Bitcoin DCA Calculator
See what buying a fixed amount on a fixed schedule would actually have returned — and what changes if you buy more when our accumulation index says the market is cheap, spending exactly the same money overall.
How this is calculated
Every buy is executed at the real daily closing price from our own dataset — the same series that drives the accumulation index on the rest of the site. Flat DCA buys the same amount on every scheduled date. The weighted version buys 1.5× on days the accumulation composite reads 65 or higher (the value end), 0.5× when it reads 35 or lower (the stretched end), and 1× in between — then every buy is scaled so the total amount invested ends up identical to flat DCA. Only the timing of the money differs, never the amount.
This is a backtest over the window shown, not a strategy recommendation. The window covers a limited stretch of market history; a different period can easily favour the other side. Treat it as evidence that when you buy matters, not as a promise about what comes next.
Dollar-cost averaging — questions answered
What is dollar-cost averaging?
Buying a fixed amount on a fixed schedule regardless of price. It removes the timing decision, smooths your entry across highs and lows, and makes volatility work for you: the same money buys more coins when price is low.
Is DCA better than buying all at once?
In a market that mostly rises, a single early lump sum usually wins on paper. DCA wins on behaviour and on drawdown: you are far less likely to buy everything at a local top, and far more likely to keep buying through a decline. Which one is better for you depends on whether you can actually hold through a 60% drawdown.
What is the accumulation-weighted version?
The same schedule and the same total money, but the size of each buy leans on WhaleRoom's 17-signal accumulation composite — bigger buys when the signals cluster in the value zone, smaller when they are stretched. It is DCA with a valuation tilt, not market timing: you never skip a buy and you never spend more overall.
How far back does the data go?
The calculator uses our own stored daily series, which currently starts in August 2024 — the range is shown under the inputs. We use our own data rather than a third-party API so the numbers here match the indicators used everywhere else on the site.
