At a median £757/day, contract work grosses about £166,540 a year over 220 billable days, 85% more than the £90,000 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.
