What the calculation measures
Dollar-cost averaging changes the number of shares bought as price changes. It does not guarantee a profit or a better return than lump-sum investing.
How to interpret the result
Use realistic price sequences or exported data for deeper analysis rather than treating linear price movement as a forecast.
Run scenarios instead of one answer
Change the most uncertain input and compare outcomes. A calculator is most useful when it shows sensitivity, not when one estimate is treated as a guarantee.
Limits and assumptions
Fees, taxes and actual execution prices are not included.
