You say your rate on a discovery call, and the client pauses just long enough for your stomach to drop. Then comes the line: “I’m interviewing someone who charges way less.”
It is one of the most familiar moments in a design business, and it lands hard because most designers have never done the math needed to answer it calmly. They quoted a number that felt defensible in the moment, but they cannot explain where it came from.
That is the real issue the Interior Design Community question of the day put on the table: what should the minimum hourly rate for interior designers actually be? Not because there is one universal number, but because too many designers are running on a rate they inherited, guessed at, or never revisited.
A minimum hourly rate is not a market benchmark. It is the lowest number that still covers your overhead, pays you fairly for your expertise, and protects the project from scope creep. Here is a practical way to find yours, and to explain it without getting defensive.
What Your Hourly Rate Is Actually Carrying
Before you set a number, get clear on what that number is meant to support.
An hourly design rate is not just labor. It covers design thinking, planning, and documentation. It covers client communication, decision support, vendor coordination, and trade relationships. It covers site visits, install oversight, and punch work. If you are doing full-service work, your rate is supporting a level of project leadership that a quick paint consultation does not require.
If you offer both types of services, consider whether a single rate makes sense for both scopes. Many designers find that differentiating their rates, or separating services into distinct pricing models, makes billing cleaner and conversations shorter.
This is worth clarifying before you run any numbers. The math only works if you know what the rate is doing.
The Pricing Floor Formula You Cannot Skip
The simplest way to find your minimum hourly rate is to build it from the ground up.
Start with your annual business overhead: software, insurance, rent if applicable, marketing, accounting, any support staff or contractors, and continuing education. Add your desired salary, meaning what you actually need to pay yourself to live, save, and plan for retirement. Then add profit as a planned line item, not a bonus you hope will appear. Divide that total by your realistic billable hours for the year.
That last number is where most designers miscalculate. If you are solo and doing full service, 1,000 billable hours per year is often a more honest estimate than 1,600. Vendor follow-up, business development, admin, and client communication all consume time you cannot bill. If you have never tracked your hours, do it for two weeks. Categorize every activity as billable, non-billable, admin, or marketing, then extrapolate.
The formula is not complicated. What is complicated is being honest about the inputs. If your overhead is higher than you expected and your billable hours are lower, the resulting number may surprise you.
That is the point. The surprise means you were likely underpriced.
Tiered Rates and Role Clarity
Many studios bill at multiple rates based on role, and it is one of the cleaner ways to stay profitable across different project phases.
A common structure: principal rate for vision, decision-making, and high-stakes client meetings; senior designer rate for independent documentation and project management; junior designer rate for sourcing, drafting, and sample coordination; and a separate lower rate for procurement admin if it is billed at all.
If you are a solo designer handling all those roles yourself, you can still tier. Some designers bill “design strategy” at one rate and “procurement coordination” at another. Others fold those distinctions into a flat fee rather than itemizing them hourly. Either way, identifying the tiers internally helps you understand what your blended rate must cover.
The community conversation surfaced some real numbers worth absorbing.
@waldron_designs shared: “We currently bill at $245 and have not had any pushback for quite a while, so I’m thinking we’re under-billing, but the rate makes my partner squirm, so we keep it for a bit longer.” That hesitation is understandable. It is also a signal. When the market stops pushing back, the rate may have room to move.
@bpcarchitecture offered a frame that resets the whole conversation: “I charge north of $300/hr….that’s less than 10 dollars an hour for every year since college graduation 🙂 …and fees still end up being less than what it costs to pay the interior painting contractor.”
That math is worth sitting with.
When Hourly Is the Wrong Tool
Hourly billing works well for consultations, small scopes with clear deliverables, and additional services added after the original agreement. It starts working against you on full-service furnishing and renovation projects with shifting timelines, multiple decision-makers, or high client involvement.
The clients who most need you to track every hour are often the ones who will resent seeing it on an invoice. For those projects, a flat fee or phased flat fee tends to protect your margin while creating a smoother client experience.
@sonia_sacd described her approach: “We don’t charge hourly. We propose a lump sum fee depending on size and scope of project. The hourly rate is only there for additional in-house support hours for coordinating with third parties, supervision or site inspection.”
That structure works because the client gets a clear investment number and the designer gets protection from scope creep, without having to justify every billable increment.
If you are working through when to use hourly versus flat fee for different project types, the To-The-Trade episode Pricing Strategies for Designers with Sarah Brohm covers how she structures a flat fee model built on hours multiplied by rate, which captures the discipline of hourly without the friction.
When a Client Mentions a Cheaper Designer
This is the moment most designers dread. It is also the moment where a well-built rate earns its keep.
@serenityhomestyling shared exactly this scenario: “I had a potential client reach out last week and when I told them my hourly rate, he said well I’ve got another designer I’m interviewing who charges $100. I wasn’t exactly sure how to respond. We live in the New York State area and I thought that was extremely low.”
The instinct is to defend the number or get drawn into a comparison. A calmer approach: let them compare, but give them the right tools to do it.
Try this: “Totally fair to compare options. Before you decide, ask what deliverables are included, how they handle revisions, whether they provide procurement, and how they manage the project timeline. If you’d like, I can send a one-page scope outline so you can compare.”
Then stop talking. Let them decide.
If you want to add one more layer: “I focus on thorough documentation, proactive project management, and a smooth installation. That is what my clients are paying for.”
The goal is not to win an argument. The goal is to make the comparison real so the client can see what they are actually choosing between.
@top_rail_interiors put the underlying logic plainly: “Look at what the electricians are getting then add a bit.” The point is not to copy a contractor’s pricing model. It is that skilled professionals across every trade charge professional rates without extensive justification, and designers can do the same.

Owning the Number You Set
Pricing confidence is often a clarity problem, not a courage problem. When designers know exactly how their rate was calculated and what it is designed to protect, the conversation changes.
@laurabrown.design shared an observation from a home show in Savannah: “The general public has absolutely NO idea what our value is or how we charge. It’s our responsibility to educate and be confident and consistent. High tides raise all ships!”
That framing matters. A clear minimum rate is not just a personal business decision. It is part of how the industry holds its value over time.

One Move to Make This Week
You do not have to overhaul your pricing structure today.
Pick one concrete action: raise your consultation rate, add an “additional services” hourly clause to your agreement, build a flat-fee template based on scope and estimated hours, or put together a one-page “how to compare proposals” document for prospects.
The floor you set is not permanent. It is a starting point you revisit as your overhead changes, your experience deepens, and your market responds. What matters most is that the number comes from real math, not from what you think you can get away with charging.
