Sustainable Withdrawal Rates
Traditional Guidelines
| Withdrawal Rate | Historical Sustainability |
|---|---|
| 3% | Very conservative, likely to grow |

| 4% | Traditional “safe” rate |
| 4.5% | Moderate risk |
| 5% | Higher risk of running out |
| 6%+ | High risk, likely to deplete |
What Affects Sustainability
| Factor | Impact |
