Well, in addition to salary, he would have also gotten a bonus and stock. The bonus might be $50K/year, and then maybe another $100K/year in stock. The number of shares in the stock grant would have been computed at the date he started -- 5 years ago, GOOG was around $440/share, so at today's price, the shares would be worth $245K/year, assuming he held onto them as they vested.
So, that adds up to around $495K/year, or maybe $300K after tax. With $50K/year in expenses, you're left with $250K/year, or $1M over 4 years.
You lose your unvested RSUs when you leave (so divide your RSU calculations by 2 to start with), and the later grants would be at higher prices and thus have experienced less growth, so your envelope math is off by enough to not be good envelope math.
On the other hand, $100k is by no means the largest RSU grant you can get, so, basically, we have no damn idea. Overall it’s pretty silly to speculate about someone’s net worth unless they’re excited to talk about it.
But the larger point that high performing senior engineers at megacorps can make way more than people outside the megacorp world imagine is true and surprisingly contoversial on HN.
those numbers are on the high side, but yes indeed.
Also all those calculations are completely forgetting that money is a time-sensitive value. If invested wisely, the first $ from 4 years ago would be 1.7$ today if invested into a typical low cost SP500
