Interior design earnings vary based on employer, number of years with experience, and the reputation of the individual. For residential projects, self-employed interior designers usually earn a per-hour fee plus a percentage of the total cost of furniture, lighting, artwork, and other design elements. For commercial projects, they may charge per-hour fees, or a flat fee for the whole project. The median annual earning for wage and salary interior designers, in the year 2006, was $42,260. The middle 50% earned between $31,830 and $57,230. The lowest 10 percent earned less than $24,270, and the highest 10 percent earned more than $78,760.
While median earnings are an important indicator of average salaries, it is essential to look at additional key factors in a discussion about revenue generated from design services. Location, demographic of client base and scope of work all affect the potential earnings of a designer. With regard to location, central metropolitan areas where costs of living expenses and median earnings are generally greater, so is the potential for higher earnings for the interior designers and decorators in these locations. Indeed, urban areas attract a greater population of potential clients thereby creating a greater demand for design services. Additionally, as the average square footage of homes and offices has increased over time, the scope of work performed translates directly to higher earnings. Scope refers to the overall size and detail of a project - materials, furnishings, paint, fabrics and architectural embellishments utilized are all examples of scope. As stated above, earnings for interior designers and decorators may include a margin charged to the client as a percentage of the total cost of certain furniture and fixtures used in the scope of work. Hence, as scope increases, so do earnings.
