DCA calculator for crypto (dollar-cost averaging)

What dollar-cost averaging means

Dollar-cost averaging (DCA) means buying the same dollar amount of a coin on a fixed schedule, for example $25 every week, whatever the price. When the price is low your $25 buys more coins, and when it is high it buys fewer. Over time your average cost per coin sits between the highs and lows.

DCA does not guarantee a profit. It removes the stress of choosing the "right day" and spreads your risk over time.

How the calculator works

• Price for each buy: a straight line from the first price to the last price.
• Coins per buy = amount × (1 − fee) ÷ price that day.
• Average cost = total invested ÷ total coins.
• Value = total coins × the price when you sell.
• Lump-sum comparison: the same total money spent in one buy at the first price.

Everything is calculated in your browser. Nothing is sent or stored.

When DCA helps and when it does not

• If the price falls then recovers, DCA usually beats a single early buy, because you picked up cheaper coins on the way down.
• If the price only rises, one early buy usually wins, because every later buy costs more.
• If the price only falls, both lose. DCA just loses more slowly.

Try all three paths by changing the first and last price.

Tips

• Use the fee your exchange really charges on small recurring buys. It is often higher than the trading fee.
• Pick an amount you can keep buying for months without selling in a panic.
• Keep coins you plan to hold in your own wallet. See the Crypto Starter Kit for a step-by-step setup.
