How does this estimate work?
Profit and loss (P&L) compares the value received when an asset is sold with the original purchase cost. This calculator uses the quantity and prices you enter. Gross purchase cost is entry price multiplied by quantity; gross sale proceeds are exit price multiplied by quantity. The estimated net result is sale proceeds minus exit fee, less purchase cost and entry fee. Return percentage divides that net result by total cost including the entry fee.
For example, imagine a purely hypothetical purchase of 2 units at 100 currency units each and a sale at 120, with no fees. Gross proceeds are 240, cost is 200, and the modeled gain is 40, or 20%. This example is arithmetic only and does not describe a real asset or expected outcome. Enter fees in the same currency as the prices. The calculator treats fees as flat amounts and does not model percentage fees, spreads, slippage, deposits, withdrawals, staking rewards, or currency conversion.
A result is an estimate based on the inputs, not an account statement or tax calculation. It does not identify the applicable cost-basis method, holding period, or jurisdiction-specific treatment. For a partial sale, enter only the quantity sold and the relevant allocated purchase cost is approximated using the entry price you supply. Check your exchange records and applicable rules before relying on a calculation.
To compare scenarios, change one input at a time and note how fees affect the break-even point. With positive fees, the exit price generally needs to exceed the entry price before the modeled position shows a net gain. The size of that difference depends on quantity and fee amounts. The calculator simply reports the arithmetic implied by the values entered.
Frequently asked questions
Does this include trading fees?
Yes. You can enter flat entry and exit fees in the same currency as the prices. Percentage-based fees must be calculated separately and entered as amounts.
Is this a tax estimate?
No. The result is a simple position calculation and does not determine taxable gain, cost-basis method, or tax owed.
Can I use it for a loss?
Yes. When modeled proceeds after fees are below modeled cost including fees, the result is negative.
