Frequently asked questions
- What is the 4% rule?
- Research suggests retirees can withdraw 4% of their portfolio in year one, then adjust for inflation annually, with a high probability of the portfolio lasting 30+ years. It's a useful estimate, not a guarantee.
- What return rate should I assume?
- A diversified stock/bond portfolio has historically returned 6-7% after inflation over long periods. Use 5-7% for planning; stress-test with 3-4%.
