How to use this calculator
- Enter your current age, the age you plan to retire, and your tax filing status.
- Enter your modified adjusted gross income (MAGI) — this decides whether you can make a full, reduced, or no Roth contribution this year.
- Enter your current Roth IRA balance, how much you plan to contribute each year, and your expected annual return.
- Open the Roth vs. Traditional section to say whether you (or your spouse) are covered by a workplace retirement plan, and enter your current and expected retirement tax rates.
- Review your eligibility, projected balance, and the after-tax comparison. The yearly table shows your balance at each age and can be exported to CSV.
How it's calculated
Your maximum contribution starts at the 2026 IRA limit of $7,500, plus a $1,100 catch-up if you're 50 or older. If your MAGI falls inside the phase-out range for your filing status ($153,000–$168,000 for single and head of household, $242,000–$252,000 for married filing jointly, $0–$10,000 for married filing separately), the limit is reduced using IRS Publication 590-A Worksheet 2-2: the reduction is proportional to how far into the range you are, the result is rounded up to the next $10, and it's never less than $200. At or above the top of the range, you can't contribute directly.
The projection adds your contribution at the start of each year and compounds your balance once a year at your expected return: balance = (previous balance + contribution) × (1 + return). If your planned contribution is above your limit, the capped amount is used.
The Traditional IRA deduction uses the 2026 phase-out ranges for people covered by a workplace plan (for example $81,000–$91,000 for single filers). If neither you nor your spouse is covered, a Traditional contribution is fully deductible at any income.
The Roth vs. Traditional comparison projects the same contributions and growth for both accounts. The Roth balance is shown as-is, since qualified withdrawals are tax-free. The Traditional balance is reduced by your retirement tax rate, since withdrawals are taxed as ordinary income. The up-front tax saving from a deductible Traditional contribution is shown separately, not invested.
Assumptions
- Contribution limits and income ranges are the IRS figures for 2026. They're held flat for future years rather than increased for inflation, and the catch-up is applied based on your current age.
- Your planned contribution, return, and income are treated as constant every year. Real returns vary, and your eligibility can change as your income changes.
- Your limit is shared across all your Traditional and Roth IRAs, and it can't exceed your taxable compensation for the year. This calculator assumes you have enough earned income and no other IRA contributions.
- Qualified Roth withdrawals generally require the account to be open 5 years and you to be 59½ or older. Early withdrawals of earnings may be taxed and penalized.
- Results are estimates for planning only and aren't tax or investment advice. Talk with a qualified tax professional about your situation.
Frequently asked questions
What is the Roth IRA contribution limit for 2026?
For 2026, you can contribute up to $7,500 across all your IRAs, or $8,600 if you're 50 or older. Your limit may be lower if your income falls in the phase-out range, and it can't be more than your taxable compensation for the year.
What are the Roth IRA income limits for 2026?
The ability to contribute phases out with modified adjusted gross income of $153,000–$168,000 for single and head-of-household filers, and $242,000–$252,000 for married couples filing jointly. If you're married filing separately and lived with your spouse at any time during the year, the range is $0–$10,000.
What is modified adjusted gross income (MAGI) for a Roth IRA?
It's your adjusted gross income from Form 1040 with a few items added back, such as deducted Traditional IRA contributions, the student loan interest deduction, and excluded foreign income. It also excludes any income from converting to a Roth IRA. For many W-2 employees, MAGI is close to AGI. IRS Publication 590-A has the full worksheet.
How is a reduced Roth IRA contribution calculated?
If your MAGI falls inside the phase-out range, your limit is cut in proportion to how far into the range you are. The result is rounded up to the next $10, and if it's more than zero but less than $200, you can still contribute $200.
Roth IRA or Traditional IRA — which is better?
It mostly depends on whether you expect a higher or lower tax rate in retirement than you pay today. A Roth is taxed now and grows tax-free. A deductible Traditional IRA saves tax now, but withdrawals are taxed later. If you expect a higher rate later, a Roth usually comes out ahead. If you expect a lower rate, a Traditional IRA usually does. Many people split contributions between both to hedge.
Can I contribute to a Roth IRA if I have a 401(k) at work?
Yes. Being covered by a workplace plan doesn't affect Roth IRA eligibility — only your income and filing status do. Workplace coverage does affect whether a Traditional IRA contribution is tax-deductible.
What if my income is too high for a Roth IRA?
You can't contribute directly, but some people make a nondeductible Traditional IRA contribution and then convert it to a Roth — often called a backdoor Roth IRA. The pro-rata rule can make part of the conversion taxable if you have other pre-tax IRA money, so review Form 8606 and talk with a tax professional first.
When can I withdraw from a Roth IRA without tax or penalty?
You can take out your own contributions at any time without tax or penalty. Earnings are tax- and penalty-free once the account has been open at least 5 years and you're 59½ or older (or meet another exception, such as disability). Other withdrawals of earnings may be taxed and hit with a 10% penalty.
What happens if I contribute more than I'm allowed?
Excess contributions are taxed at 6% for each year they stay in the account. You can avoid the tax by withdrawing the excess and any earnings on it before your tax filing deadline, or by recharacterizing the contribution to a Traditional IRA.
Does a Roth IRA have required minimum distributions?
No. The original owner of a Roth IRA never has to take required minimum distributions, so the money can keep growing tax-free for as long as you like. Beneficiaries who inherit a Roth IRA do generally have to withdraw it within a set period.
