What is the difference between an RN salary with a BSN degree or an associate's degree?

This is totally dependent on where you are working. However, what I was told when I was in nursing school (and what I found to be true in the 4 years I've been a nurse) is that the pay for the same job is often the same whether you have BSN or just RN behind your name. The real difference comes in the types of jobs for which you can apply. You will find most nurse manager and administrative nursing jobs require at least a bachelor's degree. In both the hospital and in the clinic where I have worked, there was no difference in pay given to either the floor nurse or the charge nurse related to their degree.
