Seems quite easy to calculate? What's your estimated cost of living per year, what's your savings rate re: your salary, what do you need to safely generate that cost of living passively based on investments until your estimated last year of life? Are there any extraordinary costs (health care in the US for example) you'd need to be responsible for after early retirement? With those numbers in hand, for most people, no, you don't retire after working 5 years at 250K per year even in an extreme low cost of savings locale.
