What is Dollar-Cost Averaging in Investment?

Last Updated on June 5, 2023

Dollar-cost averaging is an investment strategy where a fixed amount of an investment is purchased regardless of market price. This strategy allows investors to mitigate the risk of investing all at once and manage volatility by spreading investments over time. More shares are bought when prices are low, and fewer when high.

Dollar-cost averaging has been a valuable tool in stock market investing, tempering the unpredictability and wild price fluctuations. It’s believed to have gained popularity during the Great Depression in the 1930s. Amid economic uncertainty, investors were reluctant to invest. However, regular small investments via dollar-cost averaging promised potential long-term gains.

What Is Dollar-Cost Averaging in Investment?

Today, dollar-cost averaging remains popular among both novices and seasoned investors. It’s useful for those keen to invest in stocks but are unsure about timing or don’t want to buy all shares at once.

Basically, dollar-cost averaging is a simple yet effective investment strategy that can gradually build wealth and manage risks. By investing fixed amounts at regular intervals, investors can utilize market volatility without massive exposure. While not a guaranteed profit-making strategy, it’s an essential tool for those seeking to grow wealth while minimizing risks.

How Dollar-Cost Averaging Works

Dollar-Cost Averaging (DCA) is a simple yet effective investment strategy that involves investing a fixed amount of money at set intervals. It is a long-term strategy that enables investors to buy more shares when prices are low and fewer shares when prices are high, helping to spread out risk and potentially reduce losses. Below we explain in detail how dollar-cost averaging works, the benefits of using this investment strategy, and some examples of how it works in practice.

Dollar-cost averaging is an investment strategy that involves investing a fixed amount of money into a mutual fund or other investment vehicle at regular intervals, such as monthly or quarterly. The idea behind DCA is to buy more when prices are low and less when prices are high.

For example, if an investor decides to invest $100 per month into a mutual fund, they will purchase more shares when the price is low and fewer shares when the price is high. This means that over time, the investor will have purchased more shares at a lower cost and fewer shares at a higher cost.

Explanation of the Investment Strategy

The underlying principle of dollar-cost averaging is to help reduce the risk of volatile swings in the market. By investing a fixed amount of money at regular intervals, investors are able to purchase more shares when prices are low, and fewer shares when prices are high.

This helps to reduce the impact of market volatility and minimize the risk of purchasing all shares at once when prices are high. DCA enables investors to build their portfolio gradually, allowing them to ride out short-term market fluctuations without making quick and emotional decisions.

Benefits of Using Dollar-Cost Averaging

Dollar-cost averaging helps to remove emotions from the investment process by allowing investors to develop a disciplined approach to investing that positions them for the long term. Here are some of the primary benefits of using this investment strategy:

  1. Reduced market risk: DCA helps investors avoid the risk of buying all shares at once when prices are high, minimizing the potential losses from market volatility.

  2. Reduced stress and anxiety: By investing small amounts at regular intervals, investors can avoid the stress and anxiety of trying to time the market.

  3. Systematic approach: DCA helps investors develop a disciplined and systematic approach to investing that can help achieve long-term financial goals.

  4. Potential higher returns: Since DCA involves investing in the market over an extended period, investors may potentially earn higher returns than those who try to time the market.

Examples of How It Works in Practice

To help illustrate how dollar-cost averaging works in practice, let’s consider the following examples:

Example 1: An investor decides to invest $500 in a mutual fund and purchases all the shares at once. The mutual fund is initially priced at $50 per share, so the investor buys 10 shares.

Unfortunately, the market drops significantly, and the value of the mutual fund decreases to $25 per share. The investor now feels trapped in a bad investment and decides to sell the shares, losing half of their initial investment.

Example 2: Another investor decides to invest $500 in the same mutual fund but decides to use DCA instead. They invest $100 per month for five months, purchasing a varying amount of shares based on the monthly price.

If the price is $50, they purchase two shares. If the price is $25, they purchase four shares. After five months, the investor has purchased a total of 13 shares and has an average cost of $38.46 per share, which is significantly lower than the initial price of $50 per share.


Dollar-cost averaging is a simple yet effective investment strategy that can offer significant benefits for long-term investors. By investing a fixed amount of money at regular intervals, investors can potentially reduce market risk, minimize stress and anxiety, develop a systematic approach to investing, and potentially earn higher returns. Remember, an investor who uses DCA is positioning themselves for the long-term, not the short term.
