Your Roth IRA’s projected balance tells you how much your retirement account could be worth by the age you selected, based on your current savings, planned annual contributions, and expected investment growth. But the final balance is only part of the picture. It’s also important to understand how much you put into the account yourself and how much of the projected value comes from investment growth.
Projected Roth IRA Balance
This is the estimated value of your account at your planned retirement age. It combines your existing Roth IRA balance with the future contributions and investment growth modeled by the calculator.
Use this figure to assess whether your current savings plan is moving toward your retirement goal. If the projection falls short, you can test a higher annual contribution, a different retirement age, or a more conservative growth assumption to see how each change affects the result.
Keep in mind that the projection assumes a particular rate of growth. The market will not necessarily deliver that return every year, and your actual account value could be higher or lower.
Total Out-of-Pocket Contributions
This figure represents the contributions made during the period being modeled. It helps separate the money you add to the account from the investment growth shown in the final balance.
For example, someone contributing $6,000 annually for 25 years would contribute $150,000 over that period, excluding any starting balance. If the account grows beyond that amount, the difference reflects the existing balance and modeled investment growth, depending on how the calculator defines its output.
This distinction matters when assessing progress toward retirement. A larger account balance may reflect years of consistent saving as well as growth from investments, rather than investment performance alone.
Total Compound Growth
Compound growth describes how investment gains can accumulate on both your original money and earlier gains that remain invested. In a Roth IRA projection, this is the part of the future value that isn’t explained by the contributions counted in the calculator’s calculation.
The exact figure depends on the calculator’s definition of contributions and growth. If your starting balance is included in the projected account value but excluded from the contributions total, the displayed growth figure will also include that starting balance. For that reason, check the result labels and calculation carefully before interpreting this figure as investment profit alone.
Estimated Tax Savings in Retirement
A Roth IRA can offer a tax advantage because qualified withdrawals are generally free from federal income tax. However, the value of that advantage depends on the tax treatment being compared and the assumptions used.
An estimated tax-savings figure should explain what it compares—for example, the hypothetical tax on a distribution from a taxable account or a tax-deferred retirement account versus a qualified Roth IRA distribution. Different comparisons can produce very different results.
The calculator’s tax-savings estimate should therefore be treated cautiously unless its assumed tax rate and calculation method are clearly disclosed. Your actual tax outcome depends on your circumstances and the applicable rules. You can read the IRS explanation of Roth IRAs for details about contributions and distributions.
How Your Retirement Age Affects Roth IRA Growth
The time between today and retirement can have a substantial effect on a Roth IRA projection. When investment gains remain in the account, they can contribute to further growth in later years. Starting earlier gives your money more time to grow, while continuing to contribute can add to the balance throughout that period.
Consider someone who is 30 and wants to estimate their Roth IRA balance at age 60. They can compare that projection with one ending at age 65, keeping the starting balance, annual contribution, and assumed growth rate unchanged. The second scenario allows for five additional years of modeled growth and contributions, if contributions continue throughout those years.
That comparison can help answer a practical question: how much does the plan depend on working and saving for longer? It does not mean delaying retirement is always the right decision. Health, income, other savings, and personal goals also affect when someone can afford to retire.
To understand the effect of time more clearly, change only the planned retirement age first. Then try adjusting the annual contribution separately. This makes it easier to see which change has the greater effect on the projected balance.
How Annual Contributions and Investment Returns Shape Your Roth IRA
Your projected retirement balance depends on more than the return percentage. The starting balance, the amount you contribute, and the time each contribution remains invested all influence the result.
Starting With an Existing Roth IRA Balance
If you already have a Roth IRA, enter its current balance rather than treating the account as if you were starting from zero. The money already invested has the potential to grow throughout the remaining investment period.
This is particularly relevant for people who have been contributing for several years. Their future projection includes the effect of earlier saving, not just the contributions they plan to make from now on.
If you’re opening your first Roth IRA, use a starting balance of zero or the amount you expect to transfer into the account, if the calculator permits that scenario.
