There is a well known couple in the FIRE field named the Kaderlis who have FIREd at 35 years of age, over 30 years ago, with $500K banked. They looked at the 4% rule and showed how it would have affected them over that time. Granted, there is no guarantee that the next 30 years will have a similar market, but this shows what happened even during significant downturns like we experienced in 2008 and 2018-19. They state that they left their monies in Vanguard index funds, primarily the S&P500, and I have no reason to suspect this is not the case. Good luck on your own journey.

Variable 4%
variable 5% would have work to. As long as you can live with the swings in income.
