What a nest egg funds from 45
Retiring at 45 means funding 50 years to 95. The 3.5% rule of thumb says $2,285,714 covers $80,000 a year. Across 1,000 paths that nest egg lasts to 95 in 39% of them on cautious returns and 61% on Trinity-style returns. For $80,000 a year to last in 9 of 10 paths, the nest egg at 45 needs to be about $3,510,000 on Trinity-style returns and $5,820,000 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 45 with a plan to 95 is a 50-year problem. That is why the default rate here is 3.5%, not 4% borrowed from a shorter window. On Trinity-style returns, $2,000,000 supports about $45,500 a year from 45 and $47,500 from 50.

Retiring at 45 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.
