Absolutely. While 30 years gives you the full power of compounding, even 10 years of consistent investing produces impressive results. $500/month at 8% for 10 years turns $60,000 into about $91,000 — a 50% gain. At 15 years, that becomes $173,000 from $90,000 invested. The key is starting now and staying consistent. Every year you wait shrinks the window.
