Average ticket price is usually a better indicator of a show's financial health than percentage of capacity.
Looking at Drowsy, for example, as ThankstoPhantom mentioned, it made over $908,802 last week playing to 79% capacity. That may seem like a low percentage, but its average ticket price was a robust $89.27, which means that it is not using a lot, if any, discounts right now, and most people must be seeing it for full price. The big hits, like Jersey Boys, Wicked and The Lion King have average ticket prices in the $90 and $100 range.
The long running shows like Phantom, Beauty, Hairspray and The Producers are subsisting on discounted tickets, with most of them garnering an average ticket price between $65-$70.
With that as a guideline, it’s not completely healthy for The Wedding Singer to already be playing with an average ticket price of $69.43, and not very good for Dirty Rotten Scoundrels to be averaging $63.11 a ticket, just above the long-running Rent.
Begin at the beginning and go on till you come to the end: then stop.
