A Roth IRA calculator projects what your after-tax contributions can grow to, tax-free. For 2026 you can put in up to $7,500 ($8,600 if you are 50 or older), as long as your modified AGI is under $153,000 single or $242,000 married filing jointly. Example: $7,500 a year for 30 years at 6% grows to about $628,513, all of it tax-free after 59½.

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

The 2026 IRA limit is $7,500, up from $7,000 in 2025. If you are 50 or older by December 31, 2026 you can add a $1,100 catch-up, for $8,600. The limit is shared across all your IRAs, traditional and Roth together, and you can’t contribute more than your taxable compensation for the year. Contributions for 2026 can be made until the April 15, 2027 filing deadline.

What happens if my income is inside the phase-out range?

Your limit shrinks in proportion to how far into the range you are, rounded up to the next $10, with a $200 minimum (IRS Publication 590-A, Worksheet 2-2). The calculator does this automatically.

Worked example. Single, age 40, MAGI $160,500. That is $7,500 into a $15,000-wide range, or 50%.

$7,500 × 50% = $3,750 reduction. $7,500 − $3,750 = $3,750 allowed for 2026.

How much will my Roth IRA be worth at retirement?

It depends on three things you control (how early you start, how much you put in, how long you leave it) and one you don’t (the return). Here is $7,500 a year, contributed at the start of each year, at three assumed returns:

Years contributingAt 4%At 6%At 8%
10 years ($75,000 in)$93,648$104,787$117,341
20 years ($150,000 in)$232,269$292,445$370,672
30 years ($225,000 in)$437,463$628,513$917,594
40 years ($300,000 in)$741,199$1,230,358$2,098,358

These are arithmetic, not forecasts. Real returns vary year to year, and a bad decade near the end matters more than a bad decade at the start.

When can I take money out of a Roth IRA?

Roth IRA or traditional IRA: which is better?

A traditional IRA may give you a deduction now and taxes you later; a Roth gives no deduction now and no tax later. If your tax rate in retirement will be higher than today, the Roth usually wins; if lower, the traditional usually wins. Tax-free Roth withdrawals also don’t count toward the income that makes Social Security taxable or that sets Medicare IRMAA surcharges, which matters more than most people expect.

What if I earn too much for a Roth IRA?

You can still get money into a Roth by converting. There is no income limit on conversions. A conversion is taxed as income in the year you do it. The Roth conversion calculator shows what a conversion costs and when it pays back; the Roth conversion checklist covers the traps.

At an assumed 6% a year, contributed at the start of each year: about $104,800 after 10 years, $292,500 after 20 years and $628,500 after 30 years. At 8% the 30-year figure is about $917,600. Returns are not guaranteed.

Is a Roth IRA calculator the same as a Roth conversion calculator?

No. This calculator projects new yearly contributions. A Roth conversion calculator estimates the tax cost of moving money you already have in a traditional IRA or 401(k) into a Roth.

What is the Roth IRA five-year rule?

Earnings are tax-free only once you are 59 and a half and at least five tax years have passed since your first Roth IRA contribution. Your contributions themselves can be withdrawn at any time without tax or penalty.
