How long does it take to be more fluent at a language if you're at intermediate?

Anonymous

I'm at intermediate level with French and have been for the longest. My issue isn't learning from the start nor constructing sentences, nor the vocabulary nor basic verb conjugation. I already know all the basic material and sometimes can verbally say a longer conversation, involving a life event.

My issues is speaking it more fluently and faster. If I'm at intermediate and have some understanding, how long will it take to speak it fluently?

I'm talking about getting to the point of speaking French fluently (even if I have some accent, but faster without difficulty) with native speakers.
