Crypto profit calculator
Enter your entry price, exit price, and position size. The calculator shows profit or loss in absolute and percentage terms, after an optional trading fee. All math is done in your browser — nothing is sent to us.
How this calculator works
Entry cost is buy_price × size (or just the USD amount if you chose USD as size units). Exit value is sell_price × size_coins. We apply the trading fee twice — once on entry, once on exit — because every round trip pays both. The displayed P&L is after fees.
What this calculator does not do
- Slippage on illiquid markets — if you size too large for the order book, your realised price will be worse than the quoted price.
- Funding costs on perpetual futures — for leveraged positions held more than a few hours, the cumulative funding rate can dwarf trading fees.
- Taxes — taxation of crypto gains varies by jurisdiction; consult a licensed professional.
- Currency conversion — if you buy with EUR or another fiat, factor the FX at both ends.
