How the crypto DCA calculator works

Each buy converts your fixed dollar amount into coins at whatever the price is that day, so coins bought equals the buy amount divided by the price. The tool repeats this for every period across your horizon, tallies the coins and dollars, and values the stack at the final price. The shaded area is your portfolio value and the dashed line is the total cash you put in.

Because cheaper periods hand you more coins, your blended entry price ends up below the average market price over the run. That lower average cost is the whole point of dollar-cost averaging, and the calculator shows it directly alongside the coin count.

A quick example

Suppose you buy 100 dollars of Bitcoin every week for 3 years starting at 30,000 dollars, and assume roughly 25 percent average annual growth. You invest about 15,600 dollars across 156 buys, accumulate a fraction of a coin at an average cost well under the ending price, and watch the value line pull away from the flat invested line as the position compounds.

Things to keep in mind

Crypto is highly volatile and these projections assume a smooth average rather than the sharp drawdowns real markets deliver, so treat the output as a planning sketch. Factor in exchange fees and taxes, and never invest money you cannot afford to lose. For plain guidance on crypto risks, see the SEC Investor.gov crypto pages.

Frequently asked questions

What is dollar-cost averaging in crypto?

Dollar-cost averaging means buying a fixed dollar amount of a coin on a regular schedule, such as 100 dollars every week, regardless of the price that day. You end up buying more coins when the price is low and fewer when it is high, which smooths out your average entry price over time.

How does this calculator project the future price?

It applies the average annual growth rate you enter to the starting price and spreads it across every buy, then adds a small repeating up and down swing so the chart resembles a real market path. It is an illustration, not a forecast, because no one can predict crypto prices.

What is my average cost per coin?

Your average cost is the total dollars you invested divided by the total coins you accumulated. Because DCA buys more coins at lower prices, this average is usually below the simple midpoint of the price range, which is the main benefit of the strategy.

Is DCA better than buying all at once?

It depends on the price path. If a coin rises steadily, a single lump sum at the start tends to win. If prices are volatile or fall before recovering, spreading purchases reduces the risk of buying everything at a bad moment. DCA mainly trades some upside for lower timing risk and less stress.
