I replaced one yesterday with close to 5000 miles on it (Dura-ace) - mostly hard miles. I do, however, clean and lube my chain after every ride. At 5000, it was close to being out of limits, but not quite there yet. As was pointed out, there are no rules of thumb. It depends on how well you care for your chain among other things. Simply measure it, and forgot about forumlas and guess work.
