BullPnL vs ROE
PnL (profit and loss) is the amount in USDT you gain or lose. ROE (return on equity) is that amount as a percentage of the margin you used. With leverage, ROE grows much faster than the price move: a 5% price move at 10x leverage is about a 50% ROE, before fees.
How to use it
- Pick Long if you profit when the price goes up, Short if you profit when it goes down.
- Enter the margin you put into the trade and your leverage.
- Enter the entry price and the price you closed or plan to close at.
Formula
Example
You open a long with 100 USDT margin at 10x, so the position is 1,000 USDT. Entry is 60,000 and you close at 63,000, a 5% move. PnL = 3,000 x 0.016667 = +50 USDT and ROE = 50 / 100 = +50%. The same move against a short would be a 50 USDT loss.
What this calculator leaves out
Exchanges also charge trading fees on open and close, and funding payments every few hours. On short trades these are small, but on high leverage they eat a real part of the ROE. Use the fee calculator and the funding fee calculator to see the full cost.
Frequently asked questions
Why is my ROE so much bigger than the price change?
ROE is measured against your margin, not the full position. With 10x leverage, every 1% price move is about 10% of your margin.
Does this include fees?
No. The result is gross PnL. Subtract trading fees and funding for the net result.
Is PnL calculated the same on all exchanges?
For USDT-margined linear contracts, yes. Coin-margined (inverse) contracts use a different formula.
