Method
How it works
Enter the coin amount and unit price for two purchases. Each amount is multiplied by its price to find cost, then the combined cost is divided by the total coin amount.
The result is a quantity-weighted average, so the larger purchase has more influence. The calculation does not include trading fees or transfers.
