How Interior Designers Price and Mark Up Window Treatments: The Complete Guide

Why Pricing Window Treatments Is Different from Pricing Furniture

Window treatments occupy a unique position in the interior designer's product mix. Unlike a sofa, which arrives and is done, a window treatment involves multiple professional touchpoints: site measurement, fabric selection and sampling, workroom coordination, lead-time management, installation scheduling, and often post-installation adjustment. Each of those steps carries real labor cost — most of which designers historically have not charged for explicitly. The markup on goods is, in part, how that invisible labor gets compensated.

The complexity of window treatment pricing is compounded by the sheer number of cost variables: fabric at anywhere from $12 to $400 per yard, fabrication fees from workrooms ($85–$400 per panel), hardware at $30–$600 per window, and installation typically running $75–$200 per window depending on the market. Designers who don't have a systematic approach to building and presenting these costs often underprice their work significantly — and feel burned when a project barely breaks even.

This guide walks through the full pricing architecture that working designers use: how to access trade pricing, how to structure markups, how to present costs to clients transparently, and how to protect your margin when vendor prices shift mid-project.

Understanding Trade Account Pricing

A trade account is a business relationship between a designer and a supplier that grants access to wholesale or near-wholesale pricing in exchange for proof of professional status. Most major window treatment vendors — including Kravet, Fabricut, Schumacher, Robert Allen, Duralee, and specialty workroom suppliers — maintain structured trade programs with tiered discount schedules.

The baseline trade discount from most fabric houses is 50% off the retail (list) price, referred to as a "50% net" or "50-off" account. On higher-volume accounts, some houses offer further reductions — 50/10 (50% off list, then an additional 10% off net) or occasional seasonal discounts of an additional 15%. Hardware vendors like Kravet Hardware, Samuel and Sons, and Fabricut's hardware division typically run trade at 40–50% off list. Workrooms, which fabricate the treatments, don't offer retail pricing at all — they sell exclusively to the trade at prices typically ranging from $90 to $250 per panel for drapery, depending on fullness and complexity.

Markup Models: Net Cost vs. Retail Reference

There are two primary frameworks designers use when marking up window treatments for clients, and understanding the math behind both is essential before choosing your approach.

The net cost markup model starts with your actual out-of-pocket cost (fabric at trade price, workroom fee, hardware at trade) and adds a percentage on top. A 35% markup on a $600 net cost yields a client price of $810. A 50% markup on the same job yields $900. This model is transparent and defensible — you know exactly what you paid and what you're charging.

The retail reference model presents the client with a discounted price relative to retail. If a fabric retails for $180/yard and you have it at $90 net, you might present it to the client at $135/yard — 25% off retail, but a 50% markup on your cost. This model can create the perception of client savings while still delivering solid margin. However, in the age of Google, clients can often find retail prices in three minutes, so transparency is increasingly important.

Markup Model	Your Net Cost	Markup %	Client Invoice Price	Designer Margin
Net Cost + 20%	$600	20%	$720	$120
Net Cost + 35%	$600	35%	$810	$210
Net Cost + 50%	$600	50%	$900	$300
Net Cost + 65%	$600	65%	$990	$390
Retail Reference (30% off retail)	$600 net / $1,200 retail	N/A	$840	$240

 

Industry-Standard Markup Ranges by Window Treatment Category

Markup percentages in the window treatment category vary by product type, price point, and how much design and project management time is embedded in the sourcing process. Below are the ranges most consistently applied by experienced residential designers as of 2025.

