Worked example
Buy 0.01 BTC at 45,000 USD, another 0.01 BTC at 60,000 USD and a third 0.01 BTC at 75,000 USD. You hold 0.03 BTC for 1,800 USD, an average of 60,000 USD per bitcoin. At today's price that is worth 2,246 USD: a profit of 445.83 USD, or +24.8%.
How it works
Total spent = the sum of each purchase's bitcoin × its price. Total bitcoin = the sum of the bitcoin bought. Average price = total spent ÷ total bitcoin, a weighted average. Profit = total bitcoin × today's price − total spent, and the return is profit ÷ total spent. Fees are not added, so include them in the price you enter if you want them counted.
Frequently asked questions
How do I calculate my average bitcoin buy price?
Add up everything you spent and divide by the total bitcoin you bought. Do not average the prices themselves: a large purchase should weigh more than a small one.
Is my average cost the same as my break-even price?
Close, but not equal. Selling above your average cost is a profit before fees and tax, and the exchange's selling fee moves the real break-even a little higher. The profit calculator includes fees on both sides.
Does the average cost decide my tax?
It can. Some countries tax a sale by averaging your purchases, others match specific purchases, and the rules differ widely. The country tax guides on this site explain what each authority has published.
