How to Calculate Futures PnL to Avoid Misreading

The profit figures shown on futures screen are not necessarily the same as the profits that actually go into the balance.

Differences may arise because the platform displays unrealized PnL, while opening costs, closing costs, and funding fees have not been fully accounted for.

Understanding how to calculate PnL in futures helps traders differentiate between gross profit, net profit, and the percentage of profit to margin.

This ability is also important so that high leverage does not create the impression that the strategy generates greater profits than it actually does.

Key Takeaways

• PnL of long and short positions is calculated with different price difference directions.
• Leverage does not change the nominal PnL if the position size remains fixed, but it affects margin, ROI, and liquidation risk.
• Net PnL is only known after trading costs, funding fees, and other costs are taken into account.

What is PnL in Futures Trading?

 

PnL is an abbreviation of profit and loss, namely profit or loss resulting from changes in the price of a position.

In PnL futures trading, returns do not only depend on price increases as traders can also profit from short positions when prices fall.

There are two types of PnL that need to be distinguished.

Unrealized PnLis the floating profit or loss while the position is still open.

Realized PnLappears when the position is closed in whole or in part and has taken into account the cost components according to the platform mechanism.

This difference explains why the profit seen before a position is closed can be greater than the change in balance after the transaction is completed.

Futures PnL Formula for Long and Short Positions

For USDT-margined linear contracts, the simple PnL futures formula is as follows:

Long position:

PnL = (Exit price − Entry price) × Position size

Short position:

PnL = (Entry price − Exit price) × Position size

Long positions profit when the price rises above the entry price.

Conversely, a short position makes a profit when the price falls below the entry price.

The actual formula may include a contract multiplier, depending on the product specifications used by the platform.

Inverse contracts like BTC-margined futures use a different formula because their profits and losses are calculated in the underlying asset.

Traders need to check the contract type before making crypto futures calculations.

Example of Calculating Futures Profit on a Long Position

A trader opens a long BTC/USDT position of 0.2 BTC at US$27,000. The position is then closed at US$27,500.

The calculation:

(US$27.500 − US$27.000) × 0,2 BTC = US$100

Therefore, the gross profit on the position is US$100. This figure isn't necessarily net profit, as opening, closing, and funding fees haven't been deducted. BingX uses a similar calculation example to explain the unrealized P&L on long positions.

If the price actually drops to US$26,500, the calculation becomes:

(US$26.500 − US$27.000) × 0,2 BTC = −US$100

A negative result indicates a floating loss of US$100.

How to Calculate Short Position Losses and Profits

For example, a trader opens a short position of 0.3 BTC at US$26,000 and closes it at US$25,000.

(US$26.000 − US$25.000) × 0,3 BTC = US$300

The trader earned a gross profit of US$300 because the price moved down in the direction of his position. If the total trading and funding costs were US$10, the realized PnL would be US$290.

If the short position is closed at US$27,000, the result changes to:

(US$26.000 − US$27.000) × 0,3 BTC = −US$300

This example shows that the PnL of long and short positions use opposite subtraction directions.

Why is Unrealized PnL Different from Net Profit?

Unrealized PnL generally only reflects the change in position value based on the entry price and the current reference price.

This figure does not include all costs incurred while the position is open.

The simple formula for realized PnL is:

Net PnL = Gross PnL − trading costs ± funding fees − other costs

Funding fees can be either an expense or an income, depending on the funding rate and position direction. Trading costs typically arise when opening and closing positions, so traders need to account for both.

Unrealized PnL can be displayed separately from costs, while realized PnL includes the PnL of closed positions, trading costs, and funding costs.

Mark Price or Last Price, Which is Used?

Futures platforms can usemark price or last priceas a reference for PnL display.

The last price is the most recent transaction price, while the mark price is designed as a more stable reference price to reduce distortions caused by thin transactions or momentary movements.

Mark price is used to calculate unrealized PnL and the liquidation process.

This allows users to view PnL based on last price or mark price.

Since the reference price may differ, the PnL calculated manually using the latest price may not be exactly the same as the figure in the application.

Does Leverage Change the Size of PnL?

Leverage doesn't directly change the nominal P&L as long as the position size and price movement remain the same. Leverage determines the margin required to control the position.

In the example of a US$5,400 position, 5x leverage requires an initial margin of approximately US$1,080. A US$100 profit equates to an ROI of approximately 9.26% before costs.

If the leverage is increased to 10x while the position size remains at US$5,400, the margin drops to approximately US$540.

The nominal profit is still US$100, but the ROI increases to around 18.52% because the divisor is smaller.

An increase in ROI due to leverage does not mean that the nominal PnL automatically increases.

Problems arise when traders use leverage to increase position size.

In such conditions, the potential for profit increases, but losses and the risk of liquidation also increase.

Common Mistakes When Reading Futures Profit Loss

The first mistake is to assume unrealized PnL is guaranteed to be received. Its value can still change as long as the position is not closed.

Another mistake is comparing ROI without considering leverage and margin. High ROI can come from small margins, not from large nominal profits.

Traders also often forget about opening, closing, funding fees, and partial position closure fees.

To obtain an accurate calculation of futures trading profits, all transaction history and costs need to be added up.

Conclusion

The P&L calculation for futures starts with the entry price, the exit price or reference price, the position size, and the long or short direction. This result is still the gross P&L before accounting for costs.

Traders need to differentiate between unrealized PnL, realized PnL, ROI, and actual balance changes. By understanding these components, the profit displayed on the screen is not easily mistaken for net profit.

FAQ

What is the PnL futures formula for long positions?

The basic formula is the exit price minus the entry price, then multiplied by the position size.

What is the PnL futures formula for short positions?

The formula is entry price minus exit price, then multiplied by the position size.

Does 10x leverage make profits 10 times bigger?

Not if the position size remains constant. Leverage reduces the required margin and increases the ROI relative to the margin. Nominal profits increase only when the position size also increases.

Why is the PnL on the screen different from the balance received?

The P&L for open positions typically excludes trading costs, funding fees, and additional fees. The final balance is only visible after the position is closed.

Does mark price affect liquidation?

Yes. Many platforms use the mark price to calculate unrealized P&L, margin ratios, and liquidation risk to minimize reliance on the last transaction price.

How to calculate net profit of futures?

Subtract the gross P&L from the opening fee, closing fee, funding fee paid, and other fees. Add the funding fee if the trader receives one.
