Definition: To invest, as in shares of stock, fixed amounts of money at regular intervals so as to buy more at lower prices ad less at higher prices .
Dollar-cost averaging means that if you put the same amount in each year, you'll buy more investments, such as shares of a mutual fund, when prices are down and fewer when prices are up. The end result will be that you'll pay a lower average price than the actual average price of the investment during that period.
