This Stock Average Calculator helps investors calculate their average cost per share after multiple purchases at different prices. It is essential for tracking your cost basis and making informed decisions about averaging down or taking profits.
Whether you practice dollar-cost averaging (DCA), buy the dip, or simply accumulate shares over time, knowing your average entry price is critical for portfolio management.
Average cost per share is the total amount invested divided by the total number of shares purchased. It represents your blended entry price across multiple trades.
Average down means buying more shares at a lower price than your original purchase. This reduces your average cost per share. Enter all your purchases (including the new lower-price buy) into this calculator to see your new average.
DCA is an investment strategy where you buy a fixed dollar amount of an asset at regular intervals, regardless of price. This calculator helps you track your average entry price across all DCA purchases.