Product Category	Typical Net Cost Range	Standard Markup Range	Notes
Custom drapery panels	$200–$600/panel net	35–50%	Higher markup justified by workroom coordination
Roman shades (custom)	$180–$450/shade net	35–45%	Fabrication complexity warrants premium
Motorized roller shades	$300–$900/shade net	25–40%	Tech component; client expects transparency
Hardware & rods	$50–$400/window net	40–60%	Often undercharged — price assertively
Fabric (designer grade)	$25–$100/yard net	40–55%	Standard across the trade
Sheers & casuals	$80–$250/panel net	30–45%	Lower complexity = slightly lower markup
Woven wood shades	$150–$400/shade net	30–45%	Competitive; watch retail comparison pricing
Installation (pass-through)	$75–$200/window	10–20%	Administrative markup on subcontractor cost

 

How to Structure a Window Treatment Proposal for Clients

The way you present window treatment pricing to clients shapes both their perception of value and your ability to hold your margin when questions arise. The most professional — and defensible — proposal format presents each window as a line item with its component costs summarized, rather than exposing fabric yardage and workroom rates as separate rows.

A well-structured window treatment proposal includes: the room and window location, the treatment type and fabric specified (name, colorway, and width), the estimated yardage required, the total client investment for that window, and the lead time. What it does not expose is your trade pricing or workroom net. You're not hiding information — you're presenting your professional services and their output, just as a contractor presents a quote rather than a cost-plus breakdown.

Sample Proposal Line Item Format

Living Room / Window 1 — Custom Pinch Pleat Drapery: Kravet Bellamy 36107-5 in Linen (60" wide), 118" finished length, 2.5x fullness on Kravet 3" Diameter Wood Rod in Alabaster. Includes fabrication, hardware, and installation. Investment: $1,840.

This format communicates professionalism, gives the client enough specificity to understand what they're approving, and does not require you to defend your trade pricing. The client is buying a completed, installed window treatment — not buying fabric by the yard.

How to Handle the Budget Conversation Around Window Treatments

Most first-time clients underestimate window treatment costs by 40–60%. They've seen a set of curtains at Target for $79 and cannot understand how a single window in their living room could cost $1,800. Part of your job — and part of the value you bring — is educating them on what they're actually buying.

The most effective framing is to anchor the conversation to cost-per-year rather than total project cost. A $2,200 window treatment that lasts 15–20 years costs roughly $140 per year — less than most homeowners spend on shoes or dining out in a month. Custom treatments outlast the house trends they're designed within, and they do a job no $79 panel can: they fit, they hang properly, they block what they're supposed to block, and they look correct from the street.

When a client pushes back on pricing, the worst move is to reduce your markup. The right move is to adjust the specification: move from a $95/yard designer fabric to a $45/yard fabric from the same house, or from a custom roman shade to a semi-custom shade with a shorter lead time. This preserves your margin while giving the client a path to a lower total investment.

Step-by-Step: How to Price a Window Treatment Project

1.     Step 1 — Measure First: Conduct a full site measure and photograph every window to be treated. Note height from floor to ceiling, width of window opening, ceiling height, any architectural complications (moldings, recesses, sloped ceilings).

2.     Step 2 — Calculate Yardage: Calculate fabric yardage for each treatment using the standard formula: (finished width × fullness) ÷ fabric width × (finished length + hem and header allowance) ÷ 36. Add 10–15% for pattern repeat matching on prints.

3.     Step 3 — Get Workroom Quotes: Request pricing from your workroom for each treatment type. Get a line-item quote: fabrication per panel or shade, lining costs, interlining if specified, and any specialty construction such as leading edge detail or custom header.

4.     Step 4 — Price Hardware: Price out hardware at trade. Calculate rod length needed (typically window width plus 6–12" each side for returns), number of rings or carriers, brackets, and any specialty fittings for bay windows or corner windows.

5.     Step 5 — Apply Markup: Add your markup consistently to every component: fabric, fabrication, hardware, and installation (typically a 10–20% administrative markup on your installer's invoice). Build the full window investment price.

6.     Step 6 — Build the Proposal: Compile the proposal in your standard format. Present by window location, not by component. Include a summary investment total for the full project and a separate page showing payment schedule and deposit terms.

