Anyone who wants to know where the money went should read Mitch Weiss's "The Business of Broadway," which is a very nuts-and-bolts look at how a show is produced, budgeted, etc. To give the short version: typically about 40% of the budget is physical production costs (not just sets, but lighting, sound, costumes, wigs, etc), 6-10% on creative and production fees (composer, director, designers, music supervisors, GM, tech supervisor), 12-15% on advertising (TV, radio, print, social media) and advertising agency/press agent fees, 13-15% on production salaries (crew, company manager, crew heads, music contractor, etc), 5% on rehearsal salaries (actor salaries, stage manager salaries, payroll taxes), 8-10% on general admin (producer fees, legal, office rentals, insurance, payroll & accounting, rehearsal rentals, trucking, etc), and 10% for contingency and union bonds. The money goes VERY quickly, even for small shows. With CP, the simpler set may have led to a reduction in production costs, but not creative fees, and smaller sets & production budgets don't necessarily correlate to lower labor costs.
