Conversion looks beneficial

Converting $50,000 at your 22% marginal rate costs $12,805 in taxes today. By retirement, this saves you $29,762 compared to paying taxes later at your expected 22% rate. Even at the same tax rate, converting now locks in today's rate and lets your money grow tax-free in a Roth — no RMDs, no future tax surprises.

Understanding Roth Conversions

When Conversions Make Sense

  • Lower current tax rate — you expect a higher bracket in retirement
  • Long time horizon — more years of tax-free growth increase the benefit
  • Estate planning — Roth IRAs have no Required Minimum Distributions
  • Gap years — low-income years (early retirement, sabbatical) are ideal

Key Considerations

  • Pay taxes from non-retirement funds
  • Watch IRMAA thresholds if 63+
  • Multi-year strategies stay in lower brackets
  • Factor in your state tax rate
