I got a salary bump effective the date I received my passing results (5/25/15). 5% increase, which is a little over $4,000/yr. You can do the math.
May I ask how old you are?
This is where I think it becomes advantageous to get the PE a bit later on in ones career when it actually means something. I took a new job last year with a large firm and negotiated a very competitive salary. I am hoping i passed this exam, and if I do, there is an understanding that I will be receiving at min a 10% bump. Had I already had the PE when i took the job last year, I doubt i would have gotten them to come up that 10% from the offer i got.
When you get it as a younger engineer and you arent utilizing the stamp, your employer isnt really going to pay you accordingly because at that point in your career you arent offering any additional value to the firm. You are still a jr engineer, not leading projects, not at the top of the org chart, and not signing/sealing drawings.
When you get a bit more senior and ARE getting more responsibilities and are THE MAN, then they're going to pay you for it. My firm has a ton of PE's, but none currently in my business group. When (If?) i get it, I will be THE MAN. And will be paid accordingly.
I get that its nice to pass the exam, and get it out of the way early, i just think that a lot of folks short change themselves that way. Just my 2 cents.
