roth ira calculator

Roth IRA calculators are online tools that estimate how much your Roth IRA could grow over time and whether you’re eligible to contribute (and how much).

What a Roth IRA calculator does

• Estimates your future balance at retirement based on your age, contributions, and an assumed rate of return.

• Shows how a Roth IRA compares with a regular taxable account by modeling taxes on investment gains.

• Checks current contribution limits and whether your income is too high for full or any Roth IRA contributions.

Key inputs you’ll usually enter

• Current age, planned retirement age, and starting Roth IRA balance.

• Annual contribution amount and whether you’re eligible for the age‑50+ catch‑up contribution.

• Filing status and income (to see if you qualify, and if your contribution must be reduced).

• Assumed annual investment return, often defaulting around 6% but adjustable.

Current contribution limits snapshot (2025–2026)

• For 2025, Roth IRA contributions are generally capped at 7,000 dollars, or 8,000 dollars if you are 50 or older.

• For 2026, the cap increases to 7,500 dollars, or 8,600 dollars with the age‑50+ catch‑up.

• Above specific income ranges (which vary by filing status), the allowed contribution is phased down to zero.

Example comparisons calculators can show

• One calculator example shows a Roth IRA reaching a larger tax‑free balance by age 65 than a comparable taxable account because no tax is due on qualified withdrawals.

• Another example shows that, for certain assumptions, a pre‑tax IRA might end with a higher after‑tax balance than a Roth, illustrating that the “better” option depends on tax brackets and assumptions.

Where to try a Roth IRA calculator

• Consumer finance sites like NerdWallet and Bankrate host free Roth IRA calculators that incorporate current year limits and income phase‑outs.

• General investing calculator sites offer Roth IRA vs taxable account tools if you want to compare tax‑advantaged and regular investing side by side.

TL;DR: Use a Roth IRA calculator by plugging in your age, income, and contributions to see projected tax‑free retirement savings and to confirm how much you’re allowed to contribute under current IRS rules.
