Frequently Asked Questions
How does compound interest work?
Compound interest earns interest on your interest. If you invest $1,000 at 7% annually, after year 1 you have $1,070. Year 2 you earn 7% on $1,070 (not just the original $1,000). Over decades, this snowballs dramatically.
How much should I invest monthly to become a millionaire?
Investing $500/month at 7% annual return for 35 years gives you about $900,000. Increasing to $600/month gets you over $1 million. Start early — time is the most powerful factor in compound growth.
What's a realistic annual return to expect?
The S&P 500 has historically returned about 10% annually before inflation, or about 7% after inflation. Our calculator defaults to 7%. Conservative estimates use 5-6%; optimistic use 8-10%.
