How it works
A crypto profit calculator finds your gain or loss on a trade: the difference between sale and purchase value, times the quantity, minus fees. The same math gives your percentage return for comparing trades.
Crypto profit
Profit = (sell price − buy price) × quantity − fees Return% = profit ÷ (buy price × quantity) × 100
- buy/sell price
- price per coin in and out
- quantity
- number of coins
- fees
- exchange/network fees both ways
Worked example
- Bought 0.5 BTC at $30,000
- Sold at $40,000, $50 total fees
- Gross = (40,000 − 30,000) × 0.5 = $5,000
- Net = 5,000 − 50
Profit ≈ $4,950 — a ~33% return.
Good to know
- Crypto is highly volatile; gains can reverse fast, so size positions accordingly.
- Trading fees and network (gas) fees on both ends eat into returns, especially on small trades.
- In many countries crypto disposals are taxable events — keep records of cost basis.
