How long does it take to learn German?
The two institutions that measure it most carefully agree on the order of magnitude. The school that trains American diplomats puts German at about 36 weeks of full-time study (828 class hours) to reach professional working ability, and the Goethe-Institut estimates 60β150 hours of instruction for A1 and 600β750 hours by the end of C1. German takes longer than Spanish or French, and the extra time goes into the grammar, not into the words.
What the two official estimates say
The Foreign Service Institute (FSI), the US State Department's language school, times how long its students take to reach an integrated score of 3 (Speaking + Listening) on the ILR scale. German sits one category above the Romance languages, and it is the only European language in that category:
| Category | Weeks of full-time study | Class hours | Languages it names |
|---|---|---|---|
| I | 24β30 | 552β690 | Spanish, French, Italian, Portuguese, Romanian, Dutch, Danish, Norwegian, Swedish |
| II | about 36 | 828 | German, Haitian Creole, Indonesian, Malay, Swahili |
| III | about 44 | 1,012 | Russian, Polish, Greek, Czech and many more |
Its week is 23 hours in class and 17 of self-study, so German's 36 weeks are well over a thousand hours of work in all.
The Goethe-Institut, Germany's own cultural institute and the body behind the Goethe-Zertifikat exams, publishes its estimate per level of the Common European Framework, in hours and in 45-minute lessons (Unterrichtseinheiten):
| Level | Hours of instruction | 45-minute lessons |
|---|---|---|
| A1 | around 60β150 | 80β200 |
| A2 | around 150β260 | 200β350 |
| B1 | around 260β490 | 350β650 |
| B2 | around 450β600 | 600β800 |
| C1 | around 600β750 | 800β1,000 |
| C2 | around 750+ | 1,000+ |
The ranges join end to end β A1 stops at 150 hours and A2 starts there β so they read as running totals from zero rather than hours for each level on its own, and that is how they are read here. The Goethe-Institut is careful to say the spread is real: earlier languages, time put in and living in Germany all move a learner along the range.
The two sources measure different things. The FSI times one group of full-time students against a speaking-and-listening test; the Goethe-Institut gives a planning range for classroom courses. Neither is a promise for a self-taught adult, and neither says what one evening a week will get you. They agree on the shape, which is the useful part.
Where the extra weeks go
The FSI gives German 828 class hours where Spanish and French get 690. Vocabulary does not explain the difference. On film and television dialogue, the first 1,000 German word forms cover 77.6% of what is said, more than Spanish manages; the long tail of compounds comes later and matters less than its reputation, as how many words you need to speak German measures.
The difference is in the parts of a sentence that English lets you leave alone. One way to see it is to set the first hundred lessons of two courses side by side. Verbavia (our own course) hand-writes every language in the same format, one grammar point a lesson, so the order in which the German and Spanish courses have to teach things shows where the time goes:
| What is being taught | German course, lessons | Spanish course, lessons |
|---|---|---|
| Regular verbs in the present | 8β9 | 8β13 |
| Noun gender and the article | 11β15 | 14β17 |
| The verb in second place | 8, 10, 19β20 | β |
| The accusative case | 24β26 | β |
| Separable verbs | 33β35 | β |
| The dative case | 39β43 | β |
| Prepositions and the case each takes | 44β49 | β |
| The first past tense | 52 | 41 |
| The verb at the end of a subordinate clause | 61β63 | β |
| Adjective endings | 74β76 | β |
Spanish spends lessons 41 to 54 on its two past tenses. German spends most of that stretch on the dative and the prepositions, and does not reach its spoken past until lesson 52. The extra weeks are in the noun phrase and the word order, not in the verbs.
Four things take the time.
- Gender. Every noun comes with der, die or das, and for most of them nothing in the noun tells you which. German articles and gender tests the rules that do predict it and measures how many nouns they leave over.
- Case. The article changes with the noun's job. Der Mann is the subject; den Mann is the object; dem Mann is the person something is given to. That is why Den Mann sehe ich ("the man, I see") can put the object first and still be clear.
