An IRA calculator estimates the future value of a Traditional or Roth IRA. Your current balance, yearly contribution, expected return, and years to retirement drive the result. It shows which account type may fit you best. In addition, it shows how steady contributions build wealth over time.
Retirement savings rarely feel urgent at first. However, the totals become clear when you see them in numbers. An Individual Retirement Account, or IRA, is a popular way to save outside a 401(k). In addition, an IRA calculator helps you check if your savings are on track.
An IRA is not tied to your employer. Therefore, freelancers and self-employed workers can use it too. It also works as a second account beside a workplace plan. Gains compound year after year inside the account. For example, you avoid yearly tax drag on dividends and interest. As a result, the gap grows large over several decades. An IRA calculator makes that gap visible in dollars.

Also, use the IRA calculator above for a quick estimate. Then read the guide below for the rules behind it.
What Is an IRA?
An IRA is a tax-advantaged investment account. Also, any person with earned income can open one. Your job does not matter for eligibility. You can also choose the investments inside it. For example, you can pick index funds or ETFs. Bonds and target-date funds are also common. The IRS sets yearly limits on contributions.
Two main types exist for individuals. They are the Traditional IRA and the Roth IRA. Both also share the same contribution limits. However, they treat taxes very differently. This difference is the first key step. It affects what your balance is worth after tax. An IRA calculator lets you project either type’s balance with the same inputs.
Traditional IRA vs. Roth IRA: A Detailed Comparison
With a Traditional IRA, you may deduct contributions today. For example, this step can lower your current tax bill. Next, the money grows tax-deferred inside the account. Later, you pay ordinary income tax on withdrawals. A Roth IRA works in reverse. You also pay tax on contributions now. In addition, you get no deduction today. Qualified withdrawals in retirement are tax-free. This rule includes all investment growth.
| Feature | Traditional IRA | Roth IRA |
|---|---|---|
| Contribution tax treatment | Often deductible today | After-tax, no deduction |
| Withdrawal tax treatment | Taxed as ordinary income | Tax-free if qualified |
| 2026 contribution limit | $7,500 ($8,600 if 50+) | $7,500 ($8,600 if 50+) |
| Income limits to contribute | None | Phases out at higher incomes |
| Early withdrawal penalty | 10% before age 59½, with exceptions | Contributions withdrawable anytime; earnings face the 10% penalty before 59½ unless qualified |
| Required Minimum Distributions | Begin at age 73 | None during the owner’s lifetime |
How to Choose Between Them
Which one should you pick? First, compare your tax rate today with your future rate. If your future rate will be lower, Traditional often wins. You also deduct at a high rate now. Then you pay tax at a lower rate later. If your future rate will be higher, Roth often wins. Therefore, you lock in today’s lower rate now. As a result, you never pay tax on growth. If both rates look similar, the result is close. Finally, either choice can work well in that case. An IRA calculator can project the balance for either choice once you enter the same contribution and return.
Special Rules Worth Knowing
Roth earnings have a special qualified rule. First, you must be at least 59½ to qualify. In addition, the account must be open five years. This rule is called the five-year rule. Roth contributions are different from earnings. Also, you can withdraw contributions at any time. In addition, no tax or penalty applies to them. Therefore, a Roth IRA is flexible in an emergency. However, Traditional owners face a different rule. They must start required minimum distributions at age 73. Roth owners never face RMDs in their lifetime.
How an IRA Calculator Works
An IRA calculator uses five main inputs. They are current age, current balance, annual contribution, retirement age, and return. It projects your IRA value at retirement. The math is based on compound interest. Each year, your balance also grows at the assumed rate. In addition, new contributions are added on top. Therefore, an early dollar compounds much longer. A dollar in year one beats a dollar in year twenty.
Inputs to Gather First
To use one well, gather these inputs first:
- Current IRA balance: what you have saved today, from your latest brokerage statement.
- Annual contribution: how much you plan to add each year, capped at the IRS limit or your earned income, whichever is lower.
- Expected rate of return: a realistic long-term average, such as 7% for a diversified stock-heavy portfolio. Past returns never guarantee future results.
