The Roth IRA, explained simply
A Roth IRA is one of the most powerful tools available to younger investors. You pay tax now, and the money grows (and comes out) tax-free.
How it works
You open a Roth IRA at a brokerage on your own (not through an employer). You contribute after-tax dollars up to the annual limit. Your investments grow tax-free, and qualified withdrawals in retirement are 100% tax-free.
Why it's special
Decades of compounded gains are never taxed. For someone starting in their 20s, that can mean tens of thousands of dollars more than the same money in a taxable account.
- Contributions (not earnings) can be withdrawn at any time, penalty-free
- No required minimum distributions in retirement
- Income limits apply. High earners may need a backdoor Roth
How to open one
Pick a brokerage (Fidelity, Vanguard, Schwab are the usual suspects). Open a Roth IRA. Fund it from your bank. Most people invest in a target-date fund or a simple three-fund portfolio.
What does tax-free compounding actually look like?
A Roth IRA's real magic is decades of growth that's never taxed. Try different contributions and time horizons to see the curve.
