How Long Does It Take to Learn French?

The one published figure, and exactly what it counts

There is precisely one attributable, published number for how long French takes, and it does not describe you. The US Foreign Service Institute places French in Category I — its easiest band, "languages close to English" — and lists French at 30 weeks, inside a band the same page gives as 24 to 30 weeks, or 552 to 690 class hours. That was read from the State Department's own page on 24 September 2026.

Read the surrounding sentences, because they carry all the meaning. The FSI says these timelines "indicate the time usually expected for a student to reach an integrated score of 3 (Speaking + Listening) on the Interagency Language Roundtable scale" — a professional working standard, not a holiday standard — and that "a typical week is 23 hours per week in class and 17 hours of self-study". It adds that actual time varies with the learner's natural ability, prior language-learning experience and time spent in the classroom.

So the honest full sentence is: American government employees, selected and paid to do nothing else, studying about forty hours a week with professional instructors, typically take about thirty weeks to reach a professional working level in French. Nearly every version of this figure you have seen online has dropped most of those qualifiers.

Why French is 30 weeks when Dutch is 24

The most useful thing in the FSI's table is not the band but the spread inside it, which almost nobody quotes. Category I is not one number: Danish, Dutch, Italian, Norwegian, Portuguese, Romanian and Swedish are all listed at 24 weeks, while French and Spanish alone are listed at 30.

That is a quarter more classroom time than Dutch, for a language that on paper is no more distant from English. The FSI does not explain the gap on that page, so nothing here will claim to know the reason. But it lines up exactly with what French learners report: that the written language is manageable and the spoken one is not, because French runs its words together and moves the boundaries between them. Whatever the FSI's reason, the six extra weeks are a published fact and they are a useful corrective to "French is easy".

It is also worth noticing what the numbers are made of. Categories I, II and III are internally consistent at 23 hours a week — 24 weeks gives 552 hours, 30 weeks gives 690, 36 weeks gives 828, 44 weeks gives 1,012, all exactly. Category IV does not follow that rule: 88 weeks at 2,200 hours works out at 25 hours a week. That is a small thing, but it tells you these are planning figures maintained by hand rather than a formula, which is one more reason to treat them as a ranking rather than a stopwatch.

What the number cannot be used for

The figure is a ratio, not a timetable, and converting it into evening study is where every online guide goes wrong. You will see 690 hours divided by an hour a day and presented as "under two years to fluency". That arithmetic is invalid, and it is invalid in both directions.

It undercounts, because the FSI's hours are class hours only — the same page adds 17 hours of self-study a week on top, so a 30-week French course involves roughly 690 classroom hours plus around 510 hours of homework. And it overcounts the transferability, because intensive study is more efficient per hour than scattered study: a learner doing forty hours a week retains material differently from one doing five, and no published source converts between them.

It also measures a finish line most people are not aiming at. An ILR score of 3 in speaking and listening is the level at which you can work professionally in the language. If what you want is to hold a conversation on holiday, you are being quoted a figure for something four or five times harder.

This site will not publish a corrected number in its place, because there is not one. No certifying body, no government and no school publishes an hours-to-conversational figure for self-taught adults, and every table you have seen that does is either a vendor's marketing or a survey of learners passed between blogs until it acquired the look of a source.

"Learn French" is four different finish lines

Most of the disagreement about timing is really disagreement about the word "learn", and separating the finish lines removes most of the confusion.

Reading French well enough to get through an article in your own field is the fastest and the most underrated, because it draws on the enormous French-derived layer in English's formal vocabulary — some people reach it within months. Holding a slow, simple conversation about familiar things is a matter of months rather than years, but only if you start speaking early; for a learner who waits until they feel ready, it is a matter of never. Following unscripted French between native speakers at normal speed is the long one for this language specifically, for the segmentation reasons above. And working professionally in French is the FSI's target, and the only one its number actually describes.

Decide which of those you want before you ask anyone how long it takes. Most people asking mean the second and are quoted figures for the fourth.

What a seller's own pace claim is worth

Vendors do publish timelines, and they are worth reading as claims rather than facts. On its own site on 24 September 2026, Pimsleur's page carries the line "Speak at an Intermediate Level in 30 Days". That is the seller's unaudited claim about its own course, and it sits interestingly next to the FSI's 30 weeks of classroom time for a professional standard — the two are not in contradiction only because "intermediate" and "an ILR 3" are doing very different work.

Rocket French is more useful here, because it publishes an input rather than an outcome. Read on the same day, it advertises 138 hours of lesson time in Level 1 at $149.95, 262 hours across Levels 1 and 2 at $299.90, and 385 hours across all three at $449.85. Those are hours of material, not hours to fluency, and that is exactly why they are quotable: a claim about how much content exists can be checked, whereas a claim about how fluent you will be cannot.

The arithmetic you are actually allowed to do

There is one honest calculation available, and it is about money and material rather than months. Take the price of any course, divide it by the hours of content the vendor states, and you have a comparable number — and if the vendor states no hours, you have learned something too.

Do it with Rocket French's published figures and something appears that its pricing page does not mention: $149.95 over 138 hours is about $1.09 an hour, $299.90 over 262 hours is about $1.14, and $449.85 over 385 hours is about $1.17. The bundles are priced at exactly two and three times the single level, to the cent, so there is no bundle discount — and because each additional level adds slightly fewer hours than the first, every level you add costs a little more per hour than the one before it. That is a checkable statement about a product. "You will be conversational in three months" is not.

The other honest calculation is the one you run on yourself: how many days a week will you actually touch French? For a language whose central difficulty is recognising connected speech, contact frequency dominates total hours, because the skill is pattern exposure rather than knowledge. Twenty minutes daily beats two and a half hours on Sunday, and no product changes that. Where those minutes are best spent is the subject of what French actually charges an English speaker for, and if the goal is to compress the timeline rather than measure it, how to learn French fast, honestly covers what genuinely moves.
