A 56-year-old who retired early in Miami sits in a rare low-income window: no salary, no Social Security yet, $1.8M — but $1.4M of it is trapped in a pre-tax 401k. Converting $65k per year to Roth now fills lower tax brackets cheaply, slashes future RMDs, and may save hundreds of thousands in lifetime taxes.
The earliest retirement age at which this plan does not run out of money is 57, after 1 more year of full-time work. No age tested reaches 80% success in the Monte Carlo simulations, so the plan depends on favorable markets.

EARLIEST POSSIBLE: Retire at Age 57 Switch to semi-retirement at age 57 (after 1 high-salary years). Portfolio bridges to full retirement at 57.
Growth rate (4.0%) keeps compounding during spending — the extra buffer matters most against bad early-retirement market sequences.
Social Security: $38k/yr starting at age 70 is included. Healthcare: $18k/yr before Medicare at 65. Roth Ladder: converti
Across the simulated market histories (in future dollars, not adjusted for inflation), the median portfolio is $628k at 70, $655k at 80, $455k at 90. In a poor sequence of returns (10th percentile) it is $0k at 70, $0k at 80, $0k at 90.
