The Backdoor Roth Strategy

If your MAGI exceeds 2026 limits ($168,000 single / $252,000 joint), you can still contribute to a Roth via a "Backdoor Roth" conversion: contribute to a Traditional IRA (no income limit), then convert to Roth. This strategy requires careful tax planning.

๐Ÿ’ธ

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, this tax-free compounding can save $100,000-$500,000 compared to taxable accounts.

No RMD Freedom

Unlike Traditional IRAs, Roth accounts have no Required Minimum Distributions (RMDs) during your lifetime. This allows unlimited tax-free compounding and flexible withdrawal timing, making Roth IRAs ideal for legacy planning and tax diversification.

The Science of Your Savings

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 + C * [((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 Engine

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-Out Reduction = Max Contribution * [((MAGI - Phase-Out Min) / (Phase-Out Max - Phase-Out Min))]

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-Free Advantage: Calculating Tax Drag

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

Taxable Return Rate = r * (1 - t/100)

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

Step 2: Calculate Future Value with Reduced Return

Taxable Future Value = P(1 + rtaxable)^n + C * [((1 + rtaxable)^n - 1) / rtaxable]

Step 3: Apply Capital Gains Tax at Withdrawal

Taxable Account Value = Taxable Future Value - (Growth * 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% * (1 - 0.5/100) = 6.965%. 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 is a Roth IRA calculated in 2026?

The 2026 Roth IRA calculation process involves three key steps:

  1. Eligibility Check: Verify your MAGI against 2026 phase-out limits ($153k-$168k for singles, $242k-$252k for joint filers) to determine your maximum allowed contribution.
  2. Future Value Projection: Apply the Future Value of an Annuity formula using your starting balance, annual contributions, expected return rate, and years until retirement.
  3. Tax Savings Comparison: Calculate the difference between Roth growth (tax-free) and equivalent taxable account growth (with tax drag) to quantify the long-term tax advantage.

The calculator automatically performs all three calculations in real-time as you adjust your inputs, providing instant feedback on your retirement savings trajectory and tax savings potential.

Roth IRA Strategy 2026: Tax-Free Growth & Eligibility

Roth IRAs offer tax-free growth and withdrawals, making them powerful retirement vehicles. This calculator helps you 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

โ€ขHigh-income earners who exceed 2026 MAGI limits ($168,000 single / $252,000 joint) can still access Roth benefits via a 'Backdoor Roth' conversion.
โ€ขContribute 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

โ€ขRoth IRAs eliminate annual tax drag on dividends and capital gains taxes at withdrawal, allowing full compounding power.
โ€ขWhile 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

โ€ขUnlike Traditional IRAs, Roth accounts have no Required Minimum Distributions (RMDs) during your lifetime.
โ€ขThis 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

โ€ข2026 phase-out ranges create a 'contribution cliff' where high earners lose access to Roth benefits gradually.
โ€ขThe 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

โ€ขThe 5-year rule creates a 'qualification clock' that starts on January 1 of the year you make your first Roth IRA contribution.
โ€ขThis 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+

โ€ข2026 catch-up contribution allows those 50+ to contribute an additional $1,100, raising the limit from $7,500 to $8,600.
โ€ขThis 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

โ€ขRoth IRAs create tax diversification by providing a pool of tax-free retirement income that doesn't increase taxable income.
โ€ขThis 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

โ€ขInherited Roth IRAs are tax-free to beneficiaries, while inherited Traditional IRAs are taxed at beneficiary rates.
โ€ขUnder 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.
