What Is PNL? Profit and Loss Explained

This content is for educational purposes only and does not constitute financial advice or a recommendation to buy or sell any financial instrument. Trading involves risk, including the potential loss of capital. Always conduct your own research before making financial decisions.

PNL (Profit and Loss) measures the financial gain or loss on a trade, investment, or business over a specified period. A positive PNL means you are ahead of where you started; a negative PNL means you are behind. In trading, PNL appears as a real-time figure on your dashboard showing how your open or closed positions are performing. In business, P&L refers to a formal financial document summarizing revenue and expenses.

If you saw the term on a crypto exchange or brokerage app and want to know what that number actually means, you are in the right place. If you encountered "P&L" on a financial report for a business, the section on P&L statements in business is written specifically for you.

What Does PNL Stand For?

PNL is an acronym for Profit and Loss. You will also see it written as P&L or occasionally P/L, depending on the context. The convention in trading and crypto markets is to write it without the ampersand (PNL); in accounting and business finance, the ampersand version (P&L) is standard. Both abbreviations refer to the same underlying concept: the difference between what you gained and what you lost.

Convention note: Throughout this article, "PNL" refers to the trading context. "P&L" refers to the business accounting context. The two are not interchangeable. They have different formulas, different audiences, and apply to different situations.

PNL in Trading

On a trading platform, PNL is the real-time number that tells you how much you have gained or lost on an open or closed position. Most crypto exchanges (such as Binance, Bybit, and OKX) display your PNL prominently on the trading dashboard, either next to each open position or as a total across your portfolio.

The number you see has two possible states. If your position is still open, the figure is unrealized PNL, meaning it is a live estimate that changes with every price movement. If you have already closed the position, the figure is realized PNL, meaning the gain or loss is confirmed and has been credited or debited from your account. This distinction is one of the most important concepts in trading, and the full section on realized vs. unrealized PNL explains it with worked examples.

PNL in Business

In a business context, P&L refers to a formal financial document called a profit and loss statement (also known as an income statement). This document summarizes a company's revenues, costs, and operating expenses over an accounting period, typically monthly, quarterly, or annually, to show whether the business made a net profit or a net loss.

If you encountered "P&L" in a financial report rather than on a trading platform, the P&L statement section covers everything you need: what goes on the document, how to read it, and how it differs from a balance sheet.

How to Calculate PNL

The PNL formula has three variables: your entry price, your exit price, and your position size. Understanding each one before applying the formula prevents the most common calculation errors.

The Formula Variables

Entry price is the price at which you opened (entered) the position. Think of it as the price you paid for an asset: your profit or loss depends entirely on how that price compares to what you later sell it for. If you have added to a position over time at different prices (a practice sometimes called dollar-cost averaging), your exchange calculates a weighted average entry price automatically.

Position size is the number of units you hold: the number of coins, shares, or contracts in the trade. PNL scales directly with position size. A $1,000 price move on a position of 1 BTC produces a $1,000 PNL; the same $1,000 move on a position of 10 BTC produces a $10,000 PNL. This is why the dollar figure on your dashboard can look large or small relative to what seems like a modest price movement.

A long position is the standard orientation most beginners encounter first: you buy an asset expecting the price to rise, and your PNL is positive when it does.

Long Position PNL

PNL = (Exit Price - Entry Price) x Position Size

• Entry Price = the price at which you opened the position
• Exit Price = the price at which you closed the position
• Position Size = the number of units held

Worked examples, long position:

• Profit scenario: You buy 1 BTC at $30,000 and sell at $34,000. PNL = ($34,000 - $30,000) x 1 = +$4,000
• Loss scenario: You buy 1 BTC at $30,000 and sell at $27,000. PNL = ($27,000 - $30,000) x 1 = -$3,000
• Stock example: You buy 10 shares at $50 and sell at $65. PNL = ($65 - $50) x 10 = +$150

Short Position PNL

A short position profits when price falls, which means the PNL formula reverses direction. Where a long position gains when the exit price exceeds the entry price, a short position gains when the exit price is below the entry price. The subtraction simply flips.

