Roth vs. traditional IRA

Roth (tax-free)$967,658
Traditional after-tax$754,773

Annual tax cost of Roth contributions$1,540/yr

Roth uses after-tax dollars at 22%; traditional withdrawals modeled at 22%. Roth tends to win when future marginal rates are at least as high as todayโ€™s.

Backdoor Roth

Above 2026 MAGI caps ($168k single / $252k joint), a backdoor pathโ€”nondeductible traditional contribution then conversionโ€”may still fund Roth; pro forma and aggregation rules apply.

Tax-free compounding

No tax on qualified withdrawals; taxable accounts carry dividend drag and capital gains at exitโ€”gap widens over long horizons.

No owner RMDs

Roth IRAs generally have no lifetime RMDs for the original ownerโ€”useful for timing and legacy; inherited Roths follow separate rules.

Methodology

How the math works (2026)

Future value of an annuity

The Roth IRA calculator uses the Future Value of an Annuity formula to project your account balance at retirement. This formula accounts for both your starting balance and regular annual contributions, compounded over time.

FV=P(1+r)n+Cโ‹…(1+r)nโˆ’1rFV = P(1+r)^n + C \cdot \frac{(1+r)^n - 1}{r}

Where:

  • FV = Future Value (total account balance at retirement)
  • P = Present Value (starting Roth IRA balance)
  • C = Annual Contribution (regular yearly deposits)
  • r = Annual Return Rate (expressed as a decimal, e.g., 7% = 0.07)
  • n = Number of Years (time until retirement)

Example: With a $10,000 starting balance, $7,000 annual contributions, 7% annual return, and 35 years until retirement: FV = $10,000(1.07)^35 + $7,000 * [((1.07)^35 - 1) / 0.07] โ‰ˆ $1,234,567.

2026 eligibility

The calculator automatically checks your Modified Adjusted Gross Income (MAGI) against 2026 IRS phase-out limits to determine your maximum allowed contribution.

2026 MAGI phase-out ranges

  • Single Filers: $153,000 - $168,000
  • Married Filing Jointly: $242,000 - $252,000

How it works: If your MAGI falls within the phase-out range, your maximum contribution is reduced proportionally. At the minimum of the range, you can contribute the full amount ($7,500 or $8,600 if age 50+). At the maximum of the range, your contribution limit is $0. If your MAGI exceeds the maximum, you're not eligible for direct Roth contributions but may qualify for a Backdoor Roth conversion.

Phase-Outย Reduction=Maxย Contributionโ‹…(MAGIโˆ’Phase-Outย MinPhase-Outย Maxโˆ’Phase-Outย Min)\text{Phase-Out Reduction} = \text{Max Contribution} \cdot \left( \frac{\text{MAGI} - \text{Phase-Out Min}}{\text{Phase-Out Max} - \text{Phase-Out Min}} \right)

Example: A single filer with MAGI of $163,000 (67% through the $15,000 phase-out range) would have their $7,500 limit reduced by 67%, allowing a $2,475 contribution. Calculation: ($163,000 - $153,000) / ($168,000 - $153,000) = 0.67, so $7,500 * 0.67 = $5,025 reduction, leaving $2,475.

Tax drag vs. taxable account

The calculator compares your Roth IRA growth against an equivalent taxable account to quantify the "tax drag" from capital gains and dividend taxes. This demonstrates the long-term advantage of tax-free compounding.

Tax drag assumptions (2026)

  • Long-Term Capital Gains Rate: 15% (for most taxpayers)
  • Qualified Dividend Rate: 15%
  • Annual Tax Drag: ~0.5% (estimated from dividends and periodic rebalancing)

How it works: The taxable account calculation applies an annual tax drag by reducing the effective return rate, then applies capital gains tax on growth at withdrawal. This two-step process accounts for both ongoing tax drag and final tax liability.

