Calculation of Capital expenditure

Can anyone tell me what is the exact way to calculate the capital expenditure of a stock?
Like a formula or something.

I know this is a basic question and many of you will think that I must google the question. Actually, I looked up on Google as well as YouTube but didn’t get the clear answer. There is lot of information about the concept and it’s meaning. I understand the concept. But there are not any clear method of calculations that I came across. I just wish to calculate it for fundamental analysis of a stock.
Any reply would be immensely helpful.
