Tool
Average price across several purchases
Enter the quantity and price for each purchase. Empty rows are ignored; completed rows are weighted by quantity.
Formula
Average price = sum of (quantity × price) ÷ total quantity. A simple average of the prices, without accounting for quantity, gives the wrong result when purchase sizes differ.
What is not included
Fees, taxes, deposits and withdrawals are not added automatically. To include them in your cost basis, first convert all costs into one currency and use the adjusted values.