Short Position PNL

PNL = (Entry Price - Exit Price) x Position Size

Note: The subtraction is reversed because a short position profits when price falls.

Worked examples, short position:

• Profit scenario: You short 1 BTC at $30,000. The price falls to $27,000. PNL = ($30,000 - $27,000) x 1 = +$3,000
• Loss scenario: You short 1 BTC at $30,000. The price rises to $33,000. PNL = ($30,000 - $33,000) x 1 = -$3,000

Short selling in traditional stock markets involves borrowing shares before selling them, which is mechanically different from shorting a crypto perpetual contract (where the exchange handles the process through funding rates). The PNL formula applies the same way conceptually in both cases.

PNL vs. ROI: What Is the Difference?

PNL and ROI (Return on Investment) measure performance differently. PNL gives you a dollar figure showing the absolute gain or loss. ROI gives you a percentage showing the return relative to the amount you invested.

ROI Formula

ROI = (Net Profit / Initial Investment) x 100

Consider this example: you invest $1,000 and earn $200. Your PNL is +$200. Your ROI is +20%.

Both figures describe the same trade, but they answer different questions. The table below shows when each metric is more useful:

A $200 profit on a $1,000 investment is far more efficient than a $200 profit on a $10,000 investment. ROI captures that distinction where raw PNL does not.

Realized vs. Unrealized PNL: What Is the Difference?

The difference between realized and unrealized PNL comes down to one thing: whether or not you have closed your position.

Realized PNL

Realized PNL (also called closed PNL on some exchange dashboards) is the confirmed profit or loss that locks in when you close a position. Before you close, any gain or loss is a floating estimate. The moment you sell, the number becomes permanent.

Worked example: You buy 1 ETH at $2,000. Later you sell at $2,500. Your realized PNL is ($2,500 - $2,000) x 1 = +$500. That $500 is credited to your account balance and cannot change.

Realized PNL is the figure that directly affects your account balance. A stop-loss order converts your unrealized loss into realized PNL at a controlled price level, capping the damage before it grows further. A take-profit order converts unrealized PNL into realized PNL at your chosen profit target, locking in gains automatically.

Realized PNL may have tax implications in your jurisdiction. In most countries, confirmed trading gains are treated as taxable income or capital gains. Consult a tax professional for guidance specific to your situation and country.

Unrealized PNL

Unrealized PNL (also called floating PNL or open PNL, sometimes referred to as a paper profit or paper loss) is the live estimate of your gain or loss on a position you have not yet closed. It updates continuously as the market price moves, which is why the number on your dashboard keeps changing.

Worked example: You buy 1 BTC at $30,000. The current market price is $28,000. Your unrealized PNL is ($28,000 - $30,000) x 1 = -$2,000. Nothing is permanently lost at this point, because you have not sold. Once the price recovers to $30,000 or above, the unrealized PNL returns to zero or turns positive.

Key distinction: Unrealized PNL becomes realized PNL the moment you close your position. Until then, it is an estimate, not a confirmed gain or loss.

Why is my PNL negative? A negative PNL on an open position means the current market price has moved against your entry price. For a long position, the price has fallen below where you bought. For a short position, the price has risen above where you entered. A negative unrealized PNL is not a permanent loss. It only locks in if you close the position at that price.

Why does my PNL keep changing? Because it is unrealized. Every price tick in the market updates the calculation in real time. This is normal behaviour, not an error on your platform.

Mark Price vs. Last Traded Price

Exchanges do not use the last traded price to calculate your live unrealized PNL. They use the mark price: a fair-value estimate derived from multiple exchange price feeds across the broader market. This system prevents temporary price spikes on a single exchange from triggering artificial liquidations and gives a more accurate picture of what your position is actually worth.

