Crypto Profit Calculator

How it is calculated

One fee percentage is applied to both sides of the trade. The cost of the buy is cost = buy price × quantity × (1 + fee ÷ 100), so the fee is added on top. The proceeds of the sell are proceeds = sell price × quantity × (1 − fee ÷ 100), so the fee is deducted. Then profit = proceeds − cost and ROI = profit ÷ cost × 100.

Prices are per unit in dollars, quantity is the number of coins (decimals such as 0.5 are fine and it must be above zero), and the fee is the exchange's percentage per trade, taken as 0 if left empty. A loss appears as a negative profit and ROI. Because a fee is charged on both legs, the price must rise by slightly more than twice the fee percentage before you break even. The tool does not include network or withdrawal fees, spread, or tax on gains.

Common mistakes

• Entering the total amount spent as the buy price. The fields are the price per coin and the quantity, and the tool multiplies them.
• Entering the fee as 0.005 instead of 0.5. The field is in percent, so 0.5% is 0.5.
• Entering the fee in dollars. The field only takes a percentage of the trade value.
• Forgetting that the fee is charged twice, once when buying and once when selling. A sale at the same price as the purchase therefore still shows a loss.
• Treating the profit as taxable income without checking local rules, or expecting network and withdrawal fees to be in it. They are not.
