DooWahDiddy said: "It depends, of course, on how many of those auditions are successful, since it's hard to audition while you're in rehearsal/performances (although it can be done), but I would say somewhere in the ballpark of 75-100. That works out to about twice a week, which I would say averages out because sometimes it might be three one week, but only one the following week.
Everyone is different so of course there is no "typical" (maybe it's a holiday week and there are very few auditions, maybe there's nothing right for them that week, maybe they need extra money from their day job and don't have time to audition, etc.), but I would say that's a starting point for a relatively unknown, semi-working, still-hustling actor in NY. "
Even working actors on Broadway can have two to three auditions a week. I have a friend in a hit Broadway musical who is always auditioning for things and has participated in workshops, all while cast in a show. It's not just unknown, semi-working, still- hustling actors who audition.
