Crypto average buy price calculator

How the calculation works

Weighted fill price = sum(quantity × price) ÷ sum(quantity). Fee-inclusive average cost = [sum(quantity × price) + sum(fees)] ÷ sum(quantity).

Worked example

Example: one token at 100 and two at 130 cost 360 before fees. Three tokens have a weighted fill price of 120.

How to use the result

The required columns are quantity, price and fee, in that order. Keep the header exactly as shown. Quoted cells, thousands separators and blank rows are not supported.

The fee-free fill price and fee-inclusive average answer different questions. The latter spreads the entered purchase fees across the total token amount.

What this result leaves out

• Purchases only. Sales, transfers, token-denominated fees and acquired rewards are outside this input format.
• This simple purchase average does not determine a jurisdiction's tax basis or select an accounting method.
