$150 a month in Vanguard’s S&P 500 ETF could reach roughly $300,000 in 30 years, based on a modest 10% annual return, though actual results depend on future performance.
The Vanguard S&P 500 ETF (VOO) began trading in September 2010 and has posted average annual returns of 19.6% over three years, 11.4% over five years, 13.6% over ten years, and 12.8% since inception, according to YCharts data.
Using a $150 monthly contribution, the article’s calculations show that if VOO sustained its 19.6% three‑year average for 30 years the investment would total about $1.96 million; at the 11.4% five‑year average it would reach roughly $386,800; at the 13.6% ten‑year average about $593,600; and at the 12.8% since‑inception average about $507,500. A more modest 10% assumed return would still grow the contributions to over $296,000, not including VOO’s 0.03% expense ratio.
VOO mirrors the S&P 500, giving investors exposure to roughly 505 large‑cap U.S. companies across all major sectors. It is market‑cap weighted, low‑cost, and offers diversification and blue‑chip exposure in a single fund.
The article notes that future performance cannot be predicted; assuming past averages over a 30‑year horizon may be overly optimistic, so actual outcomes will depend on how VOO performs going forward.
