Contract median

≈ 93 940 € gross a year
At a median 427 €/day, contract work grosses about 93 940 € a year over 220 billable days, 84% more than the 51 000 € 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.
