What is Dollar Cost Averaging?


Dollar Cost Averaging or DCA is the technique of buying a fixed dollar amount of an investment on a regular schedule, irrespective of the price. The theory being that more shares are purchased when the price is low and fewer shares purchased when the price is high.

The most common examples of this are your 401k and 403b investment plans through your employer. Every paycheck you have a set amount set aside to purchase a predetermined investment at whatever price is currently being offered.

The most common vehicles for the use of this type of investment are mutual funds or ETF(exchange traded funds). Typically these are the choices offered in most employer retirement plans. The best option to look for in mutual funds is a no-load fund.


This means that there are no fees upfront for investing in the fund. In some cases, you can start with as little as $25 to invest. Which is great for folks just starting out or on a limited budget.

Some mutual funds will waive their minimums if you start an automatic investment plan. These are often available directly through the mutual funds website.

ETFs are also great for this strategy as well because of their no minimums to invest and typically ultra low fees they charge.

The idea behind all this is to try to give people the opportunity to take advantage of the power of compounding, which we discussed earlier.

  1. The stock market rises over time. One disadvantage of dollar cost averaging is that the market tends to go up over time. This means that if you invest a larger sum in the market earlier. It is very likely to do better over time than a smaller investment. The larger sum will produce a better return over time as the market continues to rise.
  2. It is not a good substitute for finding good investments. Dollar cost averaging is not the end all be all of investing. You still need to do your research and identify good investments. Because if you invest in a bad pick you will be steadily investing in an investment that will continue to lose money. It also does not allow for adapting to the environment in the market. Let’s say you uncover a pick that has potential based on news that its earnings will allow it to increase its value. Your strategy will not allow you getting into an investment with that particular company.
