What Is Dollar-Cost Averaging?
Quick answer: Dollar-cost averaging means investing a fixed amount on a regular schedule, regardless of market movements.
Understand the core concept
A fixed amount buys more shares when the price is lower and fewer shares when the price is higher, assuming fractional shares or available purchase quantities.
See how it works
It can provide an investment routine and reduce the pressure to select a single entry point. It does not guarantee gains or prevent loss in a falling market.
Know the limitations
Investing available cash immediately and spreading purchases over time are different decisions with different risk exposures. Outcomes depend on the period and market path.
Put it into context
Consider fees, account limitations, expected cash needs and overall asset allocation before adopting any automated investment routine.
Try this yourself
Use a fictional three-month price series to calculate how many shares $100 might buy each month.
