Question 1

How is crypto profit calculated?

Accepted Answer

Profit is calculated as: (Sell Price - Buy Price) × Quantity - Buy Fee - Sell Fee. ROI (Return on Investment) is the profit divided by total cost (including fees), expressed as a percentage.

Question 2

Does this tool support all cryptocurrencies?

Accepted Answer

Yes. The calculator works with any cryptocurrency — Bitcoin (BTC), Ethereum (ETH), Solana (SOL), Dogecoin (DOGE), and thousands of altcoins. You simply enter the buy and sell prices in your preferred currency (USD, EUR, etc.).

Question 3

Are exchange fees included?

Accepted Answer

Yes. The tool includes both buy-side and sell-side fees, which can be entered as a percentage (most exchanges charge 0.1%-0.5%) or as a flat amount. This gives you the most accurate net profit calculation.

Question 4

Is the data private?

Accepted Answer

Yes. All calculations happen entirely in your browser. No data is sent to any server, no account or signup required, and your trade history is never stored anywhere.
