Forward-Looking Withdrawal Rate Insight
- The traditional 4% withdrawal rule is based on historical market data since 1926.
- Morningstar's approach is forward-looking, using market return estimates to inform safe withdrawal rates.
Conservative Withdrawal Rate Method
- Use a Monte Carlo analysis with 1000 random return paths, aiming for success in 900.
- This high success probability over 30 years ensures a conservative safe withdrawal rate estimate.
Why Withdrawal Rate Dropped
- The starting safe withdrawal rate dropped due to high recent market returns leading to higher equity valuations.
- Lower bond yields after rate cuts also imply lower future returns, prompting a downward adjustment.
