As the crypto market gears up for another major cycle, understanding key performance metrics becomes more important than ever. Among the most fundamental of these is PnL, or Profit and Loss. Whether you're a new trader or looking to refine your strategy, grasping PnL is essential for evaluating your trading success and managing risk effectively.
This guide breaks down what PnL means, the difference between realized and unrealized PnL, and provides clear formulas to calculate it yourself.
Understanding PnL in Trading
PnL, which stands for Profit and Loss, is a core metric used to measure the financial outcome of a trade or investment. It represents the difference between the entry price (the price at which you bought an asset) and the exit price (the price at which you sold or could sell it). By calculating PnL, traders can objectively assess the performance of their trades over a specific period, helping them identify what’s working and what isn’t in their strategy.
A positive PnL indicates a profit, while a negative PnL signals a loss. This simple yet powerful figure is the ultimate scorecard for any trading activity.
Realized vs. Unrealized PnL: What’s the Difference?
It’s critical to distinguish between the two main types of PnL, as they represent different stages of a trade and have distinct implications, especially for taxation.
Realized PnL
Realized PnL refers to the actual profit or loss that you have locked in by completing a trade. This occurs when you close a position—selling a cryptocurrency you bought or buying back an asset you sold short. This profit or loss is "real" because the trade is finished, and the gains or losses are settled. Only realized profits are typically subject to capital gains tax.
Unrealized PnL
Unrealized PnL, also known as "paper" profit or loss, reflects the current value of your open positions. It shows what your profit or loss would be if you were to close the position at the current market price. This number fluctuates with the market until you actually close the position and realize the gain or loss.
How to Calculate PnL in Crypto Trading
Calculating your PnL is straightforward once you have the necessary data: the entry price, exit price, and the size of your position. The formulas differ slightly for long and short trades.
Calculating PnL for a Long Trade
When you open a long position, you are buying an asset with the expectation that its price will rise. The formula to calculate your PnL is:
PnL = Number of Units × (Exit Price - Entry Price)
Example: You buy 0.5 Bitcoin at an entry price of $40,000. You later sell it when the price reaches $45,000.PnL = 0.5 × ($45,000 - $40,000) = 0.5 × $5,000 = $2,500 Profit
Calculating PnL for a Short Trade
When you open a short position, you are selling an asset you borrowed, expecting to buy it back at a lower price. The formula is:
PnL = Number of Units × (Entry Price - Exit Price)
Example: You short-sell 1 Ethereum at an entry price of $3,000. You later buy it back to close the position at $2,500.PnL = 1 × ($3,000 - $2,500) = 1 × $500 = $500 Profit
Understanding PnL Percentage and Ratio
While the raw PnL figure tells you the monetary value of your gain or loss, the PnL Percentage and PnL Ratio provide deeper insight into the efficiency and effectiveness of your trade relative to your initial investment.
PnL Percentage
The PnL Percentage shows the return on your initial investment as a percentage. It helps you compare the performance of trades of different sizes.
PnL Percentage = [(Exit Value / Entry Value) - 1] × 100%
Example: You invest $1,000 to buy a crypto asset. Later, you sell that asset for $1,200.PnL Percentage = [($1,200 / $1,000) - 1] × 100% = (1.2 - 1) × 100% = 20% Profit
PnL Ratio
The PnL Ratio (or Profit/Loss Ratio) is a risk-management metric that compares the average profit from your winning trades to the average loss from your losing trades. A ratio greater than 1 means your average profit is larger than your average loss, which is generally positive.
PnL Ratio = Total Profit from Winning Trades / Total Loss from Losing Trades

The Importance of Tracking PnL
Consistently monitoring your PnL is not just about knowing if you made money. It serves several critical functions for any serious trader:
- Performance Evaluation: It provides a clear, quantitative measure of your trading strategy's success.
- Risk Management: By understanding your losses, you can adjust position sizes and set stop-loss orders to protect your capital.
- Tax Reporting: Realized PnL is essential for accurately reporting capital gains and losses to tax authorities.
- Strategy Refinement: Analyzing which trades were profitable helps you refine your entry and exit strategies over time.
Frequently Asked Questions
What is the difference between PnL and ROI?
PnL is the absolute monetary value of your profit or loss in a trade (e.g., +$500). ROI (Return on Investment) is a percentage that measures the efficiency of that investment relative to its cost (e.g., a 20% return). PnL gives you the cash value, while ROI allows for easy comparison between different investments.
How do fees and funding costs impact PnL?
Transaction fees (taker/maker fees), withdrawal fees, and, for leveraged positions, funding costs, all reduce your final PnL. For an accurate calculation, you must subtract all associated costs from your gross profit or add them to your gross loss. The formulas above calculate gross PnL; net PnL accounts for these costs.
Is unrealized PnL taxed?
In most jurisdictions, unrealized PnL is not taxed. You are only taxed on realized gains when you officially close a position and settle the trade. It is crucial to understand the specific tax laws in your country regarding cryptocurrency transactions.
How can I track my PnL automatically?
Most modern cryptocurrency exchanges and dedicated portfolio tracking apps provide built-in tools that calculate your realized and unrealized PnL automatically. These platforms connect to your exchange accounts via API and update your P&L in real-time, saving you from manual calculations. You can also 👉 explore more strategies for managing your portfolio.
What is a good PnL ratio?
A PnL ratio above 1.0 is generally considered good, as it indicates that your average winning trade is larger than your average losing trade. However, this ratio should be considered alongside other metrics like win rate. A high ratio with a low win rate can still be profitable, and vice versa.
Why is my unrealized PnL constantly changing?
Your unrealized PnL is based on the current market price of your open positions. Since cryptocurrency prices are highly volatile and change by the second, your unrealized P&L will also fluctuate constantly until you close the position and realize the gain or loss.