7.     Step 7 — Include Lead Times: Present with lead-time expectations built in from the start. Reference your current workroom production schedule — if custom drapery is running 10–12 weeks, state that in the proposal so the timeline is part of the approval, not a surprise later.

8.     Step 8 — Collect Deposit: Collect a deposit of 50% at contract signing. Remaining 50% is due prior to installation or upon delivery of goods. Do not order fabric or place workroom orders without a signed agreement and deposit in hand.

Disclosure Requirements and Professional Ethics

The interior design industry does not have a single uniform disclosure standard for trade pricing, but best practices — and increasingly, client expectations — point toward transparency. The ASID and NCIDQ both recommend that designers disclose their compensation model, including whether they markup goods, at the start of a client engagement. This disclosure should appear in your contract or letter of agreement.

What you do not need to disclose is your exact trade pricing. You are not required to show a client your Kravet invoice. You are required to disclose that you are marking up goods and approximately what your markup model looks like. A simple sentence in your contract — 'Products are sourced at trade pricing and invoiced at designer's retail, which includes a professional markup of 30–40%' — provides protection without requiring you to expose your vendor relationships.

Designers who are fully transparent about their markup structure consistently report that clients accept it. Clients who discover hidden markups — particularly when they find the retail price online and realize they paid above it — typically do not return. Transparency is not just ethical; it's good business.

Protecting Your Margin When Prices Change Mid-Project

Fabric prices at most houses are updated annually, with most increases taking effect in January. If a client approves a proposal in November and your fabric price increases 8% in January before the order ships, you have two choices: absorb the increase or pass it through. Your contract should address this scenario explicitly.

The standard professional clause reads something like: 'All pricing is valid for 30 days from proposal date. Orders placed after this period are subject to current pricing.' Include this language, enforce it, and avoid surprises by placing orders quickly after deposit receipt.

Workroom prices also fluctuate, particularly when demand is high. If your workroom raises rates between the quote and the fabrication date, build in a 5–10% contingency buffer in your initial proposal to absorb minor increases without a client conversation.

Frequently Asked Questions

What is a standard markup for window treatments?

Most experienced residential designers apply a markup of 35–50% on net (trade) cost for window treatment goods. The specific percentage varies by product type, project complexity, and how much project management time is embedded in the service. Hardware and installation pass-through costs are typically marked up 10–40%. The key is consistency — use the same markup logic across all categories within a project, and document it in your contract.

Do interior designers have to disclose their markup to clients?

There is no universal legal requirement to disclose exact markup percentages, but professional organizations including ASID recommend transparency about your compensation model. Your contract should state that goods are sourced at trade pricing and invoiced with a professional markup. You do not need to show clients your invoices, but you should not misrepresent how you are compensated. Transparency builds long-term client relationships; hidden markups destroy them.

Can a client buy window treatments through a designer's trade account?

No. Trade accounts are registered to the design business and are not transferable to clients. Vendors explicitly prohibit resale of trade-priced goods to end consumers outside of a design project relationship. If a client wants to purchase directly, they must do so at retail through the vendor's consumer channel — which in many cases doesn't even exist, as workroom-grade fabrics are trade-only. This is a legitimate reason why clients benefit from working through a designer.

How do I explain my markup to a client who pushes back?

Frame the markup as part of your professional service model, not as a surcharge. You are not simply ordering fabric — you are managing vendor relationships, coordinating with workrooms, tracking lead times, scheduling installation, and warrantying the result. The product markup covers that management layer. You can also compare to other professional service models: a contractor doesn't just charge labor on materials; they mark up materials because managing the supply chain is part of what they do.

What discount do designers get on window treatment fabric?

Most established design trade programs offer 50% off list (retail) price on fabric. Some premium accounts at high-volume houses receive an additional 10% off net (written as 50/10 in the trade). Hardware discounts typically run 40–50% off retail. These discounts reflect the volume, professional reliability, and relationship that trade accounts represent — they are not available to consumers.

