I just realized that many new traders in futures trading often get confused about how to calculate leverage in futures. Today, I want to share some basic things I’ve learned from experience to avoid unnecessary account liquidation.

First is the matter of choosing the margin mode. This is very important. When you select Isolated Margin, the amount of margin you deposit (for example, $1,000 USD) will be the maximum you can lose. If the position gets liquidated, you only lose exactly that amount, and the rest of your account remains safe. But if you choose Cross Margin, your entire account balance will be used to maintain the position. When the price moves too strongly against you, you could lose everything. Therefore, my advice is to always choose Isolated first, and don’t rush into Cross until you truly understand the risks.

Now, onto a slightly more complex part—the way to calculate futures leverage. Leverage allows you to trade with a larger amount than your actual capital. For example, if you have $100 and use 5x leverage, you can open a position worth $500. Using 10x means $1,000. Sounds great, but this is a double-edged sword.

The most important thing I want you to understand is the relationship between leverage and the price drop that causes liquidation. This is the basic formula: the percentage of price decrease that leads to liquidation equals 100 divided by the leverage level. So with 5x, a 20% price drop will liquidate you. With 10x, only 10%. With 20x, just 5%. See, the higher the leverage, the easier it is to get liquidated. That’s why this way of calculating futures leverage is very important—it directly determines how much room you have to hold your position.

I also want to warn about very high leverage, like 30x, 40x or more. When you use such high leverage, the exchange will limit the actual amount used to maintain the position, possibly only half or two-thirds of it. The rest will be deducted from the insurance fund. As a result, you’re more prone to liquidation and have less chance to hold your position if the price bounces back.

In practice, when I trade, I usually use 5x to 10x leverage for swing trades. It gives me enough leverage for good profits but still leaves room for recovery. If you want to go above 20x, that should only be for super short scalp trades, and you must accept very high risk. I’ve never recommended using 100x unless you are a very experienced trader.

In summary, to avoid foolishly losing your account, remember: always choose Isolated Margin, understand how to calculate futures leverage before opening a position, use moderate leverage, and carefully calculate your liquidation point. If you’re a beginner, start with 5x, get used to it, then increase gradually. Don’t rush into high leverage because high profits also mean high risks. I’ve seen too many people lose everything because they recklessly used too high leverage.
