Sure! You could've kept working! Why did you retire?
I'm curious how off my estimations are :)
The tech sector stock growth has been amazing/unprecedented over that time period. His first few years of stock grants have tripled or more in value.
I'm betting it's something like $2.6mm. $1.5mm in saved income, $0.8 in stock appreciation on savings, and $0.3 in housing/misc.
Average TC: $450k - $850k
Post-tax: $270k - $470k
Annual expenses: $60k - $120k
Savings: $1.2m - $3.3m
Obviously this is a gross simplification, since it ignores other investments and makes pretty broad assumptions about their expenses, but it should give you the broad strokes.
