I'm very close to 50k now. Less than 3k at the moment. If all goes well, I'll reach the threshold sometime tonight. But this does not mean that my story is done. Oh no. I'll continue writing the darn thing until it is finished and I'll make myself write fast enough so that I finish by the end of the month.
I have yet to introduce the drunk monk, the evil cabal, and to explain the tentacle monster which recently ate some people and fought my main character! (Not to mention a whole host of other important plot points.)
How many more words past 50k will this take me? I have no idea.
