I just had my first annual review for my first job (recent college grad). Review went very well. Met all my goals as well as exceeding a couple. Same goes for other expectations not directly related to my position.
I wasn't sure how to go about asking for a raise in general, and ended up asking about it at the very end of the meeting. At that point there is filled out paperwork of a raise ready for me. It caught me quite off guard as I thought we were going to start negotiating a bit. At this time I agreed to the raise.
Immediately after I regretted saying yes so quickly as I believe that I could've and should've gotten a higher amount. My question is what are best next steps? Do I just understand that I messed up during my first review process and take this as a learning experience? Do I bring it up to my manager in the near future and talk through it? I don't want to come off as being ungrateful for receiving a raise, but I also don't want to miss out on a year of higher pay because of a lapse that I had for a minute.
If I were to bring it up, I also don't know how much an appropriate amount would be to ask for. The only real reference I have been using as a guideline for averages in my position and region are Glassdoor.com. According to that I am paid ~10k less than the median salary for my area in my position. I don't know how much merit to give that, as I realize that the same position/title may not necessarily mean same responsibilities, skills, etc. at different companies. I also am only one year removed from college and understand that I may not receive the area median pay right away either.
