The Withdrawal Rate Insight: The difference between a 4% and 5% withdrawal rate can mean 10+ years of income. The 4% rule exists because historically, a diversified portfolio could sustain that rate through most market conditions — but inflation adjustment is what makes it work. Every percentage point above 4% dramatically shortens portfolio longevity, while supplemental income from Social Security and pensions can extend it by reducing the draw on invested assets.
