Roth conversion optimizer:
How much to convert, and when?

A Roth conversion optimizer tests how much to move from a traditional IRA or 401(k) into a Roth, and in which years.

PortfolioPilot tests schedules that each fill your income up to the top of one tax bracket over a window of years, reruns your plan for each, and shows the best schedule it tested. It never picks one that lowers your chance of success. Part of Platinum.

How it decides

How does the Roth conversion optimizer work?

Every schedule gets the same 1,000 market paths, so only the conversions change.

One bracket at a time

Each schedule converts enough each year to fill your income up to the top of one bracket, after the standard deduction.

Taxes now, less later

Converting means paying tax now. Later withdrawals from the Roth are tax-free and lower your RMDs.

Never a lower chance of success

A schedule that lowers your chance of success is left out.

Needs pre-tax savings

With little in a traditional IRA or 401(k), there may be nothing worth converting.