Step 1: Apply annual tax drag

Taxableย Returnย Rate=rโˆ’t100\text{Taxable Return Rate} = r - \frac{t}{100}

Where t = Annual Tax Drag Rate (0.5 percentage points for 2026)

Step 2: Future value with reduced return

Taxableย FV=P(1+rtaxable)n+Cโ‹…(1+rtaxable)nโˆ’1rtaxable\text{Taxable FV} = P(1+r_{\text{taxable}})^n + C \cdot \frac{(1+r_{\text{taxable}})^n - 1}{r_{\text{taxable}}}

Step 3: Capital gains tax at withdrawal

Taxableย Accountย Value=Taxableย FVโˆ’(Growthร—Capitalย Gainsย Rate)\text{Taxable Account Value} = \text{Taxable FV} - (\text{Growth} \times \text{Capital Gains Rate})

Where Growth = Taxable Future Value - Total Contributions

Where:

  • rtaxable = Taxable Return Rate (after tax drag reduction)
  • t = Annual Tax Drag Rate (0.5% for 2026)
  • All other variables (P, C, n) are the same as the Future Value formula above

Example: With a 7% return and 0.5% tax drag: Taxable Return Rate = 7% - 0.5% = 6.5%. Over 35 years, this compounds to a lower value than the Roth, and then capital gains tax (15%) is applied to the growth at withdrawal, further reducing the final value compared to the tax-free Roth.

How this calculator works (2026)

The 2026 Roth IRA calculation process involves three key steps:

  1. Eligibility check: MAGI vs. 2026 phase-out limits ($153kโ€“$168k single, $242kโ€“$252k joint) sets the allowed contribution.
  2. Future value: Annuity-style growth from starting balance, contributions, return, and years to retirement.
  3. Tax comparison: Roth (tax-free) vs. taxable path with modeled drag and capital gains at exit.

Roth IRA Strategy 2026: Tax-Free Growth & Eligibility

Roth IRAs offer tax-free growth and withdrawals, making them powerful retirement vehicles. Use this to understand 2026 contribution limits, eligibility phase-outs, and the tax-free advantage over taxable accounts.

Strategic Roth IRA Insights

The Backdoor Roth Strategy: Bypassing Income Limits

High-income earners who exceed 2026 MAGI limits ($168,000 single / $252,000 joint) can still access Roth benefits via a 'Backdoor Roth' conversion.
Contribute to a Traditional IRA (no income limit), then immediately convert to Roth. This strategy requires careful tax planningโ€”you'll pay taxes on any pre-tax Traditional IRA balances. The calculator alerts you when your MAGI exceeds limits and suggests considering this strategy.

The Tax-Free Advantage: Compounding Without Tax Drag

Roth IRAs eliminate annual tax drag on dividends and capital gains taxes at withdrawal, allowing full compounding power.
While taxable accounts face 15-20% taxes on dividends annually and capital gains at sale, Roth IRAs compound tax-free. This compounding advantage grows exponentially over decadesโ€”the longer your time horizon, the greater the tax-free advantage. The calculator visualizes this difference.

The No RMD Freedom: Unlimited Tax-Free Compounding

Unlike Traditional IRAs, Roth accounts have no Required Minimum Distributions (RMDs) during your lifetime.
This allows unlimited tax-free compounding and flexible withdrawal timing. You can leave funds in a Roth IRA indefinitely, making it ideal for legacy planning. A $1M Roth IRA can grow to $2M+ over 20 years with no forced distributions, while a Traditional IRA would require RMDs starting at age 73.

The Phase-Out Trap: The Gradual Contribution Reduction

2026 phase-out ranges create a 'contribution cliff' where high earners lose access to Roth benefits gradually.
The phase-out mechanism reduces contributions dollar-for-dollar as MAGI increases within the range. This creates a strategic decision point: should you reduce income (via 401(k) contributions, HSA contributions) to stay below the phase-out range, or accept reduced Roth contributions? The calculator shows your exact reduced limit.

The 5-Year Rule: The Withdrawal Qualification Clock

The 5-year rule creates a 'qualification clock' that starts on January 1 of the year you make your first Roth IRA contribution.
This clock applies separately to each Roth IRA account. Contributions can be withdrawn tax-free immediately, but earnings must wait 5 years AND until age 59ยฝ. Understanding this clock helps you plan when to start Roth contributions to ensure earnings are qualified by retirement age.

The Catch-Up Advantage: $1,100 Extra for Age 50+

2026 catch-up contribution allows those 50+ to contribute an additional $1,100, raising the limit from $7,500 to $8,600.
This catch-up provision helps older savers accelerate retirement savings. Over 15 years, the extra $1,100/year at 7% return adds $30,000+ to your Roth IRA. The calculator automatically applies the catch-up limit if you're 50 or older.

