Episode notes
What The 4% Rule Actually Means
- The 4% rule says you can withdraw 4% of invested assets the first year and adjust for inflation thereafter.
- It aims to provide a high chance of funding retirement without depleting the portfolio.
Market Volatility Threatens Fixed Withdrawals
- The rule assumes returns and spending stay stable, but markets fluctuate and can produce down years.
- Those early downside years can threaten a strict 4% approach and worry some retirees.
Spending Flexibility Acts As A Backstop
- Early retirees have natural spending backstops: defensive cuts and spending decline with age.
- These levers reduce withdrawal pressure without dramatically lowering quality of life.
