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
  1. Gross = (40,000 − 30,000) × 0.5 = $5,000
  2. 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.
