Absolutely. At a 7% average return, $500/month becomes over $260,000 in 20 years and over $600,000 in 30 years. Consistency is more important than the amount you start with.
For money you need within 1-3 years, use a high-yield savings account. For goals 5+ years away, investing typically provides better returns. Consider your risk tolerance and timeline.
The math scales proportionally. $300/month at 7% for 10 years gives you about $51,900. Every dollar counts.
The 7% figure we used is roughly the S&P 500's historical average after inflation. In nominal terms, actual returns have averaged about 10%. So these projections are already fairly conservative.
