How this calculator works
We take your monthly amount and split it across every month from your start year through today, using approximate year-end bitcoin prices and interpolating between them for the months in between. Each month "buys" whatever fraction of a bitcoin that amount would have gotten at that interpolated price.
This is a simplified backtest, not a tick-by-tick historical model — bitcoin's actual monthly prices swung far more than a straight line between year-end points. Treat the output as directionally accurate, useful for understanding the shape of dollar-cost averaging, not as investment advice or a precise return projection.
Frequently asked questions
What is dollar-cost averaging (DCA)?
Buying a fixed dollar amount of an asset on a regular schedule — weekly or monthly — regardless of price. It averages your purchase price over time instead of trying to time a single entry point.
Is DCA better than a lump sum?
Historically, investing a lump sum immediately has outperformed DCA more often than not for assets that trend upward over time. DCA's real benefit is behavioral — it removes the temptation to time the market and smooths out volatility.
How accurate is this calculator?
It uses approximate year-end bitcoin prices and interpolates between them for months within a year. It's directional and educational, not a precise backtest of daily purchase prices.
