US Fee Benchmarks for Interior Designers

Furnishings markup commonly runs 20–40% over net trade cost; design-only fees $6–12 per square foot, $12–20+ in luxury markets. These are planning benchmarks from published industry surveys — your market and positioning move them substantially.

The Rate Problem Is Usually a Pipeline Problem

Here is what the calculator cannot fix: a studio that only fields two inquiries a month has no leverage to quote properly. Fee resistance drops when affluent clients arrive already convinced — from your portfolio, your visibility in search and AI assistants, and the authority of your published work.

That is the business we are in. Nakada Design builds the marketing system — SEO, content, advertising and AI automation — that keeps qualified, high-budget inquiries arriving, so designers can price like specialists instead of competing like commodities.
