Recently, someone asked me what PNL means in trading, and I realized that many beginners still don’t have a clear understanding of this concept. So here’s an explanation I hope will be helpful.

PNL is the abbreviation for Profit and Loss, or gains and losses in Spanish. Basically, it’s what you define when you close a trade: how much money you earned or lost. Plain and simple.

If I think about it from the most basic level: you bought something at a certain price, sold it at another price. The difference between those two prices is your PNL. If the number is positive, you gained. If it’s negative, you lost. That’s all you need to know at the beginning.

The actual formula is quite straightforward: PNL = (Sale Price - Purchase Price) × Quantity of asset - Commissions. Commissions are important because they take a piece of your profit. It’s not much, but it adds up.

Here’s an example that everyone understands: let’s say you bought 0.1 BTC at $40,000. You spent $4,000. Later, you sold it at $42,000 and received $4,200. Your gross profit was $200, but after subtracting the exchange fee, your PNL ended up at approximately $198.

Now, here’s where it gets interesting. There are two types of PNL you need to know. There’s unrealized PNL, which is the gains or losses you have on a position that’s still open. That can change every second because the price moves. And there’s realized PNL, which is the gains or losses you’ve already closed, when you sold and the trade ended.

Many new traders get confused because they see their unrealized PNL in green (profit) and think they’ve already made money. But no, that’s only on paper. Only when you close the position and turn that unrealized into realized, then it’s truly yours.

There’s a related concept called ROI, which is the return on investment in percentage. It’s useful for comparing trades of different sizes. There’s also margin, which is the collateral you put up to open leveraged positions. And speaking of leverage, that’s a multiplier that directly affects the size of your PNL, both for better and for worse.

A simple way to think about it: imagine you bought a coffee for $50 and sold it an hour later for $70. Your PNL is +$20. If you sold it for $40, your PNL would be -$10. In trading, it’s exactly the same, only the numbers are bigger and everything happens much faster.

The important thing is to understand that PNL is your financial thermometer. It tells you if you’re doing things right or if you need to adjust your strategy. And remember: there’s always volatility involved. The price goes up and down, and that affects your PNL while the position is open.

Anyway, that’s what PNL means in trading. It’s the final result of your trades. Keep it simple, learn to calculate it, and use that information to improve.