How Much You Contribute Each Year
Annual contributions add new money to your retirement savings. Raising the contribution can increase the projected balance even if the assumed rate of return remains unchanged.
For a useful comparison, run the calculator with your current planned contribution and then with a higher amount. The difference helps show the potential value of saving more consistently. It also helps you distinguish money you would need to set aside from growth the calculator assumes your investments may earn.
Your contribution must still comply with the applicable IRS rules. The amount you are allowed to contribute can depend on your taxable compensation, age, income, and filing status.
Choosing an Expected Annual Growth Rate
The expected annual growth rate is an assumption about how your investments might perform over the period. It is not a rate guaranteed by a Roth IRA provider.
A Roth IRA is a type of retirement account, not a specific investment. The account might hold mutual funds, exchange-traded funds, individual stocks, bonds, or other permitted investments, depending on the provider and account arrangements. Different investment choices have different risks and potential returns.
Try several growth assumptions instead of relying on just one. A lower-return scenario can reveal whether your retirement goal remains within reach if the market performs less favorably than you hope. A higher-return scenario can help illustrate potential upside, but it should not be treated as the expected outcome without a sound basis.
Why Consistent Contributions Matter
Regular saving can help build a retirement balance because new contributions are added over time, giving each deposit an opportunity to participate in future investment performance. Contributions made earlier generally have more time to grow than those made shortly before retirement.
However, a projection based on the same contribution every year does not account for every real-life change. Your income may rise or fall, contribution limits can change, and you may need to pause saving for other priorities. Revisit the estimate when your plans change rather than treating a single result as a fixed retirement forecast.
Roth IRA Contribution Limits and Income Eligibility
The IRS limits how much you can contribute to traditional and Roth IRAs each year. These limits are important when using a retirement calculator because entering an amount above your eligible contribution limit can make the projection unrealistic.
Roth IRA Contribution Limits for 2026
For the 2026 tax year, the total amount you contribute to all your traditional and Roth IRAs generally cannot exceed the smaller of your eligible taxable compensation or the applicable annual limit:
| Age during 2026 |
Combined annual IRA contribution limit |
| Under age 50 |
$7,500 |
| Age 50 or older |
$8,600 |
These are combined limits across traditional and Roth IRAs, not separate limits for each account. Your allowable Roth IRA contribution may also be reduced by your income or limited by your eligible compensation.
The IRS publishes current figures and rules on its IRA contribution limits page. Check the rules for the specific tax year you are contributing for, because limits can change.
How Income Affects Roth IRA Contributions
Unlike simply entering an amount into a calculator, making a direct Roth IRA contribution depends on your modified adjusted gross income (MAGI) and tax filing status. Depending on your income, you may be able to contribute the full amount, a reduced amount, or nothing directly to a Roth IRA for that year.
For 2026, the income phase-out range for direct Roth IRA contributions is $153,000 to $168,000 for single filers and heads of household, and $242,000 to $252,000 for married couples filing jointly. Different rules apply to married people filing separately who lived with their spouse during the year.
These ranges are not a substitute for calculating your MAGI and checking the detailed IRS eligibility rules. You can find the current thresholds in the IRS announcement of 2026 retirement-plan limits.
Can You Have a Roth IRA and a 401(k)?
Yes. Having a 401(k) through your employer does not, by itself, prevent you from contributing to a Roth IRA. The Roth IRA’s own contribution limit, income rules, and compensation requirements still apply.
A workplace retirement plan and a Roth IRA can serve different roles in a retirement plan. Before deciding how much to contribute to each, consider employer matching contributions, investment options, fees, access to funds, and the tax treatment that fits your circumstances.
When Can You Withdraw Money From a Roth IRA Tax-Free?
One of the main attractions of a Roth IRA is the possibility of taking qualified retirement distributions without federal income tax. But not every withdrawal is automatically tax-free, so it is important to distinguish regular contributions from investment earnings.
