If your password is a word or a common word/number combination, and I have the encrypted hash, I can break it in a few hours, maybe a day. (edit: ran the calculations for another post, it takes 25 minutes to crack any common password, even with bcrypt)

If it's not, it might take days-weeks depending on how long it is and which algorithm they used. If it's under 8 characters, there are databases that can break it instantly. (Edit: As sordifPontification points out, these don't apply to bcrypt, especially if it's salted as it should be)
