Crypto Profit Calculator

Cryptocurrency trading can be profitable, but without accounting for fees and understanding your true return on investment, it is easy to overestimate gains or underestimate losses. This crypto profit calculator gives you a complete picture of any trade by factoring in buy price, sell price, quantity, and trading fees -- all computed instantly in your browser.

The calculator supports two input modes. The default "Buy/Sell" mode is for planning or evaluating a trade where you know both the purchase price and the sale (or target) price per coin. The "Current Holdings" mode is for checking the value of coins you already own -- enter your average buy price, the current market price, and the quantity you hold to see your unrealized profit or loss.

Trading fees are one of the most overlooked factors in crypto profitability. Even a small fee of 0.1% applied to both the buy and sell side can noticeably reduce profits on frequent trades. This calculator applies your specified fee percentage to both the buy transaction and the sell transaction, then deducts the total fees from your gross profit to show the true net profit or loss. The fee slider ranges from 0% to 5% to cover everything from zero-fee promotions to higher-cost fiat on-ramps.

The results section breaks down every component of the trade: total investment cost, current or sale value, gross profit before fees, total fee deductions, net profit after fees, your return on investment (ROI) as a percentage, and the break-even price -- the minimum sell price needed to cover your investment plus fees. All profit figures are color-coded green for gains and red for losses, making it immediately clear whether a trade is profitable.

A visual comparison bar shows your investment cost against the current or projected value, giving you an intuitive sense of the magnitude of your gain or loss. Whether you are evaluating a potential trade before executing it or reviewing the performance of coins you already hold, this calculator provides the complete financial picture in seconds.

The profit calculation uses standard trading formulas. Investment cost is calculated as buy price multiplied by quantity. Sale value is sell price multiplied by quantity. Gross profit is the difference between sale value and investment cost. Trading fees are applied to both the buy side (investment cost multiplied by fee rate) and the sell side (sale value multiplied by fee rate). Net profit equals gross profit minus total fees. ROI is calculated as (net profit / investment cost) * 100. The break-even price is derived by solving for the sell price where net profit equals zero, accounting for fees on both sides: break-even = (buy price * (1 + fee rate)) / (1 - fee rate).
