Here's a link to the article WNG is is referencing with lots of info on wrestling club financials. the NLWC's 2015 return is there.
Here's the
2015 tax return for the SKWC. it's the only one I could find.
for comparison's sake, in 2015 the NLWC reported revenue of 372,072 and expenses of 630,283, with what looks like 313,512 going to coaches.
In 2015, the SKWC raised 117,556 and spent 90,919, with 64,301 going to coaches. In both instances I'm assuming the coaches are the post collegiate resident athletes.
SKWC had 52,351 in net assets at the end of their fiscal 2015. NLWC had 5,740,114.
Haven't been able to find every tax return yet (and some clubs may not be non-profits and might not have publicly available returns) but I'd guess SKWC is the top 20 in funds raised but pretty far off from the top 5.
