Yahoo Finance, citing analysis from The Motley Fool, indicates that to fully replace the average U.S. annual salary of $65,000 with dividend income, investors would need to hold a substantial number of shares in dividend ETFs. Specifically, calculations show that investing in the Vanguard High Dividend Yield ETF (VYM) would require holding 17,905 shares, totaling approximately $2.95 million. For the Schwab U.S. Dividend Equity ETF (SCHD), 13,156 shares would be needed, amounting to about $2.17 million. SCHD requires 26.5% less capital than VYM due to its higher yield of 3% (compared to VYM's 2.2%).
