Crypto Profit Calculator
Net profit or loss on a crypto buy-sell pair after fees
Calculate crypto profit or loss after fees. Net gain, ROI percentage, and total fee drag. Enter units owned and buy price to see net gain after fees.
What this tool does
This calculator estimates your net profit or loss when buying and selling a cryptocurrency position, accounting for exchange fees applied to both the purchase and sale. Enter the number of units, the price per unit at entry and exit, and the fee percentage charged by your exchange on each transaction. The tool calculates your total profit or loss in local terms, your return on investment as a percentage, and shows the cumulative fee drag across both sides of the trade. The result represents the actual proceeds remaining after all fees are deducted from your sale proceeds and added to your cost basis. Exchange fees on the buy side and sell side have the largest impact on final outcome. A typical scenario is verifying whether a completed trade matched your pre-trade expectations, or modelling different exit prices before entering a position. The calculator assumes fees are a flat percentage and doesn't account for taxes, trading spreads, or price slippage.
Quick answer: with the default values, the result is $7,312.50 (Net Profit). Adjust the values below for your own figures.

How Fees Eat Into Crypto Gains
Major crypto exchanges charge 0.1-1.5 percent per trade. A round-trip (buy then sell) means paying the fee twice on different amounts. A 0.5 percent fee on each side eats approximately 1 percent of the total trade value — meaningful for active traders, less so for long-term holders.
The Simple Math Behind Big Numbers
Net profit equals (sell price times units) minus (buy price times units) minus total fees. Most exchanges show gross numbers on trade history; this calculator strips fees to show true economic profit. The net (after-fee) figure is the one typically used for tax reporting, rather than the gross.
A worked example
With the defaults: units owned of 0.5, buy price per unit of 30,000, sell price per unit of 45,000, fee of 0.5. The tool returns 7,312.50.
What moves the number most
The result responds to Units Owned, Buy Price per Unit, Sell Price per Unit, and Fee % (each side).
The formula behind this
Net profit is (units times sell price) minus (units times buy price) minus fees on both the buy side and sell side. Fee is applied to the full notional of each leg. ROI is net profit divided by buy-side investment.
Where this fits in planning
This is a "what-if" tool, not a forecast. It helps to test ideas: what happens if one of the inputs comes in higher or lower than you first assumed. The value is in the scenarios you run, not the single answer you get from the defaults.
Crypto P&L estimate indicates $7,312.50 net profit or loss after fees.

Sources & Methodology
Methodology
This calculator computes net profit or loss by taking the total sale proceeds, subtracting the total purchase cost, and deducting transaction fees applied to both sides of the trade. Specifically, it multiplies units owned by the difference between sell price and buy price, then subtracts fees calculated as a percentage of the full notional value on entry and exit. The model assumes a flat fee rate applied uniformly to both buy and sell transactions, treats all units as purchased at a single price point, and does not account for variable fee structures, exchange-specific pricing tiers, or taxes. Return on investment is expressed as net profit divided by the initial buy-side investment. Results reflect the stated fee percentages and prices only; actual outcomes may differ based on market conditions and platform-specific fee schedules at execution.
