The math is actually very simple.
We played two games at Walsh last season. Attendance was 1,286 and 1,219 for an average of 1,252.5. Tickets were priced at $40. That works out to just over $50,000 in revenue for each date.
My guess is we probably paid Fordham and Wagner about $50,000 for their buy rate. Halldan, SPK or someone else might have the actual number but I think that's around the low end that opponents receive for guarantee games. I would suspect -- but I don't know -- that we might negotiate a lower number for Walsh games but I doubt that makes a big difference.
We played four mon-conference games in Newark last season. Announced "attendance" (tickets sold) was 8,072, 8,606, 8,099 and 8,791 which comes out to an average of 8,392. If we use that same $40 average (which might be conservative given the variety of price points available), each game generated more than $330,000 in ticket revenue or more than six times what you made at Walsh.
Even after taking out $80,000 for rent and something north of $50,000 for the buy rate and you should be solidly in the black.
I'd say losing 75-80% of your revenue is a big hit.
