How Dollar-Cost Averaging (DCA) Helps

If you’ve ever worried about investing your money at the “wrong” time, you’re not alone. Markets go up, markets go down - and trying to perfectly time them is nearly impossible. That’s where Dollar-Cost Averaging (DCA) comes in. Instead of investing a lump sum all at once, you spread it out over time.

An Example

Let’s say you invest $100 every month into Apple Inc stock for five months. During that time, the stock price changes:

Month Price Amount Invested Shares Bought
1 $100 $100 1.00
2 $80 $100 1.25
3 $125 $100 0.80
4 $90 $100 1.11
5 $105 $100 0.95
Total $500 5.11

Because you invest the same $100 each month:

  • You buy more shares when the price is low

  • You buy fewer shares when the price is high

After five months, you’ve invested $500 total. Because you bought more shares during the dips, your average cost per share ($97.80) ends up lower than the average stock price over that period ($100). The portfolio is now worth $536.55 (5.11 x $105).
