dollar-cost averaging

An investment strategy of buying a fixed dollar amount of an asset at regular intervals regardless of the price, reducing the impact of volatility.

Example

“By investing $500 in index funds every month regardless of the market, she practiced dollar-cost averaging.”

Memory Tip

DCA = same DOLLAR amount, every time — smoothing out price swings.

Why It Matters

Dollar-cost averaging helps reduce the stress of timing the market perfectly, which is nearly impossible for most investors. By investing consistently over time, you can build wealth steadily while minimizing the risk of investing a large sum right before a market downturn.

Common Misconception

Many people believe dollar-cost averaging guarantees profits or eliminates all investment risk entirely. In reality, it only reduces the impact of volatility and does not protect you from losses if the overall market declines over your investment period.

In Practice

Suppose you invest $500 monthly in a stock fund over six months when prices fluctuate significantly. In month one at $50 per share you buy 10 shares, month two at $40 you buy 12.5 shares, month three at $60 you buy 8.3 shares, and so on. Your average cost per share becomes lower than if you had tried to time the perfect entry point, smoothing out the impact of price swings.

Etymology

Plain English: averaging the cost by investing consistent dollar amounts over time.
