5 Years: From 45 to Retired at 50
The difference between retiring at 50 and 55isn't just 5 more years of work — it's 5 fewer years of portfolio growth AND 5 more years of withdrawals. That double impact makes each year of earlier retirement exponentially more expensive.
With 5 years of accumulation starting at 45, the Power Law model projects a portfolio of $214K by age 50. However, this may not sustain $60K/year expenses long-term — the portfolio depletes at age 54.
