Dollar-cost averaging invests a fixed amount at regular intervals regardless of price. Over long periods, you automatically buy more shares when prices are low and fewer when high. Even a 1% expense ratio difference can cost $50,000–$100,000 over 30 years — always check the expense ratio before investing.
