According to the Robert Half salary guide an employee with the CPA certification is paid, on average, 10% more than their non-CPA peers. This does not mean that everyone that gets their CPA automatically receives a 10% raise, but this is an average. There are many other factors involved such as geographic location, size of firm/company, responsibilities and duties, etc. Non salary benefits are also a big factor in this equation. Items such as vacation time, summer hours, medical coverage, and other non salary benefits can have a big influence on your overall compensation. The base salary of the position is only one piece of the compensation pie.
