IRA Calculator

About IRA Calculator

An IRA calculator is an essential retirement planning tool that helps you compare different types of individual retirement accounts side by side. Unlike simple savings calculators, this IRA calculator factors in the tax treatment of each account type, showing you both before-tax and after-tax values so you can make an informed decision about which retirement savings strategy works best for your situation.

In the United States, an IRA (individual retirement account) is a type of retirement plan with taxation benefits defined by IRS Publication 590. It is a government tax break to incentivize people to invest money for retirement. Among the different IRAs, the most common are traditional IRAs and Roth IRAs. The contributions to a Roth IRA are not tax-deductible, but the withdrawals after retirement are tax-free. Conversely, the contributions to a traditional IRA are tax-deductible but are taxed on withdrawals after retirement. This calculator also supports SEP IRAs for self-employed individuals and SIMPLE IRAs for small businesses.

This IRA calculator compares four scenarios simultaneously: Traditional IRA (which includes SEP and SIMPLE IRAs), Roth IRA, and regular taxable savings. It converts all values to after-tax amounts for a fair comparison, accounting for your current tax rate, expected retirement tax rate, and the number of years until retirement. The results are displayed in an easy-to-read comparison grid and an accumulation chart that shows how each account type grows over time. Use this calculator alongside our retirement calculator to build a comprehensive retirement plan.

Traditional IRA

As the most common IRA in use, traditional IRAs are qualified retirement plans that have tax shields in place for funds set aside for retirement. They are ideal for people who want to reduce a tax bill while at the same time saving for retirement. Contributions to a Traditional IRA are tax-deductible in the year they are made, reducing your current taxable income. The money grows tax-deferred, meaning you pay no taxes on investment gains until you withdraw the funds in retirement.

Taxation only occurs when withdrawing before or in retirement. However, early withdrawals before age 59½ will be penalized with a 10% additional tax, except in qualified cases such as first-time home purchases up to $10,000, qualified education expenses, or certain medical expenses. The contributions made are tax-deductible for most people as long as several requirements, dependent on tax-filing status and gross income, are met. If you or your spouse is covered by a workplace retirement plan, the deduction may be phased out at higher income levels.

The key advantage of a Traditional IRA is the immediate tax savings. If you are in the 25% tax bracket and contribute $7,500, you save $1,875 on your tax bill that year. That money can then be invested elsewhere, potentially growing further. However, in retirement, your withdrawals are taxed as ordinary income at whatever tax rate applies at that time. If you expect to be in a lower tax bracket in retirement, the Traditional IRA typically comes out ahead because you save taxes at a higher rate now and pay them at a lower rate later.

Roth IRA

Roth IRAs are often initiated and managed by individuals with contributions coming from after-tax income or assets. While you do not get an upfront tax deduction, the tax benefits on the back end are substantial. Investment income grows completely tax-free, and qualified withdrawals in retirement are also tax-free. After turning age 59½, withdrawals from Roth IRAs are penalty-free, provided the account has been open for at least five years.

One of the most powerful features of a Roth IRA is that withdrawals are not mandatory during the owner's lifetime. Unlike Traditional IRAs which require Required Minimum Distributions (RMDs) starting at age 73, Roth IRAs have no RMDs. Without distribution, Roth IRAs can grow tax-free throughout the owner's entire lifetime and be passed to heirs, who can also enjoy tax-free growth and withdrawals. This makes the Roth IRA an exceptional estate planning tool.

Roth IRAs do have income limits. For 2026, the ability to contribute phases out for single filers with modified AGI between $150,000 and $165,000, and for married couples filing jointly between $236,000 and $246,000. If your income exceeds these limits, you may still be able to contribute via the backdoor Roth IRA strategy, which involves making a non-deductible Traditional IRA contribution and then converting it to a Roth IRA. This calculator helps you compare the after-tax value of a Roth IRA against a Traditional IRA, accounting for your specific tax situation.

SEP IRA

Simplified Employee Pension (SEP) IRAs, which are initiated by employers, allow employers to make contributions to the IRA accounts of their employees. SEP IRAs are mostly used by small businesses or self-employed individuals because they are easy to set up, have low administrative costs, and offer high contribution limits. Employers can contribute to SEP IRAs for themselves and their employees, and all contributions are tax-deductible for the business.

