I noticed that many people jump into crypto trading without really knowing how to calculate their actual gains. It’s a shame, because it’s simpler than you think, but you have to understand the basics.

As I often explain, crypto profit is really just this: what you sell for minus what you bought for, minus all the fees. Period. But that’s where it gets interesting, because fees are often what people forget.

Let’s take a concrete example. You buy 1 BTC at 20,000 dollars. You sell it at 25,000 dollars. On paper, you have 5,000 dollars in gains. But wait—the exchange charges you 0.2% in fees on the sale, so 50 dollars. Your real profit is therefore only 4,950 dollars, which is about a 24.75% return on your initial investment. That’s already pretty good, but it’s less than what you thought at first.

With USDT pairs, it’s even simpler. You buy ETH for 1,500 USDT and you sell it for 1,800 USDT. Without fees, that’s a 20% gain. Easy.

But here’s the catch: when you trade regularly, things become more complex. Maker and taker fees add up. There’s also slippage—that difference in price between the moment you place your order and when it gets executed. Then there are withdrawal fees if you take your funds out. And in many countries, crypto gains are taxable, so you really need to keep track of everything.

That’s why I always recommend keeping a clean record. A simple Excel or Google Sheets spreadsheet is enough. Log every transaction—the entry price, the exit price, the quantity, the fees. Do it regularly, not once a year. Always use the same currency for your records, like USDT or USD, to stay consistent.

An important thing to understand: there’s a difference between unrealized profit and realized profit. Unrealized profit is simply the current value of your positions that you haven’t sold yet. That can change every day. Realized profit is the money you’ve actually made when you sold. That’s the one that matters for your taxes and your real gains.

Honestly, once you’ve mastered these concepts, calculating your crypto profit becomes routine. The key is never to forget the fees, to track your transactions properly, and to distinguish what you truly gained from what you think you gained on paper. Serious traders use automated tools for this, but even a good old spreadsheet works if you’re disciplined.
