The 4 Percent Rule Fails When Longevity Runs Long

Most FIRE plans treat retirement as a fixed 30-year horizon. But what happens when you actually live to 95 or 100? In this episode, Lucas and Luna dig into the longevity risk that most early retirees ignore: the probability that your portfolio outlives you, and the surprisingly simple math that shows why a 4 percent withdrawal rate might not be enough for a 50-year retirement. They walk through the Trinity study's original assumptions, the concept of 'failure rate' versus 'poverty rate', and why a flexible spending rule — like the guardrails approach — can cut your risk dramatically without sacrificing lifestyle. Along the way, they share a striking example: a retiree who spends just 10 percent less in bad years can reduce the chance of running out of money by half. If you're planning a FIRE timeline longer than 40 years, this episode is your wake-up call. #FIRE #FinancialIndependence #RetireEarly #LongevityRisk #4PercentRule #WithdrawalRate #TrinityStudy #Guardrails #RetirementPlanning #EarlyRetirement #PortfolioSurvival #SequenceRisk #Finance #WealthManagement #RetirementMath #FexingoBusiness #BusinessPodcast #PersonalFinance Keep every episode free: buymeacoffee.com/fexingo