Contribution limits for 2026: The lesser of 25% of gross income, or $72,000. There is no catch-up contribution for account holders age 50 or older. Unlike Traditional and Roth IRAs, only employers can contribute to SEP IRAs, not employees. Employees are immediately 100% vested in all SEP IRA contributions, meaning they own the full amount from day one. The funds grow tax-deferred and are taxed as ordinary income upon withdrawal in retirement, similar to a Traditional IRA.

SEP IRAs are particularly attractive for self-employed individuals and freelancers who want to save more for retirement than the Traditional or Roth IRA limits allow. Because the contribution limit is based on compensation, high-income self-employed individuals can contribute substantial amounts each year. The SEP IRA functions identically to a Traditional IRA from an investment perspective, so this calculator treats them the same way for the growth and tax projections.

SIMPLE IRA

Savings Incentive Match Plan for Employees (SIMPLE) IRAs are mainly designed for small businesses with 100 or fewer employees. For this retirement plan, employers must choose between two matching options: matching employee contributions dollar-for-dollar up to 3% of compensation, or making a fixed non-elective contribution of 2% of compensation for all eligible employees regardless of whether they contribute. The SIMPLE IRA is easier to administer than a 401(k) plan, making it an attractive option for small businesses.

Annual contribution limits for 2026: $17,000 ($22,250 if age 50 or older, $23,500 if age 60-63). These limits are higher than Traditional and Roth IRAs but lower than 401(k) and SEP IRA limits. Employees can make salary deferral contributions, and employers must make either the matching or non-elective contribution each year. Like Traditional IRAs, SIMPLE IRA funds grow tax-deferred and are taxed as ordinary income upon withdrawal.

One important distinction is that SIMPLE IRAs have a higher early withdrawal penalty than Traditional IRAs. If you withdraw funds within the first two years of participating in the plan, the early withdrawal penalty is 25% instead of the standard 10%. After the two-year period, the penalty reverts to 10%. This calculator treats SIMPLE IRAs the same as Traditional IRAs for projection purposes since the tax treatment and growth mechanics are identical.

Comparison to 401(k)s

Traditional IRAs and 401(k)s are two of the most popular tax-deferred, defined contribution retirement plans in the United States. Both turn pre-tax income into tax-deductible contributions that are placed into retirement plans that receive tax-sheltered growth. However, there are important differences that affect your retirement planning strategy.

For 2026, the maximum contribution towards a 401(k) is $24,500 ($31,000 if age 50 or older), compared to $7,500 ($8,600 if age 50 or older) for Traditional and Roth IRAs. This makes 401(k) plans the clear choice for maximizing retirement savings. Additionally, many employers offer matching contributions on 401(k) plans, which is essentially free money. A typical match might be 50% of your contributions up to 6% of your salary, which adds significantly to your retirement savings.

A common recommendation is to follow this order of prioritization: first, contribute enough to your 401(k) to get the full employer match. Second, max out a Roth or Traditional IRA for more investment choices and lower fees. Finally, return to your 401(k) to contribute additional savings. This strategy maximizes both the free money from employer matching and the investment flexibility of IRAs. Use our 401k calculator to model your employer-sponsored retirement plan growth alongside this IRA calculator.

Common Mistakes to Avoid With IRAs

Not contributing early enough. The power of compound growth means that starting even a few years earlier can make a dramatic difference. A $7,500 annual contribution earning 6% grows to approximately $837,000 over 35 years, but only about $437,000 over 25 years. The ten-year delay costs nearly $400,000 in potential growth.

Choosing the wrong IRA type. Picking a Traditional IRA when a Roth IRA would be better, or vice versa, can cost you thousands in unnecessary taxes. This calculator helps you compare the after-tax values of each type side by side based on your current and expected future tax rates. Generally, Roth IRAs are better if you expect higher taxes in retirement, while Traditional IRAs win if you expect lower taxes.

Forgetting to rebalance. Over time, your IRA investments will drift from your target allocation. Annual rebalancing helps maintain your desired risk level and can improve returns by systematically selling assets that have performed well and buying those that have lagged.

Ignoring the Roth IRA income limits. If your income exceeds the Roth IRA contribution limits, you may accidentally contribute too much and face penalties. Use the backdoor Roth IRA strategy instead, which has no income limits.

Taking early withdrawals. Early withdrawals from Traditional IRAs trigger both income taxes and a 10% penalty, which can consume a large portion of your savings. Avoid tapping your IRA before retirement whenever possible, and use this calculator to see the long-term cost of early withdrawals.

