The numbers are a starting point. A CFP® professional makes sense of them.

A Roth conversion can be a smart move—or an expensive one, depending on your timing, income, and tax situation. This calculator gives you the picture. A CFP® professional helps you act on it the right way, whether that means converting your retirement funds now, converting strategically over several years, or deciding the traditional account is the better fit.

The projections generated by this calculator are based on several simplified assumptions that may not reflect your actual financial situation: The calculator utilizes estimated 2025/2026 federal marginal tax brackets and simplified standard deductions and assumes a steady, annualized rate of return on your investments over the time horizon specified. Tax strategies, particularly Roth conversions, are highly complex and irrevocable once executed. You should consult with a qualified tax professional (such as a CPA) and a financial advisor to thoroughly evaluate your individual tax situation, cash flow needs, and estate planning goals before executing any strategy discussed or illustrated by this tool.
