Dollar-Cost Averaging
Dollar-cost averaging means investing a fixed amount on a regular schedule, regardless of price, instead of trying to time the market.
Dollar-cost averaging means investing a fixed amount on a regular schedule, regardless of price.
Why it matters
Prices move constantly, and trying to invest at the perfect moment is difficult even for professionals. Putting in the same amount on a regular schedule removes that pressure.
When prices are higher your fixed amount goes less far, and when prices are lower it goes further. Over time this can smooth out the average price you pay and reduce the role of emotion.
Simple example
Suppose you invest $100 every month. In a month when the price is $50, your $100 gets you two units. In a month when the price falls to $25, the same $100 gets you four units. Across many months you end up with a blended average price rather than betting everything on one moment. This does not promise a profit, and it will not beat a perfectly timed lump sum, but it is a calm, repeatable approach.
Common mistakes
- Stopping the schedule during downturns, which is often when the fixed amount goes furthest.
- Thinking dollar-cost averaging promises a gain. It is a method, not a guarantee.
- Comparing it only to a perfectly timed lump sum, which is unknowable in advance.
- Letting fees on frequent small purchases eat into the benefit.
How to think about it
Practical pointers for learning, not advice to buy or sell anything.
