Markup percentage in interior design typically ranges from 20% to 40% on products, with 35% being the industry average.
The exact markup varies based on product category, market positioning, regional factors, and the designer's business model and reputation.
| Aspect | Details | Typical Ranges |
|---|---|---|
| Product Markup | Additional percentage added to wholesale cost of furniture, lighting, and accessories | 20% to 40%, with 35% average; luxury items can reach 50-60% |
| Service Fees | Compensation for design work, consultations, and project management | 10% to 30% of total project cost, or $50 to $500+ per hour |
| Furniture & Lighting | Higher markup due to complexity, value, and management requirements | 30% to 40%, sometimes higher for custom pieces |
| Accessories | Lower markup as items are typically less expensive and easier to source | 20% to 30% |
| Cost-Plus Model | Materials charged at wholesale cost plus a fixed markup percentage | 10% to 20% markup on materials |
| Regional Variation | Metropolitan and luxury markets command higher markups than smaller markets | Urban areas: 35-50%; Smaller markets: 20-30% |
| Transparency Practice | Clear disclosure in contracts builds trust and manages client expectations | Inclusive pricing or separate line items with explanations |
What does markup percentage mean in the context of interior design services?
Markup percentage in interior design is the additional amount a designer adds on top of the wholesale or trade cost of products and materials purchased for a client's project.
This markup serves multiple purposes in an interior design business. It compensates the designer for the time spent sourcing products, managing vendor relationships, coordinating deliveries, and overseeing quality control throughout the procurement process. The markup also covers the designer's expertise in knowing where to find the best products at wholesale prices, which individual clients typically cannot access without trade credentials.
For example, if an interior designer purchases a sofa at a wholesale cost of $2,000 and applies a 35% markup, the client would be charged $2,700 for that sofa. The $700 difference represents the designer's compensation for finding, ordering, tracking, receiving, and delivering that piece to the client's home.
The markup percentage differs from a design fee, which compensates for creative work, consultations, and planning. Markup specifically relates to the procurement and management of physical products and materials.
What is the typical range of markup percentages applied by interior designers today?
Interior designers in 2025 typically apply markup percentages ranging from 20% to 40% on products and materials, with 35% being the industry standard.
The exact percentage depends on several factors including the designer's experience level, geographic location, target market, and business model. Entry-level designers or those in competitive markets may apply markups closer to 20-25%, while established designers with strong reputations can command markups of 35-40% or higher.
High-end luxury designers working with affluent clients often apply markups ranging from 40% to 60%, particularly on custom or specialty items. These higher markups reflect the designer's exclusive vendor relationships, ability to source rare or unique pieces, and the premium service expectations of luxury clientele.
Some designers use a tiered markup structure, applying different percentages based on the product's wholesale cost. For instance, they might apply 40% markup on items under $1,000, 35% on items between $1,000-$5,000, and 30% on items over $5,000.
This is one of the pricing strategies we break down in the interior designer business plan.
How does the markup percentage differ between products such as furniture, lighting, and accessories?
Markup percentages vary significantly across product categories, with furniture and lighting typically commanding higher markups than accessories in an interior design business.
| Product Category | Typical Markup Range | Rationale for Markup Level |
|---|---|---|
| Furniture | 30% to 40% | High-value items requiring extensive coordination, delivery management, potential assembly, and quality inspection. Custom furniture pieces may see markups of 40-50% due to the additional oversight and communication with fabricators. |
| Lighting Fixtures | 30% to 45% | Technical expertise required for specification, electrical compatibility assessment, and often professional installation coordination. Designer lighting from specialty vendors can command higher markups due to exclusive access and product knowledge. |
| Accessories | 20% to 35% | Lower individual value items that are easier to source and require less management. However, when accessories are curated from specialty boutiques or vintage sources, markups can reach 40%. |
| Window Treatments | 35% to 50% | Complex measurement requirements, custom fabrication coordination, installer management, and multiple fittings. The technical expertise and project management justify higher markups. |
| Fabrics & Textiles | 30% to 40% | Specialized knowledge of quality, durability, and appropriate applications. Coordination with workrooms and upholsterers adds management complexity. |
| Artwork | 20% to 40% | Variable markup depending on whether sourced from galleries (lower markup) or directly from artists (higher markup). Framing coordination and installation planning add value. |
| Custom Millwork | 35% to 50% | Extensive design development, technical drawings, contractor coordination, and multiple site visits required. The complexity and customization justify premium markups. |
How does the markup percentage for services differ from that for materials and products?
