How is average cost calculated?
Your average entry price is total money invested ÷ total units bought. Each buy contributes units equal to its amount ÷ its price, so larger buys and cheaper buys pull your average more. This is your cost basis — the price the market has to beat for you to be in profit.
What is DCA (dollar-cost averaging)?
DCA means buying a fixed amount at regular intervals regardless of price. It smooths out your entry so you're not trying to time the exact bottom. Add each of your recurring buys here and you'll see the blended average price it produced.
Does this work for stocks too?
Yes — the math is identical for any asset. Enter the share price and dollar amount of each purchase to get your average cost per share, total invested and current value.
Should I average down on a losing trade?
Sometimes, but it's one of the fastest ways to turn a small loss into a large one if the trend keeps going against you. Decide it in advance as part of a plan, size it against your total risk (see our position size calculator), and let a tool like TradeX Pro confirm the setup rather than buying on hope.
