Retiring in 1977: did the 4% rule survive?

Retiring at the start of 1977 with $1M and spending $40,000 a year adjusted for inflation (the 4% rule), a 100% stock portfolio lasted all 30 years, with $3.9M left; a 60/40 portfolio lasted all 30 years, with $2.2M left.

Over the first 10 years, stocks returned 7.6% a year after inflation and the 60/40 mix 6.1%. The first decade matters most: losses early, while withdrawals continue, are what break a plan.

The highest fixed rate that lasted 30 years from 1977 was at least 6% with either all stocks or 60/40 (tested in 0.25% steps from 3% to 6%).