This is why your PNL dashboard may show a slightly different number than you would calculate by hand using the visible ticker price. The discrepancy is not an error; it reflects the difference between the mark price and the last traded price. For readers who want the technical detail on how mark prices are calculated for perpetual contracts, the mark price calculation guide covers the methodology in full.

Realized vs. Unrealized PNL at a Glance

Common PNL Mistakes to Avoid

The most common PNL mistake beginners make is treating unrealized PNL as money they have already earned. An unrealized gain of $500 on an open position is not $500 in your account. It is a snapshot of a number that will change before you close. Acting on it (withdrawing, reinvesting, or spending) before the position closes is premature.

Panic-closing a position because of a negative unrealized PNL is also worth examining closely. A temporary move against your position does not necessarily mean the trade is wrong. The price may simply not have moved in your direction yet, and closing early converts a floating loss into a permanent one.

Calculating PNL manually using the ticker price rather than the mark price leads to a different number than the dashboard shows. As covered in the section above, that discrepancy is intentional. The exchange uses the mark price specifically to reflect fair market value.

Evaluating a trade's profitability using gross PNL, without deducting trading fees, produces an inflated picture of actual results. The next section explains exactly how fees affect the final figure.

How Leverage and Fees Affect Your PNL

Two factors reduce or amplify the PNL you see on your dashboard beyond the basic formula: leverage and trading fees. Both are absent from most PNL explainers, which is why traders applying the standard formula often get a different number than their platform shows.

How Leverage Amplifies Your PNL

Leverage is borrowed capital that allows you to open a position larger than your available funds would otherwise cover. Margin (the capital you deposit as collateral for a leveraged trade) is the amount you actually put in. The exchange supplies the rest.

PNL is calculated on the full notional position value, not just your margin. This is the core mechanic that makes leverage amplify gains and losses equally.

Leveraged PNL

Notional Position Value = Margin x Leverage

PNL = Price Change (%) x Notional Position Value

Example: $1,000 margin x 10x leverage = $10,000 notional position

• A 5% price increase: PNL = +$500 (a 50% return on your $1,000 margin)
• A 5% price decrease: PNL = -$500 (a 50% loss on your $1,000 margin)

The same 5% market move that would produce a $50 gain on an unleveraged $1,000 position produces a $500 gain on a 10x leveraged position of the same margin. The math works identically in the other direction.

Margin trading is the broader practice of trading with borrowed exchange funds. In margin trading, PNL tracks the full notional value of the position, which is why the dollar figures on a futures dashboard can look large relative to the amount you deposited.

Liquidation is the forced closure of a leveraged position that occurs when unrealized losses approach the value of the margin you deposited. When your negative unrealized PNL reaches or exceeds your margin balance, the exchange closes the position automatically to prevent further loss. That unrealized loss then becomes a confirmed realized loss. A stop-loss order placed well above the liquidation price is the standard tool for preventing this outcome.

⚠️ Risk Note: Trading with leverage carries the risk of losing more than your initial deposit on a position. A 10x leveraged position can lose its full margin value on a 10% adverse price move. The examples above are illustrative only and do not represent guaranteed outcomes.

Effective risk management, including disciplined position sizing and stop-loss placement combined with controlled use of borrowed capital, is the primary driver of sustainable long-term PNL.

Futures contracts and perpetual contracts are the instruments where most traders first encounter leveraged PNL in practice. A futures contract obligates you to buy or sell an asset at a future date. A perpetual contract (a type of crypto futures contract with no expiry date, unique to crypto exchanges) works similarly but has no settlement deadline. In both instruments, PNL is tracked in real time and updated using the mark price continuously.

How Trading Fees Reduce Your Net PNL

The PNL figure on most exchange dashboards is gross PNL: it does not deduct the trading fees you paid to open and close the position. Your actual take-home result is your net PNL, which subtracts those fees from the gross figure.

