How long does a language actually take?
A free calculator built on current NFATC programme timelines — with Category I derived transparently from its weekly schedule, then adjusted for your target, languages and study method.
Difficulty is not a gradient
The current State Department training page publishes four categories, not a ranking. Category I contains two schedules; the other three are plateaus. Mandarin, Cantonese, Japanese, Korean and Arabic share one published figure, and the source does not separate them. The steps below are what that looks like.
Mandarin's 2,200-hour baseline is about 3.2× Spanish's derived 690-hour baseline under the same published programme and endpoint. It is a useful programme comparison, not a universal law about learners. The full table, or your own numbers.
Built to be argued with
Most answers to this question are a number with no working shown. Here is the working.
Current source-backed baselines
Spanish: 30 weeks, or 690 class hours using the page’s typical 23-hour class week. Mandarin: an explicit 2,200 — current State Department baselines for integrated ILR 3 in speaking and listening.
Your method, priced honestly
NFATC hours come from an intensive training schedule. An app is a different activity, and the gap widens the higher you aim. We model that difference instead of pretending it away.
It will tell you when to stop
Some plans cannot reach some levels at any hour count. In this planning model, app-only study is capped at B1. We say so rather than quoting a very large number that implies it is merely slow.
Credit for what you already speak
A Spanish speaker learning Portuguese is not starting where a monolingual English speaker starts. Every other calculator we found ignores this.
Every input labelled
One source-backed programme baseline, four judgement calls. Category I is transparently derived from the published weeks; every judgement is labelled with reasoning you can check.
Free options included
Our recommendations always include something that pays us nothing, because a shortlist that never does is an advert.
Start with a language
What the hours actually buy you, where learners stall, and how long it takes at the pace you can realistically keep.
How long does it take to learn Chinese (Mandarin)?
2200 NFATC class hours to integrated oral ILR 3
The current State Department training page puts Mandarin Chinese at 2,200 class hours to integrated ILR 3 in speaking and listening — the top category, alongside Arabic, Japanese and Korean. What that means at 30 minutes a day, and where learners actually stall.
ReadHow long does it take to learn Japanese?
2200 NFATC class hours to integrated oral ILR 3
The current NFATC page places Japanese in its 2,200-hour Category IV and gives no extra numerical penalty. What that benchmark means, and the three walls learners actually hit.
ReadHow long does it take to learn Korean?
2200 NFATC class hours to integrated oral ILR 3
The current State Department training page lists Korean at 2,200 class hours to integrated oral ILR 3. The alphabet takes an afternoon; almost everything after that is where the time goes.
ReadHow long does it take to learn Arabic?
2200 NFATC class hours to integrated oral ILR 3
The current State Department training page lists Arabic at 2,200 class hours to integrated oral ILR 3. But the figure leaves open a choice most guides never mention: which Arabic you are actually learning.
ReadHow long does it take to learn Russian?
1012 NFATC class hours to integrated oral ILR 3
The current NFATC page lists Russian at 1,012 class hours — about one and a half times Spanish and less than half of Mandarin. The alphabet takes a week; verbal aspect takes years.
ReadHow long does it take to learn Greek?
1012 NFATC class hours to integrated oral ILR 3
The current NFATC page lists Greek at 1,012 class hours — the same category as Russian, about one and a half times Spanish. You already know hundreds of Greek words; almost none of them are the ones you need.
ReadHow long does it take to learn German?
828 NFATC class hours to integrated oral ILR 3
The current NFATC page lists German at 828 class hours, between Spanish’s derived 690 and the 1,012-hour category. Why the words feel familiar and the sentences do not.
ReadHow long does it take to learn French?
690 class hours derived from the NFATC schedule to integrated oral ILR 3
The current NFATC page lists French at 30 weeks; using its typical 23 class hours per week, this site derives 690. Why the vocabulary is nearly free and the listening is not.
ReadHow long does it take to learn Spanish?
690 class hours derived from the NFATC schedule to integrated oral ILR 3
The current NFATC page lists Spanish at 30 weeks, transparently 690 class hours at its typical class schedule. What that benchmark means and where English speakers actually get stuck.
ReadHow long does it take to learn Italian?
552 class hours derived from the NFATC schedule to integrated oral ILR 3
The current NFATC page lists Italian at 24 weeks; using its typical 23 class hours per week, this site derives 552. Why the pronunciation is a gift and the input is the constraint.
ReadHow long does it take to learn Portuguese?
552 class hours derived from the NFATC schedule to integrated oral ILR 3
The current NFATC page lists Portuguese on its 24-week schedule, from which this site derives 552 class hours. But the choice between Brazilian and European Portuguese changes the difficulty more than any other decision on this site.
ReadHow long does it take to learn Dutch?
552 class hours derived from the NFATC schedule to integrated oral ILR 3
The current NFATC page lists Dutch at 24 weeks; using its typical 23 class hours per week, this site derives 552. The grammar is close to English; getting anyone to speak it back is the hard part.
ReadHow long does it take to learn sign language (ASL)?
The current NFATC page and cited ASL proficiency sources publish no comparable universal hour figure. A useful estimate must name its programme and endpoint.
ReadHow long does it take to learn Latin?
The current NFATC page and the cited Latin standards publish no comparable universal hour figure. The useful question is which reading endpoint you mean.
