What Is a Roth IRA? The Single Best Account for Young Investors
By Pennie at FiscallyAI • Updated • 12 min read
How a Roth IRA Works
You contribute money that has already been taxed (after-tax dollars). Your investments grow tax-free. When you withdraw in retirement, you pay zero taxes on the gains.
Why This Is Incredible for Young People
If you invest $6,500/year from age 25 to 65 at a 10% average return, you will have approximately $3.5 million. You contributed $260,000 total. The remaining $3.24 million in growth is completely tax-free.
In a traditional (pre-tax) account, you would owe income tax on every dollar you withdraw. At a 22% tax bracket, that is $715,000 in taxes. A Roth IRA saves you that entire amount.

Key Rules
- Contribution limit (2026): $7,000/year ($8,000 if over 50).
- Income limit: You cannot contribute directly if you earn over $161,000 (single) or $240,000 (married). Backdoor Roth conversions exist for higher earners.
- Withdrawal of contributions: You can withdraw your contributions (not gains) at any time, for any reason, with no penalty. This makes it a dual-purpose emergency fund and retirement account.
- Withdrawal of gains: Tax-free and penalty-free after age 59.5, provided the account has been open for at least 5 years.

Roth IRA vs. Traditional IRA
| Feature | Roth IRA | Traditional IRA |
|---|---|---|
| Tax on contributions | Pay now | Deduct now |
| Tax on withdrawals | Tax-free | Taxed as income |
| Best if your tax rate will be | Higher in retirement | Lower in retirement |
| Required Minimum Distributions | None | Starting at 73 |
For most young people, a Roth IRA is the clear winner because your income (and tax rate) is likely to be higher in the future than it is now.
