Trade math estimate
The calculator turns your buy and sell prices into profit, loss, ROI, and break-even using clear formulas.
Fee aware
Buy and sell fees are subtracted explicitly, so ROI and break-even reflect what reaches your wallet.
Estimate only
No live prices are fetched. Use any prices you like, including hypothetical exits.
Action focused
Compare scenarios for higher prices, lower prices, and break-even to plan exits.
Crypto basics
What is a crypto profit calculator?
A crypto profit calculator turns the buy and sell sides of a trade into a single, comparable number. You enter quantity, prices, fees, and any one-off costs, and it returns profit, ROI, fees paid, and the break-even price. It is an educational tool for understanding trades, not a market feed and not investment advice.
How it works
How crypto profit is calculated
Gross cost and value
Gross cost is quantity × buy price. Gross value is quantity × sell price.
Fees applied
Percentage fees scale with trade size; fixed fees are flat amounts. Both reduce net return.
Profit before tax
Net proceeds minus total cost basis. Total cost basis includes the buy fee and any additional costs.
ROI percentage
Profit divided by total cost basis, expressed as a percentage. Useful for comparing trades of different sizes.
Formula
Crypto ROI formula
Gross cost
Gross Cost = Quantity × Buy PriceThe starting outlay before fees.
Total cost basis
Cost Basis = Gross Cost + Buy Fee + CostsIncludes everything you paid to acquire and hold the position.
Net proceeds
Net Proceeds = Quantity × Sell Price − Sell FeeWhat you actually receive when you exit.
Profit before tax
Profit = Net Proceeds − Cost BasisPositive is a gain, negative is a loss.
ROI
ROI % = (Profit ÷ Cost Basis) × 100Return relative to what you invested.
Break-even (percentage fees)
Break-even = Cost Basis ÷ (Qty × (1 − Sell Fee%))Sell price per unit needed to cover the full cost basis after percentage sell fees.
Fees
How trading fees affect profit
Fees enter the math twice. The buy fee raises your effective cost basis, while the sell fee reduces your proceeds. On small trades, fees can swallow most of the gain, which is why break-even is usually higher than the buy price even when the market looks flat.
Break-even
Break-even price explained
Break-even is the sell price that exactly recovers your total cost basis after the sell fee. Selling above break-even produces a profit; selling below it produces a loss, even if the sell price is still above the buy price. Watching break-even instead of the buy price is the simplest way to plan exits.
Tax
Profit before tax vs after tax
Profit before tax
The trade math result based on prices and fees. Use this to compare trades.
Profit after tax
The optional tax rate is applied only when profit is positive. Real tax rules vary by jurisdiction and holding period.
Caveats
Limitations of this estimate
No live prices
Prices entered are the only source of truth. The calculator does not connect to any exchange.
Slippage and spreads
Real trades often fill at slightly different prices than expected. Use additional costs to model that.
Not advice
This calculator is educational. Crypto is volatile and past performance does not predict future results.
Tax simplification
The optional tax estimate is a single rate applied to the entire profit, which is not how real tax codes work.
FAQ
Crypto profit calculator questions
Multiply your quantity by the sell price to get gross proceeds, subtract sell fees, and compare with your total cost basis (buy price × quantity + buy fee + additional costs). The difference is your profit or loss before tax.