The Tax Diversification Strategy: Creating Withdrawal Flexibility

Roth IRAs create tax diversification by providing a pool of tax-free retirement income that doesn't increase taxable income.
This flexibility allows strategic withdrawal sequencing: use Traditional IRA withdrawals to fill lower tax brackets (10-12%), then switch to Roth withdrawals for tax-free income. This 'bracket filling' strategy minimizes lifetime taxes and provides flexibility for unexpected expenses or tax law changes.

The Legacy Planning Advantage: Inherited Roth IRAs

Inherited Roth IRAs are tax-free to beneficiaries, while inherited Traditional IRAs are taxed at beneficiary rates.
Under the 10-year rule, a $500,000 inherited Traditional IRA requires $50,000/year distributions taxed at 22-24%, costing $11,000-$12,000/year in taxes. The same $500,000 inherited Roth IRA is completely tax-free, creating a $100,000-$150,000 legacy advantage over 10 years.

Understanding Roth IRAs: Tax-Free Growth and Withdrawals

What is a Roth IRA?

A Roth IRA is a retirement account that offers tax-free growth and tax-free withdrawals in retirement. Unlike Traditional IRAs, you contribute after-tax dollars (no immediate tax deduction), but all qualified withdrawals are 100% tax-free. This makes Roth IRAs ideal for those who expect to be in the same or higher tax bracket in retirement.

2026 Roth IRA Contribution Limits

2026 Roth IRA limits: $7,500 annual contribution for those under 50, $8,600 for those 50+ (includes $1,100 catch-up contribution). These limits apply to combined Traditional and Roth IRA contributions. For example, if you contribute $3,000 to a Traditional IRA, you can only contribute $4,500 to a Roth IRA (total $7,500). The calculator automatically applies the correct limit based on your age.

The Tax-Free Advantage

Roth IRAs eliminate taxes on withdrawals, while taxable accounts face capital gains taxes (15-20%) and annual tax drag on dividends. Over 30+ years, a $7,500/year Roth contribution at 7% return grows to $1.1M tax-free, while the same in a taxable account (after capital gains taxes) is worth $900K. The $200K difference represents the tax-free advantage. The calculator shows your exact tax savings.

2026 Eligibility and Phase-Out Ranges

2026 Income Limits (MAGI Phase-Out Ranges)

2026 Roth IRA income limits: Single filers: $153,000-$168,000 MAGI (phase-out range). Married filing jointly: $242,000-$252,000 MAGI (phase-out range). If your MAGI is below the phase-out range, you can contribute the full amount. Within the range, your contribution is reduced proportionally. Above the range, you're not eligible for direct contributions but may use a Backdoor Roth conversion.

How Phase-Out Works

If your MAGI falls within the phase-out range, your contribution limit is reduced proportionally. For example, if you're single with $160,000 MAGI (middle of $153K-$168K range), your $7,500 limit is reduced to $3,750. The calculator automatically calculates your reduced contribution limit based on your exact MAGI and alerts you when you're in the phase-out range.

Modified Adjusted Gross Income (MAGI)

MAGI for Roth IRA purposes = Adjusted Gross Income (AGI) + certain deductions added back (student loan interest, tuition, IRA contributions). Your MAGI determines your eligibility and contribution limits. The calculator uses your MAGI to check eligibility and calculate your maximum allowed contribution for 2026.

The Backdoor Roth Strategy

What is a Backdoor Roth?

A Backdoor Roth IRA is a strategy for high-income earners who exceed Roth IRA income limits. You contribute to a Traditional IRA (no income limit for contributions, though deductibility may be limited), then immediately convert it to a Roth IRA. This allows you to bypass income restrictions and access Roth benefits. The calculator alerts you if your MAGI exceeds 2026 limits and suggests considering this strategy.

How to Execute a Backdoor Roth

Step 1: Contribute to a Traditional IRA (no income limit for contributions). Step 2: Convert the Traditional IRA to a Roth IRA (no income limit for conversions). Step 3: Pay taxes on any pre-tax amounts converted. Important: If you have existing pre-tax Traditional IRA balances, the conversion may be partially taxable due to the 'pro-rata rule.' Consult a tax advisor for implementation.

