number used here ignores language difficulty altogether.

Frequently asked questions

How many hours does it take to reach B2 in a language?

This tool uses 600 cumulative hours, the range schools commonly quote for a language close to your own. For a distant one, FSI’s full-time programmes run several times that, and their numbers describe classroom cohorts rather than any single learner.

Does 10 hours a week get me to B1 within a year?

On these numbers, yes with room to spare: 400 / 10 = 40 weeks, about 9.2 months, which is under an hour a day.

Which CEFR level counts as fluent?

CEFR avoids the word. B2 is where you interact with native speakers with a degree of fluency and spontaneity, the level most universities and employers ask for; C1 and C2 describe flexible, near-effortless use rather than a different kind of fluency.
