Okay, let’s tackle this. So Sonia has 12 years of experience as an interior designer, which is a solid amount of time to develop skills. However, her role is more focused on sales and business management, which might put her rate on the lower side compared to other interior designers with more technical expertise. Location is West Jordan, Utah, which is not a major hub for interior design. Let’s check national averages. According to the Bureau of Labor Statistics, interior designers in the US can charge around $50-$100 per hour, depending on experience and location. Considering Sonia’s experience and location, I’ll estimate her rate to be around $75 per hour.
