Roth IRA Calculator 2026 — Tax-Free Growth & Contribution Limits

How Roth IRA Calculator Works

FV = CurrentBalance × (1+r)^n + Contribution × [(1+r)^n − 1] / r

Future Value formula with annual contributions, where r = annual return rate and n = years to retirement. The result is 100% tax-free at withdrawal — unlike traditional IRAs or taxable accounts. For 2026: contribution limit = $7,500 (under 50), $8,600 (age 50+).

Contribution Limits

2026 Roth IRA Max Contributions — Under 50: $7,500/year. Age 50+: $8,600/year (includes $1,100 catch-up). Limits apply to combined contributions across all IRA accounts (Roth + Traditional).

Tax-Free

The Core Advantage — Roth IRA contributions are made with after-tax dollars. All growth and withdrawals in retirement are completely tax-free (assuming age 59½+ and 5-year rule met). On a $1M Roth balance, a 22% withdrawal tax rate would cost $220,000 in a traditional IRA. With a Roth: $0.

Income Limit

Phase-Out Range — For 2026: Single filers earning $150,000–$165,000 face a reduced contribution limit. Above $165,000, direct Roth IRA contributions are not allowed. Married filing jointly: $236,000–$246,000 phase-out. Alternative: the "Backdoor Roth IRA" strategy (contribute to traditional IRA, then convert).

How to Use

1. Enter your current and target retirement age to set the investment window.
2. Enter your current Roth IRA balance (0 if starting fresh) and planned annual contribution.
3. The calculator automatically flags contributions exceeding 2026 IRS limits ($7,500 under 50, $8,600 age 50+).
4. Select your marginal tax rate to see the tax savings vs. a taxable account or traditional IRA.
5. The pie chart shows the split between your contributions and tax-free growth.

Common Uses

• •Project the tax-free growth of a Roth IRA over time to see how contributions and compound returns build a retirement nest egg.
• •Compare Roth IRA versus traditional IRA or taxable account growth to determine which account type maximizes your after-tax retirement income.
• •Plan your annual contribution strategy to maximize the Roth IRA limit and understand the long-term value of tax-free withdrawals in retirement.

Understanding the Result

The Roth IRA is the most tax-efficient retirement account available to most Americans. You pay taxes now (on contributions) and never again — not on growth, not on withdrawals. The tax-free compounding advantage grows exponentially: on a $7,500/year contribution at 7% for 35 years, your contributions total roughly $263K while your tax-free balance reaches over $1M. The 100%+ of the final balance that represents earnings — all untaxed at withdrawal — is the Roth IRA's irreplaceable value proposition.

Frequently Asked Questions

What are the 2026 Roth IRA contribution limits?

For 2026: The base contribution limit is $7,500 per year for individuals under age 50. Those 50 and older may contribute an additional $1,100 (the catch-up contribution), for a total of $8,600/year. This limit applies to combined contributions across all IRA accounts (Roth + Traditional combined cannot exceed these limits).

What are the income limits for Roth IRA contributions?

For 2026: Single filers with MAGI above $165,000 cannot contribute directly to a Roth IRA. The phase-out begins at $150,000. For married filing jointly, the phase-out is $236,000–$246,000. If you exceed these limits, consider the "Backdoor Roth IRA" strategy: contribute to a non-deductible traditional IRA, then convert it to Roth.

Roth IRA vs. Traditional IRA: which is better?

If you expect to be in a higher tax bracket in retirement than you are now — choose Roth (pay low taxes now, avoid high taxes later). If you expect to be in a lower bracket in retirement — Traditional may be better (deduct contributions now at high rate, pay lower rate later). If you are unsure, contributing to both (up to the combined limit) provides flexibility.

Can I withdraw Roth IRA contributions early?

Yes — Roth IRA contributions (not earnings) can be withdrawn at any time, at any age, without tax or penalty. This makes the Roth IRA a flexible emergency backup as well as a retirement account. However, withdrawing earnings before age 59½ (or before the 5-year rule is met) typically triggers taxes and a 10% penalty.

What is a Backdoor Roth IRA?

A Backdoor Roth IRA lets high earners who exceed the income limits contribute indirectly: make a non-deductible Traditional IRA contribution, then convert it to Roth. If you have no existing pre-tax Traditional IRA balance, the conversion is nearly tax-free. The SECURE Act 2.0 also introduced Roth SEP and Roth SIMPLE IRA options for self-employed individuals.
