Key Takeaways & Quick Rules

  • The 25x Rule (4% SWR): Multiply your estimated annual retirement expenses by 25 to find your baseline nest egg (e.g., $60,000/yr requires $1.5M).
  • Retirement Horizon Adjustments: Early retirees (FIRE timeline: 40+ years) should model a conservative 3.25% to 3.5% withdrawal rate (28x–30x expenses).
  • Sequence of Returns Risk (SRR): Market downturns in the first 5 years of retirement can prematurely deplete capital without a 2–3 year cash buffer.
  • Inflation Guard: Annual withdrawals must adjust for Consumer Price Index (CPI) increases to preserve real purchasing power.
