Dollar-Cost Averaging Describes a Contribution Schedule
Dollar-cost averaging means contributing a set amount at repeated intervals rather than investing the entire planned amount at once. The calculator tracks the cash contributed and the modeled value under its return assumptions.
It does not predict future prices or prove that recurring investing will outperform lump-sum investing. Market path, fees, taxes and the timing of actual purchases determine realized results.
Dollar-cost averaging describes a schedule, not a guarantee that buying gradually will outperform investing a lump sum. Its practical benefit is that the same contribution buys more units when prices are lower and fewer when prices are higher, while removing the need to choose one entry date for every dollar. The calculator is most useful for seeing how regular contributions accumulate under an assumed return; it cannot reproduce the sequence of real market prices that determines the actual number of shares purchased.
Frequently Asked Questions
Does dollar-cost averaging guarantee a profit?
No. Recurring purchases change entry timing but do not remove market risk or guarantee positive returns.
Why separate contributions from investment growth?
It shows how much of the ending modeled value came from money added versus the assumed return on that money.
Does DCA guarantee a lower average purchase price?
No. The result depends on the path of market prices. DCA spreads purchases across time, but a steadily rising market can make earlier lump-sum investment outperform.