Service fees in interior design are structured differently from product markups and are typically charged as separate line items rather than as markups on the service itself.
Interior designers charge for their design services through several methods: hourly rates ranging from $50 to $500+ depending on experience and location, flat fees for defined project scopes, or percentage-based fees calculated as 10% to 30% of the total project cost. These service fees compensate for creative work, space planning, concept development, client meetings, and project management.
Product markups, on the other hand, specifically compensate for the procurement function—sourcing, ordering, tracking, and delivering physical items. A designer might charge a flat design fee of $15,000 for creative services and separately apply a 35% markup on $50,000 worth of furnishings, earning $17,500 from product procurement.
Some interior designers use a hybrid model where they charge reduced design fees (or no design fees) but apply higher product markups of 40-50%. Others charge full design fees and apply modest markups of 15-20%, essentially operating on a cost-plus basis.
The key difference is that service fees compensate for intellectual property and creative expertise, while product markups compensate for the logistics, relationships, and management involved in procurement.
What industry benchmarks or standards exist for markup percentages in interior design?
Industry benchmarks for interior design markup percentages are established through professional organizations and market practices, though they vary by market segment and region.
The American Society of Interior Designers (ASID) and the International Interior Design Association (IIDA) provide general guidance suggesting product markups between 25% and 35% as standard practice. However, these are recommendations rather than strict rules, and successful designers often adjust based on their specific business model and market positioning.
Cost-plus arrangements, where designers charge wholesale cost plus a fixed percentage, typically fall in the 10% to 20% range. This model offers more transparency to clients but generally results in lower total compensation compared to traditional markup models.
For design fees separate from product markups, industry benchmarks suggest 15% to 25% of total project cost for full-service residential projects. Commercial interior design projects often command lower percentage fees (10-15%) due to higher project values but may require more extensive documentation and coordination.
Hourly rate benchmarks vary significantly by experience level: junior designers typically charge $50-$100 per hour, mid-level designers charge $100-$200 per hour, and senior or principal designers can charge $200-$500+ per hour in major metropolitan markets.

How do regional or market differences influence the markup percentage an interior designer can apply?
Regional and market differences significantly impact the markup percentages interior designers can successfully apply, with metropolitan areas supporting higher markups than smaller markets.
Designers in major cities like New York, Los Angeles, San Francisco, Miami, and Chicago typically apply markups of 35% to 50% due to higher operating costs, more affluent clientele, and greater acceptance of premium pricing. These markets also have established design communities where industry-standard pricing is well understood and accepted by clients.
In secondary markets and suburban areas, competitive pressures and different client expectations often limit markups to 20% to 35%. Clients in these markets may have more price sensitivity and easier access to retail alternatives, making aggressive markup strategies less viable.
International markets show distinct patterns as well. European designers often work on lower product markups (15-25%) but charge higher design fees, while designers in emerging markets in Asia and Latin America may apply higher markups (40-60%) due to limited access to quality vendors and the premium placed on Western design expertise.
Luxury resort markets and affluent communities can support markups at the higher end of the spectrum regardless of geographic size, as the clientele in these areas expects premium service and is less price-sensitive.

What factors determine whether an interior designer chooses a higher or lower markup within the accepted range?
Several strategic and practical factors influence where an interior designer positions their markup percentage within the industry-accepted range.
Business model and positioning play the primary role: designers positioning themselves as luxury or boutique firms can justify markups of 40-50%, while those competing in value-conscious markets typically apply 20-30%. The designer's reputation, years of experience, portfolio quality, and brand recognition directly impact the markup clients will accept without resistance.
Project complexity and scope affect markup decisions. Large-scale projects with hundreds of items may use lower markups (25-30%) because the volume generates substantial revenue, while smaller projects with fewer pieces may require higher markups (35-45%) to ensure adequate compensation for the time invested.
Product sourcing difficulty influences markup levels. Items requiring extensive research, custom fabrication, overseas shipping, or specialty vendor relationships justify higher markups (40-50%), while readily available products from standard trade sources support moderate markups (25-35%).
Competition in the local market constrains markup flexibility. Markets with many designers competing for similar clients create downward pressure on pricing, while designers with unique expertise or exclusive vendor relationships can maintain premium markups.
The designer's overhead costs and target profit margins mathematically determine minimum viable markups. Designers with high-rent showrooms, large staff, and expensive marketing need higher markups to maintain profitability compared to solo practitioners working from home offices.
How do client expectations and budget levels affect the markup percentage applied?
