How the Crypto Tax Calculator Works

The formula for capital gains tax on crypto is:

Gross Gain = (Sell Price − Buy Price) × Quantity
Taxable Gain = Gross Gain − Annual CGT Allowance
Estimated Tax = Taxable Gain × Capital Gains Tax Rate
Net Gain = Gross Gain − Estimated Tax

Variables: Buy Price is the purchase price per coin. Sell Price is the disposal price per coin. Quantity is the number of coins sold. Annual CGT Allowance varies by jurisdiction (UK: £3,000, US/AU/EU: £0). Capital Gains Tax Rate depends on your income tax band and jurisdiction (UK: 18% basic / 24% higher rate, US: 15% / 20%, AU: 23.5% / 47%, EU: 20%).

How this calculator works

This calculator uses a simplified CGT formula: it calculates your gross gain from the difference between sell and buy values, deducts the annual CGT allowance for your jurisdiction, then applies the appropriate tax rate to give an estimated liability. All logic is deterministic and based on the inputs you provide, no data is stored or transmitted.

Understanding crypto capital gains tax

Most countries treat cryptocurrency as a capital asset rather than currency. This means every disposal, selling, swapping one crypto for another, or spending crypto, is potentially a taxable event. Your gain is the difference between what you paid (cost basis) and what you received (proceeds). Each jurisdiction has different allowances, rates and reporting requirements. This tool gives a rough estimate, for accurate reporting always use dedicated tax software or a qualified accountant.
