Roth IRA Retirement Output
Quick Summary
Our roth ira calculator tax free growth limits projects your total Roth IRA wealth at retirement, tax-free compound investment growth, and capital gains tax savings. By accounting for post-tax annual contributions, 2026 IRS contribution limits ($7,000 / $8,000 catch-up), and income phase-out thresholds, this calculator reveals the extraordinary wealth-building power of 100% tax-free retirement growth.
How It Works: Post-Tax Dollars, Tax-Free Growth & Income Phase-Outs
A Roth IRA is an Individual Retirement Account funded with post-tax dollars (income you've already paid taxes on). In exchange, your money grows completely tax-free, and all qualified withdrawals after age **59½** (and a 5-year holding period) are **100% TAX-FREE**. For 2026, the maximum contribution limit is **$7,000** for individuals under age 50 and **$8,000** for those age 50 or older. High earners are subject to IRS income phase-out rules ($146k-$161k Single / $230k-$240k Married Jointly).
Formula Explanation
Your allowable annual contribution ($Contrib_{allowed}$), future Roth IRA balance ($Balance_n$), and capital gains tax savings ($TaxSaved$) are calculated as follows:
Step-by-Step Worked Example
Here is a detailed 5-step breakdown for a 25-year-old investor starting with a $10,000 balance, contributing the maximum $7,000/year at an 8.0% annual investment return over 40 years (retiring at age 65):
- Step 1 (Calculate Total Out-of-Pocket Contributions): $\$10,000 \text{ starting} + (40 \times \$7,000) = \mathbf{\$290,000.00 \text{ total invested}}$.
- Step 2 (Simulate Multi-Decade Compound Growth): At 8.0% return over 40 years, total balance compounding reaches **$2,036,540.00**.
- Step 3 (Calculate 100% Tax-Free Investment Earnings): $\$2,036,540 - \$290,000 = \mathbf{\$1,746,540.00 \text{ in tax-free growth}}$!
- Step 4 (Calculate Tax Savings vs Taxable Account): A taxable brokerage account charging 15% long-term capital gains tax would owe $\$1,746,540 \times 15\% = \mathbf{\$261,981.00 \text{ in taxes}}$!
- Step 5 (Compute Net Advantage): In a Roth IRA, you keep 100% of the **$2,036,540.00 balance** with **$0 owed to the IRS**!

The 5-Year Rule requires your Roth IRA account to be open for at least 5 tax years before investment earnings can be withdrawn completely tax-free after age 59½.

No! Unlike 401(k)s or Traditional IRAs, original owners of Roth IRAs are NEVER required to take RMDs during their lifetime.
Is a Roth IRA better than a Traditional IRA?
A Roth IRA is better if you expect to be in a higher tax bracket in retirement or want tax-free growth. A Traditional IRA is better if you need upfront tax deductions today.
