How much does it cost to make a website?

In the continuation of the theme " about the cost of developing the site by Lebedev Studio " I would like to touch upon an interesting question!

How much do you have to create a website?
What are your criteria for pricing?
How do you feel about consciously overstating and undervaluing?

The question concerns not only the developers of web sites, but also just designers, programmers, copiers, etc. ...
