Frequently Asked Questions

Everything you need to know.

Should I choose Roth or Traditional IRA?
Roth: if you expect to be in a higher tax bracket in retirement, you are early in career, or you want tax-free withdrawals. Traditional: if you are in a high tax bracket now and expect lower taxes in retirement, or need the deduction. Under $50,000 income: almost always Roth. Over $150,000: often Traditional.
Can I contribute to both Roth and Traditional IRA in the same year?
Yes, but the combined contribution across both cannot exceed the annual limit ($7,000 in 2026, $8,000 if 50+). Most people choose one or the other. If you cannot decide, split the contribution.
What is the Roth IRA income limit in 2026?
Direct Roth IRA contributions phase out between $150,000–$165,000 for single filers and $236,000–$246,000 for married filing jointly in 2026. Above these limits, use the backdoor Roth strategy: contribute to a non-deductible Traditional IRA then immediately convert to Roth.

Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
Does using the Roth vs Traditional IRA Calculator — Which Wins? affect my credit score?
No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.

Why This Matters

The Roth vs Traditional decision is a tax bet. Roth wins if your retirement tax rate is higher than your current rate. Traditional wins if lower. Neither is universally better — but most young earners in moderate tax brackets benefit more from Roth.
