The 4% Rule: Understanding Sustainable Withdrawal Strategies
Key Takeaways
- The Golden Rule: Withdraw 4% of your nest egg in Year 1, then adjust for inflation annually. Historically, this lasts 30 years.
- Not Guaranteed: It’s a rule of thumb, not a law of physics. Market crashes early in retirement can break the rule.
- Flexibility is Key: Being willing to skip an inflation adjustment during bad years can drastically improve success rates.
Determining a sustainable retirement withdrawal rate is essential for long-term financial planning. The 4% Rule, widely discussed since the Trinity Study, offers a structured way to estimate initial withdrawals while considering inflation and market variability.
Basic Idea: If you have $1,000,000 saved, you withdraw $40,000 in the first year. If inflation is 3%, you withdraw $41,200 the next year. Simple, but effective.
How Withdrawal Adjustments Work
| Year | Description | Example ($1M Start) |
|---|---|---|
| Year 1 | Withdraw 4% of the initial balance. | $40,000 |
| Year 2 | Adjust prior-year withdrawal for inflation (3%). | $41,200 |
| Year 3+ | Continue adjusting for CPI each year. | Inflation-adjusted amounts |
Historical Success Rates (Illustrative)
Studies evaluating U.S. market performance suggest higher success probabilities at lower withdrawal rates. These values are simplified for demonstration and may vary depending on the portfolio’s asset allocation.
Key Considerations for Using the Rule
1
Check Your Asset Allocation
The 4% Rule assumes a balanced portfolio (e.g., 50% stocks / 50% bonds). If you are 100% in cash or 100% in crypto, this rule does not apply.

Mind the Sequence Risk
If the market crashes 20% the year you retire, the 4% Rule becomes risky. Consider a lower rate (3.5%) or a dynamic spending plan.

A Guideline, Not a Law
Use 4% as a starting point for planning, but be ready to adjust based on actual market conditions and your life expectancy.
