Permanent median
$139,000
$96,330 take-home
Contract median
$105/hour
≈ $193,200 gross a year
At a median $105/hour, contract work grosses about $193,200 a year over 1,840 billable hours (230 days), 39% more than the $139,000 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 Site Reliability Engineer (SRE) contract rates and contractor take-home →