Backdoor Roth Considerations

The Backdoor Roth strategy works best if you have no existing pre-tax Traditional IRA balances. If you have pre-tax balances, the conversion may be partially taxable. Some employers allow 'reverse rollovers' to move 401(k) funds to IRAs, which can complicate Backdoor Roth conversions. The calculator alerts you when your MAGI exceeds limits, but always consult a tax advisor before executing a Backdoor Roth.

Roth IRA vs. Taxable Account: The Tax-Free Advantage

Tax Drag on Taxable Accounts

Taxable accounts face annual tax drag: dividends are taxed at 15-20% (qualified dividends), and capital gains are taxed at 15-20% when realized. This tax drag reduces compounding over time. A $7,500/year investment at 7% return in a taxable account may only achieve 6.5% after-tax return due to annual tax drag on dividends and rebalancing.

Capital Gains Taxes at Withdrawal

Taxable accounts face capital gains taxes (15-20%) on growth when you sell investments. A $1M taxable account with $300K in gains would owe $45K-$60K in capital gains taxes. Roth IRAs have zero taxes on qualified withdrawals, preserving the full account value. The calculator shows the exact tax savings by comparing Roth (tax-free) vs. taxable (after capital gains taxes) account values.

The Lifetime Tax Savings

Over 30+ years, a Roth IRA can save $100,000-$500,000 in taxes compared to a taxable account, depending on contribution amounts, returns, and tax rates. The calculator projects your exact tax savings by comparing Roth (tax-free) vs. taxable (after capital gains taxes) account values at retirement. This shows the true value of tax-free growth.

No RMD Freedom: Unlimited Tax-Free Compounding

Traditional IRA RMDs

Traditional IRAs require Required Minimum Distributions (RMDs) starting at age 73 (2026 rules). RMDs force you to withdraw and pay taxes on a portion of your account each year, even if you don't need the money. This reduces tax-free compounding and can push you into higher tax brackets.

Roth IRA No RMD Advantage

Roth IRAs have no RMDs during the owner's lifetime, allowing unlimited tax-free compounding and flexible withdrawal timing. You can leave funds in a Roth IRA indefinitely, making it ideal for legacy planning. A $1M Roth IRA can grow to $2M+ over 20 years with no forced distributions, while a Traditional IRA would require RMDs starting at age 73.

Legacy Planning Benefits

The no-RMD feature makes Roth IRAs ideal for legacy planning. You can pass a larger, tax-free account to heirs. Inherited Roth IRAs are tax-free to beneficiaries (though subject to the 10-year distribution rule for non-spouse beneficiaries). This creates significant legacy value compared to Traditional IRAs, which are taxed at beneficiary rates.

The 5-Year Rule and Age 59ยฝ Requirements

Qualified Withdrawals

Earnings can be withdrawn tax-free if: (1) the account is at least 5 years old, and (2) you're age 59ยฝ or older. Contributions (not earnings) can be withdrawn tax-free at any time, regardless of age or account age. The 5-year clock starts on January 1 of the year you make your first Roth IRA contribution.

Early Withdrawal Penalties

Early withdrawals of earnings (before age 59ยฝ or before 5 years) may be subject to income tax and a 10% penalty. However, there are exceptions: first-time home purchase (up to $10,000), qualified education expenses, disability, or death. The calculator reminds you of the 5-year rule to help plan withdrawal timing.

Planning Withdrawal Timing

The 5-year rule means you should start Roth IRA contributions early to ensure earnings are qualified by retirement age. If you're 55 and start a Roth IRA, you'll be 60 (over 59ยฝ) when the 5-year requirement is met. The calculator helps you understand when your withdrawals will be fully tax-free.

Roth IRA vs. Traditional IRA: Which to Choose?

Choose Roth IRA If

Your current tax rate is lower than expected future rate, you want tax-free withdrawals, you want no RMDs, you're young with many years for tax-free growth, or you want tax diversification. Roth IRAs are ideal for young professionals who expect higher income in retirement and want to lock in current tax rates.

Choose Traditional IRA If

Your current tax rate is higher than expected future rate, you want immediate tax deduction, you need to reduce current taxable income, or you're in a high tax bracket now. Traditional IRAs provide immediate tax savings but require RMDs and taxes on withdrawals. The calculator helps you see the tax-free advantage of Roth contributions.

