Assumed nominal BTC growth compounded monthly; future DCA at month end. Historical returns are not compounded again.
A calculator on stored data, not an order and not the DNH20 print. Not investment advice. Ignores fees, slippage, tax, inflation and withdrawals. History runs from the first stored close on the chosen date to the latest stored close (2026-10-05); an initial buy happens once and DCA starts at the next interval; missing dates are never filled. Coinbase BTC-USD spot is checked on open and every 5 minutes while the page is visible. DCA can lower or raise the average cost versus one upfront buy and does not remove BTC price risk. The future-growth section is an assumption, not a forecast or a guaranteed yield.
