What is PnL in crypto futures trading?

PnL (Profit and Loss) is the dollar amount you gain or lose on a futures trade. For a long position: PnL = (Exit Price − Entry Price) × Quantity. For a short position: PnL = (Entry Price − Exit Price) × Quantity. PnL does not include trading fees unless you enable fee calculation in Advanced mode.

What is ROE and how is it different from PnL?

ROE (Return on Equity) measures your profit relative to the margin (collateral) you posted, not the full position size. Formula: ROE = PnL / Margin × 100%. With 10× leverage, a 1% price move creates a 10% ROE. PnL is in dollars; ROE is a percentage of your actual capital at risk.

Does leverage affect my profit or loss?

Leverage does not change your dollar PnL — that depends only on position size and price movement. However, leverage affects ROE and margin. Higher leverage means less margin is required, so the same dollar profit represents a higher percentage return. It also means a smaller adverse move can liquidate your position.

What is the break-even price?

The break-even price is the exit price where your PnL equals zero. Without fees, it equals your entry price. When trading fees are enabled, the break-even shifts slightly: for a long, it moves above entry; for a short, it moves below entry. With a typical 0.05% taker fee, break-even shifts by roughly 0.1% from entry.

What is the difference between isolated and cross margin?

In isolated margin, only the margin allocated to a specific position is at risk. If liquidated, you lose only that margin. In cross margin, your entire wallet balance acts as collateral. This pushes the liquidation price further away, but if liquidated, you can lose the whole balance. Most beginners start with isolated margin for better risk control.

How to Use the PnL / ROE Calculator

This calculator helps you estimate profit or loss, return on equity, and liquidation risk for a crypto futures position before you open a trade.

Input Fields

Pair (COIN/USDT): The trading pair, e.g. BTCUSDT. Start typing to search across 500+ coins on the selected exchange.
Exchange: Choose one of the supported exchanges: Binance, Bybit, OKX, KuCoin, Bitget, Gate.io, MEXC, HTX. The Last button fetches the current market price automatically.
Entry / Exit: Entry — the price at which you open the position.
Exit — the price at which you plan to close it.
Example: Entry = $65,000, Exit = $66,000 means you expect BTC to rise by $1,000.
Side: Long / Short: Long — you profit when the price goes up.
Short — you profit when the price goes down.
Example: Long at $65,000 → exit $66,000 = profit. Short at $65,000 → exit $64,000 = profit.
Quantity (coin) / Amount (USDT): These two fields are linked. Type in one and the other updates automatically.
Quantity = how many coins (e.g. 0.1 BTC).
Amount = notional value in USDT (e.g. $6,500).
Formula: Amount = Quantity × Entry price.
Leverage (1–200×): The multiplier applied to your margin. Higher leverage = less margin needed, but higher risk.
Example: $6,500 position with 10× leverage → only $650 margin required.

Output Fields

PnL (Profit & Loss): Your dollar profit or loss on the trade.
Formula: (Exit − Entry) × Quantity for long; inverted for short.
Example: Long 0.1 BTC, Entry $65,000, Exit $66,000 → PnL = $100.
ROE (Return on Equity): Percentage return on your margin (collateral), not on the full position.
Formula: PnL / Margin × 100%.
Example: PnL = $100, Margin = $650 → ROE = 15.38%.
Margin Used: The collateral locked by the exchange to open this trade.
Formula: Entry × Quantity / Leverage.
Example: $65,000 × 0.1 / 10 = $650.
Break-even: The exit price where PnL = 0 (accounting for fees if enabled).
Without fees, break-even equals entry price. With 0.05% taker fee, it shifts slightly to cover open + close costs.

Advanced Mode

Switch to Advanced to unlock extra inputs and three result tabs:

Margin Mode: Isolated / Cross: Isolated — only the position margin is at risk. If liquidated, you lose the margin only.
Cross — your entire wallet balance acts as margin. Lower liquidation risk, but the whole balance is exposed.
Include Fees: Toggle to factor in exchange trading fees (taker rate). Fetch fees pulls the current rate automatically. Typical taker fee: 0.04%–0.06%.
Mark Price: The fair price calculated by the exchange. Used for liquidation and funding calculations. Usually close to the last traded price, but more stable.
Risk Tab: Shows Notional (total position value), ΔPnL/1% (how much PnL changes per 1% price move), and ΔPnL/$1 (PnL change per $1 move).
Liquidity Tab: Shows the estimated liquidation price and distance to liquidation from the mark price. Helps gauge how much room you have before the exchange closes your position.

Quick Example

You want to go Long BTC at $65,000, planning to close at $66,000. You use 0.1 BTC ($6,500 notional) with 10× leverage.

Margin = $650 • PnL = +$100 • ROE = +15.38%
If price drops instead → Exit $64,000 → PnL = −$100, ROE = −15.38%.
