How to use it
- Enter the crypto amount you hold.
- Input the buy price per unit in USD.
- Input the sell price per unit in USD.
- Set the transaction fee rate as a decimal and view profit and ROI.
What it does – The Crypto Profit Calculator takes the amount of a cryptocurrency you bought, the price you paid per unit, the price you plan to sell (or already sold) per unit, and the fee rate you pay on each transaction. It instantly shows the net profit in USD and the return on investment as a percentage. Why it matters – Knowing exact profit and ROI helps you decide whether a trade was worthwhile, compare strategies, and plan tax reporting. How to read – The profit line is the cash you keep after fees; a positive number means you made money, negative means a loss. The ROI shows profit relative to the amount you originally invested, so 20% means you earned 20 cents for every dollar spent.
Pro tips
- Enter the fee rate as a decimal (0.001 = 0.1%) not as a percent.
- Round profit and ROI to two decimal places for easier reading.
- Enter the buy price before the sell price; swapping them will flip profit sign.
- Remember fees apply on both buy and sell, effectively doubling the fee impact.
Real-life examples
- A day trader checks if today’s BTC swing covered exchange fees and yielded profit.
- A long‑term holder calculates net gain on ETH sold after a year.
- A tax accountant estimates a client’s crypto ROI for a quarterly report.
Case study
Jane bought 2.5 ETH at $1,800 each, paid a 0.002 fee, and sold at $2,200. Using the calculator she saw a $950 profit and a 21% ROI, confirming the trade covered fees and met her target. Without the tool she would have guessed and risked a loss.
