BTC DCA Engine answers one question with arithmetic instead of opinion: what would a regular buying plan have been worth? Give it an asset, an amount and a schedule — daily, weekly, monthly or quarterly — and a start date, and it returns what you put in, what it would be worth at the last close, the profit, the simple and money-weighted returns, the units held, and end-of-year checkpoints along the way. It can compare plans side by side and rank them, and it can return the individual purchases behind any figure. Every answer carries a link that reopens the same run in the web app, pinned to the exact data it was computed from, so a number in a conversation can be checked rather than taken on faith. Prices come from published daily closes; inflation and rate series come from the St. Louis Fed. There is no forecasting, no advice, and no trading — it reads history and does the sums. Free with no account: seven assets including Bitcoin, Ethereum, Solana, XRP, the S&P 500, the Nasdaq 100 and gold, and two plans per comparison. A BTC DCA Engine account covers the rest of the catalogue, larger comparisons, and the risk, inflation, lump-sum and rules-based overlays.
