At a median $94/hour, contract work grosses about $172,960 a year over 1,840 billable hours (230 days), 37% more than the $126,000 permanent median. That premium has to pay for what an employer would otherwise cover: paid holiday and sick days, pension contributions, and the gaps between contracts. Contract and permanent benchmarks come from separate samples, so treat the gap as a guide.
