About the IRA Calculator
IRA Calculator helps estimate the key numbers involved in retirement decisions. It is designed for quick scenario comparison: enter a realistic set of values, calculate the result, then change one assumption at a time to see what has the greatest effect. Unlike a static table, the result responds to your inputs and keeps the calculation in your browser. Amounts are displayed in U.S. dollars for consistency, but the mathematical formulas can be used with another currency when every monetary input uses that same currency.
How to use this calculator
Enter values that match your situation and select Calculate result. Review the main result and its supporting figures, then change one input at a time to compare scenarios. Results are rounded for readability while the calculation retains additional precision internally.
Information you will need
- Starting amount
- Monthly contribution
- Annual return
- Years
How the calculation works
Projects growth with monthly compounding and contributions. Read the primary result together with the supporting values rather than focusing on one number alone. A useful estimate should make its assumptions visible. If the answer looks surprising, verify the unit, rate, time period, and whether the entered value is gross or net. Run a conservative and an optimistic scenario to understand the range of possible outcomes.
Formula or method
FV = P(1+r)n + C((1+r)n - 1)/r.
Worked example
$10,000 + $250/month at 7% for 10 years.
The example is illustrative rather than a recommendation. Use your own verified values and keep all monetary or measurement units consistent. When comparing alternatives, save or note each result so the assumptions do not become mixed.
How to interpret the result
The primary output answers the main question posed by the ira calculator, while the additional cards provide context. A result with many decimal places is not necessarily more certain. The displayed precision makes comparison easier, but uncertainty in the inputs can be larger than the rounding difference.
Compare the result with a second scenario using a less favorable rate, return, cost, or time period. This sensitivity check often provides more useful planning information than one best-case projection.
Limitations and important notes
The ira calculator is a planning tool, not a quote, filing calculation, lending decision, or promise of future performance. It does not automatically retrieve live market rates or apply every fee, tax bracket, program rule, product limit, or state law. Rules for products such as FHA, VA, Social Security, retirement accounts, and taxes can change. Confirm time-sensitive values with the lender, plan administrator, IRS, SSA, or another relevant authority before acting.
Frequently asked questions
What is an IRA?
An IRA, or individual retirement account, is a tax-advantaged account you open yourself at a brokerage, bank, or fund company, separate from an employer plan. There are two main types: traditional IRAs, where contributions may be tax-deductible and withdrawals are taxed, and Roth IRAs, where contributions are after-tax and qualified withdrawals are free. IRAs allow you to invest in stocks, bonds, ETFs, and mutual funds, and you choose the investments. For 2025 you can contribute up to $7,000, or $8,000 if you are 50 or older.
What are the IRA contribution limits?
For 2025, the combined limit for all traditional and Roth IRAs is $7,000, or $8,000 if you are age 50 or older. For 2026, the limits rise to $7,500 and $8,600. You cannot contribute more than your earned income for the year, and contributions above the limit trigger a 6 percent excise tax each year until corrected. These limits are shared across all your IRAs, so the cap is not per account. The limits are indexed to inflation and change yearly, so always check the current figures.
What is the difference between a traditional and Roth IRA?
A traditional IRA may give you a tax deduction when you contribute, then taxes your withdrawals in retirement as ordinary income, and generally requires required minimum distributions starting at age 73 or 75. A Roth IRA gives no deduction, but your contributions and investment earnings can be withdrawn tax-free after age 59 1/2 and a five-year period, and Roth accounts have no RMDs. Traditional IRAs have no income limits for contributing, though deductibility phases out if you have a workplace plan; Roth IRAs have direct income limits.
When can I withdraw from my IRA without penalty?
You can withdraw from a traditional IRA without the 10 percent early-withdrawal penalty after age 59 1/2, though the money is still taxable. Exceptions allow penalty-free withdrawals for a first-time home purchase up to $10,000, qualified higher-education expenses, unreimbursed medical costs above 7.5 percent of adjusted gross income, disability, and substantially equal periodic payments. Roth IRA contributions can be taken out anytime. The penalty does not apply to account holders with a qualifying exception, but income tax may still be owed on traditional IRA earnings.
What happens to my 401(k) when I roll it into an IRA?
Rolling a 401(k) into an IRA moves your retirement savings to an account you control without triggering taxes or penalties, as long as it is a direct transfer. You gain a wider choice of investments, lower fees in many cases, and the option to convert to a Roth later. One downside is that IRA money may not be protected from lawsuits the way employer plans are under federal law. Avoid taking a check yourself, because 20 percent withholding may apply and you risk a taxable distribution.
How much will my IRA be worth at retirement?
Your IRA value at retirement depends on your annual contribution, your investment return, and how many years it grows. Contributing the full $7,000 each year at a 7 percent average return for 30 years grows to roughly $660,000, while waiting until age 50 to start cuts that total dramatically. Most planners model 6 to 8 percent nominal returns for a stock-heavy portfolio over a long time horizon. An IRA calculator can project different scenarios by age, contribution amount, and assumed return.
Can I contribute to both a 401(k) and an IRA?
Yes, you can contribute to both a 401(k) and an IRA in the same year because each has its own separate contribution limit. For 2025 you could put $23,500 in a 401(k) plus $7,000 in an IRA. However, if you are covered by a workplace plan, your traditional IRA deduction phases out based on income, around $79,000 to $89,000 for single filers and $126,000 to $146,000 for married couples filing jointly in 2025. A Roth IRA avoids the deduction issue but has its own income limits.
