司令担心股市腰斩，4%只拿一半，商务舱改做经济舱。这是个误解

提上来讲一下。 问过AI

4% Rule Core Definition

• In the first year of retirement, you withdraw 4% of your total retirement portfolio balance.

• Every year after that, you withdraw the same dollar amount adjusted for inflation (not 4% of the new balance).

所以不存在腰斩的问题。

我以前有算过，过去三十年 每年拿第一年的4%（比如你有1M, 那你每年都拿4万）三十年后股市涨跌起伏。 买SPY，最后还是有一米。
