The answer on these inputs
$90,000 a year at 4.0% needs $2,250,000 at age 60. Starting from $1,100,000 and adding $30,000 a year at 5.0% real, the portfolio at 60 is $2,169,121 — short by $80,879. Across 1,000 seeded paths, that projected nest egg funds the spend for 35 years in 38% of worlds.

Why this age is different
The 4% rule was a 30-year result. Retiring at 60 with a plan to 95 is a 35-year problem. That is why the default rate here is 4.0%, not 4% borrowed from a shorter window. Sibling pages for the other ages:
