How estimates the cost of the site project ?

[Tony Key]

For example, facebook or ebay ? What have an influence on the profit ?
For clarify, it is not about production but about the end project.
And thanks for the producing answer!

You need to break down all of the tasks that need to be done in order to complete the project. This would be a very long list for something like facebook or ebay. Then you need to estimate the duration required to complete each task. You need to know how much you would need to pay somebody an hour to do that task. So, let's say you need to create a new database and estimate that it will take 60 hours to create it. Your DBA costs $120/hour. So, that cost for that task is 60 * 120. Go down the list of each task and then add them all up.

You will also need to understand hardware costs. You may need to purchase servers or lease them.

Then there are marketing and ongoing operational costs, etc...etc...

Income minus costs equals profit (or lack there of). Keeping your costs lower increases you opportunity for profit. Look at each task and ask if there is a quicker or less costly way of doing it.
