How Much does it Cost to Hire an Interior Designer?

If you’ve ever started planning a remodel or felt stuck trying to make your home feel cohesive, you’ve probably wondered: how much does it cost to hire an interior designer? The answer can feel confusing—because the truth is, it depends.

Pricing varies based on things like the designer’s experience, certifications, location, and the scope of your project. And if you’ve never worked with a designer before, it’s easy to feel blindsided by costs you didn’t expect or plan for.

In this post, I want to give you a clear, no-fluff explanation of what goes into interior design pricing—especially here in the Dallas, TX area. We’ll walk through common fee structures, what designers actually do behind the scenes, and how things like product sourcing and project management impact the bottom line.

Whether you’re thinking about hiring a designer for the first time or just want to better understand how it all works, this guide will help you approach your next project with confidence (and a realistic budget).

When you’re looking to hire an interior designer, it’s important to understand how designers charge for their work—before you start the process. Not every designer bills the same way, and knowing what to expect can help you choose someone whose pricing model aligns with your project and budget.

Here are the five most common interior design fee structures you’ll come across when interviewing designers:

1. Hourly Rate

2. Flat Fee

3. Square Footage Rate

4. Percentage of Project

5. Hybrid Fee Structure

Each of these has pros and cons depending on the size and complexity of your project. In the next section, I’ll break down what each one means and when it’s typically used.

Interior Design Fee Structure #1 - Hourly Rate

Charging by the hour is one of the most common and straightforward ways interior designers bill for their time. With this structure, you’re billed for the actual hours spent working on your project—from sourcing materials to drawing floor plans to managing installations.

Pros of Hourly Billing

• Transparency: You’ll see exactly how much time is being spent and where it’s going. A good designer will keep you updated throughout the process so there are no surprises.

• Flexibility: This structure allows for changes along the way without having to renegotiate a full contract. It’s ideal for evolving or undefined scopes of work.

• Customization: You can focus the designer’s time (and your budget) on the areas that matter most to you—whether that’s space planning, finish selection, or furnishings.

Cons of Hourly Billing:

• Unpredictability: If you’re someone who needs a firm number up front, this model might feel a little too open-ended. It’s harder to know the total cost until the project is finished.

• Potential Overages: Large-scale projects can get expensive quickly if the scope shifts or unexpected challenges pop up. It’s important to get a clear estimate of the minimum hours required before starting.

• Efficiency Varies: The total cost will depend on how quickly your designer works. Many newer designers start with hourly billing because they’re still figuring out how long things take.

Hourly rates for interior designers can range widely depending on experience, location, and the complexity of the work. In the Dallas area, expect to see rates between $125 and $300+ per hour.

Most designers who charge hourly will also require an upfront deposit, which covers a set number of hours and reserves time on their calendar.

If you’re considering hiring an interior designer with an hourly rate, make sure to ask for an estimate and a clear scope of work up front to avoid budget surprises later on.

Interior Design Fee Structure #2 - Flat Fee

Flat fees are another common pricing structure—and one you’re likely to see when working with more experienced interior designers. Quoting a flat fee upfront requires a solid understanding of the project scope and how much time, planning, and management it will take to get you from start to finish.

With this structure, you’re given one set price for the entire project, based on a clearly defined scope of work. This fee covers the design services needed to achieve the vision you’re after—no surprises, no tracking hours.

Pros of Flat Fee Billing:

• Predictability: You’ll know the full cost of your interior designer’s services upfront, which gives you peace of mind throughout the process.

• Simplicity: There’s no need to track hours or monitor how much time is being spent. You can focus on the design, not the clock.

• Better Budget Control: Since the fee is fixed, it’s easier to plan and allocate your total project budget—leaving you room to prioritize upgraded materials or finishes.

Cons of Flat Fee Billing

• Less Flexibility: If the scope of work changes mid-project, your designer may need to issue a change order or adjust the fee.

• Sticker Shock: Seeing the full design fee all at once can feel like a lot—even if it ends up costing the same as hourly billing in the long run.

• Scope Clarity is Crucial: Misunderstandings about what’s included in the flat fee can cause frustration. This is why an initial consultation is so important—to clearly define expectations on both sides.

Flat fees vary widely depending on the size and complexity of the project. You might invest $4,000–$10,000 to furnish a single room or $25,000–$100,000+ for full home design with project management

A general rule of thumb? Interior design fees typically fall between 10–30% of the total project budget, depending on the designer’s experience and the level of involvement required.

Interior Design Fee Structure #3 - Square Footage Rate

Some interior designers charge a set fee per square foot of the project area. While not as common as hourly or flat-fee models, this structure is typically used for larger projects—like full-home renovations, new construction, or commercial spaces—where the overall square footage helps determine the complexity and scale of the work.

Pros of Square Footage Pricing:

• Simplicity: It’s easy to calculate the estimated design fee based on the size of your space—no formulas or hourly tracking needed.

