Question 1

What is a Roth conversion ladder?

Accepted Answer

A Roth conversion ladder is a multi-year strategy where you convert a portion of a Traditional IRA or 401(k) to a Roth IRA each year, paying ordinary income tax on the converted amount. Each year's conversion is its own 'rung' that becomes available for penalty-free withdrawal exactly five years later under the 5-year rule. By stacking rungs, early retirees can build a tax-free, penalty-free income stream from age 59½ — and even before via the conversion-rung mechanism.

Question 2

What is the 5-year rule for Roth conversions?

Accepted Answer

Each Roth conversion has its own 5-year clock. The converted principal becomes available for penalty-free withdrawal five tax years after the conversion, regardless of your age. This is why early retirees stagger conversions over multiple years — each annual conversion creates one rung of the ladder that becomes accessible five years later.

Question 3

When is a Roth conversion most tax-efficient?

Accepted Answer

Conversions are most efficient in low-income years — early retirement before Social Security and RMDs, sabbaticals, gap years, or after a layoff. The strategy is to convert just enough to fill up a low marginal bracket (often the 12% or 22% bracket) without spilling into a higher one. This calculator's fill-to-bracket mode automates that calculation.
