How Long Does It Take to Learn a Language?

About This Calculator

This calculator is based on the U.S. Foreign Service Institute (FSI) language difficulty rankings, providing scientific estimates for how long it takes English speakers to learn various languages. We also include adjustments for non-English native speakers to provide more accurate estimates.

FSI Language Categories

FSI classifies languages into five difficulty categories: Category I (Easy, 575-600 hours) includes Spanish, French, and other languages similar to English; Category II (Medium, 750 hours) is German; Category III (Medium-Hard, 900 hours) includes Indonesian and Swahili; Category IV (Hard, 1,100 hours) includes Russian, Thai, and more; Category V (Super Hard, 2,200 hours) includes Chinese, Japanese, Korean, and Arabic.

CEFR Proficiency Levels

CEFR (Common European Framework of Reference for Languages) defines six proficiency levels: A1/A2 (Basic) for simple communication, B1/B2 (Independent) for work and academic exchange, C1/C2 (Proficient) for near-native fluency. This calculator defaults to B2 (professional working proficiency), which corresponds to FSI standard hours.
