Is 4% a safe withdrawal rate for 30 years?

A 4% withdrawal ($40k a year from $1M, raised with inflation) lasted 30 years in 96% of start years since 1871 with a 60/40 portfolio, and 96% with 100% stocks.

It almost always lasted: the money ran out in 5 of 124 start years from 1871 to 1994. Failures clustered in start years 1965–1969.

The worst start was 1966, when the money ran out in year 25. Among the start years that lasted, 1964 came closest, finishing with $12k.

In 57% of start years the portfolio ended above the $1M it started with, after inflation. The median ending balance was $1.2M.

Cutting spending by 20% whenever the portfolio sat more than 20% below its real high raised success to 100%. Holding two years of spending in cash and drawing on it after down years lowered it to 94.4%.

Of the four mixes, 80/20 lasted most often, at 96.8%.

By portfolio and strategy

Success is the share of start years in which the money never ran out. Endings are for the fixed strategy, in today's dollars. 20% cut in bear markets: spending drops 20% while the portfolio is more than 20% below its inflation-adjusted high. 2-year cash bucket: two years of spending held in cash earning 0.5% real, spent after years when stocks fell and refilled after years they rose.