Five Tips for Maximizing Your IRA

1. Start as Early as Possible

Time is your most powerful ally in retirement investing. A 25-year-old who contributes $7,500 annually for 10 years and then stops will likely have more at retirement than a 35-year-old who contributes the same amount annually for 30 years, thanks to the magic of compounding. Start early and let time work for you.

2. Max Out Your Contributions

If possible, contribute the maximum allowed each year. For 2026, that is $7,500 ($8,600 if 50 or older). If you cannot max out, at least contribute enough to get any employer match in your 401(k) first. Increasing your contribution by just 1% of your income each year can significantly boost your retirement savings without feeling like a large sacrifice.

3. Use the Right IRA for Your Situation

Use this IRA calculator to compare Traditional versus Roth outcomes based on your specific tax situation. If you are in a low tax bracket now, the Roth IRA's tax-free withdrawals may be more valuable. If you are in a high tax bracket, the Traditional IRA's upfront deduction may be better. You can also contribute to both types as long as the combined total does not exceed the annual limit.

4. Invest for Growth

Because IRAs are long-term accounts, you can afford to take more risk and invest for growth. A portfolio of low-cost stock index funds has historically returned 7-10% annually over long periods. Avoid being too conservative with your IRA investments, especially when you are young and have decades until retirement.

5. Consider a Backdoor Roth IRA

If your income exceeds the Roth IRA limits, do not give up on Roth savings. The backdoor Roth IRA strategy involves making a non-deductible Traditional IRA contribution and immediately converting it to a Roth IRA. This strategy is legal and widely used, and it has no income limits. Consult a tax professional to ensure you execute it correctly.

IRA Contribution Limits for 2026

Staying informed about the latest IRA contribution limits is essential for maximizing your retirement savings each year. The IRS periodically adjusts these limits based on inflation, and knowing the current figures helps you plan your contributions effectively. For 2026, the contribution limits have been adjusted upward, providing savers with increased opportunities to build their retirement nest eggs.

For Traditional and Roth IRAs combined, the 2026 contribution limit is $7,500 if you are under age 50. If you are age 50 or older, you can make an additional catch-up contribution of $1,100, bringing your total to $8,600. This catch-up provision is designed to help older savers accelerate their retirement savings as they approach retirement age. It is important to note that this is the combined limit across all your Traditional and Roth IRAs, not a per-account limit.

For SEP IRAs, the contribution limit for 2026 is the lesser of 25% of your compensation or $72,000. This makes SEP IRAs particularly attractive for self-employed individuals and small business owners with high incomes. Unlike Traditional and Roth IRAs, SEP IRA contributions are made solely by the employer, and the limits apply per employee. The funds grow tax-deferred and are taxed as ordinary income upon withdrawal, similar to a Traditional IRA.

SIMPLE IRA contribution limits for 2026 are $17,000 for regular contributions, with an additional $5,250 catch-up for those age 50 or older ($6,500 for those age 60-63). SIMPLE IRAs offer higher contribution limits than Traditional and Roth IRAs but lower than SEP IRAs and 401(k) plans, making them a middle-ground option for small business employees who want to save more than the basic IRA limit allows.

Understanding these limits is crucial for effective retirement planning. By maxing out your IRA contributions each year, you can take full advantage of the tax benefits and compound growth potential. Use this IRA calculator to project how different contribution levels affect your retirement savings over time, and adjust your savings strategy accordingly to make the most of the available limits each year.

How to Choose Between Traditional and Roth IRA

One of the most common questions retirement savers face is whether to choose a Traditional IRA or a Roth IRA. The answer depends on several factors unique to your financial situation, including your current tax bracket, expected future tax bracket, retirement timeline, and overall financial goals. This IRA calculator is specifically designed to help you make this decision by comparing after-tax values of each account type side by side.

The fundamental trade-off is about the timing of taxes. With a Traditional IRA, you receive a tax deduction now on your contributions, reducing your current year tax bill. The money grows tax-deferred, and you pay taxes on withdrawals in retirement at whatever your ordinary income tax rate is at that time. This is advantageous if you expect to be in a lower tax bracket in retirement than you are currently. For example, if you are in the 25% tax bracket now but expect to be in the 15% bracket in retirement, the Traditional IRA saves you 10% in taxes on every dollar contributed.

