About Crypto Tax Lot Calculator

This free tool helps you calculate capital gains on cryptocurrency sales using the FIFO (First In, First Out) method, which is the default accounting method used by most tax authorities. Track your buy lots, enter your sale details, and get an instant breakdown of your cost basis, proceeds, and estimated tax liability.

FIFO Method

Uses the First In, First Out accounting method — the default required by most tax authorities for cryptocurrency disposals.

Multiple Buy Lots

Add as many buy lots as needed with date, quantity, and price. Each lot is tracked individually through the sale.

Short vs Long Term

Determines the holding period for each lot sold — short term (under 1 year) vs long term (over 1 year) — which affects tax rates.

Tax Estimate

Get estimated capital gains tax at both short-term and long-term rates to understand your potential tax liability.

📋 Common Use Cases
