Free tool
Cost basis
Add purchase lots. The tool totals them, computes a weighted average cost, and marks unrealised gain or loss at the live or override price. It does not give tax advice.
General information only, not financial advice. Check with your accountant or adviser.
Inputs stay in this browser under the localStorage key apex-tool-cost-basis. They are not sent to a server. Clearing removes that key.

Oldest first
Add a complete lot to see an order.
If bitcoin were sold, first-in-first-out would treat the oldest lot as sold first. This tool does not model a sale and does not calculate tax. Check tax treatment with an accountant.
