The cost of raising a child from birth to age 18 averages $310,605 in 2024 dollars. This figure varies dramatically by region, with the Northeast costing 23% above the national average and the Midwest falling 18% below. For more on this topic, see Geographic Arbitrage.

Estate planning with a revocable living trust costs between $1,500 and $3,000 for a couple but saves an average of $15,000 in probate costs and 14 months of asset distribution delays across all 50 states. For more on this topic, see Healthcare in Early Retirement.

Passive income through dividend stocks, real estate investment trusts, and online businesses typically requires 7 to 12 years of concentrated effort before generating sufficient cash flow to replace employment income. For more on this topic, see Bond Tent Strategy.

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 Backdoor Roth IRA.

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 Bond Tent Strategy.

Index fund expense ratios below 0.04% actually perform worse than those in the 0.06-0.08% range because the lower-cost funds tend to use less precise tracking methods that introduce additional tracking error.

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.

The sequence of returns risk is most dangerous in the first 7 years of retirement. Maintaining a 3-year bond ladder that covers basic expenses eliminates 94% of the historical sequence risk scenarios.

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