≈ $188,100 gross a year
At a median $855/day, contract work grosses about $188,100 a year over 220 billable days, 19% more than the $158,000 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.
