Okay, let’s tackle this. So Cynthia has 44 years of experience as an interior designer, which is extremely long-term. Her skills include concept design, rendering, space planning, and more. She’s based in West Palm Beach, Florida, which is a relatively affordable location. Interior designers with her level of experience typically charge higher rates, especially in high-demand areas. However, considering her location and the fact that she’s not a high-level designer (e.g., architect, designer at a large firm), I’ll estimate her rate to be on the lower side of the scale. Let’s check averages. Junior to mid-level interior designers in the US might average $50-$100 per hour. More experienced designers can charge $150-$250 per hour. Considering Cynthia’s long-term experience and skills, I’ll estimate her rate to be around $150 per hour.
