What Crypto DCA Calculator does and how it behaves

Crypto DCA Calculator replays a recurring cryptocurrency investment over a past date range. It converts each scheduled cash contribution into coin units at the corresponding historical price, accumulates those units, and summarizes the amount invested, average cost basis, portfolio value, and return over time. A recurring amount is not the total budget: entering $100 for a weekly schedule means another $100 is invested on every scheduled purchase date in the selected period.

How the result is produced

1

Scheduled purchases

The chosen recurring amount is placed on each scheduled date within the selected historical window. At every purchase point, that cash amount is divided by the cryptocurrency's recorded price to obtain units bought. Those units are added across the schedule. Lower-price purchases therefore acquire more units than higher-price purchases made with the same cash contribution.

2

Cost and return

The calculator totals the scheduled contributions and accumulated coin units. Average cost basis is contributed cash divided by units acquired. It values the accumulated position using the relevant historical price, then expresses the difference from contributions as a gain or loss and a return percentage. The visualization shows how the simulated position changed during the selected period.

Good uses

  • Reconstruct how a weekly Bitcoin purchase plan would have performed across a specific historical market cycle.
  • Run separate monthly and weekly scenarios to see how contribution timing changes units acquired, average cost, and historical return.
  • Estimate the historical cost basis and accumulated coin quantity for a recurring purchase amount before configuring a similar exchange order.

Limits and checks

  • Historical performance is path-dependent. Changing the start date, end date, or purchase cadence can materially change the result, even when the recurring amount stays unchanged.
  • A scheduled purchase may not match an actual exchange fill. Price timestamps, time zones, intraday movement, and execution timing can produce different quantities.
  • Do not read the displayed value as guaranteed net proceeds. Trading fees, spreads, slippage, custody costs, and taxes can reduce an investor's actual outcome.

Common questions

Does this calculator predict what my DCA plan will earn?

No. It applies a recurring purchase schedule to historical cryptocurrency prices and reports the resulting hypothetical position. It does not establish a future growth rate or show that the same pattern will recur. Use it to inspect how a plan behaved during a chosen past period, not as a forecast.

Why might the result differ from my exchange statement?

An exchange records actual execution prices, timestamps, fees, spreads, and any skipped or modified orders. A historical simulation uses its scheduled dates and available price observations. Even a purchase labeled with the same calendar date can receive a different price, so the acquired units and average cost may not match.