Withdrawing Your Regular Contributions
Roth IRA distribution rules generally treat regular contributions as coming out before converted amounts and investment earnings. Because regular contributions are made with after-tax money, withdrawing those contributions is generally not subject to income tax or the early-distribution penalty.
The rules can become more complicated if your account includes conversions, rollovers, or earnings. Don’t assume that every dollar above your original contributions can be withdrawn under the same conditions.
When Investment Earnings Can Be Withdrawn Tax-Free
For a distribution to be qualified, the Roth IRA generally must satisfy a five-tax-year requirement, and the distribution must meet an eligible condition. One common condition is that the account owner is at least age 59½ when the distribution occurs. Other qualifying circumstances can include disability or distributions to a beneficiary after the owner’s death; special rules may also apply in certain cases.
The five-year period generally begins with the first tax year for which you made a contribution to a Roth IRA established for your benefit. It is not simply five years from the date you make your latest contribution.
For detailed rules and exceptions, consult IRS Publication 590-B. This is especially important if you are considering an early withdrawal, a conversion, or a distribution before retirement.
A Roth IRA Is Not the Same as a Guaranteed Investment
The phrase “tax-free growth” refers to the potential tax treatment of qualified distributions, not a promise that the account will increase in value. Investments held inside a Roth IRA can lose money, and market performance can differ significantly from the growth rate entered into a calculator.
Use the projected balance as a planning estimate. Before making a withdrawal decision, consider the account’s distribution rules, the investments it holds, and whether the money is needed for another purpose.
Why Roth IRA Growth Can Be Valuable in Retirement
A Roth IRA can be useful for retirement planning because contributions are generally made with after-tax money, and qualified distributions are generally not included in federal taxable income. This differs from a traditional IRA, where deductible contributions may reduce taxable income in the contribution year and withdrawals are generally taxable.
The best choice depends on more than the account’s projected balance. Your current tax situation, expected tax situation in retirement, eligibility, investment choices, and savings needs can all affect whether a Roth IRA fits your plan.
For example, two people with the same projected retirement balance may have different tax outcomes because they have different account types, contribution histories, or withdrawal circumstances. A calculator that projects the Roth IRA balance alone cannot determine which account is best for a particular person.
It’s also important to separate tax advantages from investment risk. The account structure can affect how distributions are taxed, but it does not remove market risk or guarantee that your investments will grow.
Assumptions Behind Your Roth IRA Projection
A retirement projection is most useful when you understand what it includes and what it leaves out. CalculatorSee estimates a future Roth IRA balance using the values entered for age, retirement age, current balance, annual contributions, and expected growth rate. It should not be interpreted as a promise of a particular outcome.
A steady assumed return: The calculation uses the growth rate you enter. Real markets do not deliver the same return every year, and losses early or late in a retirement-saving period can affect the actual outcome.
Annual contribution timing: The formula’s result depends on when contributions are assumed to occur. Deposits made at the beginning of each year have more time to grow than deposits made at the end. The worked example should match the timing used in the calculator’s code.
Contribution eligibility: The projection does not automatically establish that you qualify to contribute the entered amount. Check the current annual limit, your taxable compensation, and the income rules that apply to your tax filing status.
Inflation and purchasing power: Unless an inflation adjustment is explicitly included, the projected balance is stated in future dollars. Its purchasing power may be lower than the same dollar amount today.
Taxes and estimated savings: Qualified Roth IRA distributions can be tax-free, but the calculator’s estimated tax savings depend on how that output is defined. If the calculation assumes a tax rate or compares Roth IRA withdrawals with another account type, those assumptions should be disclosed clearly. The result should not be treated as a personal tax estimate without that information.
Investment costs and performance: Fees, investment selection, and market conditions can affect the actual account balance. Unless the calculator includes those factors explicitly, its projection should not be assumed to model them individually.
Use the calculator to compare possible saving paths, then revisit the result when your contribution plan, retirement age, or assumptions change.
