Traditional IRA Calculator

Background.

A Traditional IRA calculator projects account growth and checks whether your contribution is tax-deductible this year. The core distinction that separates a Traditional IRA from Quanta's Roth IRA calculator is timing of taxation: a Traditional IRA contribution may be deductible now, the account grows tax-deferred, and withdrawals in retirement are taxed as ordinary income. A Roth IRA works in the opposite order — you contribute after-tax dollars now, the account grows tax-free, and qualified withdrawals in retirement are tax-free. Neither is universally better; the right choice depends on whether you expect your tax rate to be higher today or in retirement, and this calculator is built to make the Traditional side of that comparison concrete with 2026 IRS figures.

The mechanic that most often confuses savers is that a Traditional IRA contribution is never blocked by income. Anyone with taxable compensation can contribute up to the 2026 limit of $7,500 (or $8,600 at age 50 or older) regardless of how much they earn — there is no MAGI eligibility cliff the way there is for a Roth IRA. What income can restrict is the deduction: if you (or, for a married couple, either spouse) are an active participant in a workplace retirement plan such as a 401(k), 403(b), or pension for the year, the IRS phases out how much of your contribution you can actually deduct from taxable income as your Modified Adjusted Gross Income rises through a specific band. For 2026, that band is $81,000 to $91,000 for Single and Head of Household filers who are covered, $129,000 to $149,000 for Married Filing Jointly filers where the IRA owner is the one covered, and a more generous $242,000 to $252,000 for a Married Filing Jointly filer whose spouse is covered but who is not personally covered by any plan themselves. If neither spouse is covered by any employer plan, the deduction is unlimited at any income level.

This calculator implements the same Worksheet-based rounding IRS Publication 590-A uses for the deduction phase-out: the partial result inside the band is rounded up to the next $10, and if that non-zero result would be less than $200, it becomes $200 instead — a small but real detail that matters for anyone landing near the edge of the range. The contribution you actually use for your retirement projection is always your full planned contribution (capped only at the statutory limit), not the smaller deductible figure, because non-deductible contributions still go into the IRA and still grow tax-deferred; they simply carry no upfront tax break, and the IRS tracks that non-deductible basis on Form 8606 so you are not taxed twice when you eventually withdraw it.

The growth side of this calculator is a straightforward illustration: it compounds your current balance and assumes the same contribution lands at the end of every year for the horizon you choose, holding your return assumption, the 2026 limit, and the phase-out inputs constant throughout. Actual future contribution limits, phase-out bands, your income, and your investment returns will all vary in reality — rerun the projection periodically as your circumstances change. Traditional IRA withdrawals before age 59½ generally trigger a 10% early-withdrawal penalty in addition to ordinary income tax, with narrow exceptions; Required Minimum Distributions apply starting at age 73 under SECURE 2.0 (see Quanta's RMD calculator). Enter your balance, age, planned contribution, expected return, horizon, filing status, workplace-plan coverage, and MAGI, then compare your deductible amount against your full contribution and the projected balance below. This is educational planning, not tax advice — confirm your actual deduction with current IRS instructions or a tax professional, especially near the edges of the phase-out range.

What is traditional ira calculator?

A Traditional IRA (Individual Retirement Arrangement) is a personal retirement account that offers tax-deferred growth and, subject to income and workplace-coverage rules, an upfront tax deduction on contributions. Money contributed and deducted today reduces your taxable income for that year; the account then grows without annual tax drag on dividends, interest, or capital gains; and withdrawals in retirement are taxed as ordinary income, because the government is collecting tax on that money for the first time. This is the mirror image of a Roth IRA, where contributions get no upfront deduction but qualified withdrawals are entirely tax-free. Anyone with taxable compensation can contribute to a Traditional IRA up to the annual limit regardless of income — for 2026 that limit is $7,500, or $8,600 including the $1,100 catch-up available starting the year you turn 50. What income and workplace-plan coverage actually restrict is the deductibility of that contribution: the IRS reduces, and eventually eliminates, the allowed deduction as Modified Adjusted Gross Income rises through a phase-out band, but only for taxpayers who are (or whose spouse is) an active participant in an employer-sponsored retirement plan during the year. A taxpayer with no workplace-plan coverage at all — and, for a married couple, a spouse with no coverage either — can deduct the full contribution at any income level. Contributions that are not deductible because of the phase-out are still allowed and still grow tax-deferred; they are tracked as after-tax basis on IRS Form 8606 so that basis is returned tax-free on withdrawal while only the earnings are taxed.

How to use this calculator.

1. 01Enter your current Traditional IRA balance.
2. 02Enter your age — 50 or older unlocks the 2026 catch-up contribution.
3. 03Enter how much you plan to contribute annually. This is never limited by income; the projection only caps it at the 2026 statutory limit.
4. 04Enter your expected annual return, e.g. 6-7% for a stock-heavy long-term portfolio.
5. 05Enter the number of years until you plan to withdraw.
6. 06Select your filing status: Single/Head of Household or Married Filing Jointly.
7. 07Select your workplace-plan coverage status — this determines which 2026 deduction phase-out band, if any, applies to you.
8. 08Enter your Modified AGI, then compare the tax-deductible amount against your full contribution and the projected balance.

The formula.

Reviewed on 2026-07-27 against IRS Notice 2025-67 and Publication 590-A. The calculator first sets the 2026 contribution limit: $7,500, or $8,600 at age 50 or older. Your contribution used in the growth projection is the lesser of your planned amount and that limit — this step has nothing to do with income. The deduction phase-out only applies if you selected workplace-plan coverage for yourself or (for Married Filing Jointly) your spouse. If neither is covered, the deductible amount equals your full contribution at any income. If you are covered, the applicable band is $81,000-$91,000 (Single), $129,000-$149,000 (Married Filing Jointly, taxpayer covered), or $242,000-$252,000 (Married Filing Jointly, only the spouse covered). At or below the lower bound, the full limit remains deductible; at or above the upper bound, the deductible result is zero. Inside the band, the reduction equals the limit multiplied by (MAGI minus the lower bound) divided by the width of the band, following IRS Publication 590-A Worksheet 1-2. That partial result is rounded up to the nearest $10, and a non-zero result under $200 is raised to $200. The deductible amount actually reported is the smaller of that phase-out result and your real contribution — you cannot deduct more than you contributed. Any remainder is non-deductible and, per Form 8606, becomes basis you recover tax-free on withdrawal. For growth, the current balance compounds by (1+r)^n and end-of-year contributions use the ordinary-annuity factor ((1+r)^n − 1)/r; at a 0% return the calculator adds contribution times years instead of dividing by zero. The projection repeats the same contribution and 2026 rules for every year even though real future limits, income, and returns will differ.
