Roth IRA Calculator

Can I contribute to both Roth and Traditional IRAs?

Yes, but your combined contributions are capped at $7,000/year ($8,000 at 50+). If you contribute $5,000 to a Roth, you can contribute only $2,000 to a Traditional IRA. Plan strategically—most people benefit from prioritizing Roth if eligible.

What's a backdoor Roth and should I do one?

A backdoor Roth lets high-income earners bypass income limits: contribute to a Traditional IRA, immediately convert to Roth. This is legal and commonly used. However, it's complex (watch the pro-rata rule with existing IRAs) and may trigger taxes. Consult a tax professional before executing. If high-income, it's often worth the complexity to access Roth benefits.

Can I withdraw my contributions anytime?

Yes—Roth contributions (your actual deposits) can be withdrawn anytime tax and penalty-free. Earnings are different: withdrawals before 59.5 cost 10% penalty plus taxes (with exceptions for disability, first-time home purchase, etc.). Keep earnings untouched until retirement to maximize tax-free growth.

What if my income is too high for Roth IRA?

2024 income limits: single $146,000-$161,000, married $230,000-$240,000. If over limits, use a backdoor Roth. If self-employed, consider a Solo 401(k) or SEP IRA instead. You have options—don't assume you can't save in tax-advantaged accounts.

Are there required minimum distributions (RMDs) from Roth IRAs?

No—Roth IRAs have no RMDs during your lifetime. You can let them grow tax-free indefinitely. This is a major advantage over Traditional IRAs (which require withdrawals starting at 73). You control when you withdraw, allowing maximum compounding.

Roth vs. Traditional IRA—which is better?

Roth is generally better for younger workers (more earning years ahead = more valuable tax-free growth), lower current earners (pay taxes now at lower rate than future), and high-income earners expecting higher retirement taxes. Traditional is better if you need current tax deductions or expect lower retirement tax brackets. For most workers under 50 with decades until retirement, Roth wins.

Can I invest in anything in a Roth IRA?

You can invest in stocks, bonds, mutual funds, ETFs, and some alternative investments. Cannot invest in collectibles, life insurance, or certain other assets. Choose based on risk tolerance: young workers should favor stocks (higher long-term returns); older workers should increase bonds. Use this calculator to model different return assumptions for your expected asset allocation.

What if I need money before retirement?

Withdraw Roth contributions (your deposits) anytime. You can also withdraw earnings penalty-free for first-time home purchase (up to $10,000 lifetime) or certain other exceptions. Generally though, use Roth as untouchable long-term savings—emergency funds should come from separate savings accounts.

The Tax Advantage: Why Tax-Free Growth Compounds Differently

Roth IRAs allow your investment earnings to compound completely tax-free. In taxable accounts, you pay taxes annually on dividends and capital gains (capital gains: 0-20% long-term, 37% short-term depending on bracket). This annual tax drag accumulates massively over decades. Example: $100,000 invested at 8% annual return for 30 years becomes $1,006,000 tax-free in a Roth. In a taxable account with 22% annual tax on gains, final value is only $667,000—a $339,000 difference from taxes alone!

This is Roth's true power: compounding happens on your full balance without annual tax leakage. The longer your time horizon, the more valuable this tax-free compounding becomes—which is why younger workers benefit most from Roth.

Income Limits and Backdoor Roth Strategies

Roth IRA eligibility phases out at income thresholds (2024: $146,000-$161,000 single). High-income earners lose access. However, a backdoor Roth provides a legal workaround: (1) Contribute $7,000 to a Traditional IRA (non-deductible), (2) Immediately convert to Roth. The backdoor works because conversions have no income limits—only contributions do.

Critical caveat: the pro-rata rule applies. If you have existing Traditional IRA balances, backdoor Roth contributions trigger taxes. Strategy: if you have $50,000 in Traditional IRAs and contribute $7,000 for backdoor Roth, you owe taxes on a pro-rata portion. Consult a tax professional before executing.

Catch-Up Contributions and Late-Start Savers

At age 50, you can contribute an additional $1,000 annually ($8,000 total). This is designed to help older workers accelerate catch-up. Combined with potentially higher salaries at age 50+, workers can significantly boost retirement savings in their final working years. A $8,000/year contribution from age 50-65 (15 years) at 7% returns accumulates $202,000—meaningful additional retirement wealth from catch-up contributions alone.