With a Roth IRA, you get no upfront tax deduction, but your money grows completely tax-free, and qualified withdrawals in retirement are also tax-free. This makes the Roth IRA ideal if you expect to be in a higher tax bracket in retirement or if you want to maximize the amount of tax-free income you have available. Young professionals early in their careers, who are often in lower tax brackets, can benefit enormously from locking in today's low tax rates with a Roth IRA and then enjoying decades of tax-free compounding.

Another important consideration is flexibility. Roth IRA contributions can be withdrawn at any time, for any reason, without taxes or penalties. This makes the Roth IRA a more flexible savings vehicle that can double as an emergency fund if needed. Traditional IRA withdrawals before age 59½ generally incur both income taxes and a 10% penalty, making them less suitable for early access. Additionally, Roth IRAs have no Required Minimum Distributions during the owner's lifetime, allowing the account to grow tax-free indefinitely for estate planning purposes.

Many financial experts recommend having both types of accounts for tax diversification in retirement. This strategy allows you to manage your taxable income by choosing which accounts to withdraw from each year. Our IRA calculator lets you model both scenarios simultaneously, showing you the projected after-tax value of each approach based on your specific tax rates and time horizon. Use it alongside our Roth IRA calculator for more detailed analysis of Roth savings strategies.

IRA Investment Strategies for Long-Term Growth

The investments you choose within your IRA play a critical role in determining your retirement outcomes. While the IRA calculator shows the power of compound growth, the actual returns you earn depend entirely on your investment choices. A well-diversified portfolio aligned with your risk tolerance and time horizon can significantly enhance your retirement savings over the long term, while poor investment choices can erode the tax advantages that IRAs provide.

For long-term retirement savers with a time horizon of 10 years or more, a portfolio heavily weighted toward stocks has historically provided the best returns. Low-cost broad market index funds that track the S&P 500 or total stock market indices have delivered average annual returns of approximately 7-10% over long periods. The key is to maintain a disciplined investment approach and avoid making emotional decisions during market downturns. Remember that market corrections are normal and historically have been followed by strong recoveries.

Dollar-cost averaging is another powerful strategy for IRA investing. By contributing regularly to your IRA each month or each year, you automatically buy more shares when prices are low and fewer when prices are high. This reduces the impact of market volatility on your overall portfolio and eliminates the need to time the market. Setting up automatic monthly contributions to your IRA ensures consistent investing discipline and takes advantage of compounding throughout the year rather than just at year-end.

As you approach retirement, gradually shifting your IRA investments toward a more conservative allocation can help protect your accumulated savings. A common rule of thumb is to subtract your age from 110 or 120 to determine the percentage of your portfolio that should be in stocks. For example, a 40-year-old might hold 70-80% in stocks and 20-30% in bonds, while a 65-year-old might hold 45-55% in stocks. This gradual de-risking helps balance growth potential with capital preservation as your retirement horizon shortens.

Within your IRA, you have access to virtually any investment available in the market, including stocks, bonds, mutual funds, exchange-traded funds (ETFs), and real estate investment trusts (REITs). Unlike 401(k) plans, which typically offer a limited menu of investment options, IRAs provide maximum flexibility. This is one of the key advantages of rolling over a 401(k) to an IRA when changing jobs. Consider using a compound interest calculator to see how different rates of return affect your long-term savings growth within your IRA.

For those using a Roth IRA, the tax-free growth makes it an ideal vehicle for holding investments that generate significant capital gains or dividends. Growth stocks and REITs particularly benefit from the tax-free compounding environment of a Roth IRA. With a Traditional IRA, the tax deferral means you defer taxes on all gains, but you eventually pay ordinary income tax rates on withdrawals. Review and rebalance your IRA portfolio annually to maintain your target asset allocation and stay on course toward a secure retirement.

IRA Withdrawal Rules and Penalties

Understanding the rules governing IRA withdrawals is essential for avoiding costly penalties and making informed decisions about when and how to access your retirement savings. Different IRA types have different withdrawal rules, and knowing these distinctions can save you thousands of dollars in taxes and penalties over your lifetime. This section covers the key rules you need to know for each IRA type.

For Traditional IRAs, withdrawals before age 59½ are generally subject to both ordinary income tax on the amount withdrawn and a 10% early withdrawal penalty. There are several important exceptions, including using the funds for a first-time home purchase (up to $10,000 lifetime), qualified higher education expenses, unreimbursed medical expenses exceeding 7.5% of your adjusted gross income, disability, or substantially equal periodic payments. If you become unemployed, you may also be able to withdraw funds for health insurance premiums without penalty.

