Being able to pass a certification test(s) does not equal knowledge or proficiency. I hope you at least have an interest in computers and computer systems, specifically their maintenance and repair, because that is what these tests are designed to measure.
Anyway, the per test fee is posted at Prometric

The price of the training may include a test at the end but you will have to ask CBT Direct about that.
I have A+ & Network+ and they have not been much of a factor in my job search...however they do look nice hanging on the wall of my office.
