The Core Rule
  • Roth beats Traditional when your tax rate rises from now to retirement.
  • Traditional beats Roth when your tax rate falls from now to retirement.
  • State tax is symmetric — it cancels out and doesn't change the winner.
  • Roth has no required minimum distributions and allows early access to contributions.
  • 2025 limits: IRA $7,000/$8,000 (50+) · 401(k) $23,500/$31,000 (50+).