- Current age and retirement age: these set the number of compounding years, the single biggest driver of the final number.
- Tax rates now and in retirement: used to compare the after-tax outcome of Traditional versus Roth contributions.
Most tools compare Traditional and Roth side by side. This IRA calculator focuses on the projection itself: enter your inputs and it projects the balance. This step matters because after-tax results can differ a lot. It can change which account leaves more spendable cash. Treat every projection as an estimate, not a promise. Also, run a few scenarios with different inputs. For example, try different contribution amounts and returns. For a taxable account comparison, try our investment calculator. The comparison is where real insight lives.
2026 IRA Contribution Limits
For 2026, the standard IRA limit is $7,500. In addition, this limit covers Traditional and Roth accounts combined. For example, savers age 50 or older can add a catch-up. The catch-up rose to $1,100 for 2026. As a result, their total limit is $8,600. Also, the catch-up is now indexed to inflation. This change comes from the SECURE 2.0 Act. It explains the rise from $1,000 in prior years. Before you contribute, an IRA calculator can project what the $7,500 limit grows to over your timeline.
Three Rules That Shape the Limits
First, the limit is shared across accounts. For example, a $7,500 Roth contribution leaves no room for Traditional. The reverse is also true. However, opening both types does not give two limits. Second, you cannot exceed your taxable compensation. For example, someone who earned $4,000 can contribute at most $4,000. Third, married couples filing jointly have an extra option. In addition, they can fund a spousal IRA for a partner. This rule applies even with little or no earnings. Their combined pay must cover both contributions. As a result, one-earner households can contribute up to $15,000 for 2026. An IRA calculator uses your annual contribution, so stay within the shared limit when you enter it.
The Contribution Deadline
Also, contributions can be made until the tax filing deadline. For 2026, that means April 15, 2027. This rule gives you extra months to top up. You can act after you see your final income.
Roth IRA Income Limits for 2026
Anyone with earned income can fund a Traditional IRA. Roth eligibility is different, however. It depends on Modified Adjusted Gross Income, or MAGI. As a result, your allowed amount shrinks inside the phase-out range. Finally, above the top range, direct Roth contributions stop. You cannot contribute directly at all in that case.
For 2026, the phase-out ranges are:
- Single or head of household: phase-out begins at $153,000 and ends at $168,000. Above $168,000, no direct Roth contribution is allowed.
- Married filing jointly: phase-out runs from $242,000 to $252,000.
- Married filing separately (if you lived with your spouse at any point during the year): a narrow $0 to $10,000 range that is not adjusted for inflation.
Reduced Contributions and the Backdoor Roth
Also, if your income is inside the range, you can still contribute less. The IRS gives a worksheet in Publication 590-A. It helps you calculate the exact amount. High earners who are phased out often use another path. It is called the backdoor Roth strategy. First, you make a non-deductible Traditional contribution. Then you convert it to a Roth. In addition, it is legal and widely used. However, the tax mechanics are tricky. Therefore, review it with a tax professional first. After the conversion, an IRA calculator can project the Roth balance’s tax-free growth.
Traditional IRA Deduction Limits for 2026
There is no income cap on Traditional contributions. However, a deduction limit still applies. If neither spouse has a workplace plan, you can deduct in full. Income does not matter in that case. If you or your spouse has a workplace plan, the rule changes. The deduction phases out within IRS income bands. Above the top band, you can still contribute. You just cannot deduct it. Finally, check the current IRS figures each year. These bands move with inflation. An IRA calculator projects the balance either way; the deduction only changes the tax treatment.
Compound Growth Examples With Specific Numbers
This section shows why an IRA calculator helps. The examples assume a steady 7% annual return. Contributions are made once per year. However, real markets will not deliver smooth 7% returns. However, the long-run math is still useful. It shows why starting early matters most.
Example 1: $7,500 a year for 30 years
Contribute $7,500 every year for 30 years at 7%. In addition, your total contributions are $225,000. The projected balance is about $708,000. For example, roughly $483,000 of that is investment growth. That is about 68% of the total. Compounding does most of the heavy lifting. An IRA calculator gives the same $708,000 result with these inputs.
