Safe Withdrawal Rate

The safe withdrawal rate is the percentage of your portfolio you can spend each year without running out of money over a 30-year retirement. The widely cited "4% rule" comes from the Trinity Study, which found that a 4% initial withdrawal rate (adjusted for inflation) survived nearly all historical 30-year periods. It's a starting point, not gospel — your actual rate depends on asset allocation, spending flexibility, and market conditions.
