Question 1

What is dollar-cost averaging?

Accepted Answer

Dollar-cost averaging (DCA) is an investment strategy where you invest a fixed amount of money at regular intervals — for example, every month — regardless of whether prices are high or low. Over time this tends to produce a lower average cost per share than trying to time the market.

Question 2

Why does this calculator use a linear price path?

Accepted Answer

A linear price path — a straight line from the start price to the end price — is the simplest way to illustrate the DCA effect without requiring real market data. It clearly shows how buying more shares when prices are low and fewer when prices are high naturally lowers your average cost.

Question 3

Is DCA better than investing a lump sum all at once?

Accepted Answer

Historically, lump-sum investing tends to produce slightly higher returns because markets trend upward over time. However, DCA reduces the risk of investing everything at a market peak and is psychologically easier for most people, especially beginners.

Question 4

Does this calculator account for dividends or fees?

Accepted Answer

No. This calculator focuses purely on the mechanics of buying shares at different prices over time. Dividends, brokerage commissions, and taxes are not included. For fee impact, try the Fees Drag Calculator when it becomes available.

Question 5

Can I use DCA with ETFs or individual stocks?

Accepted Answer

Yes. DCA works with any asset you can buy in fractional or whole units at regular intervals — ETFs, index funds, individual stocks, or even government bonds sold on a secondary market.
