How profit and loss is calculated
For a long, gross P/L is (exit − entry) × quantity; a short is the reverse. Subtract entry and exit fees and funding to get net P/L. For leveraged trades, return is net P/L ÷ margin, so a 1% price move is roughly a 10% move on margin at 10x.
How to use it
- Pick spot or futures and the side. Spot has no leverage.
- Enter entry and exit (or target) prices.
- Enter your capital either as margin or directly as quantity. With margin, quantity = margin × leverage ÷ entry.
- Fees are per side, applied at entry and again at exit. Enter funding/interest as a total percentage of notional.
Price needed for a target return
To make 50% on margin, the required move is (target% ÷ leverage + round-trip fees). Higher leverage means a smaller move reaches the target — and a smaller adverse move erodes your margin just as quickly.
Caveats
Fee rates and funding vary by exchange, tier and order type. Results are estimates and can differ from your actual fills.
FAQ
What is the difference between return on margin and price move?
Price move is relative to entry; return on margin is relative to your own capital. In futures the latter scales with leverage.
Can I enter capital instead of quantity?
Yes. Choose margin and the quantity is derived as margin × leverage ÷ entry.
How is a short calculated?
A falling price is profit and a rising price is loss. Select Short and the sign flips.
Where does funding go?
Enter the total funding/interest paid (or received) while holding, as a % of notional; it is deducted from net P/L.
