What Is an IRA? A Plain-English Explanation
An Individual Retirement Account (IRA) is a tax-advantaged investment account available to anyone in the United States with earned income. Congress created IRAs to encourage Americans to save for retirement outside of employer-sponsored plans. Unlike a 401(k), which is offered by your employer, an IRA is something you open yourself—at a brokerage, bank, credit union, or robo-advisor.
The two most common types are the Traditional IRA and the Roth IRA, and they differ primarily in when you get the tax break: Traditional IRAs may give you a deduction today; Roth IRAs give you tax-free income in retirement. Both grow tax-advantaged while the money stays inside the account, which is the real engine of long-term wealth.
According to the Investment Company Institute, over 40% of U.S. households own at least one IRA, and the average IRA balance was roughly $116,000 as of the most recent published data—though balances vary enormously by age, income, and contribution history. The IRA calculator above helps you project where your balance could land given your specific inputs.

2026 IRA Contribution Limits — Updated
The IRS adjusts IRA contribution limits periodically for inflation. For tax year 2026, the limits are as follows. Note the new enhanced catch-up for ages 60–63, which was introduced by the SECURE 2.0 Act of 2022 and took full effect in 2025–2026:
2026 IRA Contribution Limits at a Glance
These limits apply to combined contributions across all your IRAs. You cannot contribute more than you earned in wages, salaries, or self-employment income—so if you only earned $4,000 this year, your IRA contribution limit is $4,000, not $7,000.
⚠️ Spousal IRA Exception
A non-working spouse can still contribute to an IRA as long as the other spouse has enough earned income to cover both contributions. A married couple can collectively contribute up to $14,000 (or $16,000–$20,000 with catch-ups) using spousal IRA rules.
Roth IRA vs Traditional IRA: Complete Side-by-Side Comparison
The Roth vs Traditional IRA decision is one of the most important choices in personal finance. Both accounts grow your money tax-advantaged, but the timing and type of tax break differs significantly. Here is a comprehensive comparison:
When a Traditional IRA Makes More Sense
Choose a Traditional IRA if you expect to be in a lower tax bracket in retirementthan you are today. This is common for high-income earners in peak earning years (late 40s–50s). Taking the deduction now at a 24% or 32% marginal rate and paying taxes in retirement at 12% or 22% is a net win. The Traditional IRA is also beneficial if you do not qualify for a Roth IRA due to income limits and cannot access a backdoor Roth.
When a Roth IRA Makes More Sense
Choose a Roth IRA if you expect to be in the same or higher tax bracket in retirement, or if you value flexibility. Young workers in the 10%–22% bracket today benefit enormously from locking in taxes at low rates now. The Roth is also ideal if you want to leave tax-free money to heirs or want to avoid forced RMDs in retirement.
2026 Roth IRA Income Limits & Phase-Out Ranges
Roth IRA eligibility phases out at higher incomes. Your ability to contribute is based on your Modified Adjusted Gross Income (MAGI)—essentially your AGI plus certain deductions added back. Here are the updated 2026 thresholds:
If your income falls inside the phase-out range, you can still make a partial Roth IRA contribution. Use this formula to estimate your reduced limit:
For example: A single filer with a $155,000 MAGI in 2026 falls $5,000 into the $15,000 phase-out range. Their reduced limit = $7,000 × (1 − 5,000/15,000) = $4,667.
IRA Growth Projections: What Maxing Out Your IRA Actually Looks Like
The following table shows what happens when you consistently contribute the annual IRA maximum ($7,000/year) starting from a $0 balance, assuming a 7% average annual return(approximately the historical inflation-adjusted return of a broad U.S. stock index). These numbers illustrate the compounding effect—often called the "eighth wonder of the world."
Assumptions: $7,000/year contribution, 7% annual return, annual compounding, no taxes withheld (Roth scenario or Traditional tax not shown). For illustrative purposes only.
Notice that after 40 years, your $280,000 in contributions has grown to over $1.47 million— more than five times your money, with $1.2 million created entirely by investment returns. This is the compounding engine at work. Starting even five years earlier can add hundreds of thousands of dollars to your final balance.
