Initial balance, total contributions, and massive tax-free earnings wedge
Final account value at retirement: Roth (tax-free) vs. Taxable (after capital gains taxes)
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.
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.
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 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.
Where:
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 $1,234,567.
The calculator automatically checks your Modified Adjusted Gross Income (MAGI) against 2026 IRS phase-out limits to determine your maximum allowed contribution.
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.
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.
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.
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
Where t = Annual Tax Drag Rate (0.5% for 2026)
Step 2: Calculate Future Value with Reduced Return
Step 3: Apply Capital Gains Tax at Withdrawal
Where Growth = Taxable Future Value - Total Contributions
Where:
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.
The 2026 Roth IRA calculation process involves three key steps:
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 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.