Client expectations and budget constraints directly influence how interior designers structure and disclose their markup percentages.
High-budget clients with project values exceeding $100,000 typically expect and accept standard to premium markups (35-50%) because they prioritize quality, service, and the designer's expertise over price sensitivity. These clients value the convenience of having the designer manage all procurement and are willing to pay for that service through markups.
Mid-range clients with budgets between $25,000 and $100,000 are more price-conscious and often research product costs independently. For these clients, designers may apply moderate markups (25-35%) and emphasize the value proposition, explaining how their vendor relationships actually save money compared to retail purchases while providing superior service.
Budget-conscious clients with projects under $25,000 may resist traditional markup structures entirely. Designers serving this market often pivot to hourly billing ($75-$150 per hour) plus minimal markups (10-20%), or they charge flat design fees and allow clients to purchase directly from vendors, thereby eliminating the markup component.
Client sophistication also matters. First-time clients unfamiliar with interior design industry practices are more likely to accept standard markups without question, while repeat clients or those with previous design experience may negotiate or expect transparent cost-plus arrangements.
Trust level between designer and client affects markup acceptance. Long-term client relationships built on proven results and transparent communication support consistent markup application, while new client relationships may require more flexibility or detailed justification.
How do designers disclose or justify markup percentages to clients in contracts or proposals?
Interior designers use several approaches to disclose and justify markup percentages, balancing transparency with business viability.
The most transparent approach involves explicitly stating the markup percentage in the contract or proposal. For example, the agreement might specify "All furnishings and materials will be billed at wholesale cost plus 35% markup" or "Products will be charged at net cost plus a procurement fee of 30%." This approach builds trust but requires the designer to confidently defend their pricing structure.
Many designers use inclusive pricing, presenting clients with retail prices without explicitly breaking down the markup component. The contract language might state "All specified furnishings and materials at the prices indicated in the proposal" without disclosing wholesale costs. This approach is common and accepted but requires careful pricing to ensure competitive yet profitable margins.
Some designers describe markup as a "procurement fee" or "sourcing and management fee" rather than using the term "markup," which can have negative connotations. This reframing helps clients understand they're paying for a service—vendor coordination, quality control, delivery management—rather than just an arbitrary price increase.
Cost-plus arrangements provide maximum transparency by showing clients actual wholesale invoices and adding a fixed percentage (typically 15-20%). This method is increasingly popular with clients who value transparency but results in lower total compensation for designers.
Justification typically emphasizes the value delivered: access to trade-only vendors with products unavailable to the public, wholesale pricing that even with markup is competitive with retail, quality control and warranty management, coordination of deliveries and installations, and time savings for the client.
How does markup percentage compare to charging flat fees, hourly rates, or cost-plus arrangements?
Different pricing structures in interior design offer distinct advantages and disadvantages for both designers and clients.
| Pricing Method | How It Works | Advantages for Designer | Considerations |
|---|---|---|---|
| Markup Percentage | Add 20-50% to wholesale cost of products and materials | Revenue scales with project size; rewards efficient sourcing; compensates for product knowledge and vendor relationships | Requires confidentiality about wholesale costs; clients may perceive conflict of interest; profit varies with product selections |
| Flat Fee | Fixed price for defined scope, e.g., $25,000 for complete living room design and implementation | Predictable revenue; easy for clients to understand; rewards efficiency; no need to disclose product costs | Requires accurate scope definition; risk if project expands; must carefully estimate time and costs upfront |
| Hourly Rate | Charge $50-$500+ per hour for all time spent on project | Guaranteed compensation for all time invested; flexible for evolving projects; no financial risk from product selection | Clients may resist extensive hours; rewards slower work; requires detailed time tracking; income unpredictability |
| Cost-Plus | Bill actual wholesale cost plus 10-20% procurement fee | Maximum transparency builds trust; eliminates pricing objections; simpler accounting | Lower total compensation than traditional markup; must show wholesale invoices; less reward for finding better deals |
| Percentage of Project | Charge 10-30% of total project budget as design fee | Revenue scales with project value; clear expectations; common in commercial design | Requires accurate budget estimation; clients may reduce scope to lower fee; profit varies with actual spending |
| Hybrid Model | Combine methods, e.g., flat design fee plus reduced markup, or hourly rate plus cost-plus | Flexibility to optimize for different project types; can balance transparency with profitability; appeals to different client preferences | More complex to explain and administer; requires clear contract language to avoid confusion; must track multiple revenue streams |
| Retainer Model | Monthly fee for ongoing design services plus markup or cost-plus on products | Predictable recurring revenue; rewards long-term relationships; reduces sales cycle time | Best for established designers with repeat clients; requires consistent value delivery; limited applicability for one-time projects |
What risks are associated with setting markup percentages too high or too low in this industry?
