How to Use This Calculator
  1. Select your native language and target language to set the FSI difficulty category.
  2. Enter your daily study hours and study schedule (days per week).
  3. Input your target proficiency level (A1 through C2 on the CEFR scale).
  4. Review the estimated weeks and months to reach your target proficiency.
  5. Adjust daily hours to see how increasing study time shortens the timeline.

What each input means

Language Difficulty Category
1 = easy (Spanish, French), 2 = medium (German, Russian), 3 = hard (Hindi, Thai), 4 = super-hard (Mandarin, Arabic, Japanese).
Study Hours per Week
Average hours you plan to dedicate to study each week.
Prior Languages Known
Number of languages you already speak. Each reduces learning time by ~10% (max 30%).
Target Proficiency Level
1 = basic survival, 2 = conversational, 3 = professional working, 4 = near-native fluency.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Language Difficulty Category = 1, Study Hours per Week = 10, Prior Languages Known = 1, Target Proficiency Level = 3 = 4 input(s) provided
  2. Calculate Total Hours Needed
    Total Hours Needed
    540 = 540
  3. Calculate Weeks to Goal
    Weeks to Goal
    54 = 54
  4. Calculate Months to Goal
    Months to Goal
    12.5 = 12.5
