Common Interior Design Expenses: Complete Cost Breakdown
Interior design is more than furniture and décor. A realistic budget brings together design, materials, carpentry, kitchen and wardrobe work, lighting, finishes, labour, installation and the smaller costs that are easy to miss.
Plan Your Interior BudgetDesign & professional fees
Design fees pay for the thinking and coordination behind the project: layouts, concepts, 2D drawings, 3D visualization, material and colour selection and site supervision.
Carpentry, modular furniture & custom work
Carpentry and modular furniture can become one of the largest parts of a home interior budget because they combine material, hardware, manufacturing and installation.
Modular kitchen
The current guide gives a planning range of ₹1.5 lakh–₹4 lakh, depending on size, materials, hardware, accessories and customization.
Wardrobes & storage
The guide cites ₹60,000–₹1.5 lakh per room as a typical planning range, with finish, size, internals and hardware affecting the final amount.
Custom furniture
TV units, shelving, study tables and other custom pieces vary substantially according to design, dimensions, material and finish.
Kitchen, wardrobes & hardware
A quotation should identify the kitchen and wardrobe scope clearly. Compare carcass, shutters, hardware, accessories, countertop, internal storage and installation rather than comparing only a headline price.
- Kitchen size and layout
- Carcass and shutter material
- Hinges, channels and lift-up hardware
- Countertop and backsplash scope
- Wardrobe quantity and internal accessories
- Installation, transport and finishing
Ceilings, lighting, flooring & walls
False ceiling & lighting
The guide estimates ₹80–₹200 per sq. ft. for false ceiling and lighting-related work, depending on the specification.
- Gypsum or POP ceiling
- Cove lighting and LED strips
- Decorative fixtures
Flooring & wall finishes
Published planning guidance puts this category at ₹60,000–₹3 lakh+, depending on the materials and area.
- Vitrified tiles
- Wooden flooring
- Marble or granite
- Paint, wallpaper and panels
Soft furnishings & décor
The guide cites ₹30,000–₹2 lakh+ for soft furnishings, with curtains, upholstery, rugs, bedding and décor affecting the total.
Electrical, appliances, décor & installation
Some expenses sit outside visible carpentry but can materially change the final budget.
- Electrical & appliances: switches, sockets, fans, air conditioners, kitchen appliances and smart-home systems.
- Décor: mirrors, art, decorative lighting, plants and accessories.
- Labour & installation: carpentry installation, electrical and plumbing labour, painting, finishing, transport and handling.
Labour reference: the current guide says labour typically accounts for 10–20% of total interior cost, depending on execution complexity and location.
