Retiring at 45 — The Reality

Retiring at 45 requires a portfolio of ~$0.8M to sustain a standard 4% withdrawal rate over a 20-year horizon. You have 20 years of accumulation runway if you start now.

Strategy for Retiring at 45

  1. Sequence-of-returns risk is real: A market crash in the first 5 years of retirement can permanently impair your portfolio. Consider a Bond Tent, lower initial withdrawal rate (3.0-3.5%), or Guyton-Klinger guardrails.
  2. Healthcare bridge to Medicare: You have 20 years before Medicare eligibility. Budget $15-25K/year for ACA marketplace premiums if retiring before 65.
  3. Social Security timing: Each year you delay past 45 increases your benefit by 8% (until 70). Delaying can be worth $100K+ in lifetime benefits.
  4. Withdrawal strategy: With a 20-year horizon, the 4% rule is conservative. Consider 3.5% starting rate for safety, or 3.7% if you have flexibility.
  5. Roth conversions in low-income years: Early retirement creates a unique window to convert traditional IRA money to Roth at low tax rates — potentially saving $50-200K in lifetime taxes.
