As I know, the PCB manufacturing costs depend on several factors in design. If you are a newbie in the PCB field, maybe your design is not optimized from a cost standpoint. The majority of beginners may forget the basic width, spacing and other rules that have a big impact not only in the tooling costs but also in the unit prices. I know that price is approximately proportional to the board’s area. To keep the total costs to a minimum, are there any more recommendations to follow?
