Enter your assumptions, compare Roth growth with a taxable account, and review the annual schedule to see how tax-free growth can affect long-term retirement savings.
Enter your current balance, current age, and retirement age so the calculator can estimate how many years your money has to compound.
Turn on the max contribution option to use the annual IRA limit, or switch it off to test a custom yearly contribution.
Your expected rate of return drives compound interest, and your marginal tax rate estimates the annual tax drag inside a taxable account.
Read the summary, compare the graph lines, and use the annual schedule to see when the Roth IRA starts pulling ahead.
This Roth IRA calculator with taxable comparison is most useful when you are evaluating long holding periods. A Roth IRA does not lower your taxes today, but qualified withdrawals are tax-free later. A taxable brokerage account has fewer contribution restrictions, yet annual taxes on growth can slow compounding over time. That is the tradeoff the calculator is built to show.
You do not need perfect assumptions to get value from the result. Run more than one scenario. Test a conservative return, a moderate return, and an aggressive return. Then compare maxing out the contribution limit with a smaller annual contribution. This helps you understand how savings rate, time horizon, and tax-free growth work together.
The result table, graph, and annual schedule each answer a different planning question. Use all three together before you make contribution decisions.
This is your projected account value at retirement. In the Roth IRA column, the model assumes qualified withdrawals are tax-free. In the taxable account column, annual growth is reduced by the tax rate you entered.
Principal means the money you put in, including your starting balance and every annual contribution. This helps you see how much of the final balance came from saving and how much came from investment growth.
Total interest captures compound growth. Total tax estimates the yearly tax drag inside the taxable account. The bigger the gap between those columns, the more valuable tax-free growth may be for your plan.
The graph shows how principal, Roth IRA balance, and taxable balance change over time. In the early years, the lines may stay close together. Later, the Roth line often separates because gains keep compounding without annual tax friction. That is the clearest visual sign that a Roth IRA vs taxable account calculator can offer.
The annual schedule is useful when you want to audit the math. If you plan to retire early, increase contributions after a raise, or switch to a more conservative return assumption, the schedule helps you see exactly when those changes start affecting your projected retirement balance.
The calculator uses a simple annual compounding model for the Roth IRA and a tax-adjusted compounding model for the taxable account.
The basic Roth IRA formula is ending balance equals starting balance plus growth plus annual contribution. If the account starts with $50,000 and earns 6%, growth is $3,000. Add a $7,500 contribution and the year-end balance becomes $60,500.
The next year starts from the new, higher balance. That means your gains can begin generating more gains. Over a long timeline, compound interest often matters more than any single annual contribution.
Using this calculator's sample values of age 30, $30,000 starting balance, $7,500 annual contribution, 6% return, and age 65 retirement, the Roth IRA grows to about $1,066,343. That same contribution pattern in a taxable account ends lower because taxes reduce annual reinvestment.
Roth IRAs include strict annual contribution limits set by the IRS. For 2025, individuals under age 50 may contribute up to $7,000, while those age 50 and older qualify for an additional $1,000 catch-up contribution, bringing their annual limit to $8,000. However, eligibility is subject to income-based phase-out ranges depending on filing status. High-income earners may see reduced contribution allowances or lose the ability to contribute directly altogether. Understanding these limits is essential for maximizing long-term growth, preventing excess contributions, and ensuring compliance with IRS rules. Savers who exceed income limits may still access Roth benefits through a “backdoor Roth IRA†strategy if permitted.
Roth IRA withdrawal guidelines are designed to provide flexibility while protecting the account’s long-term value. Contributions can always be withdrawn tax-free, but earnings follow specific qualification rules. Earnings become tax- and penalty-free only after age 59½ and after satisfying the five-year rule, which begins on January 1 of the year of your first Roth IRA contribution. Early withdrawals of earnings may trigger income tax and a 10% penalty unless an exception applies. Common exceptions include qualified education expenses, certain medical costs, disability, or up to $10,000 toward a first-time home purchase. Understanding these withdrawal details helps you avoid unnecessary penalties while strategically planning how and when to access your tax-free retirement funds.
Scenario planning helps you see whether a Roth IRA should be your first savings priority or one part of a broader retirement plan.
