Here's How Big a $50,000 Investment in the S&P 500 Could Get in 25 Years

The article is a long-term investing explainer about the S&P 500 and the Vanguard S&P 500 ETF (VOO). It notes that the index has historically returned about 10% annually, but cautions future returns could be lower after recent strong market performance. Using a $50,000 hypothetical investment, the piece shows how a 1 percentage point difference in annual return matters dramatically over 25 years: about $541,735 at 10% versus $431,154 at 9%, a gap of roughly $110,000. The main market takeaway is that even small changes in expected compound returns can have a large impact on long-term wealth accumulation, reinforcing the appeal of low-cost broad-market index funds as relatively low-risk, diversified vehicles for patient investors.
