Building a $100,000 investment portfolio is achievable through consistent monthly contributions and long-term discipline. Depending on your time horizon, you need to invest $490/month over 10 years, $130/month over 20 years, or just $45/month over 30 years, assuming a historical 10% average annual S&P 500 return. The key is maintaining investments through market volatility and letting compound growth do the heavy lifting over time.
Axe note: Steady monthly investing, even in modest amounts, can build substantial wealth if held long enough.
