How long it takes to learn German — NoaLingua

About 900 hours, and what that means with a job

The US Foreign Service Institute puts German at about 900 class hours to professional working proficiency — roughly 36 weeks full time. At an hour a day that is around two and a half years. Conversational comfort arrives far sooner, at a couple of hundred hours.

The figure, and where it comes from

The Foreign Service Institute has been teaching languages to American diplomats since 1947 and measuring how long each takes. German sits in Category II — on its own, between the Category I languages at 600 to 750 hours and Category III — at about 900 class hours, roughly 36 weeks of full-time study, to General Professional Proficiency.

That position is informative in both directions. German is meaningfully harder for an English speaker than Spanish or French, by something like a third. It is also dramatically easier than Japanese, Korean or Chinese at about 2,200 hours. If you are choosing between languages, that spread is worth more than any opinion about which is more beautiful or more useful.

The assumption inside it that nobody quotes

The 900 hours are classroom hours in an intensive programme — around 25 hours a week of instruction, with three to four hours of individual study a day on top. The real investment behind the published figure is therefore larger than the figure, and it happens under conditions almost nobody reading this has.

This cuts both ways, which is why it is worth stating rather than skipping. It means 900 evening hours will not reproduce the FSI result exactly. It also means that measuring yourself against "36 weeks" while studying part-time will make you feel like a failure when you are simply doing it at a different rate.

At three hours a day
Around ten months to the band, if the hours are real and the material is at the right level. This is roughly what an intensive learner achieves.
At one hour a day
About two and a half years. This is the honest shape of the thing for somebody with a job, and it is a perfectly good outcome.
At twenty minutes a day
Seven years or so on paper — and this is where the arithmetic stops meaning much, because forgetting between sessions eats a large share of each one.

The milestones that arrive much earlier

General Professional Proficiency means handling a meeting, an argument and a newspaper in German. Very few people reading this need it, and the things they actually want come far sooner.

Ordering, asking directions and holding a slow, patient conversation arrive somewhere around 100 to 200 hours. Following a German crime series with a translated line on screen comes soon after, helped enormously by the fact that the genre repeats its vocabulary every episode. Following it without the second line is the leap, and it typically lands somewhere past 400 hours — which is also where most people say the language starts feeling real rather than studied.

What the evidence says

Each of these has a source and a date. Where we could not find one, the claim is not here.

German is FSI Category II: about 900 class hours, around 36 weeks, to General Professional Proficiency.
Roughly a third more work than Spanish or French, and well under half the Category IV figure for Japanese, Korean and Chinese. US Foreign Service Institute language difficulty categories, checked 2026-08-26
The FSI figure is intensive classroom time — around 25 hours a week — plus three to four hours of daily individual study.
Quoting 900 hours without this caveat is the most common mistake made with the number. Compare total hours, never elapsed months. FSI programme structure, as described alongside the category tables, checked 2026-08-26
New material decays sharply within the first day unless it is retrieved again.
Why hour counts mislead. An hour with no retrieval afterwards is not a whole hour of progress, and at twenty minutes a day the losses can approach the gains. Ebbinghaus’s forgetting curve, summarised with sources on our blog

From people who have done it

  • Time to proficiency is driven far more by how different the language is from your own than by aptitude or method.

What six months actually looked like, for one person

One person’s experience, not evidence. It is here because it is honest about what it is, and because a method nobody has actually run is worth less than one somebody has.

I booked the Goethe B2 exam for six months out at a point where I could not introduce myself, which is not a method so much as a forcing function. What made the hours happen was that they were hours I was spending anyway — German channels about technology, science, space and chess, instead of the English ones I would otherwise have watched.

I passed, and was sorry I had not signed up for C1. That is one person and one language, so treat it as an account rather than as evidence — but the part I would repeat is the deadline, and the part I would repeat twice is not using learner material. The full version is here.

Common questions about NoaLingua

Can I learn German in three months?

You can reach a useful conversational level in three months at several hours a day. You will not reach professional proficiency, and anybody promising that in three months is contradicting the FSI’s own measurements.

Is German harder than Spanish?

Yes, by roughly a third on the FSI’s numbers — about 900 hours against 600 to 750. The gap is mostly grammar; the vocabulary is closer to English than Spanish vocabulary is.

Do the hours have to be classroom hours?

No, but they have to be hours where you are processing German rather than reading about German. Watching with two subtitle lines and looking words up counts; watching passively with English subtitles largely does not.

Does knowing English make German faster?

More than most people expect. The two are closely related, and a large amount of core German vocabulary is recognisable once you know what to look for. The grammar is where the extra 200 hours go.
