At a median £550/day, contract work grosses about £121,000 a year over 220 billable days, 70% more than the £71,000 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. Whether a contract falls inside or outside IR35 also changes how much of it you keep.
Contract and permanent benchmarks come from separate samples, so treat the gap as a guide rather than a like-for-like quote. See Data Engineer contract rates and contractor take-home →
