Crypto DCA Calculator
Dollar-cost averaging means investing a fixed amount on a regular schedule so you buy more units when prices are low and fewer when they are high. This calculator takes your contribution per period, the number of periods, your average purchase price across the plan, and a target price to value the holding. It returns total invested, units accumulated, average cost per unit, and the value and profit or loss at the target price. Crypto prices are volatile, so the average price is a user input rather than a sourced figure.
Dollar-cost averaging formula
Total invested = contribution * periods
Units accumulated = total invested / average purchase price
Value at target = units accumulated * target price
Profit / loss = value at target - total invested
Average purchase price is the blended price across all buys. Units equal dollars invested divided by that average, and the holding is valued at your chosen target price.
Things to know
- DCA smooths entry price and reduces timing risk but does not guarantee a profit.
- The average purchase price reflects all your buys; lower entries pull it down.
- A downtrend over the whole window can still produce a loss despite averaging.
- Each purchase is a separate tax lot with its own basis and holding period.
- Buying is not taxable; selling, trading, or spending crypto is.
Crypto DCA: frequently asked questions
What is dollar-cost averaging?
Dollar-cost averaging (DCA) is investing a fixed dollar amount at regular intervals regardless of price. You buy more units when the price is low and fewer when it is high, which smooths your average entry price and removes the pressure to time the market. This calculator models a fixed contribution over a number of periods.
How is the average cost per unit calculated with DCA?
Total invested is the contribution per period times the number of periods. Units accumulated is the sum of contribution divided by price for each period. Average cost per unit is total invested divided by total units. With constant contributions this is the harmonic-style average that DCA produces.
Why does this use one average price rather than each period's price?
To stay deterministic without guessing historical prices, this tool computes accumulation from an average purchase price you supply alongside total invested, and then values the holding at a target price. If you have each period's price, the underlying mathematics is the same: total invested divided by total units gives the blended cost.
Does DCA guarantee a profit?
No. DCA reduces timing risk and smooths your entry price, but if the asset trends down over your whole investment window you can still lose money. It is a discipline for managing volatility and behaviour, not a guarantee. Crypto assets are especially volatile.
Is each DCA purchase a taxable event?
Buying is not a taxable event; selling, trading, or spending crypto is. Each lot you buy has its own cost basis and holding period for capital gains purposes. This tool does not compute tax. See IRS digital asset guidance and keep records of every purchase.