If you are 25 with $5,000 saved and you contribute $4,000 per year at 7%, time does most of the work. Starting early gives your tax-free growth more years to compound.
If you are 42 with $80,000 saved, test how much your final balance changes when you raise annual contributions from $4,000 to $7,500. Small yearly increases can still have a big effect.
Once you reach age 50, the catch-up contribution raises your IRA limit. In 2026, that means up to $8,600. Use the calculator to see how those larger deposits may close a retirement savings gap.
Many savers max out the Roth IRA first and then send extra money to a taxable brokerage account. That order often makes sense because Roth contribution room is limited and does not carry over.
California and New York investors may see a larger benefit from tax-free growth because annual state taxes can add more drag to a taxable account. Florida and Texas residents may see a smaller state-level difference.
Try a lower expected return if you are close to retirement or want a more cautious forecast. A conservative assumption can give you a safer target for retirement income planning.
The biggest gap in many Roth IRA calculator pages is eligibility guidance. Your filing status and modified adjusted gross income can reduce or eliminate your ability to contribute directly.
A Roth IRA calculator can project strong long-term tax-free growth, but you still need to qualify to contribute. The IRS looks at earned income and modified adjusted gross income, often called MAGI. If your income falls inside the phaseout range for your filing status, your allowed contribution is reduced. If it is above the upper limit, a direct Roth IRA contribution is not allowed for that year.
This matters if you receive bonuses, freelance income, or equity compensation, or if your filing status changes after marriage. High earners sometimes explore a backdoor Roth IRA strategy, but pre-tax IRA balances and pro-rata tax rules can complicate that move.
Single, married filing jointly, and married filing separately can each face different phaseout thresholds. Review current IRS limits before you fund the account.
A raise late in the year can change your MAGI enough to reduce your allowed contribution. Checking early can help you avoid excess contribution penalties.
If you are above the direct Roth IRA income limit, a taxable brokerage account can still support long-term investing while you review other tax-advantaged options.

Get answers to common questions about Roth IRA contributions, withdrawals, taxes, and retirement planning.
A Roth IRA is a retirement account where you contribute after-tax money and enjoy tax-free growth and tax-free withdrawals in retirement. A traditional IRA allows pre-tax contributions but requires you to pay taxes on withdrawals. The Roth IRA benefits people who expect higher taxes in the future or want more flexibility later in life.
The 5-year rule requires that at least five tax years pass from your first Roth IRA contribution before earnings can be withdrawn tax-free. The countdown starts on January 1 of the contribution year, regardless of the specific contribution date. This rule applies to conversions as well, each with its own 5-year window.
Yes. You can withdraw your original Roth IRA contributions at any time without taxes or penalties. Only the earnings portion is restricted and may be subject to penalties if withdrawn early. This makes Roth IRAs more flexible than most retirement plans.
Early withdrawals of earnings may result in both income tax and a 10% early withdrawal penalty. Exceptions exist—such as qualified education expenses, medical costs, disability, and first-time home purchases—but the 5-year rule must still be satisfied to avoid taxes.
No. Roth IRAs do not require distributions at any age, unlike traditional IRAs or employer retirement plans. This gives you full control over when and how your money is used and allows your savings to continue growing tax-free for as long as you wish.
Roth IRA contribution eligibility is based on Modified Adjusted Gross Income (MAGI). High-income earners may have reduced contribution limits or be unable to contribute directly. However, many use a “backdoor Roth IRA†strategy to legally bypass income restrictions.
For 2025, the contribution limit is $7,000 per year for individuals under age 50. Anyone age 50 or older can contribute an additional $1,000 as a catch-up, for a total of $8,000. These limits apply across all IRAs combined.
Contributions are always penalty-free. Earnings may face a 10% penalty plus income tax if withdrawn early. Exceptions include buying a first home, certain medical bills, health insurance during unemployment, qualified education expenses, disability, and more.
The average long-term return typically ranges between 6% and 10% annually, depending on market performance and your investment choices. Roth IRAs do not guarantee returns—performance depends on the underlying portfolio, such as stocks, bonds, or index funds.
Yes. Contributions to a Roth IRA are separate from those made to a 401(k), and you can save in both accounts simultaneously. Many savers choose this strategy for diversification, tax advantages, and maximizing long-term retirement growth.
