Crypto capital gains calculator (FIFO / LIFO / average cost)

Work out the capital gain or loss on a crypto disposal using FIFO, LIFO or average-cost basis. Enter your buys and the disposal; the calculator matches the disposed units to your acquisitions and shows the cost basis and resulting gain.

How this calculator works

It runs entirely in your browser — nothing you enter is sent anywhere. It is a general estimate: which cost-basis methods are permitted, and the tax rate that applies, depend on your jurisdiction. Check the relevant country page and a qualified professional before you rely on a figure.

What it does not do

It does not apply any country’s specific rates, allowances, or holding-period rules, and it is not tax advice.
