Simulation assumes the price drifts in a straight line from your start price to your end price across all 12 buys. Real markets move unevenly, so treat this as an illustration.
How it works
Dollar-cost averaging means investing a fixed amount on a regular schedule regardless of price. Because each buy is the same dollar value, you automatically acquire more units when the price is low and fewer when it is high. This calculator drifts the price linearly from your start price to your end price across every period, buys your fixed amount at each step, and sums the units to find your blended average cost.
Total invested is simply your per-buy amount multiplied by the number of periods. Current value multiplies your accumulated units by the end price, and ROI compares that value against everything you invested.
FAQ
What is dollar-cost averaging?
It is a strategy of buying a fixed dollar amount at regular intervals to smooth out the impact of volatility, rather than trying to time a single entry.
How is the average cost calculated?
Average cost = total invested ÷ total units accumulated. It reflects the blended price you effectively paid across all of your buys.
Why does the price move in a straight line?
A linear drift keeps the simulation simple and transparent. Real prices fluctuate, so use this as an illustration of the averaging effect rather than a precise forecast.
