Roth Conversions: Social Media Advice Misses the Math
Roth conversions are everywhere right now. Scroll financial media long enough and you’ll hear the same refrains:
“Taxes are going up.”
“Convert to fill your tax bracket.”
“Pay tax once, never again.”
Sometimes that advice is correct. Most of the time it’s incomplete, untested, or bad advice.
Tax-rate arbitrage is one variable in the decision, and arguably not the most important. You’re paying tax today to avoid tax tomorrow. Nevertheless, it requires sound math.
One common error is ignoring lost compounding on the tax payment itself. When you convert, you send money to the IRS that could otherwise remain invested. Over 15–20 years, that opportunity cost can be substantial.
Another error is assuming static tax brackets. Real tax brackets adjust for inflation. Most conversion software treats tax rates as a fixed variable. Required minimum distributions and legislative changes muddy the water. Roth conversion advice isolated from a sound retirement income plan could be hard on your assets.
Goals matter. Are you solving for most assets for you and your spouse, or for your beneficiaries? Estate wealth transfer should be included in your Roth conversion analysis.
Conversion decisions work best when the analysis is comprehensive and connected to the plan. ‘Free’ online calculators are woefully inaccurate and paint an incomplete picture.
Closing Thought:
Before executing a large conversion, run the numbers using accurate software and across multiple scenarios and longevity. Decide your purpose: total assets for income or wealth transfer. If you want a disciplined, math-first review of whether a conversion improves your long-term outcome, performed by a Certified Roth Conversion Specialist (CRCS), reply and let us know.
