If you work in an exempt industry, I would expect 0%. Actually, for the most part, this is true of any self improvement you do while employed. It's the same thing if you were to go back to school and get a degree. At my last job I worked with a guy who was a test technician and he was going to night school to get his EE degree. When he graduated he was told that unfortunately the company did not currently have any openings for Electrical Engineers, but when something opened up he would get first consideration. Within a year he was working for another company. As John indicated, your PE (or degree or whatever) MAY help your career with your current employer some time down the road, but if you are looking for payback now, your only real option is to polish up your resume and start looking, preferably for a position where a PE is desired.