Net PNL

Net PNL = Gross PNL - Entry Fee - Exit Fee

Example: Gross PNL = +$100 | Entry fee = $7.50 | Exit fee = $7.50

Net PNL = $100 - $7.50 - $7.50 = +$85

Trading platforms typically charge two types of fees: maker fees (paid when you place a limit order that adds liquidity to the order book) and taker fees (paid when you place a market order that removes liquidity). Taker fees are generally higher. In perpetual contract trading, a third cost called a funding rate (a periodic payment between long and short traders) also affects your net PNL on positions held overnight or across funding intervals.

A trade that looks profitable on gross PNL can be marginal or even unprofitable once fees are included. For traders who open and close positions frequently, reducing fees through volume-based discount tiers or fee discount tokens can meaningfully improve net PNL over time.

What Is a P&L Statement in Business?

A P&L statement (also called an income statement or profit and loss statement) is a formal financial document that summarizes a company's revenues, operational costs, and net result over an accounting period to show whether the business made a profit or a loss. Unlike trading PNL, which updates in real time, a business P&L statement is prepared periodically: monthly, quarterly, or annually.

A P&L statement starts with total revenue (all money earned from sales or services) and subtracts total expenses (the costs incurred to run the business) to arrive at net profit or net loss. The document shows this calculation in layers, which gives a more detailed picture than a single profit or loss figure.

The Six Components of a Business P&L Statement

1. Revenue / Sales: the total income earned from selling goods or services before any costs are deducted
2. Cost of Goods Sold (COGS): the direct costs of producing the goods or services sold (raw materials, manufacturing labour, direct production costs)
3. Gross Profit: Revenue minus Cost of Goods Sold; what remains after covering production costs directly (Gross Profit = Revenue - COGS)
4. Operating Expenses: the indirect costs of running the business day to day, including rent, staff salaries, utilities, and marketing spend
5. Operating Income: Gross Profit minus Operating Expenses; this figure (also called Earnings Before Interest and Taxes) shows profitability from core operations before financing costs
6. Net Profit (or Net Loss): the bottom line after all remaining deductions including taxes and interest; the final measure of whether the business made or lost money during the period

A Simple Business P&L Example

In this example, the business generated $500,000 in revenue but ended with $110,000 in net profit after all costs. Gross profit ($300,000) shows the margin on the products or services sold. Operating income ($150,000) shows what remains after running the business. Net profit ($110,000) is what actually belongs to the business owners at the end of the period.

P&L Statement vs. Balance Sheet

A P&L statement and a balance sheet answer different questions about a business's finances. A P&L statement shows financial performance over a period of time: it tracks income and expenses, along with the resulting profit or loss. A balance sheet shows financial position at a single point in time: it lists what the business owns (assets), what it owes (liabilities), and the remaining equity.

The two documents work together. The P&L tells you whether the business is generating profit. The balance sheet tells you whether it is financially sound. A business can be profitable on its P&L and still face cash flow problems visible on the balance sheet.

How to Improve Your Trading PNL

There is no universal "good" PNL figure. A $100 profit on a $500 position is a 20% return; the same $100 on a $10,000 position is 1%. What matters is whether your gains consistently outpace your losses after accounting for fees and risk.

The five strategies below address the most common and controllable drivers of trading PNL.

1. Set a stop-loss on every position. A stop-loss order closes your position automatically at a pre-set price, converting unrealized loss into realized loss at a controlled level before it can grow further. Setting a stop-loss before you open a position defines your maximum acceptable loss for that trade. For a practical guide to placing stop-loss orders, see how stop-loss and take-profit orders work in spot trading.

2. Use take-profit orders to lock in gains. A take-profit order converts unrealized PNL into realized PNL at your chosen profit level, capturing gains without requiring you to watch the position manually. Pairing a take-profit with a stop-loss defines both the upside you are targeting and the downside you will accept before entering. For futures and perpetual contracts specifically, take-profit and stop-loss in perpetual futures contracts explains the mechanics in detail.

