Disclaimer
This is an estimate. Not financial advice. This calculator provides a simplified approximation of UK Capital Gains Tax on crypto disposals. It does not account for section 104 pooling, same-day or 30-day matching rules, or other assets that may use your annual allowance.
Consult a qualified tax adviser before making decisions based on these figures. For detailed information on how CGT applies to crypto, read our Capital Gains Tax guide.
How This Calculator Works
Enter your disposals
Add each crypto sale: the price you bought at, the price you sold at, and the quantity. The calculator works per-unit, so enter the price per coin or token.
Gains are netted
Gains and losses are added together. The £3,000 annual allowance is applied. Only the amount above the allowance is taxable.
Tax is calculated
Tax is shown at both rates: 18% (basic rate) and 24% (higher rate). Which rate applies depends on your total taxable income for the year.
