I just saw that many in the community still have doubts about what PNL really is in finance. So here’s an explanation I hope will make things clear.

Basically, PNL stands for Profit and Loss, and it’s literally the thermometer of your trading. It shows you whether you made or lost money on a specific trade. Nothing more complicated than that.

The formula is very simple: Sale price minus purchase price, multiplied by the amount of asset you moved, and then subtract the commissions. That’s your PNL. If the number is positive, you made a profit. If it’s negative, well, you know.

Let me give you a real example that’s easier to understand. Let’s say you bought 0.1 BTC at $40,000, so you spent $4,000. Then you sold it at $42,000, receiving $4,200. The gross difference is $200, but after subtracting the exchange fee, you end up with something like $198 profit. That $198 is your positive PNL.

Now, there’s something important that not everyone understands: there is unrealized PNL, which is when you still have the position open and the price is changing every second. And then there’s realized PNL, which is when you’ve closed the trade and it’s a concrete number.

Things get a little more complicated when leverage and margin come into play. With leverage, your PNL can move much faster, both to gain and to lose. That’s why some people go crazy over it.

Think of it like this: if you bought a coffee for $50 and sold it an hour later for $70, your PNL is $20. Simple. If you sold it for $40, your PNL is -$10. The stock market works exactly the same, only the numbers are bigger and everything happens much faster. Sometimes we’re talking about thousands of dollars moving in minutes.

The key is that you understand that PNL is just the difference between what you paid and what you sold for. That’s all. When you master this concept, you start to see trading much more clearly. It’s one of those finance terms that seems complicated at first, but once you understand it, it’s the most obvious thing in the world.
