🌱Roth IRA Calculator

About this tool

Enter your modified adjusted gross income, filing status and age, your current Roth balance, planned yearly contribution, retirement age, expected return and the tax drag a regular account would suffer. You'll see your allowed 2026 contribution, the projected tax-free balance and how much more it's worth than the same investments in a taxable account.

How Roth IRAs work

Roth IRA contributions are made with money you've already paid tax on. In return, investment growth is tax-free and qualified withdrawals in retirement (after age 59½, once the account is five years old) are completely tax-free. For 2026 the limit is $7,500, or $8,600 from age 50, but you can't contribute more than your earned income. The amount you're allowed phases out between $153,000 and $168,000 of modified AGI for single and head-of-household filers, and between $242,000 and $252,000 for married couples filing jointly. In between, it's reduced proportionally and rounded up to the next $10. For example, a single filer with $160,000 of MAGI can contribute $4,000. Above the range, many people make a non-deductible traditional IRA contribution and convert it, the so-called backdoor Roth, though the pro-rata rule applies if they hold other pre-tax IRAs. Contributing $7,500 a year for 30 years at 7% grows to about $758,000, all of it tax-free. Roths suit people who expect the same or a higher tax rate in retirement, and there are no required minimum distributions for the original owner. Your contributions, but not earnings, can be withdrawn at any time. Honest limits: returns aren't guaranteed, the limits and phase-outs change yearly, and the five-year and conversion rules have nuances. This isn't financial or tax advice. The 401(k) calculator, the HSA calculator and the compound interest calculator are related.
