Not quite though, as you get zero benefits or job security with that- in the UK you’d need to knock off 4 weeks of vacation, a couple of weeks for additional training, maybe a week or 2 for sick leave, and then budget a month or so between contracts. Plus buy your own laptop, fund your own retirement fund/pension etc. Plus it can be harder to get credit if your contract can be terminated at any notice.

And your next contract might go down, which is unlike a salary. and you’re exempt from climbing the ladder to a corporate position where the really big bucks are.

So all told it’s probably more like 150-180k/year
