Pricing is where most studios quietly lose money. Not on site. Not in procurement. Right at the quote stage, before a single nail goes in.
I've watched brilliant designers hand over a beautiful mood board and then fumble the number. They either lowball to win the job and bleed for six months, or they throw a scary round figure at the client with no logic behind it and lose the deal. Both hurt. Both are avoidable.
So let's talk plainly about how to price interior projects in rupees. Not theory. The actual mechanics: what you charge for your brain, what you charge for the stuff, and how you keep margin instead of watching it leak away by the time the project closes.
Two things you're actually selling
Every interior project is two businesses stitched together, and you have to price them separately in your head even if the client sees one number.
One is your design fee, the value of your thinking. Space planning, layout, the 3D views, material selection, the coordination, the site visits. This is your time and your taste. It has nothing to do with how expensive the sofa is.
The other is execution, the physical delivery. Carpentry, false ceiling, electrical, painting, furniture, soft furnishings, the labour, the vendors. Here you're not selling your brain, you're selling procurement and project management. And on this part you earn through a markup on cost.
The moment you mix these two into one fuzzy "package price," you lose the ability to see where you're making money and where you're subsidising the client. Keep them mentally separate always.
Design fee: how to actually set it
There are three common ways studios in India charge the design fee, and each has a place.
- Per square foot. You quote something like ₹80 to ₹250 per sq ft of design fee depending on the scope and your positioning. A 1,200 sq ft flat at ₹150/sq ft is ₹1.8 lakh in design fee. Simple, easy to explain, client understands it.
- Percentage of project cost. You take a slice, often 8% to 15%, of the total execution budget. Sounds neat, but it has a trap: it punishes you for being efficient and rewards you for making the project expensive. It also collapses the second a client says "I'll buy the furniture myself."
- Flat fee per scope. You define the deliverables, say, full design of a 3BHK including drawings, 3D, and material board, and quote one fixed number. Cleanest for the client, but you must scope it tightly or you'll do endless revisions for free.
My honest take: for most residential work, per-square-foot or a well-scoped flat fee protects you better than a raw percentage. I've written a longer breakdown of this in Design Fee vs Percentage of Cost: How to Charge in India, worth reading if you're stuck choosing.
Whatever you pick, the design fee must cover your studio's actual cost of delivering that thinking. Add up designer hours, your time, software, overheads, and put a real margin on top. If you can't say what one designer-hour costs your studio, you're guessing, and guessing is how you end up doing a ₹1.8 lakh project that cost you ₹1.9 lakh to deliver.
Execution markup: where the real money and the real leaks live
Execution is a bigger number and a scarier one, because it's mostly other people's money passing through your books.
The standard model: you get vendor and labour costs, you add a markup, that becomes the client price. A modular kitchen that costs you ₹2.4 lakh from your carpenter goes to the client at, say, ₹3 lakh, a 25% markup, ₹60,000 gross to you on that one line.
Here's the thing nobody tells you at the start. Your quoted margin is never your final margin. Between the quote and the closing invoice, it erodes. Vendor rates go up mid-project. The client changes the laminate three times. There's a site rework because a measurement was off. A material you quoted at last month's rate now costs 8% more. Every one of these eats the ₹60,000 you thought you'd made.
So you don't just apply a markup and hope. You build in a buffer and you defend it. A few rules I live by:
- Never quote from memory. Get a fresh vendor rate before every quote. GST rates on materials shift, plywood and hardware prices move, and a three-month-old rate card will quietly sink you.
- Mark up on your real landed cost, including transport, wastage, and GST input reality, not the vendor's headline sticker price.
- Keep a contingency line, even 5% to 8%, that's yours to absorb the small overruns without renegotiating with a nervous client.
- Lock the scope in writing. "Client-requested changes after sign-off are chargeable" is one sentence that saves lakhs across a year.
I go deep on this in How to Protect Your Margin on Every Design Project, because this single discipline separates studios that grow from studios that stay busy and broke.
A simple way to build a quote in rupees
Let me make it concrete. A 2BHK, 1,000 sq ft, full interiors.
Design fee: 1,000 sq ft × ₹150 = ₹1,50,000. This is your thinking, invoiced separately.
Execution, room by room:
- Modular kitchen, cost ₹2,20,000, markup 25% → client ₹2,75,000
- Wardrobes (2 bedrooms), cost ₹1,80,000, markup 22% → client ₹2,19,600
- False ceiling + electrical, cost ₹1,40,000, markup 20% → client ₹1,68,000
- Painting, cost ₹90,000, markup 18% → client ₹1,06,200
- Furniture + soft furnishings, cost ₹1,50,000, markup 25% → client ₹1,87,500
Add execution cost ₹7,80,000, execution client price ₹9,56,300, so your execution gross is about ₹1,76,300. Add the ₹1,50,000 design fee on top. Now you can see exactly where your money comes from, line by line, room by room.
This is also why room-by-room specs matter so much. When your quote is built from actual furniture and finish specs per room, not one vague lump, you can price accurately, defend every number, and spot the leak the moment a vendor rate changes. Doing this on paper or a messy Excel is where mistakes creep in. Doing it in one connected workspace, where the spec becomes the quote and the quote becomes the invoice, is how you stop the bleed. That's exactly what we built Designa to do.
Then comes the boring part that decides whether you actually get paid
A great quote that never becomes a proper GST invoice is just a nice PDF. In India, your quote has to convert cleanly into a compliant tax invoice, right HSN codes, right GST split, right numbering, and it has to be collectable via Razorpay or bank transfer without three follow-up calls.
Where studios lose money here is the gap between quote and invoice. Numbers get re-typed, a line gets missed, GST gets calculated wrong, and suddenly your ₹1,76,300 margin is ₹1,60,000 because of a data-entry slip. I wrote about closing that gap in How to Turn a Quote Into a GST Invoice in Minutes, when the quote and the invoice are the same living document, that leak disappears.
And if you've been running the same rates for three years while your rent, salaries, and material costs all went up, you're the one funding the client's project. Raising prices feels terrifying but it's usually overdue, How to Raise Your Design Prices Without Losing Clients walks through doing it without the panic.
The margin leaks hiding in plain sight
Even with clean pricing, money escapes in small, boring ways: unbilled site variations, free revisions, procurement rate changes you forgot to pass on, scope creep nobody logged. Individually they look tiny. Across a year of projects they add up to a designer's salary. If you want the full list, I catalogued them in 7 Places Your Design Studio Quietly Leaks Margin.
The fix for almost all of them is the same: one connected system where the spec, the quote, the purchase orders, and the invoice all talk to each other, so a change in one place updates everywhere and nothing slips through.
Your quick checklist
- Separate the design fee from the execution markup, always, even if the client sees one number.
- Set your design fee from your real cost per designer-hour, not a gut figure.
- Quote execution from fresh, landed vendor rates including GST reality.
- Build a 5-8% contingency and lock scope in writing.
- Make the quote become the GST invoice, don't re-type numbers.
- Review your rates every year.
Pricing isn't a dark art. It's arithmetic plus discipline. Get the two halves right, defend the margin between quote and close, and you'll finally keep what you earn.
