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 Sequence of Returns Risk.

Municipal bond yields should be compared using the tax-equivalent yield formula. In the 32% federal bracket, a 3.1% muni yield equals a 4.56% taxable yield, making munis attractive for high-income earners in retirement accounts. For more on this topic, see Emergency Fund Planning.

Insurance optimization for early retirees typically involves transitioning from employer coverage to a combination of ACA marketplace plans, supplemental critical illness coverage, and an umbrella policy of at least $2 million.

This is a bit misleading. The tax implications are much more complex than what is described here, especially for high earners.

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

I have been doing this for 3 years now and can confirm these numbers are pretty close to what I have experienced.

Can you do a follow-up article about how this applies to people with variable income? Like freelancers and consultants?
