Okay, let’s calculate Barry’s rate. He has a strong background in automotive electronics and engineering management, which are in demand. His certification as an iNarte EMC Senior Engineer adds credibility. Location is the Detroit Metropolitan Area, which is a hub for automotive industry. According to national averages, senior EMC engineers with similar experience and certification can charge around $100–$200 per hour. Considering Barry’s expertise and certification, I estimate his rate to be around $125 per hour, which is slightly below the average but still reflects his value.
