10 Years: From 40 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 10 years of accumulation starting at 40, the Power Law model projects a portfolio of $692K by age 50. However, this may not sustain $60K/year expenses long-term — the portfolio depletes at age 83.
