I noticed that many people in the crypto markets ask what PNL really means. It's a term you see everywhere on trading platforms, so let's clarify it once and for all.

Basically, PNL is just profit and loss. Nothing complicated. It's the difference between the price at which you buy an asset and the price at which you sell it. If you buy BTC at $40,000 and sell it at $42,000, you make a profit. If you sell it at $38,000, it's a loss. There you go, that's your PNL.

But don't forget the commissions, they eat into your gains. So the formula is: PNL = (Sale Price – Purchase Price) × Quantity – Commissions. Let's take a concrete example: you buy 0.1 BTC for $40,000, spending $4,000. You sell it at $42,000, getting back $4,200. Paper profit is $200, but after the platform's commission, you're left with about $198 in profit.

What’s interesting with crypto PNL is that it constantly changes if your position is still open. This is called unrealized PNL — the profit or loss you haven't realized yet until you sell. Once you close your position, it's the realized PNL, which is concrete.

Another thing to understand is that PNL can be volatile. Prices move quickly in crypto, so your profit can turn into a loss in just a few minutes if you're not careful. That's why many traders constantly monitor their positions.

To give you a simple picture: imagine buying a coffee at $50 and selling it at $70 an hour later. You make a $20 profit. That's your positive PNL. If you had sold it at $40, you'd have a negative PNL of $10. In crypto, it's exactly the same, except the numbers are in dollars and it moves much faster.

So remember this: PNL = Sale Price – Purchase Price. If it's positive, you played it well. If it's negative, you'll learn for next time. And if you're using leverage or have a margin position, your PNL can be multiplied by 5, 10, or more. Double-edged sword, so handle with caution.
