Historical DCA backtest

Apply regular purchases to actual historical USD price observations.

Uses actual historical USD observations from the selected source, starting with a purchase on your start date. Daily and weekly schedules use UTC dates; monthly schedules retain your start-day and clamp to shorter months. Each purchase uses the first observation on that UTC day. Missing days stop the backtest. Fees come out of each contribution; exit fees, spread, tax, and intraday execution are excluded.

Regular investment definition: Investor.gov dollar-cost averaging. Historical data access depends on the provider and configured history range.

Your calculation inputs stay in this browser. Market and history requests send the selected asset and date range to our price-data endpoint. Reference methodology checked October 1, 2026.