💡 The $10/Day Rule
Contributing $7,000/year breaks down to roughly $583/month, or about $19/day. For a 25-year-old who starts today and retires at 65, that $19/day could become over $1.47 million— entirely within tax-advantaged shelter. Use the compound interest calculator to model different contribution amounts.
IRA Investment Options: What Can You Hold Inside an IRA?
One of the biggest advantages IRAs have over workplace 401(k) plans is investment flexibility. Most 401(k) plans restrict you to a curated list of 10–30 funds. IRAs at major brokerages give you access to virtually the entire investment universe:
Index Funds & ETFs
⭐ Most RecommendedThe gold standard for most retirement savers. Low-cost funds like VTSAX, VTI, or SPY give you broad market diversification at minimal expense. Expense ratios of 0.03%–0.10% leave more of your returns compounding.
Target-Date Funds
🎯 Hands-OffSet-and-forget option that automatically shifts from stocks toward bonds as your retirement year approaches. Perfect if you want a hands-off approach. Look for "2045," "2050," or "2055" funds.
Individual Stocks
Buy shares of any publicly traded U.S. or international company. Offers higher potential returns but requires more research and monitoring. Best as a portion of a diversified portfolio.
Bonds & Bond Funds
Government (Treasuries), municipal, and corporate bonds. Provide stability and income. Especially valuable as you approach retirement and want to reduce volatility.
REITs
Real Estate Investment Trusts let you invest in real estate without buying property. They pay high dividends—which are taxed as ordinary income—making them especially efficient inside a tax-deferred IRA.
CDs & Money Market
FDIC-insured options with no market risk. Returns are predictable but typically lower than equities. Suitable for very short time horizons or the most conservative savers.
What you cannot hold in a standard IRA: Collectibles (art, antiques, coins with exceptions), life insurance contracts, and S-corporation stock. Self-directed IRAs allow alternative investments like real estate or private equity, but they come with complex rules and custodian fees.
IRA Withdrawal Rules, Early Withdrawal Penalties & Exceptions
IRAs are designed for retirement, so the IRS penalizes most early withdrawals. Understanding the rules can save you thousands in unnecessary taxes and penalties.
Traditional IRA Withdrawals
After age 59½
Taxed as ordinary income. No penalty.
Before age 59½
10% early withdrawal penalty PLUS ordinary income tax on the full amount.
Required at age 73
RMDs are mandatory. Missing an RMD triggers a 25% excise tax (reduced to 10% if corrected within 2 years).
Roth IRA Withdrawals
Roth IRA withdrawals have a unique two-layer structure: contributions (money you put in) and earnings (growth):
- Contributions: Can be withdrawn at any age, at any time, completely tax-free and penalty-free. No waiting period.
- Earnings before 59½: Subject to 10% penalty and income tax unless an exception applies.
- Earnings after 59½ and 5-year rule met: Completely tax-free and penalty-free.
Penalty Exceptions — Both IRA Types
The IRS waives the 10% early withdrawal penalty (but not the income tax) in these situations:
IRA vs 401(k): Which Should You Fund First?
Most financial advisors recommend a prioritization ladder. Here's the optimal order for allocating your retirement dollars:
401(k) Up to the Employer Match
Free money. A 50% or 100% match is an immediate 50%–100% return on your contribution. Never leave this on the table.
Max Out Your IRA ($7,000 in 2026)
IRAs offer broader investment choices than most 401(k) plans. Low-cost index funds beat many 401(k) fund lineups on fees.
Max Out Your 401(k) ($23,500 limit in 2026)
After your IRA is maxed, push your 401(k) to the full annual limit. More tax-advantaged space is always beneficial.
Taxable Brokerage Account
Once all tax-advantaged space is used, invest in a regular brokerage account. No limits, no tax benefits, but full flexibility.

Backdoor Roth IRA Strategy: How High Earners Access Tax-Free Growth
If your income exceeds the Roth IRA limits, the backdoor Roth IRA is a perfectly legal strategy to access Roth benefits. Here is exactly how it works:
Contribute to a Traditional IRA (Non-Deductible)
Make a $7,000 (2026) non-deductible contribution to a Traditional IRA. There is no income limit for Traditional IRA contributions. Because you take no deduction, your cost basis in the IRA equals your contribution.
