Frequently asked questions

The share of a portfolio you can take each year without running out. The classic answer is 4%, though many planners now suggest 3-3.5%.
Low expected returns and long retirements. The original study assumed 30 years and historical US data; 40-year retirements need a lower rate.
Sequence risk is the real threat. A bad first decade plus fixed withdrawals can exhaust a portfolio even if average returns look fine.