- Word order. The verb sits in second place in a main clause (Heute lerne ich Deutsch), and goes to the very end of a clause after weil, dass or wenn (weil ich keine Zeit habe). An English speaker has to wait for the verb and hold the sentence until it arrives.
- Separable verbs. Aufstehen is "to get up", but in a sentence the prefix goes to the end: Ich stehe um sieben auf, "I get up at seven". The verbs themselves are ranked in the most common German verbs.
None of these is hard alone. What costs time is that nearly every sentence uses three or four of them at once.
What the extra time means at each level
A1. This is where German is most different from the Romance languages. A Spanish beginner can say a great deal with a few verbs and no case; a German beginner cannot say I see the man or I give the man the book without choosing between der, den and dem. Expect the first months to feel slower than a friend's Spanish, and expect much of the extra work to be in the articles.
A2. The machinery is in place, and what comes next is built on it: the past that never happened (wenn ich Zeit gehabt hΓ€tte, with its verb at the end like any wenn-clause), the small words that carry tone β doch, mal, ja β and how a story starts, moves on and ends. In the course the level closes on everyday situations: arranging to meet, ordering, paying, saying where it hurts.
B1. Listening catches up with reading. The course opens the level with German as it is actually spoken β waiting for the verb, hearing nicht and kein, the filler words, Austria and Switzerland β and then sets the relative clause, the reflexive verb and reported speech against each case in turn. It ends with paragraphs written and then checked for their cases.
B2. The hardest part of B2 German is not new grammar but doing several pieces at once. A sentence like weil der Zug, den ich nehmen wollte, ausgefallen ist ("because the train I wanted to take was cancelled") puts a relative clause inside a verb-final clause, with a case in each. Lessons 405 to 418 of the same course pair the verb-final clause with one other structure at a time: the accusative, the dative, the two-way prepositions, separable verbs, adjective endings, nicht and kein.
C1. Register takes over: the official German of a delivery that never came or a refund from the railway, and Konjunktiv I, the form news reports use for what someone said (er sagte, er sei krank, "he said he was ill"). It is first met at the end of A1; at C1 it comes back in every combination. This is the level the Goethe-Institut puts at 600β750 hours.
How long it takes on a daily course
The other unit worth knowing is days, because that is how most people actually study. The German course is written by hand, lesson by lesson. The lessons are about 20β30 minutes at the fullest setting; a shorter setting spreads each lesson's grammar over two or three days, so the same course simply takes longer:
| Level | Lessons | One lesson a day (20β30 min) | Balanced (15β20 min) | Essentials (8β12 min) |
|---|---|---|---|---|
| A1 | 1β101 | 101 days | 202 days | 303 days |
| A2 | 102β191 | 90 days | 180 days | 270 days |
| B1 | 192β321 | 130 days | 260 days | 390 days |
| B2 | 322β491 | 170 days | 340 days | 510 days |
| C1 | 492β691 | 200 days | 400 days | 600 days |
| Total to the end of C1 | 691 | 691 days | 1,382 days | 2,073 days |
Those are days of study, not calendar days, and a missed day pushes the whole table back. The grammar in the table above is all inside A1: the course front-loads the four things that make German slow, so that from A2 onward the lessons are building on a complete system rather than meeting a new case every month.
So how long does German take?
- To a working A1 β ordering, introducing yourself, simple sentences with the articles mostly right: the Goethe-Institut says 60β150 hours of instruction, and on a daily course of hand-written lessons about three to ten months, depending on the lesson length.
- To B1, the level of an independent everyday user: up to 490 hours in the Goethe-Institut's range.
- To professional level: the FSI's 36 weeks full-time, or 600β750 hours of instruction by the Goethe-Institut's estimate for C1.
German is slower than Spanish at the start and not much slower afterwards. The two are compared directly in how long it takes to learn Spanish and, for French, in French or German. Why the grammar costs what it does is in is German hard to learn; the compounds that make German look harder than it is are in the longest German words.
To find out where you are already, the German vocabulary test takes about two minutes. The 1,000 most common German words are free in frequency order, in the order the course teaches them.
