❓ FAQ
Can I really start with just $100?
Yes. Fidelity, Schwab, and Robinhood let you buy fractional shares with as little as $1. No minimum to open an account.
Is $100 enough to make a difference?
$100/month invested from age 25 to 65 at 7% = $262,000. Small amounts compound into big numbers given enough time.
Should I invest or pay off debt first?
If debt APR > 7%, pay it off first. If debt APR < 5%, invest while making minimum payments. If it's a mortgage at 3-4%, definitely invest.
What about crypto?
No more than 5% of your portfolio. Bitcoin/ETH are extremely volatile. Index funds should be your core.
