Step by step
Open Crypto Cost Basis Calculator
Visit /tools/crypto-cost-basis-calculator in any modern browser. The tool loads instantly and runs entirely on your device, so no inputs are transmitted to a server.
Gather your inputs
Have your buy lots (quantity, price, fees), sale lots ready. Accuracy on the output depends entirely on the quality of these numbers. If a value is uncertain, use the most realistic figure rather than rounding aggressively.
Enter the values
Fill each field in turn. Crypto Cost Basis Calculator validates ranges as you type, so an obvious typo (for example a negative balance where one cannot exist) will flag immediately.
Read the result
The output is a realised gain, cost basis per coin, computed using fifo or specific identification lot matching. Treat it as a precise answer to the question you posed, not an approximation.
Verify and compare
Re-run the calculation with a slightly different input to test sensitivity. For deeper comparison against another approach, see related tools in the Crypto hub or pick a related crypto cost basis tool below.
When to use Crypto Cost Basis Calculator
