Crypto Profit & Loss Calculator
To calculate crypto profit, subtract your total cost (purchase amount plus the buy fee) from your net proceeds (sale amount minus the sell fee). Profit = (quantity × sell price × (1 − sell fee%)) − (quantity × buy price × (1 + buy fee%)). Divide that profit by your total cost for the percentage return. This calculator does the arithmetic instantly in your browser; just enter your prices, quantity and the fee each exchange charged.
How it works
Exchanges charge a fee on both the buy and the sell, so your true cost is higher and your true proceeds are lower than the headline prices suggest. The calculator applies the buy fee on top of your purchase and deducts the sell fee from your proceeds.
Net profit is proceeds minus cost; return on investment (ROI) is that profit divided by what you actually paid. A positive number is a gain, a negative number is a loss. The result is an estimate for general information, not financial advice.
Net profit = qty × sell × (1 − sellFee) − qty × buy × (1 + buyFee)
Estimates for general information only — not financial or tax advice.
Frequently asked questions
Does this include exchange fees?
Yes. Enter the percentage fee for each side and the calculator adds the buy fee to your cost and subtracts the sell fee from your proceeds.
Is the profit before or after tax?
Before tax. The number shown is your economic gain. To estimate tax owed on it, use the crypto capital-gains tax estimator.
Can I use it for any coin?
Yes — it is unit-agnostic. Enter the quantity of any coin and your prices in any single currency; just stay consistent.
Are my numbers sent anywhere?
No. The calculation runs entirely in your browser and nothing is stored or transmitted.
