What the Crypto Tax Calculator does
Most jurisdictions treat crypto as property, so disposing of it — selling, swapping, or spending — realises a capital gain or loss. The gain is proceeds minus cost basis minus fees, and tax applies to what remains after any allowance and offset losses.
Formula
Capital gain = Proceeds − Cost basis − Disposal feesTaxable gain = max(0, Gain − Losses carried forward − Allowance)Tax = Taxable gain × Tax rate

Frequently asked questions
Is swapping one coin for another taxable?
In many jurisdictions, including the US and UK, yes — it is treated as disposing of the first asset. Check your local rules, as this varies.
What is cost basis?
What you paid to acquire the asset, including fees. Which units you are deemed to have sold depends on the accounting method your jurisdiction requires — FIFO, average cost or specific identification.
