Hehe, your question is flawed. But I think I know what you mean. For example.

If the futures price of soybean meal in a month is 4000 yuan, and the primary contract value is 4000 * 10 = 40000 yuan.

If the contract margin this month is 5%, that is, you only need 40,000 * 5% = 2,000 yuan to buy a futures contract with a quantity of 10 ton and a value of 40,000 yuan.

If I guess correctly, what you want to know is 40000/2000=20 times. In other words, the actual contract value (40000) you actually control is 20 times that of the investment (2000).

I hope I can help you.
