The Danger Zone: Sequence of Returns Risk
Reaching your "FI Number" isn't the finish line—it's the start of the most fragile phase. Sequence of Returns Risk is the danger of a market crash happening in the first 5 years of your retirement.
Scenario A: The Crash
- Retire with $1,000,000. Withdraw $40k.
- Year 1 Market: -20%
- Portfolio drops to $760k.
- You still need $40k (now 5.2% of total!).
- Result: High risk of running out of money.
Scenario B: The Bull
- Retire with $1,000,000. Withdraw $40k.
- Year 1 Market: +20%
- Portfolio grows to $1.16M.
- $40k is now only 3.4% of total.
- Result: Likely safe forever.
Protection Strategy: Keep 1-2 years of expenses in cash/bonds (a "Cash Tent") so you don't have to sell stocks during a crash.
The Math Behind Retirement
This classic formula is derived from the 'Safe Withdrawal Rate' of 4%. The idea is that if you withdraw 4% (1/25th) of your portfolio, it should last through a 30-year retirement despite market fluctuations.
