The interior design service fees are based on which pricing model?

• A. $30 per square foot with 10% coordination
• B. $40 per square foot with 5% coordination
• C. $25 per square foot with 15% coordination
• D. $50 per square foot with 12% coordination

Answer: (A)

Pricing interior design services commonly uses a base charge tied to the space plus a separate coordination fee. The base per-square-foot rate covers the design work for the area, while the coordination percentage accounts for the time spent managing meetings, consultants, vendors, approvals, and overall project logistics. This structure keeps the fee scalable with project size and ensures coordination efforts are explicitly included.

Choosing $30 per square foot with 10% coordination fits this model well. The base design fee scales with space, and the 10% coordination adds a manageable, proportional amount to cover project management tasks, making it a balanced and realistic combination often seen in practice. For example, a 2,000 square foot project would have a base of $60,000, plus a $6,000 coordination charge, totaling $66,000. The other options, while they might still compute to a total, show less typical pairing or less conventional percentages for the coordination component, so they’re not as strong an illustration of this standard pricing approach.
