What Interior Designers Charge in India: Every Fee Model Explained

Interior designers in India charge in one of four ways in 2026: a design-only fee of ₹40–150 per sq ft of carpet area, a percentage of project cost, typically 8–15%, a lump-sum design fee of roughly ₹50,000–3 lakh for an apartment, or a turnkey model where the design fee is folded into the execution price. On a 1,100 sq ft 3 BHK with a ₹25 lakh execution budget, those models produce design fees between about ₹65,000 and ₹3.75 lakh for broadly similar deliverables. The model matters less than what it includes — drawings, revisions, site visits, and who buys the materials — so this guide prices all four and shows how to compare them on one page.

The four fee models, priced on the same home

Take a 1,100 sq ft carpet-area 3 BHK with interior works worth ₹25 lakh — close to the median home on our platform: ₹25.9 lakh across 68 completed AI estimates on HeyBuddy (Aug–Sep 2026). Here is what each model costs and covers.

Fee model	Typical 2026 range	Fee on this 3 BHK	Usually includes
Per sq ft (design only)	₹40–150/sq ft carpet	₹44,000–1,65,000	Layouts, 3D views, working drawings, material spec
Percentage of project	8–15% of execution cost	₹2,00,000–3,75,000	Design + vendor coordination + site supervision
Lump sum (design only)	₹50,000–3,00,000 per home	Fixed, scope-defined	Defined drawing set, capped revisions
Turnkey / design-build	Fee inside the project price	Not shown separately	Design, execution, warranty under one contract

Two honest caveats. First, ranges are wide because seniority is priced in: a young independent designer at ₹40–60 per sq ft and an established studio at ₹120–150 are both quoting fairly. Second, in the turnkey model you are still paying for design — it is simply invisible, spread across execution line items.

Per sq ft: the Bangalore default

The per-sq-ft model dominates among independent designers in Bangalore. It scales with home size, not with how much you spend on materials, which keeps the incentive clean: the designer earns the same whether you pick laminate or veneer.

Ask three questions before signing: which area is being measured (carpet, not super built-up — the difference is 20–30% of the fee), how many revision rounds are included, and whether site visits during execution are in the fee or billed at ₹2,000–5,000 per visit. A quoted ₹60 per sq ft with unlimited paid visits can end up costing more than ₹100 per sq ft all-inclusive.

Percentage of project: supervision built in, incentive not clean

At 8–15% of execution cost, this model bundles design with vendor management and site supervision — genuinely valuable on a full-home job where someone must chase the carpenter, the painter and the electrician in the right order.

Its known weakness: the fee grows when your budget grows, so the designer has a structural nudge towards costlier materials. Manage it by fixing the percentage against a written budget cap agreed upfront, with the fee frozen if the budget rises at the designer's suggestion rather than yours. Also confirm whether the percentage applies to the pre-GST or post-GST project value; on a ₹25 lakh project that difference alone is worth ₹36,000–67,000.

Lump sum: certainty, if the scope is written down

A fixed design fee works well when you know your scope: a defined drawing set, a fixed number of 3D views, two or three revision rounds. It is the easiest model to compare across designers — but only if the deliverables list is written into the agreement. The classic failure is a ₹80,000 lump sum that turns out to cover two rooms in 3D and "concept only" for the rest.

Turnkey: one contract, one warranty, one markup

Design-build firms quote you a single project price with design inside it. You give up fee transparency and gain a single point of accountability — no designer-blames-contractor loop. The design cost has not vanished; assume roughly 5–10% of the contract value is effectively the design and management layer. The document that matters here is not the fee but the quotation itself: read every section of it the way we lay out in how to read an interior design quotation, because with turnkey, material grades are where margins hide.

City colour: Bangalore vs Noida vs Ghaziabad

Bangalore skews per-sq-ft and design-only, with a deep bench of independents; ₹50–120 per sq ft covers most of the market, and you can browse verified interior designers in Bangalore to see the spread. Noida leans percentage and turnkey — buyers taking possession in high-rise sectors mostly want one firm to handle everything, and designers in Noida quote accordingly. Ghaziabad pricing runs a shade under Noida for the same spec, mostly on labour rates; designers in Ghaziabad frequently serve Indirapuram and Vaishali at Noida-quality output with 10–15% friendlier execution costs.

How to compare quotes across different models

Designers will quote you in different currencies — per sq ft, percentage, lump sum. Convert everything to two rupee figures before deciding:

1. Total design fee in rupees, on your carpet area and your realistic budget. Use a neutral number for that budget, not the designer's — the interior cost calculator gives you a fair execution estimate for your floor plan to anchor the percentage models.
2. Cost per included deliverable. Count drawings, 3D views, revision rounds, site visits, and supervision months. A ₹1.5 lakh fee with supervision included routinely beats a ₹75,000 fee plus paid visits and a mid-project abandonment.

Then check the exclusions in writing: structural or MEP drawings, liaison with the society or builder, and purchase accompaniment are commonly extra. Finally, ask how the designer's fee interacts with execution — if they take a commission from vendors they recommend, you want that declared, because you are paying it either way.

Frequently asked questions

How much does an interior designer charge for a 3 BHK in India?

For design alone, expect ₹40–150 per sq ft of carpet area or a lump sum of roughly ₹50,000–3 lakh in 2026, depending on the designer's seniority and city. If supervision is included via a percentage model, budget 8–15% of the execution cost. On a typical 1,100 sq ft 3 BHK that means a total design outlay between about ₹65,000 and ₹3.75 lakh.

Is a percentage fee better than a per sq ft fee?

Percentage fees include vendor coordination and site supervision, which per-sq-ft design-only fees usually do not — so they suit full-home projects where you cannot visit site weekly. Their weakness is incentive: the fee rises with your spend. Fix the percentage against a written budget cap, and confirm it applies to the pre-GST value, before signing.

Do interior designers charge for the first consultation?

Practice varies. Many independents and most design-build firms offer the first meeting free as a sales conversation; established studios often charge ₹2,000–10,000, sometimes adjustable against the fee if you sign. What matters more is what the first paid milestone buys — insist on seeing a deliverables list (layouts, 3D views, revision rounds) before paying any design advance.

Are design charges separate from the execution quotation?

In design-only and percentage models, yes — you pay the designer a fee and pay contractors separately against their own quotation. In turnkey design-build, one contract covers both and the design cost sits inside the project price. Either way, always get an itemised execution quotation; the design fee is rarely where money is lost, the material grades are.
