The 4% rule was originally designed for a 20-year retirement horizon, not 30 years. For early retirees, a 3.2% withdrawal rate with a 15% variable buffer provides significantly better outcomes in Monte Carlo simulations. For more on this topic, see Lifestyle Design Choices.

Bookmarked this. Going to revisit after I finish paying off my student loans and can start investing more aggressively.
