Permanent median

Contract median
646 €/day
≈ 142 120 € gross a year
At a median 646 €/day, contract work grosses about 142 120 € a year over 220 billable days, 89% more than the 75 000 € 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 rather than a like-for-like quote. See AI Research Scientist contract rates and contractor take-home →
