Roth IRA vs Traditional IRA
Free calculator + plain-English explanation. No signup required.
See all calculators →The choice between Roth and Traditional IRA is one of the most consequential personal finance decisions — a $6,000/year contribution over 30 years compounds to roughly $750,000 at 8% annual return. The tax treatment difference between Roth and Traditional can mean $100K+ in lifetime tax difference. Here is the framework.
Quick comparison
| Traditional IRA | Roth IRA | |
|---|---|---|
| Contributions | Pre-tax (deduct from current income) | After-tax (no current deduction) |
| Withdrawals in retirement | Taxed as ordinary income | Tax-free |
| 2026 contribution limit (under 50) | $7,000 | $7,000 |
| 2026 contribution limit (50+) | $8,000 | $8,000 |
| Income limit (single, full contribution) | None | $150,000 (2026 est) |
| Income limit (single, partial) | None | $150,000-$165,000 |
| RMDs (Required Minimum Distributions) | Yes, at age 73 | NO — never required during owner's life |
| Early withdrawal penalty | 10% before 59½ | 10% on earnings only; contributions can be withdrawn anytime |
The decision framework: current vs future tax bracket
The single most important factor: will you be in a higher or lower tax bracket in retirement than you are now?
- If you expect to be in a HIGHER bracket in retirement (e.g., young professional with growing income, or someone with large taxable accounts that will throw off income): use ROTH. You pay tax now at the lower rate, withdraw tax-free later at higher rate.
- If you expect to be in a LOWER bracket in retirement (e.g., late-career high earner planning to retire to lower-income lifestyle): use TRADITIONAL. Deduct now at high rate, pay later at lower rate.
For most people in their 20s-30s, ROTH wins. For most people in their 50s-60s peak earning years, TRADITIONAL wins.
When Roth is unambiguously better
- You're in your 20s and current income is below your eventual peak
- You expect to receive Social Security + pension + RMDs — those are taxable income that will push you into higher brackets
- You want to leave money to heirs (Roth has no RMDs; can grow tax-free for decades)
- You expect tax rates to rise (the 2017 tax cuts expire end of 2025; rates may revert higher)
- You want flexibility to withdraw contributions before 59½ without penalty
When Traditional is unambiguously better
- Current marginal tax bracket is 32% or higher
- You're close to retirement and expect significantly lower income post-retirement
- You need the immediate tax deduction to stay below an income threshold (e.g., to get ACA subsidies)
- You're a high-income earner already maxing 401k and Backdoor Roth ineligible
Backdoor Roth IRA strategy
If your income exceeds Roth contribution limits, the "Backdoor Roth" lets you still contribute:
- Make a non-deductible contribution to Traditional IRA ($7,000 for 2026)
- Convert the Traditional IRA balance to Roth IRA
- Pay tax only on any earnings between contribution and conversion (usually minimal if done quickly)
Caveat: pro-rata rule — if you have other Traditional IRA balances, conversion is taxed proportionally. Consult a CPA.
What about 401k vs IRA?
If your employer offers a 401k with match: max the match first (it's a 50-100% return on contribution). Then decide between Roth IRA, Traditional IRA, or back to 401k:
- If 401k has good investment options: continue contributing past the match
- If 401k has high fees or limited options: use IRA for additional retirement savings
- If your employer offers Roth 401k AND Traditional 401k: the same logic applies — high earner now → Traditional 401k; expect higher bracket later → Roth 401k

- Can I contribute to both Roth and Traditional IRA?
- Yes, but the COMBINED total can't exceed the annual limit ($7,000 in 2026, $8,000 if 50+).
- What's the income limit for Roth IRA in 2026?
- For single filers: full contribution under $150,000 MAGI; partial $150,000-$165,000; none above $165,000. Married filing jointly: full under $236,000; partial $236,000-$246,000; none above $246,000.
- Can I convert Traditional to Roth (Roth conversion)?
- Yes, anytime, regardless of income. You pay income tax on the converted amount in the year of conversion. Strategic conversions in low-income years (early retirement, sabbatical) can save lifetime tax.
- What happens to my Roth IRA when I die?
- Heirs (other than spouse) must withdraw within 10 years of inheriting. Tax-free withdrawals for the inheritor. Spouse can roll into their own IRA and treat as their own.
- Are 529 plans better for kids than Roth IRA?
- Different purposes. 529 = education only (with penalty for non-education use); Roth = retirement primarily. Some advisors favor Roth for the FIRST $7K of annual savings since it's flexible — kids can use for retirement, education, first home, or emergency.
Educational only — not legal, financial, or tax advice. Tax law and rates change frequently. Consult a CPA or financial advisor for your specific situation.
