Frequently asked questions
- What is the 4% rule?
- The 4% rule, derived from the Trinity Study, suggests you can withdraw 4% of your initial retirement portfolio per year (adjusted for inflation) with a high probability that your money lasts 30+ years.
- Can I use a different withdrawal rate?
- Yes. More conservative retirees use 3% or 3.5% (higher FIRE number). Those with other income sources or flexible spending may use 5%. Adjust the safe withdrawal rate field accordingly.
