Crypto average cost and averaging down calculator
If you bought a coin several times at different prices, your real cost is the amount-weighted average, not the simple average of prices. Enter each buy's price and the amount you paid; the calculator shows your average cost, total quantity and P/L at the current price. Add a target average to see how much you'd need to buy at the current price to reach it.

Any currency works (TRY, USDT, $) as long as all amounts use the same one. Add fees to the amount if you like. Not investment advice.
How is average cost calculated?
Average cost = total amount spent ÷ total quantity bought. Each buy's quantity = amount paid ÷ price.
Example: $1,000 at $100 and $1,000 at $50 → 10 + 20 = 30 units for $2,000; average $66.67, not the $75 simple average.
Averaging down
Buying below your average lowers it. Quantity needed for a target average: (total cost − target × quantity held) ÷ (target − current price). The target must lie between the current price and your current average.
Averaging down grows a losing position: if price keeps falling, so does the loss. This is a calculation, not a recommendation.
| Case | Held | Average | Price | Target | Buy needed |
|---|---|---|---|---|---|
| 1 | 10 units | 100 | 50 | 75 | 500 (10 units) |
| 2 | 10 units | 100 | 50 | 60 | 2,000 (40 units) |
| 3 | 10 units | 100 | 80 | 90 | 800 (10 units) |
What is DCA?
Dollar cost averaging means buying a fixed amount at regular intervals. A fixed amount buys more units when price is low, so the average cost ends up below the simple average of prices.
Frequently asked questions
How do you calculate crypto average cost?
Divide the total amount spent by the total quantity bought; each buy's quantity is the amount paid divided by its price.
How much do I need to buy to average down?
(Total cost − target average × quantity held) ÷ (target average − current price). The target must be between the current price and your average.
