Work out language proficiency level instantly with clear inputs, formula shown and shareable results.
CEFR levels correspond to broad bands of guided learning hours, but the hours required scale with how distant the target language is from your first. Self-study counts less per hour than guided instruction, while immersion is worth several times either.
Effective hours
Effective = Guided hours + Self-study x 0.6 + Immersion weeks x 25
Adjusted hours
Adjusted = Effective hours / Difficulty factor
Level bands
A2 from 150; B1 from 280; B2 from 450; C1 from 700; C2 from 1,000 adjusted hours
Only as a planning guide. Aptitude, prior language learning experience and study quality vary the requirement by a factor of two or more.
Because it forces production and listening under time pressure across many contexts, which classroom hours cannot replicate.