3. Calculate net PNL before judging a trade. Always subtract your entry and exit fees from your gross PNL before evaluating whether a trade was profitable. A position showing +$20 gross PNL with $15 in fees produced only +$5 in actual value. Traders who consistently ignore fees tend to overestimate their performance and underestimate their costs.

4. Keep borrowed capital proportional to your risk tolerance. Higher leverage amplifies both gains and losses relative to your margin. Traders who size their positions so that a reasonable adverse price move does not trigger liquidation preserve their ability to hold through temporary drawdowns and recover. Reducing the multiplier also reduces the speed at which a negative unrealized PNL approaches the liquidation threshold. To understand exactly how leverage affects your unrealized PNL figure, the relationship between leverage and unrealized P&L explains the calculation directly.

5. Track win rate and risk-reward ratio alongside your PNL. Two metrics that work alongside PNL to evaluate trading strategy quality are win rate (the percentage of trades that close with a positive realized PNL) and risk-reward ratio (the potential profit of a trade relative to its maximum planned loss). A trader with a 40% win rate can still achieve positive cumulative PNL if their average winning trade is significantly larger than their average losing trade. A strategy with a 1:3 risk-reward ratio, risking $100 to target $300, only needs to win 34% of the time to break even.

Tracking PNL across all positions in your portfolio helps you evaluate which trades are performing and where to adjust your allocation, which is the foundation of disciplined portfolio management.

Frequently Asked Questions

What does PNL stand for?

PNL stands for Profit and Loss. It measures the financial gain or loss on a trade, investment, or business over a specified period. A positive PNL means the position gained value relative to where you entered; a negative PNL means it lost value.

Is PNL the same as profit?

PNL is not the same as profit alone. The term covers both directions: a positive PNL is a profit, and a negative PNL is a loss. Using PNL as the standard metric is more useful than "profit" precisely because it acknowledges both outcomes in a single figure.

What is the difference between realized and unrealized PNL?

Realized PNL is locked in after you close a position. It directly changes your account balance and may carry tax implications. Unrealized PNL is the live, floating estimate on an open position. It shifts with every price movement and has no effect on your balance until you close the trade. The simplest test: if the position is still open, the PNL figure you see is unrealized.

Why is my PNL negative?

A negative PNL means the market price has moved against your entry. For a long position, the price dropped below where you bought. For a short position, it rose above where you entered. If the position is still open, the loss is not confirmed. A stop-loss order automatically closes the position at a pre-set price, preventing the negative PNL from growing beyond a level you set in advance.

Does PNL include trading fees?

Most exchange dashboards show gross PNL, which does not deduct trading fees. Your net PNL is gross PNL minus the entry fee and the exit fee combined. On a trade with +$100 gross PNL and $15 in total fees, the net result is +$85. Evaluating trades on gross PNL alone overstates actual profitability.

How does leverage affect PNL?

Leverage amplifies PNL in both directions by calculating gains and losses on the full notional position rather than just the margin you deposited. With $1,000 in margin and 10x leverage, a 5% price move produces $500 in PNL, which represents a 50% return or loss on the margin. The same 5% move on an unleveraged $1,000 position produces only $50.

What is a P&L statement in business?

A P&L statement shows whether a business made or lost money over a set period. Also called an income statement, it lists revenue at the top and works down through production costs, operating expenses, and tax obligations to arrive at net profit or net loss. It covers a defined accounting period (monthly, quarterly, or annually) and is not a real-time metric.

What is the difference between a P&L statement and a balance sheet?

A P&L statement covers performance across a period: it tracks what a business earned and spent and whether the result was a profit or a loss. A balance sheet captures position at a single moment: it lists what the business owns, what it owes, and the remaining equity on one specific date. Together they answer two different questions. The P&L asks "did the business make money this period?" The balance sheet asks "what does the business own and owe right now?"
