Permanent median

Contract median
$91/hour
≈ $167,440 gross a year
At a median $91/hour, contract work grosses about $167,440 a year over 1,840 billable hours (230 days), 36% more than the $123,000 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 Backend Engineer contract rates and contractor take-home →