Should I markup installation on top of the installer's fee?

Yes. Scheduling, coordinating, supervising, and warrantying installation is professional work that takes your time. A 10–20% administrative markup on installation is standard and defensible. Include it as a line item in your proposal labeled 'Installation Coordination' or simply fold it into your installation line at your marked-up rate. If the installer charges $150/window, billing $175–$180 is entirely appropriate.

What happens if fabric is discontinued after a client approves it?

This happens more often than anyone wants. Your contract should include a fabric availability clause stating that all selections are subject to availability at time of order. When a fabric is discontinued, you must notify the client immediately and present a substitution. If the substitution is less expensive, the client should receive the benefit. If it's more expensive, that's a change order conversation. Move quickly — the longer you wait, the more trust erodes.

How do I price window treatments for a whole-house project?

Build a room-by-room window schedule in a spreadsheet: every window, its proposed treatment type, fabric specification, and estimated investment. Sum by room, then by project. This gives you a complete picture before presenting to the client, and lets you identify where adjustments can be made if the total exceeds budget. Present the full number early — surprises late in a project are far more damaging to the client relationship than an honest total at the start.

Working with Workroom Partners: The Hidden Cost Center in Window Treatment Projects

No discussion of window treatment pricing is complete without addressing the workroom — the skilled fabrication shop that actually sews your specified treatments. Most designers have a single primary workroom and one or two backup relationships, and the quality and cost of that workroom relationship shapes everything about how window treatment projects are priced and managed.

Workroom pricing is not standardized. Two workrooms in the same city, working in the same week, can quote meaningfully different prices for an identical specification — a 2.5x fullness inverted pleat panel in a medium-weight linen. The higher price may reflect longer production time, more experienced seamstresses, better quality control, faster turnaround, or simply a different cost structure. The lowest price is rarely the right choice in a high-visibility residential project.

Understanding how to read and compare workroom quotes is a skill that saves designers real money and protects project margins. The standard line items in a workroom quote include: fabrication per panel (the base rate for cutting and sewing), lining charge per panel (the additional cost when a lining beyond the standard is specified), special heading charges (goblet pleats, leading edge detail, and other non-standard constructions typically carry a premium of $15–$50 per panel), and pressing and packaging charges (some workrooms charge separately for professional steaming and delivery-ready packaging).

When you receive a workroom quote, review it against your specification sheet line by line. A workroom that quotes $110 per panel for a straightforward pinch-pleat panel is not out of line in a major US market. A workroom that quotes $220 for the same spec should be asked to explain the difference. There may be a legitimate reason — production queue timing, specialty pressing equipment, higher-grade thread — or there may simply be an error or a mismatch in what was quoted versus what was specified.

Managing Change Orders in Window Treatment Projects

Change orders are the silent margin killer in window treatment projects. A client who changes a fabric selection after the order has been placed at the mill triggers a cascade of costs: restocking fees (typically 25–40% of the ordered yardage value at most trade houses), potential workroom re-quoting if the new fabric has different fabrication requirements, and the labor time required to process the change administratively. These costs are real, and they need to be passed through to the client — not absorbed by the designer.

Your contract should include an explicit change order clause: any fabric, specification, or timeline change after the client-approved proposal triggers a change order with associated fees, documented and collected before work resumes on the changed item. The standard restocking fee at Kravet is 25% of the net value of the returned goods. At Schumacher, it is 30%. These fees exist regardless of whether the fabric has shipped — once an order is cut, the house has committed to that yardage.

The practical protection against change orders is decision-making rigor at the approval stage. Do not release a fabric or hardware order until you have a written, signed approval from the client. 'She texted that she loves it' is not an approval. Email approval with the specific fabric name, colorway, and quantity attached is the minimum standard. This single habit prevents the majority of post-order change requests, because clients who have reviewed and signed off in writing are significantly less likely to second-guess their decision.