No Required Minimum Distributions: A Unique Advantage

Traditional IRAs require withdrawals starting at age 73 (RMD rules). Roth IRAs have zero RMD requirement. You can let a Roth grow tax-free indefinitely, withdrawing whenever you choose. This is powerful for legacy planning: if you die with a Roth IRA, heirs inherit it tax-free. A Traditional IRA inherited by heirs triggers immediate tax liability on distributions. Over decades, Roth inheritance advantage compounds to enormous wealth transfer differences.

Additionally, the no-RMD feature means you control timing of withdrawals. If some years you have low income, you can strategically withdraw (tax-free), keeping total income low and preserving Social Security benefits. Traditional IRA RMDs force withdrawals at times you might not want them. Control matters in retirement tax planning.

Contribution vs. Earnings: The Critical Distinction

Roth allows penalty-free withdrawal of contributions (your deposits) anytime. Earnings are restricted until 59.5 (with exceptions: first-time home purchase up to $10,000, disability, etc.). This distinction means Roth partially functions as emergency savings: if desperate, you can access contributions without penalty. However, this should never be your primary strategy—emergency funds belong in savings accounts, not retirement accounts.

A common strategy: maximize Roth contributions, letting earnings compound untouched. Contributions can theoretically be withdrawn if life emergency occurs, but the goal is keeping all money invested for decades of tax-free compounding.

Roth as Wealth Transfer and Legacy Planning

Roth IRAs are powerful legacy vehicles because heirs inherit them tax-free and can withdraw tax-free over their lifetime (under SECURE Act 2.0 rules, heirs must distribute within 10 years, but distributions are still tax-free). A parent leaves $500,000 in a Roth—the child inherits $500,000 tax-free, no tax liability. Compare to Traditional accounts: same $500,000 triggers immediate tax liability for heirs (potentially $110,000 in taxes at 22% bracket).

For wealthy individuals focused on leaving wealth to heirs, Roth represents the most tax-efficient transfer vehicle. Maximize Roth contributions early, let compound for decades, pass to heirs completely tax-free. No other investment vehicle matches this legacy-building power.

Asset Allocation in Roth: Maximize Growth Potential

Because Roth earnings are tax-free, it should contain your highest-growth, highest-volatility investments. Bonds with taxable interest should go in taxable accounts (you can deduct losses). Stocks with capital gains should go in Roth (all gains are tax-free). Tax-inefficient investments (actively-traded portfolios, REITs) also belong in Roth since there's no tax consequences for turnover.

Strategic asset location (choosing account types based on tax efficiency) multiplies Roth's advantage. A Roth containing stock index funds (high growth, tax-free) compounds far more powerfully than if it held bonds (lower growth, but taxable interest would be avoidable anyway).

Roth vs. Traditional: The Decision Framework

Choose Roth if: (1) You're under 50 and have 20+ years to retirement (maximum compounding time), (2) You expect higher tax bracket in retirement than now, (3) You expect high future income (which restricts Traditional IRA deductions), (4) You want flexibility (no RMDs, can access contributions). Choose Traditional if: (1) You're near retirement and want current tax deductions, (2) You expect lower tax bracket in retirement, (3) You need the immediate tax savings to maximize contributions.

For most workers under 50: Roth wins. You have decades for tax-free compounding, and it's unlikely your retirement tax bracket will be lower than your current bracket. Roth also provides flexibility and no RMD concerns. This calculator helps you quantify the difference in your specific situation.

The Math: Why Starting Early Matters Most in Roth

A $7,000 contribution at age 25 in a Roth growing 8% for 40 years to retirement becomes $380,000 at retirement—$373,000 of which is tax-free growth. The same $7,000 at age 35 becomes $187,000. Starting 10 years earlier doubled the final value and more than doubled the tax-free growth component.

This exponential time advantage means a 25-year-old investing $2,000/year in a Roth accumulates more wealth than a 35-year-old investing $7,000/year. Time is Roth's most powerful variable. If you have even modest income and decades until retirement, prioritize Roth contributions above almost everything else.
