Dollar-cost averaging means investing the same amount at regular intervals, regardless of price. You buy more shares when prices are low and fewer when high.
How it works
If you invest $500 per month, a month with a lower share price buys more shares. Over time your average cost per share tends to be smoother than the average price. Anyone contributing to a 401(k) from each paycheck is already doing this.
DCA vs lump sum
Since markets rise more often than they fall, historically investing a lump sum immediately has beaten spreading it out around two-thirds of the time. DCA lowers the risk of investing everything right before a drop and can ease anxiety.
When to use it
Use DCA when your money arrives over time, as with paychecks, or when you would otherwise stay in cash due to fear. Choose a schedule, automate it and stick with it through volatility.
Try the numbers
Use our Dollar-Cost Averaging Calculator to see this in practice. With its default example (Monthly investment: $500; Years: 10; Expected annual return: 7%), it shows dca ending value: $86,542. Adjust the inputs to match your situation.
Key takeaways
- DCA invests fixed amounts on a schedule.
- Lump sums have historically done better more often.
- Automation removes emotion from investing.
