It depends on the issue. $400 is a starting point. Some polygraph examiners will charge as much as $1500 for a polygraph test.

The instrument is a different story. They're now using computerized polygraphs. The software program and equipment will run around $6K. A used analog instrument will run around $1,200

i think about $400.00