Setting markup percentages outside the optimal range creates significant financial and reputational risks for interior designers.
Risks of excessively high markups (above 50% for standard products):
- Client dissatisfaction when they discover retail prices or wholesale sources independently, leading to trust erosion and potential contract disputes
- Loss of repeat business and referrals as clients feel overcharged compared to market norms or other designers
- Vulnerability to competition from designers offering more competitive pricing, especially in price-sensitive markets
- Negative online reviews and reputation damage in an era of price transparency and consumer research tools
- Legal and ethical concerns if markups are not disclosed and clients later feel deceived, potentially violating professional conduct standards
- Reduced project scope as high markups push total project costs beyond client budgets, resulting in smaller purchases and lower overall revenue
Risks of excessively low markups (below 20% for standard products):
- Inadequate compensation for time spent sourcing, ordering, tracking, and managing product procurement, leading to unprofitable projects
- Inability to cover business overhead costs including showroom rent, staff salaries, insurance, software subscriptions, and marketing expenses
- Unsustainable business model that cannot support growth, quality service delivery, or economic downturns
- Devaluation of the interior design profession by setting market expectations too low, making it difficult to raise prices later
- Insufficient cash flow to manage deposits, vendor payments, and project expenses, creating financial stress and credit problems
- Burnout from needing to take on excessive project volume to achieve income goals, compromising service quality and personal wellbeing
- Perception of low value or inexperience by potential clients who equate low prices with inferior service or lack of expertise
What best practices should an interior designer follow to calculate, apply, and communicate markup percentages effectively?
Successful interior designers follow systematic best practices for markup management to ensure profitability while maintaining client trust and satisfaction.
Calculating appropriate markups: Start by analyzing your true business costs including rent, utilities, insurance, software, marketing, staff salaries, and professional development. Calculate your hourly cost to operate the business, then determine how many billable hours you can realistically work per month. Use this data to establish minimum markup percentages that ensure profitability—typically this calculation reveals that 30-35% markup is necessary for sustainable operations. Track time spent on procurement activities (sourcing, ordering, coordinating, quality checks) to validate that your markup adequately compensates for these efforts.
Applying markups strategically: Develop a tiered markup structure based on product categories and price points rather than applying a single percentage across all items. Higher markups (40-50%) on accessories and smaller items compensate for proportionally higher handling time, while moderate markups (30-35%) on large furniture items remain competitive. Consider volume-based adjustments—large projects with many items can sustain slightly lower markups due to economies of scale. Apply premium markups (45-60%) on custom, unique, or hard-to-source items where your expertise adds exceptional value.
Communicating with transparency: Include clear pricing language in your contracts and proposals from the initial engagement. Decide whether to use transparent cost-plus language ("wholesale cost plus 30%") or inclusive pricing ("products at prices specified"), and apply this consistently. Explain the value clients receive through your markup: trade-only access, quality assurance, project management, warranty handling, and time savings. Provide written procurement agreements outlining how products will be priced before clients commit to the project.
Documentation and systems: Maintain detailed records of wholesale costs, applied markups, and final client prices for every product on every project. Use interior design software like Ivy, Design Manager, or Studio Designer to systematically track costs and automatically calculate markups. Create standardized pricing templates and formulas to ensure consistency across projects and team members. Document your markup rationale in internal notes to justify pricing decisions during client discussions or future reviews.
Market monitoring: Regularly research competitor pricing and market conditions in your area to ensure your markups remain competitive yet profitable. Survey 5-10 comparable designers annually to benchmark your pricing structure. Join professional organizations like ASID or IIDA to access industry research and participate in discussions about current pricing trends. Adjust markups gradually rather than making dramatic changes that shock existing or returning clients.
Client education: Proactively educate clients about how interior design pricing works during initial consultations, before they receive proposals. Explain that designers provide access to wholesale sources and the markup compensates for professional services beyond just product procurement. Share case studies demonstrating how your vendor relationships and expertise deliver value that exceeds the markup cost. Address pricing questions directly and confidently rather than appearing defensive or apologetic about your business model.
It's a key part of what we outline in the interior designer business plan.
Conclusion
Markup percentage in interior design is a fundamental business practice that typically ranges from 20% to 40% on products and materials, with 35% representing the industry standard in 2025.