Starting at age 73, Traditional IRA owners must take Required Minimum Distributions each year. The RMD amount is calculated based on your account balance and life expectancy factor provided by the IRS. Failing to take your RMD results in a steep penalty of 25% of the amount not withdrawn (reduced to 10% if corrected promptly). The SECURE Act 2.0 raised the RMD age to 73, and it will increase to 75 in 2033, giving retirees more flexibility in managing their retirement income in the coming years.

Roth IRAs offer significantly more favorable withdrawal rules. Contributions can be withdrawn at any time, for any reason, completely tax-free and penalty-free. This flexibility makes the Roth IRA a highly versatile savings vehicle. However, earnings withdrawals before age 59½ may be subject to both income tax and a 10% penalty unless a five-year aging period has been met and a qualified exception applies. After age 59½ and meeting the five-year requirement, all Roth IRA withdrawals are completely tax-free.

SEP IRAs and SIMPLE IRAs follow the same withdrawal rules as Traditional IRAs, with one important distinction for SIMPLE IRAs. If you withdraw funds within the first two years of participating in a SIMPLE IRA plan, the early withdrawal penalty is 25% instead of the standard 10%. After the two-year period, the penalty reverts to 10%. Strategic withdrawal planning can significantly impact your retirement income and tax liability, so consult with a tax professional to develop an optimal withdrawal strategy.

IRA Rollover Rules and Strategies

An IRA rollover allows you to move funds from one retirement account to another without triggering taxes or penalties, provided you follow the IRS rules carefully. The most common type of IRA rollover is moving funds from a 401(k) plan to a Traditional IRA when changing jobs. This is often recommended because IRAs typically offer more investment options, lower fees, and greater control over your retirement savings compared to employer-sponsored plans.

There are two main types of IRA rollovers: direct and indirect. A direct rollover transfers funds directly from one custodian to another, and the funds are never in your personal possession. This is the safest method and avoids any tax withholding requirements. An indirect rollover gives you the funds for up to 60 days to deposit them into another qualified account, but 20% may be withheld for taxes if the distribution is from a 401(k). You must replace the withheld amount with other funds to avoid taxes and penalties.

Roth conversions are another form of rollover where you convert Traditional IRA funds to a Roth IRA. The converted amount is treated as taxable income in the year of conversion, but future growth and withdrawals are tax-free. This strategy can be particularly advantageous in years when your income is lower than usual, allowing you to convert at a lower tax rate. There is no income limit for Roth conversions, making them available to all savers regardless of income level.

The one-rollover-per-year rule applies to indirect IRA-to-IRA rollovers. This rule limits you to one indirect rollover in any 12-month period, regardless of how many IRAs you own. Direct rollovers and Roth conversions are not subject to this limitation. Understanding these rules helps you avoid costly mistakes when moving retirement funds between accounts.

Final Thoughts: Start Your IRA Journey Today

Retirement planning is one of the most important financial endeavors you will undertake, and using an IRA calculator is an essential first step toward understanding your retirement savings potential. By comparing Traditional IRA, Roth IRA, SEP IRA, SIMPLE IRA, and taxable savings side by side, you gain valuable insights that can inform your retirement strategy and help you make confident decisions about your financial future.

The power of starting early cannot be overstated. Every year you delay contributing to an IRA represents lost compound growth potential. A $7,500 annual contribution earning 6% annual returns grows to over $1.1 million over 40 years, but only about $590,000 over 30 years. The difference of over $500,000 illustrates why the best time to start saving for retirement was yesterday, and the second best time is today. Use this IRA calculator to see the impact of starting now rather than later.

This calculator is designed to be your companion in this journey. Use it to model different scenarios: what happens if you increase your contribution rate? What if you delay retirement by a few years? How does changing your expected rate of return affect your projected outcomes? By running these scenarios, you can develop a retirement savings plan that aligns with your goals and risk tolerance. Experiment with the input fields above to see how different strategies change your projected retirement savings.

Remember that an IRA is just one component of a comprehensive retirement plan. Consider how it fits with your employer-sponsored 401(k), Social Security benefits, and other sources of retirement income. Explore our 401k calculator to model your employer-sponsored plan, use the savings calculator to set specific savings targets, and check the retirement calculator for a broader view of your retirement readiness.
