Crypto Profit & Loss Calculator

P&L = (sell price − buy price) × quantity − fees on both sides. If you bought 0.5 BTC at $40,000 ($20,000 plus $50 fee) and sold at $60,000 ($30,000 minus $75 fee), your profit is $30,000 − $20,000 − $50 − $75 = $9,875. Always include exchange fees, network/gas fees, and any spread to get a true picture of returns.

The IRS treats crypto as property. Selling, trading one crypto for another, or spending crypto on goods are taxable events. Held over a year: long-term capital gains rates (0%/15%/20%). Held under a year: ordinary income rates (up to 37%). Each disposal must be reported on Form 8949; exchanges issue Form 1099-DA starting with 2025 transactions.

Selling a losing position to realize a capital loss offsets gains elsewhere and up to $3,000/year of ordinary income. Crypto is currently exempt from the wash-sale rule that applies to stocks, so investors can sell at a loss and immediately repurchase the same coin - a meaningful tax-planning advantage. (This may change as legislation evolves.)

Trading costs erode returns. Centralized exchanges typically charge 0.1%–0.6% per trade. On-chain DEX trades incur gas fees plus liquidity-pool fees, often 0.3%–1%. Bid-ask spreads can add another 0.1%–2% on illiquid pairs. Across a buy and sell, total round-trip costs of 1%–4% are common - always factor them into expected returns.
