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.

Target = Annual Expenses × 25
TargetYour 'FI Number' (Financial Independence)
Annual ExpensesAmount you spend per year to live comfortably
25Inverse of 4% (1 / 0.04 = 25)

Example: The Power of Compound Interest

Why starting early matters more than saving more.

1
Person A
Invests $500/mo for 10 years, then stops. Total invested: $60,000.
Starts at 25
2
Person B
Invests $500/mo for 30 years until 65. Total invested: $180,000.
Starts at 35
3
The Result
Despite investing 3x less money, Person A ends up with more money at age 65 due to the extra 10 years of compounding on the initial sum.
Person A Wins

Frequently Asked Questions

Should I include Social Security?
This calculator focuses on your personal portfolio. Social Security is usually treated as a reduction in your "Annual Expenses" need. For example, if you need $80k and SS pays $30k, you only need your portfolio to generate $50k.
What is a good savings rate?
A common suggestion is 15-20% of your gross income. However, for early retirement (FIRE), savings rates of 40-60% are standard.
