What is DCA Calculator?
A DCA (Dollar-Cost Averaging) calculator evaluates the outcome of investing a fixed amount at regular intervals across a series of prices. It divides each contribution by the prevailing price to determine units bought, then aggregates total invested, average cost per unit, total units held, and the final portfolio value at the last price. The result is a clear picture of how disciplined periodic investing performs through volatility.
