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 per unit to size protocol returns.

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.

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. Record the net figure for tax reporting, not the gross.

A worked example

Try 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. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to Units Owned, Buy Price per Unit, Sell Price per Unit, and Fee % (each side). Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.

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. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.

Where this fits in planning

This is a "what-if" tool, not a forecast. Use it to test ideas before committing: what happens if the rate is 2% lower than hoped, what happens if you add five more years. The value is in the scenarios you run, not the single answer you get from the defaults.

What this doesn't capture

Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. The number represents one scenario rather than a forecast.

Example Scenario

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.

Frequently Asked Questions

Do exchanges show net or gross profit?
Most show gross per trade. P&L reports on the dashboard sometimes include fees, sometimes don't — check the specific exchange. For tax purposes, net (after-fee) numbers are what matter.
What about slippage?
Slippage is the difference between expected and executed price — not modeled here. For market orders on illiquid tokens, slippage can be 1-5 percent and should be subtracted from sell price manually.
Does the fee percentage apply to both buy and sell?
Yes — most exchanges charge on both sides. Enter the single-side fee; the calculator applies it to both legs automatically.
What if I haven't sold yet?
Enter the current market price as the sell price to see unrealized profit. This is not a taxable event until actually sold but is useful for portfolio tracking.
