How is crypto profit calculated?
The basic formula is straightforward:

- Profit / Loss = Total value − (Number of coins × Buy price) − Fees
- ROI = (Profit ÷ Total cost) × 100
- CGT estimate = Profit × Tax rate ÷ 100
Do I pay tax on crypto profits in the UK?
In the UK, cryptocurrency is subject to Capital Gains Tax (CGT). You only pay CGT on gains above your annual allowance (currently £3,000 for 2024/25). The basic rate is 18% and the higher rate is 24% for crypto assets. Always consult a qualified tax professional for advice specific to your situation.

What is ROI in crypto?
ROI stands for Return on Investment. It tells you what percentage gain or loss you've made relative to what you originally invested. A 100% ROI means you've doubled your money. A −50% ROI means your investment has halved in value.