Example 2: Starting 10 years earlier
Compare starting at age 25 versus age 35. Both retire at 65 with $7,500 a year at 7%. Also, the early starter invests for 40 years. That starter reaches about $1,497,000. In contrast, the late starter invests for 30 years. That starter reaches about $708,000. The head start costs $75,000 more in contributions. However, it adds roughly $789,000 to the balance. Time in the market beats timing the market. An IRA calculator shows the same gap when you change only the years input.
Example 3: Monthly versus annual contributions
Contribute $625 every month instead of $7,500 yearly. Over 30 years at 7%, it grows to about $762,000. That is roughly $54,000 more than the yearly schedule. For example, money paid earlier starts compounding sooner. Therefore, monthly automation is an easy upgrade. It works well if your budget allows it. An IRA calculator models the yearly schedule; the monthly schedule adds roughly $54,000 on top.
Example 4: How the return assumption changes everything
Keep $7,500 a year and a 30-year timeline. Now vary the return assumption. For example, at 6%, the balance lands near $593,000. In addition, at 8%, it reaches about $850,000. A two-point difference changes the outcome by over $250,000. Therefore, model a conservative scenario too. Do not trust a single number alone. An IRA calculator makes the return assumption easy to test: change one input and watch the balance move.
Example 5: Catch-up contributions from age 50 to 65
Contribute $8,600 every year for 15 years at 7%. This amount is for savers age 50 or older. In addition, total contributions are $129,000. The projected balance is about $216,000. Late starters have less time for compounding. As a result, every extra dollar counts more. An IRA calculator with $8,600 a year for 15 years gives the same $216,000 projection.
Worked Example: Growing $7,500 a Year
The table below sums up what an IRA calculator projects for $7,500 a year at 7%. However, actual returns are not guaranteed. They will vary from year to year.
| Years Invested | Total Contributions | Estimated Balance* |
|---|---|---|
| 10 years | $75,000 | ~$104,000 |
| 20 years | $150,000 | ~$307,000 |
| 30 years | $225,000 | ~$708,000 |
| 40 years | $300,000 | ~$1,497,000 |
Catch-Up Contributions After Age 50
Savers age 50 or older have less time to compound. Therefore, the IRS lets them contribute more. For 2026, the catch-up is $1,100. Their total limit is $8,600. Also, this amount is now indexed to inflation. As a result, it should rise slowly over time. It will not stay frozen. An IRA calculator lets you test the catch-up amount against the standard amount.
If you are in your 50s and behind, use this lever. Also, it needs no new account or special paperwork. You simply contribute more before April. In addition, pair it with a 401(k) catch-up if you have one. Workplace limits are separate and much higher.
SEP and SIMPLE IRAs: Beyond the Personal Account
Not every IRA is opened by an individual saver. A SEP IRA is set up by an employer. Also, self-employed people can use it too. For 2026, it allows up to 25% of pay or $72,000. The lower amount applies. This cap is far above the personal limit. A SIMPLE IRA suits small businesses. It works somewhat like a mini 401(k). For 2026, staff can contribute up to $17,000. In addition, savers age 50 or older can contribute $21,000. Required employer contributions apply on top.
Like a personal Traditional IRA, both grow tax-deferred. Also, they are taxed on withdrawal. However, their rules and mechanics differ. Therefore, compare all three options first. This step matters most for self-employed workers.
Common Mistakes to Avoid
Small errors can throw projections off by a lot. In fact, they can cost hundreds of thousands of dollars. Watch for these eight mistakes when you use an IRA calculator.
Mistake 1: Assuming an unrealistically high rate of return
For example, projecting 10% or 12% returns for decades looks easy. However, long-run stock returns average closer to 7% after inflation. In addition, a conservative mix earns even less. Therefore, model your plan at 6% or 7%. An average market should still reach your goal. An IRA calculator is only as honest as the return you enter.
