Introduction
In the world of trading and investing, understanding your profit and loss (PnL) is fundamental. It’s the clearest indicator of your performance. PnL is broadly categorized into two types: realized and unrealized. While they might seem similar at first glance, they represent very different stages of a trade’s lifecycle and have distinct implications for your portfolio and tax obligations.
Grasping this difference is crucial for making informed decisions, from when to exit a position to how you report your earnings. This guide will break down these concepts in simple terms, explaining what they are, how they are calculated, and why they matter to every investor.
What is Unrealized PnL?
Unrealized PnL, also known as "paper profit" or "paper loss," refers to the theoretical gain or loss on an open position. It represents the change in the value of your holdings based on current market prices versus your entry price. This figure is "unrealized" because you have not yet closed the position; the profit or loss exists only on paper or your trading screen until you decide to sell.
- In Stocks: It's the difference between the current market price of a stock and the price you paid for it, multiplied by the number of shares you hold.
- In Futures/Crypto: It reflects the change in the mark price of a contract since you opened your position.
Your unrealized PnL fluctuates constantly with every tick of the market price. It provides a real-time snapshot of how your open trades are performing at any given moment. If the market moves in your favor, you see an unrealized gain; if it moves against you, you see an unrealized loss.
What is Realized PnL?
Realized PnL is the actual profit or loss you have made from a trade that has been completed, or closed. It becomes "realized" the moment you sell a security or settle a contract. This is the tangible gain or loss that is locked in and added to or subtracted from your account balance.
The calculation is straightforward: it is the difference between your exit price and your entry price, adjusted for any trading commissions, fees, or financing costs. Unlike unrealized PnL, this number is fixed once the trade is closed and will not change with subsequent market movements. Realized PnL is what ultimately affects your net cash position and is used for calculating tax liabilities.
Key Differences Between Realized and Unrealized PnL
While both metrics track performance, they serve different purposes and are used in different contexts. The table below summarizes the core distinctions.
| Feature | Unrealized PnL | Realized PnL |
|---|---|---|
| Status | Applies to open, active positions. | Applies to closed, completed trades. |
| Value | Fluctuates continuously with the market price. | Fixed and final once the position is closed. |
| Impact | Shows potential profit/loss; does not change cash balance. | Shows actual profit/loss; directly changes cash balance. |
| Taxation | Not taxable until the position is closed and profit is realized. | Taxable event in most jurisdictions. |
Understanding these differences is key to effective portfolio management. Unrealized PnL helps you make decisions about open trades, while realized PnL tells you the definitive outcome of your past decisions.
Why Understanding PnL is Crucial for Traders
Monitoring both types of PnL is not just an accounting exercise; it’s a critical component of a successful trading strategy.
For Strategic Decision-Making: Your unrealized PnL helps you decide whether to hold a position for further potential gains or cut a loss short. It informs your risk management, helping you determine when to move stop-loss orders or take profits.
For Risk Management: By tracking unrealized losses, you can assess your exposure and ensure that a single trade doesn’t jeopardize your entire portfolio. It allows you to manage drawdowns effectively.
For Performance Analysis: Realized PnL is the true measure of your trading performance over time. Analyzing your history of realized gains and losses helps you refine your strategy, identify what works, and eliminate what doesn’t.
For Tax Planning: Knowing the difference helps you plan for tax season. You can make strategic decisions about which positions to close before the year-end to manage your capital gains tax liability.

Frequently Asked Questions
Q: Does unrealized PnL affect my account balance?
A: No, it does not. Unrealized PnL is a theoretical value that shows the potential profit or loss of your open positions. It does not change the actual cash balance in your account until the position is closed and the PnL becomes realized.
Q: When does unrealized PnL become realized?
A: Unrealized PnL becomes realized the moment you close all or part of a position. Selling a stock, exiting a futures contract, or settling a trade will convert the paper gain or loss into a real one, which is then reflected in your available cash.
Q: Are realized profits taxable immediately?
A: In most countries, yes. Realized profits are typically considered a taxable event in the year that the trade is closed. The specific tax treatment (e.g., capital gains tax) depends on your country's laws, the type of asset, and how long you held it. Unrealized gains are not taxed.
Q: Can unrealized losses be used for tax purposes?
A: Generally, not until they are realized. You cannot claim a capital loss on your taxes for a position that is still open and showing an unrealized loss. You must close the position to realize the loss and use it to offset realized gains for tax purposes.
Q: Which is more important to watch?
A: Both are important but for different reasons. Active traders must watch unrealized PnL to manage open risk. For overall financial health and performance review, realized PnL is the definitive metric, as it represents the money you have actually made or lost.
Q: Do dividends affect realized or unrealized PnL?
A: Dividends are a form of realized profit. When a company pays a dividend to you as a shareholder, it is a tangible cash inflow that is immediately realized and added to your account balance. It is separate from the change in the stock's market price.
