Why Starting a Roth IRA Early Pays Off
A Roth IRA doesn't give you an upfront tax deduction like a traditional IRA — you contribute with money you've already paid income tax on. Its real advantage shows up later: every dollar of investment growth inside the account, and every qualified withdrawal in retirement, is completely tax-free. That's a huge deal if you start young, because the earlier your contributions begin compounding, the larger the share of your final balance that comes from tax-free growth rather than your original contributions. In a regular taxable brokerage account, that same growth would eventually be taxed as capital gains when you sell.
How the Estimate Works
| Step | What It Means |
|---|---|
| Eligibility | Full limit under $150,000 MAGI, phases out to $0 at $165,000 |
| 2025 limit | $7,000/year (under 50) |
| Tax savings | Investment gain × 15% (assumed long-term capital gains rate) |
This calculator compares your Roth IRA balance to what the same contributions would be worth in a taxable account after paying capital gains tax on the growth. The difference is the tax advantage of starting early. Keep in mind actual limits, phase-out ranges, and tax brackets can change year to year, and this tool assumes a constant return rate for simplicity — real markets fluctuate.
