Web page design cost is the most frequently asked question in the web design world.
There isn't any formula for this question as some might expect but there are options to figure out how much will be the web page design cost.

It depends on a lot of factors:
- the number of pages
- the web design style
- content writing
- search engine optimization (SEO)
- used technologies (html5, jquery, flash, etc)
- the type of the site (is it a cms, blog, e-commerce related)

They all add up in time and the web page design cost depends mostly on the time the designer spends working.
The usual hourly for designers is around $10-20/hr. Always ask for the web page design cost before signing anything!
