Terms of Use

CryptoGainsCalc is a free calculator provided for general estimation and educational purposes only. It is not tax, financial, or legal advice, and using it does not create any professional relationship.

The calculator uses FIFO matching and US federal short-term/long-term conventions; it does not compute tax owed, does not account for every possible tax rule (wash sales, fees, non-US regimes, specific-lot identification), and its output should always be verified against your own records and a qualified tax professional before you rely on it for filing.

The site is provided "as is," without warranty of any kind. We are not liable for any decision made based on its output.

Some pages contain affiliate links (marked as such) to third-party tax software. If you sign up through one of those links, we may earn a commission at no extra cost to you. This never affects the calculator's output.