ReadHow long does it take to learn Polish?
1012 NFATC class hours to integrated oral ILR 3
The current NFATC page lists Polish at 1,012 class hours — the same category as Russian, but with a Latin alphabet you can read on day one and a sound system that takes far longer than the reading does.
ReadHow long does it take to learn Turkish?
1012 NFATC class hours to integrated oral ILR 3
The current NFATC page lists Turkish at 1,012 class hours. It is almost perfectly regular, has no grammatical gender and few irregular verbs — and it is still about one and a half times Spanish, because regularity is not the same as familiarity.
ReadHow long does it take to learn Hebrew?
1012 NFATC class hours to integrated oral ILR 3
The current NFATC page lists Hebrew at 1,012 class hours. The script runs right to left and mostly leaves the vowels out — but the harder cost is a vocabulary built from three-letter roots rather than from words you can look up as units.
ReadHow long does it take to learn Vietnamese?
1012 NFATC class hours to integrated oral ILR 3
Vietnamese uses the Latin alphabet and has no verb conjugation, cases or grammatical plural marking. NFATC lists 1,012 oral class hours but publishes no skill breakdown; this page examines the sound system without assigning it a share.
ReadHow long does it take to learn Swedish?
552 class hours derived from the NFATC schedule to integrated oral ILR 3
The current NFATC page lists Swedish at 24 weeks; using its typical 23 class hours per week, this site derives 552. Learning it also opens much written Norwegian and Danish.
ReadHow long does it take to learn Norwegian?
552 class hours derived from the NFATC schedule to integrated oral ILR 3
The current NFATC page lists Norwegian at 24 weeks; using its typical 23 class hours per week, this site derives 552. It is a practical route into Scandinavian with two written standards.
ReadHow long does it take to learn Danish?
552 class hours derived from the NFATC schedule to integrated oral ILR 3
The current NFATC page lists Danish at 24 weeks; using its typical 23 class hours per week, this site derives 552. Reading is friendly to Germanic-language speakers; listening is harder.
ReadHow long does it take to learn Thai?
1012 NFATC class hours to integrated oral ILR 3
Thai has no conjugation, no plurals, no cases and no gender. It also has five tones, its own alphabet and no spaces between words; the current NFATC page places it at 1,012 class hours.
ReadHow long does it take to learn Hindi?
1012 NFATC class hours to integrated oral ILR 3
The current NFATC page lists Hindi at 1,012 class hours. It is a distant relative of English, which shows up in the grammar and almost never in the vocabulary — and the language you learn is not quite the one people speak.
ReadHow long does it take to learn Finnish?
1012 NFATC class hours to integrated oral ILR 3
Fifteen cases, no gender, no articles, no future tense, and no relation to any language you are likely to know. The current NFATC page places Finnish at 1,012 class hours.
ReadHow long does it take to learn Hungarian?
1012 NFATC class hours to integrated oral ILR 3
Hungarian is surrounded by Indo-European languages and related to none of them. The current NFATC page places it at 1,012 class hours; the difficulty is almost entirely in how a sentence is built.
ReadHow long does it take to learn Czech?
1012 NFATC class hours to integrated oral ILR 3
The current NFATC page lists Czech at 1,012 class hours. Seven cases and a sound English has no name for are the famous obstacles — the underrated one is that the language everyone speaks is not the language textbooks teach.
ReadHow long does it take to learn Ukrainian?
1012 NFATC class hours to integrated oral ILR 3
The current NFATC page lists Ukrainian at 1,012 class hours, the same as Russian. It is a separate language with its own alphabet variant, seven cases, and a vocabulary that overlaps Russian in some registers and Polish in others.
ReadHow long does it take to learn Romanian?
552 class hours derived from the NFATC schedule to integrated oral ILR 3
The current NFATC page lists Romanian at 24 weeks; using its typical 23 class hours per week, this site derives 552. It is a Romance language with cases and suffixed articles.
ReadHow long does it take to learn Indonesian?
828 NFATC class hours to integrated oral ILR 3
No tones, no cases, no gender, no verb conjugation, no obligatory plural marking, and a Latin alphabet with regular spelling. The current NFATC page still lists Indonesian at 828 class hours — about 20% above Spanish's derived 690 — while the public timeline does not break down why.
ReadHow long does it take to learn Cantonese?
2200 NFATC class hours to integrated oral ILR 3
The current NFATC page lists Cantonese at 2,200 class hours — the same as Mandarin, listed separately. Six tones, no standard written form for the spoken language, and far fewer learning materials than its difficulty deserves.
ReadHow long does it take to learn Persian?
1012 NFATC class hours to integrated oral ILR 3
Persian is Indo-European, has no grammatical gender, no cases and largely regular verbs — and the current NFATC page still lists it at 1,012 hours. Its Arabic-derived script leaves out the short vowels, but the public timeline does not break down where those hours go.
ReadHow long does it take to learn Swahili?
828 NFATC class hours to integrated oral ILR 3
The current State Department training page lists Swahili at 828 class hours to integrated oral ILR 3. No tones, Latin alphabet, regular spelling, and a noun-class system that reaches into every word in the sentence.
ReadHow long does it take to learn Tagalog?
The current NFATC timeline does not list Tagalog, so there is no current official class-hour baseline to quote. Here is what makes the language fast at first and structurally difficult later.
