Binance Isolated Margin PnL calculation

Hello everyone I'm new here! :)I'm having trouble trying to calculate my profit or loss when i'm on isolated margin.

I tried to figured out with maths but i'm not quite good with them ????????

I came out with this calculation:

​

• Total Balance in my isolated margin wallet (x3 or x5 or x10) = margin level
• Balance that I'm going to use in the trade (x2 or x4 or x9) = the borrow (in USD /in Crypto at that time)

So:

USD borrow - (borrow in crypto x actual or target price of the crypto) = Profit n' Loss

​

Is this the right and more simple way to calculate my probable profit or loss?

Again me and maths have a bad relationship so excuse me if I wrote the calculation badly ????

Thanks:)
