Roth IRA Calculator: Estimate Your Tax-Free Retirement Growth
A Roth IRA is one of the most powerful retirement savings tools available to American taxpayers. Unlike a Traditional IRA, contributions to a Roth IRA are made with after-tax dollars, meaning you pay taxes now but your money grows completely tax-free. When you withdraw funds in retirement, you owe nothing to the IRS — not on your contributions and not on decades of accumulated growth. For many savers, this tax-free compounding can result in tens or even hundreds of thousands of dollars in savings over a lifetime.
Tax-free growth is especially valuable for younger savers and those who expect to be in a higher tax bracket during retirement. Because you have already paid taxes on your contributions, every dollar your investments earn belongs entirely to you. There are no required minimum distributions during your lifetime, which means your money can continue growing for as long as you want. This flexibility makes the Roth IRA an excellent tool for both retirement income and legacy planning.
Roth IRAs are best suited for individuals who currently fall below certain income thresholds set by the IRS. For 2024, single filers with a modified adjusted gross income below $161,000 and married couples filing jointly with income below $240,000 are eligible to contribute. Contribution limits are $7,000 per year for those under 50 and $8,000 for those 50 and older. If your income exceeds the phase-out range, you may still be able to contribute through a "backdoor" Roth conversion strategy — a topic worth discussing with a qualified financial planner.
Use the calculator below to estimate how much your Roth IRA could be worth by the time you retire. Enter your current age, income, filing status, annual contribution, expected rate of return, and target retirement age. The calculator applies IRS contribution limits and income phase-outs automatically, then projects your balance using compound annual growth. You will also see an estimate of how much you could save in future taxes compared to holding the same investments in a taxable account.

Understanding Roth IRA Retirement Savings
A Roth IRA (Individual Retirement Account) is a tax-advantaged savings account that allows your investments to grow completely tax-free. Unlike Traditional IRAs, Roth contributions are made with after-tax dollars, meaning you will not owe any federal income tax when you withdraw your money in retirement. This makes the Roth IRA one of the most effective long-term wealth-building tools available to American taxpayers.
The power of a Roth IRA lies in compound growth over time. When your investments earn returns year after year, those returns generate their own returns, creating exponential growth. Because Roth withdrawals are tax-free, you keep every dollar of that compounded growth — unlike taxable brokerage accounts where capital gains taxes erode your returns.
Roth IRAs are especially beneficial for younger workers who expect their income and tax rates to rise over time. By paying taxes on contributions now at a lower rate, you avoid paying higher rates on potentially much larger withdrawals in retirement. Additionally, Roth IRAs have no required minimum distributions during the account holder's lifetime, providing unmatched flexibility in retirement planning.
Eligibility to contribute directly to a Roth IRA depends on your modified adjusted gross income and filing status. For 2024, single filers can contribute up to $7,000 ($8,000 if age 50 or older) as long as their income is below $161,000. Married couples filing jointly have a phase-out range beginning at $230,000. Those above the income limits may explore backdoor Roth conversion strategies with the help of a financial professional.
Frequently Asked Questions
What is the difference between a Roth IRA and a Traditional IRA?
The primary difference is when you pay taxes. With a Traditional IRA, contributions may be tax-deductible now, but withdrawals in retirement are taxed as ordinary income. With a Roth IRA, you contribute after-tax dollars, but all qualified withdrawals — including decades of investment growth — are completely tax-free.
How much can I contribute to a Roth IRA in 2024?
For 2024, the annual contribution limit is $7,000 if you are under age 50, and $8,000 if you are 50 or older. These limits apply across all your IRAs combined, not per account. Your eligible contribution may be reduced if your income exceeds certain thresholds.
What happens if my income is too high for a Roth IRA?
If your modified adjusted gross income exceeds the Roth IRA income limits, you may still be able to contribute through a backdoor Roth conversion. This involves making a non-deductible Traditional IRA contribution and then converting it to a Roth. Consult a tax professional to determine if this strategy is appropriate for your situation.
When can I withdraw money from a Roth IRA?
You can withdraw your original contributions at any time without taxes or penalties. To withdraw earnings tax-free, you generally must be at least 59½ and the account must have been open for at least five years. There are exceptions for first-time home purchases and other qualifying events.
