FSI Language Difficulty — How It Affects Your Total Budget
The Foreign Service Institute (FSI) classifies languages by difficulty for English speakers:
These are maximums — most learners blend methods. A realistic blended approach (apps + 2 tutor sessions/week) costs $100–$175/month.

Common Mistakes
1. Counting app time as equal to tutoring time. 1 hour on Duolingo is NOT 1 hour with a tutor — interactive conversation accelerates speaking 3–5× faster.
2. Ignoring material costs. Textbooks ($20–$60), workbooks, and specialized software are often overlooked. Amortize one-time costs over the full duration.
3. Choosing cheapest without accounting for dropout risk. >70% of free-app-only learners quit within 1 month. A $120/month group class with accountability often saves money long-term.
4. Not adjusting for language difficulty. Spanish takes ~600 hrs vs. Japanese ~2,200 hrs. Same budget, very different timelines.
5. Overlooking free institutional resources. Many public libraries offer Mango Languages or Transparent Language free — worth $100–$200/year.
