Traditional IRA Calculator

A traditional IRA flips the Roth trade: you deduct contributions now and pay income tax later, when you withdraw. Project the pre-tax balance your contributions could reach, see the tax deduction you'd claim this year, and estimate what's left after retirement taxes — all against the 2026 contribution limit of $7,500.

2026 limit: $7,500 ($8,600 with the age-50+ catch-up).

The rate on your last dollar of income — sets how much each contribution saves in tax.

The effective rate you expect on withdrawals. Often lower than today's, since retirement income is usually lower.

How this calculator works

Contributions are spread monthly and compounded at your expected return in exact cents — the same tax-deferred growth as any pre-tax account. 'Tax-deferred growth' is the projected balance minus everything you contributed.

The tax deduction is your contribution times your marginal rate today. The withdrawal tax applies your estimated retirement rate to the whole projected balance — a planning simplification: real withdrawals are spread across years and stack progressively through the brackets, so treat 'after-tax value' as a directional estimate, not a filing figure.

The 2026 limits come from IRS Notice 2025-67 (verified July 2026). Deduction phase-outs (for those covered by a workplace plan) and RMDs are not modeled. This is an educational projection, not tax advice.

Frequently asked questions

How much can I contribute to a traditional IRA in 2026?

$7,500 for 2026, plus a $1,100 catch-up if you're 50 or older (IRS Notice 2025-67). That limit is shared across all your traditional and Roth IRAs combined — it's a single bucket, not one each — and you need earned income at least equal to your contribution.

Is my traditional IRA contribution tax-deductible?

It depends. If neither you nor your spouse is covered by a workplace retirement plan, the full contribution is deductible at any income. If you (or a spouse) are covered, the deduction phases out over income ranges that adjust each year — above the top of the range you can still contribute, just without the deduction. This calculator assumes you qualify for the full deduction; check the current IRS thresholds for your filing status.

Traditional or Roth IRA — which is better?

It comes down to when you'd rather pay the tax. Traditional deducts now and taxes withdrawals as ordinary income; Roth is funded with after-tax dollars but withdrawals — contributions and growth — are tax-free after 59½. The rule of thumb: if you expect a lower tax rate in retirement than today, traditional tends to win; if higher, Roth does. Many savers split the two to hedge.

When do I have to pay tax and take withdrawals?

Every dollar you withdraw is taxed as ordinary income, and withdrawals before age 59½ generally add a 10% penalty (with exceptions). Traditional IRAs also carry required minimum distributions (RMDs) starting at age 73 — the IRS makes you draw the account down on a schedule, unlike a Roth IRA, which has no lifetime RMDs.

Can I have a traditional IRA and a 401(k)?

Yes — the contribution limits are separate, so you can max both. But being covered by a 401(k) can reduce or eliminate your traditional IRA deduction above certain income levels. If your deduction is phased out, a Roth IRA (or the 'backdoor Roth' for high earners) is often the better home for those dollars.