Tax Diversification Strategy

Having both Roth and Traditional IRAs provides tax diversification. In retirement, withdraw from Traditional IRAs to fill lower tax brackets, then use Roth withdrawals for tax-free income. This strategy minimizes lifetime taxes and provides flexibility. The calculator helps you understand the tax-free advantage of Roth contributions for your situation.

FAQ

What are the 2026 Roth IRA contribution limits?

2026 Roth IRA limits: $7,500 annual contribution for those under 50, $8,600 for those 50+ (includes $1,100 catch-up contribution). These limits apply to combined Traditional and Roth IRA contributions. The calculator automatically applies the correct limit based on your age and checks eligibility based on your Modified Adjusted Gross Income (MAGI).

What is the 2026 Roth IRA income limit?

2026 Roth IRA income limits (phase-out ranges): Single filers: $153,000-$168,000 MAGI. Married filing jointly: $242,000-$252,000 MAGI. If your MAGI is below the phase-out range, you can contribute the full amount. Within the range, your contribution is reduced proportionally. Above the range, you're not eligible for direct contributions but may use a Backdoor Roth conversion.

What is a Backdoor Roth IRA?

A Backdoor Roth IRA is a strategy for high-income earners who exceed Roth IRA income limits. You contribute to a Traditional IRA (no income limit), then immediately convert it to a Roth IRA. This allows you to bypass income restrictions. The calculator alerts you if your MAGI exceeds 2026 limits and suggests considering a Backdoor Roth conversion. Consult a tax advisor for implementation.

How does a Roth IRA compare to a taxable account?

Roth IRAs offer tax-free growth and withdrawals, while taxable accounts face capital gains taxes (15-20%) and annual tax drag on dividends. Over 30+ years, a Roth IRA can save $100,000-$500,000 in taxes compared to a taxable account. The calculator shows the exact tax savings by comparing Roth (tax-free) vs. taxable (after capital gains taxes) account values at retirement.

Do Roth IRAs have Required Minimum Distributions (RMDs)?

No, Roth IRAs have no RMDs during the owner's lifetime, unlike Traditional IRAs. This allows unlimited tax-free compounding and flexible withdrawal timing. You can leave funds in a Roth IRA indefinitely, making it ideal for legacy planning and tax diversification. RMDs only apply to inherited Roth IRAs (10-year rule for non-spouse beneficiaries).

What is the 5-year rule for Roth IRAs?

The 5-year rule requires that earnings remain in a Roth IRA for 5 years and until age 59ยฝ for withdrawals to be fully tax-free. Contributions (not earnings) can be withdrawn tax-free at any time. Early withdrawals of earnings may be subject to income tax and a 10% penalty. The calculator reminds you of this rule to help plan withdrawal timing.

Should I choose a Roth IRA or Traditional IRA?

Choose Roth IRA if: your current tax rate is lower than expected future rate, you want tax-free withdrawals, you want no RMDs, or you're young with many years for tax-free growth. Choose Traditional IRA if: your current tax rate is higher than expected future rate, you want immediate tax deduction, or you need to reduce current taxable income. The calculator helps you see the tax-free advantage of Roth IRAs.

Can I contribute to both a Roth IRA and Traditional IRA?

Yes, but the combined contribution limit applies. For 2026: $7,500 total (or $8,600 if 50+) across both Roth and Traditional IRAs. For example, you could contribute $3,000 to Traditional and $4,500 to Roth, totaling $7,500. The calculator shows your maximum Roth contribution based on 2026 limits and your MAGI.

How much can I withdraw tax-free from a Roth IRA?

Contributions can be withdrawn tax-free at any time. Earnings can be withdrawn tax-free if: (1) the account is at least 5 years old, and (2) you're age 59ยฝ or older. The calculator shows your projected monthly tax-free income at retirement using a 4% safe withdrawal rate. All qualified withdrawals are 100% tax-free.

What happens if I contribute too much to a Roth IRA?

Excess contributions are subject to a 6% penalty per year until corrected. You can avoid the penalty by withdrawing the excess (and earnings) before the tax filing deadline, or by applying the excess to the next year's contribution limit. The calculator helps you stay within 2026 limits by showing your maximum allowed contribution based on age and MAGI.
