What a nest egg funds from 50
Retiring at 50 means funding 45 years to 95. The 3.7% rule of thumb says $2,297,297 covers $85,000 a year. Across 1,000 paths that nest egg lasts to 95 in 35% of them on cautious returns and 58% on Trinity-style returns. For $85,000 a year to last in 9 of 10 paths, the nest egg at 50 needs to be about $3,550,000 on Trinity-style returns and $5,640,000 on cautious ones. Once retired, the retirement withdrawal calculator shows how many years your savings last at the spending you choose.

Why this age is different
The 4% rule was a 30-year result. Retiring at 50 with a plan to 95 is a 45-year problem. That is why the default rate here is 3.7%, not 4% borrowed from a shorter window. On Trinity-style returns, $2,000,000 supports about $47,500 a year from 50 and $52,500 from 55.

Retiring at 50 also means living on your savings before 59½, when most 401(k) and IRA withdrawals still carry a 10% penalty. The 72(t) calculator sizes penalty-free substantially equal periodic payments from an IRA, and the Roth conversion ladder calculator plans conversions you can spend five years later.
