Roth vs Traditional IRA Calculator: Compare & Decide 2026

You’re facing a $50,000+ decision that most people get wrong: Should your retirement savings go into a Roth or Traditional IRA?

Here’s the reality: In 2026, choosing the right account type could save you $50,000+ in taxes over 30 years. The wrong choice? It costs you.

This guide cuts through the confusion with a practical framework showing exactly when Roth wins, when Traditional wins, and the 2026 tax law changes that changed the math. If you’re over $150K income, have existing retirement accounts, or are planning to retire early, this is critical.

Let’s walk through the exact decision tree so you know which IRA strategy fits YOUR situation in 2026.

Before you make any decisions, here’s what’s different in 2026:

  • Contribution Limits Increased: $7,500/year (under 50), $8,600 (age 50+) — up from $7,000/$8,000 in 2025
  • Roth Income Limits: Single $151K-$166K (phase-out range), Married Filing Jointly $237K-$247K
  • RMD Age: Still 73 for most, but increases to 75 starting in 2034
  • 529-to-Roth Rollovers: Expanded access for rolling unused 529 plans into Roth IRAs
  • Last-Stretch Catch-Up: New $1,000/year catch-up for ages 60-63 (on top of age-50+ catch-up)

The Pro-Rata Rule: Why Your Existing IRA Might Block Your Backdoor Roth

This is THE most misunderstood rule in retirement planning, and it trips up high earners constantly.

Simple version: If you have ANY money in a Traditional IRA (including old 401k rollovers), the IRS treats all your Traditional IRAs as ONE bucket when converting to Roth. You get taxed on the FULL percentage of pre-tax money, not just what you’re converting.

The problem: This can wipe out the backdoor Roth benefit.

Real example: You make $200K with $150K in a Traditional IRA (old rollover). You try a $7,500 backdoor Roth. The IRS looks at $157,500 total (98% pre-tax). You pay ~$1,500 in taxes to move just $7,500. Not worth it.

The FIX: Roll the $150,000 Traditional IRA into your employer’s 401(k) FIRST (if allowed). Now pro-rata rule doesn’t apply. Your backdoor Roth becomes completely tax-free.

Why it matters: If you make $151K+, income limits block direct Roth contributions. Backdoor Roth is often your ONLY path. But pro-rata rule can kill it.

Which IRA Should YOU Choose? Your Decision Tree

Under $75K income? Choose Roth. You’re in a low tax bracket now. Paying 12% tax today to grow tax-free for 30+ years is smart math.

Making $75K-$120K? Choose Traditional OR split both. The 22% deduction helps now. But ALSO fund Roth if possible to hedge tax rate risk.

Making $120K-$150K (single) or $200K-$237K (married)? Go hard on DIRECT Roth contributions NOW. This is your window before income limits block you. Once you cross $151K/$237K, backdoor Roth becomes necessary (more complex).

Making $150K+ or $237K+ (married)? Your ONLY path is BACKDOOR ROTH. Contribute to non-deductible Traditional IRA, then immediately convert to Roth. BUT: Check for pro-rata trap first (see section above). Also maximize employer 401(k) as secondary tax-deferred savings.

Retiring in 5 years or early (before 59.5)? Choose ROTH. You can access contributions anytime without penalty. Traditional IRA locks you in until 59.5 unless you use 72(t) rule.