Convert to a Roth IRA
Shortly after (often within days to minimize earnings), convert the Traditional IRA to a Roth IRA. Because your basis equals your contribution and there are minimal or no earnings, the taxable amount is near zero.
File IRS Form 8606
This form tracks your non-deductible basis in Traditional IRAs. Filing it annually is critical to avoid being double-taxed on withdrawals.
⚠️ Beware the Pro-Rata Rule
If you have other pre-tax IRA money (from a rollover or deductible contributions), the IRS treats all your Traditional IRA funds as a single pool when calculating the taxable portion of your conversion. For example, if you have $63,000 pre-tax and contribute $7,000 non-deductible, only 10% of any conversion is tax-free (7,000 ÷ 70,000). A tax professional can help you navigate this.
Required Minimum Distributions (RMDs): What You Need to Know
The IRS does not let Traditional IRA money grow tax-deferred forever. Starting at age 73, you must withdraw a minimum amount each year—your Required Minimum Distribution. Failure to take your RMD triggers a 25% excise tax on the amount not withdrawn (reduced to 10% if you correct within 2 years under SECURE 2.0).
Your RMD is calculated each year as:
At age 73, the life expectancy factor is approximately 26.5, so a $500,000 IRA would require an RMD of roughly $18,868 in year one. The factor decreases each year, requiring larger percentage withdrawals as you age.
Use our dedicated RMD Calculator to estimate your specific Required Minimum Distributions. Remember: Roth IRAs have no RMDs during the original owner's lifetime, which makes Roth conversions in your 60s a powerful estate planning and tax management strategy.
10 Tips to Maximize Your IRA and Retire Wealthier
Start as early as possible
Every decade you delay roughly halves your final balance due to lost compounding. A 25-year-old who contributes for just 10 years and stops often accumulates more than a 35-year-old who contributes for 30 years.
Automate your contributions
Set up automatic monthly transfers so you contribute consistently throughout the year rather than scrambling to fund your IRA before the April deadline.
Invest in low-cost index funds
A 1% annual fee difference may seem small, but over 30 years it can cost you 25%+ of your final balance. Vanguard, Fidelity, and Schwab all offer index funds with expense ratios under 0.05%.
Use the spousal IRA if your spouse doesn't work
A non-working spouse can contribute up to $7,000/year to their own IRA as long as you file jointly and have enough earned income.
Consider Roth conversions in low-income years
Between jobs, early retirement, or a year with large deductions? Convert Traditional IRA assets to Roth at your temporarily lower rate.
Use the backdoor Roth if you earn too much
High earners can still access Roth benefits through the two-step backdoor strategy described above.
Rebalance annually
Once a year, review your allocation and adjust back to your target. Left unattended, a strong stock market can push your portfolio to an overly aggressive allocation.
Don't withdraw early
Between the 10% penalty and income taxes, an early withdrawal from a Traditional IRA can cost you 40%+ of the amount. Explore all alternatives first.
Name beneficiaries and update them
IRA beneficiary designations override your will. Review them after every major life event—marriage, divorce, birth, or death.

Real-Life Example: Sarah vs Marcus — Two IRA Strategies Compared
Let's compare two people to illustrate the impact of IRA type and timing:
Sarah — Traditional IRA
- • Age: 40 | Income: $95,000
- • Contributes $7,000/year (deductible)
- • Current tax bracket: 22%
- • Expected retirement bracket: 12%
- • Annual tax savings on contribution: $1,540
- • Projected balance at 65: $474,000
- • After-tax value (12% on withdrawals): ~$417,000
Marcus — Roth IRA
- • Age: 40 | Income: $95,000
- • Contributes $7,000/year (no deduction)
- • Current tax bracket: 22%
- • Expected retirement bracket: 22%
- • Annual tax savings on contribution: $0
- • Projected balance at 65: $474,000
- • After-tax value (tax-free): $474,000 ✅
In this example, Marcus comes out ahead because his tax bracket doesn't change. But if Sarah's bracket drops significantly in retirement, the deductions make Traditional IRA the winner. The key insight: future tax rates are unknown, which is why many advisors recommend diversifying between both Roth and Traditional accounts to hedge tax-rate risk.
