DCA Average Cost Simulator

Give it a list of prices and a fixed amount per period, and see what your average cost actually works out to and whether you're up or down right now. What follows is an arithmetic illustration based on the prices you enter, not a profit forecast — nobody knows the real price path in advance.

How it works: you buy the same amount every period, so coins bought that period = amount per period ÷ that period's price; total invested = amount per period × number of periods; average cost = total invested ÷ coins accumulated; current value and P&L use the last price in the sequence. This is an arithmetic illustration of the prices you enter, not a profit forecast, and it doesn't include fees. This tool runs entirely in your browser — nothing is sent, uploaded or saved.

How this tool works

DCA means you put in the same amount every period, no matter the price. When the price is low the same money buys more coins; when it's high you buy fewer — so your average cost gets pulled down a little by the extra buying at the lows. That's cost averaging. The arithmetic: split the price list you enter at each comma into one period each, divide the fixed amount by that period's price to get the coins bought, and add them all up for coins accumulated; total invested is the amount per period times the number of periods; divide one by the other for average cost. Then take the last price in the sequence as "now," work out the current value, and compare it against total invested to get your unrealized gain or loss.

What it can't tell you: where the price goes next, whether this coin is worth holding for the long haul, or when to stop your plan. The tool just averages the prices you assumed and shows you the result — DCA is not a guaranteed win. If the price falls the whole way and never recovers, a low average cost is still a loss; whenever the last price in the sequence is low, the result comes out negative too. To first work out whether DCA suits you, see the complete DCA guide and which coins to DCA.

Using the number to decide

Hold your average cost up against the price you'd be happy owning for the long run: if it's clearly below what you think is fair value, the averaging is doing its job; if you realize you're just white-knuckling a coin that only ever falls, rethink whether you picked the wrong coin or should use a different approach. You can also line it up against the grid profit simulator to see which fits a choppy market better. And remember real buys carry fees — see how Binance fees work.
