lets make it simple...
an employee, to any company, costs around 150-200% of they salary they pay depending on the level of benefits... so PTO, Medical, Dental, Vision, Life, Pension, Stock Options, Retirement Plans, Restricted Stock Units, Social Security Match, Unemployment, bonuses, etc... all those are company expenses... so you can assume that $100K is more like lets say $200K to the company... and it all comes from GROSS REVENUES... it is all an expense... some smaller companies might have profit sharing, not all... even that profit sharing will be an expense, unless you are a partner, then that is a different story because then, you are getting a piece of the actual "profit"..
