≈ £110,000 gross a year
At a median £500/day, contract work grosses about £110,000 a year over 220 billable days, 69% more than the £65,000 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 SQL Developer contract rates and contractor take-home →
