Futures PnL vs ROE: Why Your Profit Percentage Looks So Big

BullCalc Team · October 11, 2026 · 3 min read

Open a futures position, watch the price move 2% in your favour, and the exchange may show a 40% gain. It feels great, but it is easy to misread. To understand your results you need to know the difference between PnL and ROE.

PnL: the money

PnL stands for profit and loss. It is the actual amount in USDT that you gained or lost. For a USDT-margined contract it is calculated from the full position size: the price change times the quantity of coins in the position.

If you hold a 2,000 USDT long and the price rises 2%, your PnL is about 40 USDT, no matter how much leverage you used.

ROE: the percentage on your margin

ROE means return on equity. It divides the PnL by the margin you put up. The same 40 USDT profit is:

20% ROE with 200 USDT margin (10x leverage)
40% ROE with 100 USDT margin (20x leverage)
2% ROE with 2,000 USDT margin (1x leverage)

The profit in your pocket is identical in every case. Only the percentage changes, because the base it is measured against changes.

Why ROE can mislead you

ROE makes high leverage look attractive because winners show huge percentages. But the account does not care about ROE, it cares about USDT. A trader who brags about a 300% ROE may have made that on a tiny margin while risking far more of the account through tight liquidation levels.

A better way to judge a trade is to compare the PnL to your whole account, or to the amount you risked. Making 40 USDT on a trade where you risked 20 USDT is a 2R winner. That number tells you much more than "40% ROE".

The quick formulas

PnL (long) = (Exit - Entry) x Quantity PnL (short) = (Entry - Exit) x Quantity ROE = PnL / Margin x 100 ROE = Price change % x Leverage (roughly, before fees)

You can check any trade with the futures PnL calculator.

Don't forget the costs

Exchanges show unrealised PnL before closing fees. When you close, you pay another fee on the full position size, and if you held through funding times you may have paid or received funding. On a high leverage trade with a small move, these costs can remove a big part of the ROE you saw on screen.

Key takeaways

PnL is real money. ROE is a percentage of margin.
Leverage changes ROE, not PnL, for the same position size.
Judge trades by PnL relative to your account and to your risk.
