Crypto Dollar-Cost Average Calculator
Dollar-cost averaging is buying a fixed amount of crypto at regular intervals, letting your average price settle between the highs and lows. This calculator takes your per-period contribution, the number of periods, and the average purchase price across those periods, then returns your total invested, total coins held, and your average cost per coin. Compare that average cost to the current price to see your position at a glance.
Dollar-cost average formula
Total invested = contribution * periods
Coins per period = contribution / average price
Total coins = coins per period * periods
Average cost = total invested / total coins (= average price)
Current value = total coins * current price
Profit / loss = current value - total invested
When each contribution is the same fixed amount and the average price is the simple average across periods, your weighted average cost equals that average price. Using actual per-period prices would weight cheaper purchases more heavily.
Reading the result
- Total invested is your cash outlay before fees.
- Total coins held is what your fixed contributions accumulated.
- Current value marks the holdings to the current price you entered.
- Profit or loss is the difference, positive when the current price beats your average cost.
Dollar-cost averaging: frequently asked questions
What is dollar-cost averaging?
Dollar-cost averaging (DCA) means investing a fixed amount of money at regular intervals regardless of price. You buy more units when the price is low and fewer when it is high, which smooths out the average price you pay and removes the pressure of timing the market.
How is the average cost per coin calculated?
Average cost per coin is the total amount you invested divided by the total number of coins you accumulated. Because each fixed purchase buys a different number of coins depending on the price at the time, the average is weighted by how many coins each purchase added.
Why might my average cost differ from the simple average of prices?
When you invest a fixed dollar amount, lower prices buy more coins than higher prices, so cheaper purchases carry more weight. This pulls your average cost per coin below the plain arithmetic average of the prices, which is one of the structural advantages of dollar-cost averaging.
Does this account for fees or taxes?
No. This shows the average purchase price and holdings before exchange fees and before any tax on gains. Add trading fees to your contribution and consult the tax rules in your jurisdiction for the treatment of crypto disposals.
