How much money would it take for you to comfortably quit your job permanently, if you won the lottery?

This morning on the news they were showing the “Ocean 16” which is 16 employees of a New Jersey municipality who, together, won $86 million in the lottery. After taxes, it amounts to about a little less than than 4 million each, total.

I was thinking if I’m alive for four more decades (as I’m in my mid-forties), 4 million would be $100,000 per year, which would be enough to quit work now with. I would probably invest it, so it would (hopefully) snowball.

What kind of lottery winnings would it take for you to quit, money-wise?