• Transparency: Because the rate is tied directly to square footage, you’ll know upfront how additional rooms or increased scope could affect cost.

• Consistency: This structure can make it easier to compare pricing across designers or past projects, especially for larger renovations or full builds.

Cons of Square Footage Pricing:

• Less Value for Smaller Spaces: For smaller projects, this model may feel less cost-effective. There’s typically an economy of scale with larger homes, so the rate per square foot may be higher to cover a designer’s baseline costs.

• Doesn’t Account for Project Complexity: Not all square footage is created equal. A home with intricate architecture or lots of custom details may require far more design time than the price per square foot reflects.

• Location-Driven Pricing: Rates vary widely by market. In higher-cost areas like Dallas, I’ve seen rates exceed $30 per square foot, especially for high-touch, full-service design.

Interior design fees based on square footage typically range from $8–$30+ per square foot, depending on the type of project and designer’s experience.

While Paige Studio doesn’t typically use this structure, I’ve found that our design fees for large-scale renovations or new builds often fall in the $15-$21 per square foot range once everything is said and done.

Interior Design Fee Structure #4 - Percentage of Project Fees

Percentage of project fees involve charging a percentage of the total project cost. While less common than other fee structures, some designers may use this approach.

Advantages:

1. Financial Predictability: Clients may appreciate the financial predictability offered by percentage-based fees. With this structure, clients can anticipate the designer's fee as a proportion of the overall project cost, providing clarity on budget allocation from the outset.

2. Budget Flexibility: Clients with flexible budgets may appreciate the percentage-based fee structure, as it allows them to scale the scope of the project without renegotiating fees. This flexibility can accommodate changes or additions to the project as it progresses.

3. Risk Sharing: By basing fees on the project's total cost, clients may feel they're sharing the risks associated with the project with the designer. This can provide clients with a sense of security knowing that the designer is invested in the project's success.

Disadvantages:

1. Lack of Transparency: Percentage-based fees may lack transparency, as clients may be uncertain about how the fee is calculated or what services are included. This opacity can lead to misunderstandings or disagreements about the final cost of the project.

2. Potential for Conflicts of Interest: Clients may worry about potential conflicts of interest if the designer's fee is tied to the project's total cost. There may be concerns that designers could prioritize higher-cost options to increase their fee rather than focusing on the client's best interests.

3. Limited Budget Control: Clients with strict budgets may find percentage-based fees challenging to manage, as the final cost of the project is directly tied to its total cost. This lack of control over fees may cause anxiety or uncertainty about staying within budget constraints.

Percentage of project fees for interior design projects typically range from 10% to 30% of the total project cost, depending on factors such as project complexity, size, and the designer's expertise.

Interior Design Fee Structure #5 - Hybrid Fee Structure

A hybrid fee structure combines elements of both flat fee and hourly rate models, offering a tailored approach to meet the needs of clients throughout the design and implementation phases. This structure typically involves a flat fee for the design phase and hourly billing for project management during implementation and is the structure we use here at Paige Studio.

Advantages:

1. Cost Control: Clients benefit from cost control during the design phase with a predetermined flat fee. This provides clarity on the investment required for the initial design work, helping clients budget effectively without the risk of unexpected charges.

2. Flexibility: The hybrid structure offers flexibility by transitioning to hourly billing for project management during implementation. This allows clients to pay for services as needed, particularly during the active construction or installation phase, without committing to a fixed fee for ongoing project management that may or may not be needed.

3. Tailored Services: Clients receive tailored services to suit their project needs at different stages of the design and implementation process. The flat fee for design ensures comprehensive planning and conceptualization, while hourly project management allows for hands-on oversight and coordination as needed during execution.

Disadvantages:

1. Potential for Cost Overruns: Hourly billing for project management during implementation may lead to cost overruns if unforeseen complications arise or if the project takes longer than anticipated. Clients may worry about exceeding their budget if hourly rates accumulate beyond initial projections. To mitigate this, a comprehensive plan before demolition begins is essential. At Paige Studio ensure every detail is planned and documented in the design phase which allows the implementation phase of our projects to be relatively smooth.

2. Complex Fee Structure: The hybrid fee structure can be more complex to understand compared to straightforward flat fees or hourly rates.

3. Dependency on Communication: Effective communication between the client and designer is essential to ensure the success of the hybrid fee structure. Clients must actively engage with the designer during the implementation phase to maximize the value of hourly project management services, which may require additional time and effort on their part. When working with Paige Studio, we send weekly updates at all phases of the project - so you understand exactly what is going on from concept to completion.

At Paige Studio, we employ a hybrid fee structure because we believe it offers the best of both worlds for our clients. By combining the predictability of flat fees with the flexibility of hourly billing, we can provide tailored services that meet the unique needs of each project stage. This approach ensures cost-effective solutions while maintaining the highest standards of design excellence so you end up with a home you love.
