The honest answer is "it depends": on how much you study, what you already speak, and what you mean by "learn". So set those below and get a real timeline. The base figures come from the U.S. Foreign Service Institute, which puts Mongolian at about 1100 hours to professional proficiency (Category III).
Mongolian takes about 1100 hours of study to reach professional working proficiency (about CEFR C1) for an English speaker, according to the U.S. Foreign Service Institute. That places it in FSI Category III; conversational B1 arrives far sooner. This calculator turns those hours into A1 to C1 milestones and adjusts for your native language and daily study time.

Estimates only. FSI hours are measured for native English speakers in intensive classroom study; the "for you" adjustment scales them by how close Mongolian is to your native language and script. Real timelines vary with method, motivation and exposure.
Whatever your timeline, you get there quicker by meeting Mongolian in real sentences, again and again. Lingo7 lets you read real books in Mongolian with tap-to-translate and native-narrated audio. Free to start.
The base figure is the FSI study-hour estimate: how many classroom hours the U.S. Foreign Service Institute found a native English speaker needs to reach professional working proficiency. Mongolian is Category III, about 1100 hours. That number maps to roughly CEFR C1, so the earlier levels (A1 through B2) are scaled down from it using standard CEFR effort ratios.
When you pick a different native language, the total is adjusted for linguistic distance: a language in your own family branch and sharing your writing system transfers a lot and gets easier; an unrelated language with a different script gets harder. Then your daily study time turns those hours into calendar time, since the same hours spread over more minutes a day simply finish sooner.
It's an estimate, not a guarantee. What it's genuinely good at is showing that conversational Mongolian arrives much sooner than "fluent", and that steady daily contact, especially reading, is what moves the timeline.
Mongolian opens a window into the nomadic cultural heritage of Central Asia, the history of the Mongol Empire, and a unique literary tradition spanning from "The Secret History of the Mongols" to modern Mongolian literature.

For an English speaker, the U.S. Foreign Service Institute estimates about 1100 hours of study to reach professional working proficiency (roughly C1) in Mongolian, which is FSI Category III. At one hour a day that is 3 yr; conversational level (B1) comes far sooner, around 16 months. Your own pace, native language and method shift the figure, which is why the calculator above lets you adjust them.
Conversational ability (CEFR B1) takes roughly 495 hours, about 16 months at an hour a day. At B1 you can handle everyday conversations, travel independently and follow the gist of simple authentic texts. Reading real Mongolian books with parallel translation gets you there faster because you meet useful words again and again in context.
Mongolian is FSI Category III, one of the harder tiers for English speakers. Mongolian uses vowel harmony, agglutinative morphology, and a complex system of converbs (verbal forms linking clauses without subordination). It traditionally uses a vertical script written top-to-bottom, though Cyrillic is standard in Mongolia today. How hard it actually is depends heavily on the languages you already speak. A related language and shared script cut the time considerably, which the calculator reflects when you pick your native language.
Yes. The FSI hours assume classroom study; immersion and daily contact with the language compress the calendar time. The biggest levers are consistency (a little every day beats long gaps) and meeting the language in real context. Extensive reading with audio is one of the most efficient methods, because it builds vocabulary and grammatical intuition at scale.
In Mongolia, Cyrillic is the standard script used in all official contexts and education. The traditional vertical Mongolian script is used in Inner Mongolia (China) and is being gradually reintroduced in Mongolia. Most learning materials and modern literature use Cyrillic.
