What is Roth IRA vs Traditional IRA?
The Roth vs Traditional IRA decision depends primarily on whether you expect your tax rate to be higher or lower in retirement compared to today. If you expect higher taxes later (early career, rising income), Roth is typically better — pay taxes now at a lower rate and enjoy tax-free withdrawals later. If you expect lower taxes in retirement, Traditional is typically better — take the deduction now and pay taxes at a lower rate later. This calculator models both scenarios with your specific numbers.
Which is Better for You?
The right choice depends on your specific situation. Here are the most common decision scenarios:
You expect higher income (and tax bracket) in retirement
Pay taxes now at a lower rate. Roth withdrawals are tax-free, so you avoid paying higher rates in retirement.
You're in a high tax bracket now and expect lower in retirement
The upfront tax deduction saves more now. You'll pay taxes on withdrawals at a lower retirement rate.
You're young and early in your career
Decades of tax-free compound growth is enormously valuable. Your current lower tax bracket makes the Roth conversion cost minimal.
You want no Required Minimum Distributions (RMDs)
Roth IRAs have no RMDs during the owner's lifetime. Traditional IRAs require withdrawals starting at age 73, which can push you into higher tax brackets.

Frequently Asked Questions
What is the main difference between Roth and Traditional IRA?
Traditional IRA: contribute pre-tax money (tax deduction now), pay taxes on withdrawals in retirement. Roth IRA: contribute after-tax money (no deduction now), withdrawals are completely tax-free in retirement. The key question is whether your tax rate is higher now or in retirement.
What is the IRA contribution limit?
For 2026, the annual contribution limit is $7,000 for those under 50, and $8,000 for those 50 and older (the extra $1,000 is a catch-up contribution). This limit applies to the total across all your IRAs — not per account.
Can I have both a Roth and Traditional IRA?
Yes, you can contribute to both in the same year. However, the total combined contribution cannot exceed the annual limit ($7,000/$8,000). Many financial advisors recommend having both for tax diversification in retirement.
What are the income limits for Roth IRA?
For 2026, single filers can contribute the full amount if MAGI is under $150,000 (reduced contribution up to $165,000). Married filing jointly: full contribution under $236,000 (reduced up to $246,000). There are no income limits for Traditional IRA contributions, but deductibility may be limited.
Which IRA is better for young professionals?
Generally Roth, for three reasons: (1) you're likely in a lower tax bracket now than you will be later, (2) decades of tax-free compound growth is extremely valuable, and (3) Roth contributions (not earnings) can be withdrawn penalty-free if needed. The earlier you start a Roth, the more powerful the tax-free growth.