Mistake 2: Ignoring Roth income phase-outs
Contributing in full above the MAGI limit creates an excess. As a result, the IRS penalizes it at 6% per year until removed. Check your income before you contribute. Do not check it after.
Mistake 3: Forgetting the limit is shared across accounts
The $7,500 cap covers all your IRAs combined. It is not per account. However, splitting money across brokerages does not double it. The IRS gets Form 5498 from each custodian. As a result, over-contributions are easy to detect.
Mistake 4: Missing the contribution deadline
You have until April 15 of the next year. In fact, that date is the tax filing deadline. Missing it loses that year’s space for good. Unused room does not carry forward.
Mistake 5: Comparing balances without accounting for taxes
A $700,000 Traditional IRA is not equal to a $700,000 Roth IRA. The Traditional balance will shrink at withdrawal. Also, tax applies as ordinary income. The Roth balance is yours in full. Always compare after-tax values first. An IRA calculator projects the pre-tax balance; compare after-tax values yourself.
Mistake 6: Withdrawing early and triggering penalties
Withdrawing before age 59½ usually triggers a 10% penalty. In addition, ordinary income tax applies on top. Only narrow exceptions exist. Raiding savings early is very costly.
Mistake 7: Never updating the plan after life changes
A raise or job change can change your eligibility. Also, marriage or a new filing status can too. These events can change deduction limits. Review your numbers once a year and re-run the IRA calculator so your plan can adapt in time.
Mistake 8: Skipping catch-up contributions after 50
Many savers over 50 keep the standard amount out of habit. As a result, they leave $1,100 of space unused each year. Over 15 years at 7%, that money could grow to roughly $28,000. Do not leave it unused. An IRA calculator shows what that $1,100 a year becomes over 15 years.
Frequently Asked Questions
How many Roth IRAs can you have?
There is no limit on the number of Roth accounts. The $7,500 limit applies to all of them combined. The limit is $8,600 if you are 50 or older. In addition, multiple accounts are for organization only. They do not let you contribute more.
Can I contribute to both a Traditional and a Roth IRA in the same year?
Yes, you can split contributions in the same year. However, the total cannot exceed the yearly limit. For example, you could put $4,000 in Traditional. Then you could put $3,500 in Roth. You cannot put $7,500 in each.
What happens if I contribute more than the IRA limit?
Excess contributions face a 6% excise tax each year. In addition, the tax lasts while the excess stays in place. You can usually fix it by withdrawing the excess. Include any earnings on it too. Act before you file that year’s return.
How accurate are IRA calculator projections?
Any projection is an estimate, never a guarantee. Actual returns vary from year to year. For example, calculators assume smooth average growth. Use an IRA calculator as a directional guide. They help you compare strategies, not predict exact balances.
Should I choose a Traditional or Roth IRA?
Compare your tax rate today with your future rate. If your future rate is lower, Traditional usually wins. For example, its upfront deduction helps you now. If your future rate is higher, Roth usually wins. In addition, its tax-free withdrawals help you later. When rates look similar, either choice is reasonable. Many savers split between both for diversification. An IRA calculator can project the balance for either choice with the same inputs.
Can I contribute to an IRA if I already have a 401(k)?
Yes, a workplace plan does not block an IRA. In addition, IRA limits are separate from 401(k) limits. However, a workplace plan can affect deductions. The deduction phases out at certain income levels. This rule applies when you or your spouse is covered.
When can I withdraw from an IRA without penalty?
Traditional withdrawals are penalty-free from age 59½. However, you still owe ordinary income tax. Roth contributions can be withdrawn at any time. In addition, no tax or penalty applies to them. Roth earnings need two conditions for tax-free withdrawal. Also, you must be 59½ and the account must be five years old. Traditional RMDs begin at age 73.
Put Your Numbers to Work
Tables give a useful starting point. Also, your amount, timeline, and return are unique to you. Small, consistent contributions started today usually win. For example, they beat larger contributions started years later. Therefore, run your numbers right now in the IRA calculator above. For money outside an IRA, a CD calculator compares guaranteed, fixed-term returns. You can also cross-check a taxable account with our investment calculator.
