About Roth IRA Calculator

What Is a Roth IRA?

A Roth IRA (Individual Retirement Account) is a tax-advantaged retirement savings account established by the Taxpayer Relief Act of 1997, named after Senator William Roth. Unlike a Traditional IRA, contributions to a Roth IRA are made with after-tax dollars, meaning you pay taxes on the money before it goes in. The major benefit is that your investments grow tax-free, and all qualified withdrawals in retirement are completely tax-free — including all the investment gains.

Roth IRA vs Traditional IRA: Key Differences

Tax timing: Roth IRA contributions are after-tax (no deduction now, but tax-free withdrawals). Traditional IRA contributions may be tax-deductible (tax savings now, but withdrawals are taxed).
Required Minimum Distributions (RMDs): Roth IRAs have no RMDs during the owner's lifetime. Traditional IRAs require distributions starting at age 73.
Withdrawal flexibility: Roth IRA contributions (not earnings) can be withdrawn at any time without penalties. Traditional IRA withdrawals before age 59½ incur a 10% penalty.
Income limits: Roth IRAs have income eligibility limits ($153,000-$168,000 for single filers in 2026). Traditional IRAs have no income limits for contributions, but deductibility may be limited.
Estate planning: Roth IRAs are generally more favorable for heirs, who can inherit the account tax-free.

2026 Roth IRA Contribution Limits

Under age 50: $7,500 per year
Age 50 and older: $8,600 per year ($7,500 + $1,100 catch-up)
Single filer income phase-out: $153,000 - $168,000 MAGI
Married filing jointly phase-out: $242,000 - $252,000 MAGI

When Is a Roth IRA Better?

You are young and in a low tax bracket: Pay low taxes now, enjoy decades of tax-free growth.
You expect higher taxes in retirement: If tax rates rise or your income will be higher.
You want withdrawal flexibility: Access contributions anytime without penalties.
You want to avoid RMDs: No forced distributions means more control over your retirement income.
You are planning for heirs: Tax-free inheritance is a significant estate planning advantage.

The Power of Tax-Free Compounding

The true power of a Roth IRA becomes apparent over long time horizons. Because your investments grow tax-free, the compounding effect is amplified. For example, a 25-year-old contributing $7,500 annually at 7% returns will have approximately $1.5 million at age 65 — all of which can be withdrawn tax-free. In a Traditional IRA with the same parameters, a 22% tax on withdrawals would reduce the usable amount by about $330,000.

Frequently Asked Questions

What is a Roth IRA?

A Roth IRA is an individual retirement account where you contribute after-tax dollars. Your investments grow tax-free, and qualified withdrawals in retirement are completely tax-free. This makes it one of the most powerful tax-advantaged retirement accounts available.

What is the Roth IRA contribution limit?

For 2026, the Roth IRA contribution limit is $7,500 per year for those under age 50. If you are 50 or older, you can make an additional $1,100 catch-up contribution, for a total of $8,600 per year. These limits apply to your combined Roth and Traditional IRA contributions.

What is the difference between a Roth IRA and a Traditional IRA?

The key difference is when you pay taxes. With a Roth IRA, you contribute after-tax money and withdrawals are tax-free. With a Traditional IRA, contributions may be tax-deductible (reducing your current taxes), but withdrawals in retirement are taxed as ordinary income. If you expect to be in a higher tax bracket in retirement, a Roth IRA is generally better.

Should I choose a Roth IRA or Traditional IRA?

The decision depends primarily on your current vs. expected retirement tax rate. Choose Roth if you expect higher taxes in retirement (younger workers, rising income). Choose Traditional if you expect lower taxes in retirement (near peak earning years, planning to retire in a lower-tax state). Many financial advisors recommend having both types for tax diversification.

Can I withdraw from my Roth IRA early?

You can withdraw your Roth IRA contributions (not earnings) at any time, tax-free and penalty-free. However, to withdraw earnings tax-free, you must be at least 59½ and have held the account for at least 5 years. Early withdrawal of earnings may incur a 10% penalty plus income taxes, with some exceptions for first-time home purchase and other qualifying events.

Are there income limits for Roth IRA contributions?

Yes. For 2026, single filers can contribute the full amount if their MAGI is under $153,000, with a phase-out up to $168,000. Married filing jointly, the phase-out range is $242,000 to $252,000. Above these limits, you cannot contribute directly, but a backdoor Roth IRA conversion may be an option.
