How Roth IRA Growth Works
A Roth IRA grows through compound investment returns. Unlike a Traditional IRA, all growth and withdrawals in retirement are 100% tax-free. Contributing $6,000/year starting at age 30 at a 7% average return results in approximately $887,000 by age 65 — and you owe zero taxes on it.
The key insight: the longer your money compounds, the more powerful the effect. Someone who starts at 25 will have roughly twice as much as someone who starts at 35, even contributing the same annual amount.

Most financial advisors recommend low-cost index funds (S&P 500 index fund or total market fund) for long-term Roth IRA growth. The historical average S&P 500 return is ~10%/year before inflation. Target-date funds are another popular hands-off option.
