This Roth IRA calculator projects how after-tax Roth IRA contributions grow into tax-free wealth through compound interest. Enter your current age, retirement age, annual contribution, and expected return rate to build your wealth projection in real time. The Roth IRA savings snapshot displays your total balance, contributions, tax-free earnings, and estimated tax savings versus a taxable account.
Compound interest accelerates Roth IRA growth exponentially — 83% of the 35-year balance comes from tax-free earnings, not contributions.
A Roth IRA is an individual retirement account that allows your savings to grow completely tax-free. Unlike traditional retirement accounts where contributions are tax-deductible upfront, a Roth IRA uses after-tax dollars — meaning every dollar of capital gains, dividends, and compound interest you accumulate can be withdrawn 100% tax-free in retirement.
All dividends, capital gains, and investment returns compound over decades without any annual tax drag.
You can withdraw your original contributions at any time for any reason with zero taxes or penalties.
Unlike Traditional IRAs, Roth IRAs have no Required Minimum Distributions (RMDs) during your lifetime.
Pass tax-free assets to your beneficiaries, allowing your compound wealth to benefit future generations.

Answers to the 9 most common Roth IRA questions about Roth IRA contribution limits, Roth IRA withdrawal rules, compound interest, Roth IRA income limits, and retirement planning. Each answer references current IRS rules, Roth IRA distribution details, and specific dollar amounts so you can make informed decisions about your Roth IRA strategy.
A Roth Individual Retirement Account (IRA) is an after-tax retirement account offering 100% tax-free growth and tax-free withdrawals in retirement. You contribute post-tax income, and earnings compound without taxes. At age 59½ with a 5-year-old account, all distributions are tax-free. Roth IRAs have no Required Minimum Distributions (RMDs).
For 2025, you can contribute up to $7,000 annually if under age 50, or $8,000 if age 50 or older ($1,000 catch-up contribution). For 2026, the limit rises to $7,500 ($8,600 for age 50+). Single filers with MAGI over $165,000 and married joint filers over $246,000 cannot make direct contributions in 2025.
You can withdraw original contributions anytime without taxes or penalties. Earnings qualify for tax-free withdrawal once you reach age 59½ and the account meets the Five-Year Rule. Early earnings withdrawals avoid penalties for first-time home purchases (up to $10,000), qualified disability, or higher education expenses.
Yes, compound interest drives exponential Roth IRA growth over time. A $7,000 annual contribution at an 8% return grows to $115,396 in 10 years, $392,570 in 20 years, and $1,450,568 in 35 years. Tax-free status prevents tax drag, allowing 100% of your earnings to compound.
Increasing your monthly contribution raises your principal and compounds into significantly higher retirement savings. Adding $100 per month ($1,200 per year) at an 8% return produces approximately $146,000 in additional tax-free wealth over 30 years.
Your return rate determines investment growth speed. Over 30 years with a $7,000 annual deposit, a 6% return yields $586,000; an 8% return yields $849,703; and a 10% return yields $1,266,000. Adjust your return rate in the calculator to model conservative, moderate, or aggressive growth.
Your Roth IRA remains unchanged because it is an individual account held at a brokerage (such as Vanguard, Fidelity, or Charles Schwab), not tied to an employer. You can also roll over a previous employer's Roth 401(k) directly into your Roth IRA without tax penalties.
No, qualified Roth IRA withdrawals in retirement are 100% tax-free. After reaching age 59½ and meeting the Five-Year Rule, you pay zero income tax on distributions. Roth IRAs also have no Required Minimum Distributions (RMDs) during your lifetime.
Yes, you can contribute to both accounts simultaneously. In 2025, you can contribute up to $7,000 to a Roth IRA ($8,000 if 50+) and up to $23,500 to a 401(k) ($31,000 if 50+). This combination provides current-year tax deductions via the 401(k) alongside tax-free retirement growth in the Roth IRA.
