Let's say payroll is half their total costs. Payroll taxes plus income taxes works out to somewhere around 40-60% of the remaining amount. Health insurance is probably in the 10% range per year, leaving them with a $50k salary. Costs are not, of course, quite that high.

As a point of comparison, a talented voice actor can gross around $125k per year, working from home as a freelancer. I don't feel that the Critical Roll actors are being overcompensated at all.
