≈ 70 840 € gross a year
At a median 322 €/day, contract work grosses about 70 840 € a year over 220 billable days, 69% more than the 42 000 € 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.
