Freelance interior designers in the US and EU bill $50–$150/hour, usually wrapped in flat fees per room or per project — with a second income stream the hourly number hides: procurement. Trade discounts and sourcing markups on furniture and finishes can rival the design fee itself on full-service projects.
Design time is only half the job; the rest is site visits, contractor coordination, and the email marathon of samples and approvals. Designers who quote a flat fee from the floor plan alone — before scoping revision rounds and sourcing hours — discover the difference between a design fee and a design donation.

Pricing tips for freelance interior designers
- Quote per room or per project with revision rounds capped in writing; concept-to-approval is where hours vanish.
- Decide your procurement model deliberately — cost-plus markup or flat sourcing fee — and disclose it; opacity kills referrals.
- Charge for site visits and contractor coordination as their own line; 'quick site check' is a four-hour round trip.
