The Meaning of Financial Independence
Financial independence occurs when income generated by invested assets covers 100% of your annual living expenses, rendering traditional wage labor optional. Achieving this milestone requires calculating your target portfolio size based on proven withdrawal frameworks.
The 4% Rule and Trinity Study
Derived from the Trinity Study, the 4% rule demonstrates that a diversified portfolio of 50-75% equities and 25-50% bonds historically survived a 30-year retirement period without exhaustion in over 95% of past historical backtests.
Calculating Your Target Portfolio
Divide your expected annual expenses by 0.04 (or multiply by 25). If your annual expenditure is $50,000, your target nest egg is $1,250,000. For longer horizons exceeding 30 years, adopting a conservative 3.25% to 3.5% withdrawal rate provides an added safety cushion against sequence of returns risk.
