This post is a bit complex. But I know people coming to work in Munich are usually highly educated and will not have a big problem with the math presented here.

I will try to answer the question: is a **private course** more expensive of a group course in a **language school**?

A language school in Munich offers 1 intensive course of German lasting 1 month for 265€.

**WOW!** That’s a fantastic price, one might think. Especially compared with the cost of a private teacher of German, in my case I ask 35€ per 45 min. There is really no comparison, one might think.

One moment, let’s have a closer look. Let’s read better the *details* of the offer, here you go:

*there are 3 hours of lesson per day, makes 180 minutes.**a course has max 10 students.**the lessons are from Monday to Thursday, that makes 16 days per course.*

180 minutes per 10 students means you have **only 18 minutes available** for you.

What’s the cost per minute?

cost per minute = 265/(16*18) = 92 ct/min

My fees are:

35€ every 45 minutes or,

31.5€ per 45 minutes if you take a 20 hours course.

Per minutes makes:

35/45 = 77 ct/min

31.5/45 = 70 ct/min

Surprise surprise, a **course in a school costs 92 cents per minute** while a course with a **private teacher costs only 77 cents per minute**.

The cost per minute of a *“cheap”* school is higher than the cost per minute of an *“expensive”* private German teacher.

Of course, the calculation required some **simplifications**. For example, I assumed that of the daily 180 minutes you can talk only 18 minutes on average and this is the time you actively learn. But for the sake of comparison, I needed a **starting** point.

Finally, **I demonstrated** that the time with a private teacher is used much more efficiently, I quantified this efficiency and showed that the cost of a private course is for sure comparable, if not better, to the cost of a language school.
