Each row takes the bitcoin held at the end of that year and values it at the price for December 31 (UTC). ROI is the gain on everything paid in up to then. The current year, marked YTD, is valued at $81,594 per BTC, the same price as the figures above.
How this is calculated: purchases are simulated on UTC calendar days. Each day is priced from Coinbase: one close per UTC day. The price history was fetched on Oct 22, 2026 at 13:36 UTC, and a row dated that day is the latest trade at that moment, not a close. Amounts are in USD, and no exchange fees are applied. ROI is the gain as a percentage of what you put in. XIRR is the annualized return, meaning the yearly rate of growth, adjusted for money going in a bit at a time. Max drawdown is the deepest fall the stack's value took from its own earlier peak, checked on every day of the plan and not only on purchase days. One price a day cannot show a fall that happens inside a single day. The full methodology covers the rest.
