When navigating the world of financial markets, one of the most essential concepts traders and investors must grasp is unrealized profit and loss (P&L). Often referred to as "paper gains" or "paper losses," this metric reflects the current value of open positions—trades that have not yet been closed. While these profits or losses are not yet locked in, they play a critical role in assessing portfolio performance and making informed trading decisions.
Understanding unrealized P&L helps traders evaluate risk exposure, manage emotions around market fluctuations, and plan exit strategies effectively. Whether you're trading stocks, cryptocurrencies, or derivatives, this dynamic figure changes with every tick in price—offering real-time insight into potential outcomes.
What Is Unrealized Profit and Loss?
Unrealized P&L refers to the gains or losses on investments that are still held in a portfolio. Since the asset hasn’t been sold, the profit or loss remains theoretical—it exists only on paper.
This means:
- If the market value of your asset rises above your purchase price, you have an unrealized profit.
- If the market value falls below your entry point, you're sitting on an unrealized loss.
Only when you close the position does the unrealized P&L become realized—converted into actual gains or losses reflected in your account balance after accounting for fees and commissions.

Key Differences: Unrealized vs. Realized P&L
| Aspect | Unrealized P&L | Realized P&L |
|---|---|---|
| Status | Theoretical | Actual |
| Trigger | Based on current market prices | Occurs upon closing a position |
| Tax Implications | Generally not taxable | Often subject to capital gains tax |
| Account Impact | Affects equity but not cash balance | Directly impacts available funds |
While unrealized P&L gives a snapshot of performance, it doesn’t affect your usable capital until the trade is settled. This distinction is vital for managing liquidity and tax planning.
Practical Example: Calculating Unrealized P&L
Let’s say an investor buys 100 shares of a company at $50 per share**, investing a total of **$5,000.
Scenario 1: Market Price Increases
The stock climbs to $55.
- Unrealized Profit = (Current Price – Purchase Price) × Number of Shares
- = ($55 – $50) × 100 = $500
At this point, the investor sees a paper gain of $500. But unless they sell, this amount isn’t accessible as cash.
Scenario 2: Market Price Decreases
Now, suppose the stock drops to $45.
- Unrealized Loss = ($45 – $50) × 100 = –$500
The investor now has an unrealized loss of $500. Again, no money has changed hands—yet. If the price rebounds later, the loss could shrink or turn into a profit.
Once the position is sold, the outcome becomes final: either a realized profit or loss.
How Trading Platforms Display Unrealized P&L
Many brokerage platforms, including Interactive Brokers’ Trader Workstation (TWS), display unrealized P&L directly in the account dashboard. The calculation typically follows this formula:
Unrealized P&L = (Current Market Value – Average Entry Price) × Position Size
In TWS, users can view this data in both dollar value and percentage terms, helping them quickly assess performance across different assets. These figures update in real time as market prices fluctuate.
For active traders, monitoring unrealized P&L allows for:
- Timely risk assessment
- Stop-loss and take-profit adjustments
- Portfolio rebalancing
However, it's crucial to remember that these numbers are not guaranteed—they represent what would happen if positions were closed at current prices.
Why Unrealized P&L Matters for Traders
1. Risk Management
Tracking unrealized gains and losses helps identify overexposure to volatile assets. A large paper loss might signal the need to cut losses before further decline.
2. Emotional Discipline
Seeing big paper profits can tempt traders to hold too long, hoping for more gains. Conversely, deep paper losses may trigger panic selling. Recognizing that unrealized P&L is fluid encourages disciplined decision-making.
3. Performance Evaluation
While not final, unrealized P&L offers insight into the effectiveness of entry points and market timing. It complements realized results in building a complete picture of trading performance.

Common Misconceptions About Paper Gains and Losses
Some investors treat unrealized profits like guaranteed money—this can lead to poor financial choices. For example:
- Spending based on paper gains before selling
- Ignoring tax implications once gains are realized
- Overestimating portfolio health due to temporary market spikes
Remember: markets are unpredictable. A stock up 20% today could drop tomorrow. Only realized profits are truly yours.

Frequently Asked Questions (FAQ)
What happens to unrealized P&L if I don’t close my position?
Nothing changes unless the market moves. Your unrealized P&L will continue to fluctuate with price changes until you close the trade. No funds are added or deducted from your account until then.
Can unrealized losses become permanent?
Not technically—but if you eventually sell at a lower price than your purchase cost, the loss becomes realized. Holding indefinitely may allow recovery, but it also ties up capital and increases opportunity cost.
Does unrealized P&L affect my available margin?
Yes, especially in leveraged trading. Brokers use unrealized P&L to calculate your account equity, which affects margin requirements and may trigger margin calls if losses grow too large.
Is unrealized P&L taxable?
No. Tax authorities typically only recognize gains or losses when a position is closed—this is known as realized P&L. However, tax rules vary by jurisdiction, so consult a professional for personalized advice.
How often is unrealized P&L updated?
It updates continuously during market hours as prices change. Most platforms refresh this data in real time or near real time, giving traders instant feedback on their open positions.
Can I withdraw unrealized profits?
No. Only realized profits (cash in your account) can be withdrawn. Paper gains must first be locked in by closing the position and converting them into actual funds.

Final Thoughts
Unrealized profit and loss is more than just a number on a screen—it’s a powerful indicator of potential outcomes and risk exposure. By understanding how it works, traders can make smarter decisions, avoid emotional pitfalls, and maintain better control over their portfolios.
While it's tempting to celebrate paper gains or ignore small losses, disciplined traders know that only realized results count. Monitoring unrealized P&L should be part of a broader strategy that includes clear entry and exit plans, risk management rules, and realistic financial goals.
Whether you're using traditional brokerage platforms like TWS or modern digital exchanges, staying informed about your open positions ensures you’re always one step ahead in the fast-moving world of trading.
