PnL calculator
Enter your entry, your exit and the size of the position to see the profit or loss after fees, and what it means for the margin you posted.
Profit and loss calculator
EstimateThe example is a $10,000 long on Bitcoin at ten times, in at $60,000 and out at $62,400. Change any number.

Funding payments are not included: they come out of an open position every few hours. The live funding rates show what each side is paying now.
How it works
Example: a $10,000 long from $60,000 to $62,400, a 4% move. That is 0.1667 BTC, so the gain before fees is $400. At 0.05% a side the fees are 0.05% of $10,000 plus 0.05% of $10,400, or $10.20, which leaves $389.80. At 10x the margin was $1,000, so the return on margin is 39.0%.
Why the return on margin looks so big
Leverage doesn't change the dollar result: the position size does. It changes how much margin you post, so the same $389.80 is 3.9% of an unleveraged $10,000 but 39% of $1,000 of margin. It works the same way down. The same 4% move against that long loses $409.80, or 41% of the margin, which is why the calculator always shows the move the other way too.
Fees add up
A taker fee of 0.05% a side costs about 0.1% of the position for a trade in and out: $10 on $10,000. Twenty trades like that cost $200 before a single one has worked. Limit orders that rest on the book usually pay a lower maker fee. Funding is extra while a position stays open: the break-even calculator adds it in, and the live funding rates show what each side is paying now.
Common questions
What is ROE?
Return on equity, here the profit or loss divided by the margin you posted. It is the percentage most exchanges show on an open futures position, and the reason a small price move can look like a huge gain or loss.
Does leverage change my profit?
Not for the same position size. A $10,000 position makes or loses the same dollars at 2x or 20x. Leverage changes the margin you post and how close liquidation sits, so it changes the return on margin, not the dollar result.
How do I measure a trade in R instead?
Divide the result by what you risked at the stop. The risk reward calculator plans it before the trade, and the trading journal works out the R of every closed trade.
