He’s also receiving €1 million as a one-time compensation. Not quite enough to retire on that.
Damn, where is Mastodon getting €1M from? Also where do you get from that you can't retire with €1M. It seems very feasible as long as you keep a frugal lifestyle.
3% of a million is only 30k per year. A frugal person can live on that little - but it will be hard. You can make more than that working at McDonald's near me, and nobody would claim that is a living wage.
Now if you want to retire you don't need your nest egg to last forever, only until you die. You can thus withdraw a bit more than 3%, but I'm not sure how much. (and you may have other pension plans to work with). Still if you withdraw 100k/year from this million you will run out of money in less than 20 years (with 12 being realistic) 100k per year is not a great income for a programmer.
