Okay, let’s calculate Mike’s rate. As an HR professional with an MBA and SPHR certification, he has a strong educational background. His skills in performance management, succession planning, and organizational development are in demand. Location is Greater Philadelphia, which is a mid-sized market. According to national averages, HR professionals with similar skills and experience can charge around $100–$150 per hour. Considering his education and certifications, I’ll estimate his rate to be around $125 per hour, slightly below the average. This is a reasonable estimate, taking into account the local market and his level of expertise.
