Is that $500/h freelancer/contractor fee? Because that seems absurdly high for someone on a payroll no matter how much of a rockstar they are. If so, then you have to factor in all the non-billable hours you spend getting clients/contracts, advertising, and general housekeeping required to run a company. Then stuff like health care, car, phone, computer, electricity, office and other expenses. Just saying that you can't just say: "my time is worth $500/hr" if that's what you bill for 4 hours a day for a client for few weeks.
