Compare Interior Quotations Using the Same Area and Scope
One interior contractor quotes ₹1,200 per sq ft. Another quotes ₹1,800. Which offers better value?
The answer depends on what each rate measures and includes.
The lower figure might cover selected cabinetry, while the higher figure includes furniture, painting, electrical work and installation. Even the area used to calculate the total may differ.
Per sq ft pricing is a fair comparison only when both quotations use the same measurement basis, scope, quantities and specifications. Otherwise, the rates can give a misleading impression of cost.
This guide explains how to use per sq ft prices without losing sight of the complete project.
What Does Per Sq Ft Pricing Mean in Interiors?
A per sq ft rate expresses a price against a measured area. In interior work, that area can refer to several different things.
| Measurement basis | What it measures | What to clarify |
|---|---|---|
| Apartment carpet area | The apartment’s carpet-area figure | Which work the rate covers |
| Built-up or saleable area | A different property-area figure | The exact area and its source |
| Cabinet frontage | The front-facing width × height | Depth, interiors, hardware and lofts |
| Painted surface area | Walls or ceilings being painted | Preparation, products and application scope |
| False-ceiling area | The measured ceiling work | Treatment of drops, coves and additional details |
A wardrobe rate and a whole-apartment rate may both use “per sq ft” while describing entirely different measurements.
Always ask: “Per square foot of what?”
When Is Per Sq Ft Pricing Useful?
Per sq ft pricing can help with an early budget discussion or a comparison of clearly specified work.
It is useful when:
- The measured area is agreed.
- Both vendors price the same scope.
- Material and hardware specifications match.
- Installation and other charges receive the same treatment.
- Exclusions are clearly listed.
It can also help summarise a completed estimate:
Effective project rate = Total project cost ÷ Agreed apartment area
However, this summary does not explain how the money is distributed between rooms or items. Keep the detailed quotation alongside it.
How Can a Lower Rate Produce a Higher Total?
Consider this hypothetical example, where both vendors price the same scope but use different apartment-area figures:
| Calculation | Quote A | Quote B |
|---|---|---|
| Advertised rate | ₹1,200 per sq ft | ₹1,500 per sq ft |
| Area used | 1,500 sq ft | 1,100 sq ft |
| Calculated amount | ₹18,00,000 | ₹16,50,000 |
Quote A has the lower rate but the higher total.
This does not prove either vendor is overcharging. It shows why you need to establish the measurement basis before comparing prices.
Ask both vendors to provide the final amount for the same agreed requirements.
Why Can Two Similar Apartments Have Different Rates?
Different Furniture Quantities
One household may need three large wardrobes, several study units and extensive kitchen storage. Another may retain existing furniture.
Dividing both project totals by a similar apartment area will produce different rates.
Different Materials and Hardware
Cabinet materials, shutter finishes, drawer systems, hinges and accessories affect the quotation.
A label such as “premium finish” is too broad for a reliable comparison. Request the actual specifications.
Different Site Conditions
An existing home may need dismantling, surface repairs or service changes.
These costs can raise the effective project rate even if the new furniture is relatively simple.
Different Levels of Service
Measurement visits, detailed drawings, coordination, supervision and after-sales support may be included in one proposal and excluded from another.
Compare those commitments as part of the price.
How Should You Compare Wardrobe Prices Per Sq Ft?
Wardrobes show why a rate alone is insufficient.
An illustrative wardrobe measuring 8 feet wide and 7 feet high has a frontage of:
8 × 7 = 56 sq ft
At an illustrative rate of ₹1,500 per frontage sq ft, the calculated price would be:
56 × ₹1,500 = ₹84,000
Before accepting that amount, confirm what it buys.
| Wardrobe detail | What to record |
|---|---|
| Dimensions | Width, height and depth |
| Cabinet structure | Material, grade and thickness |
| Shutters | Material, finish and opening type |
| Internal arrangement | Shelves, hanging sections and drawers |
| Hardware | Brand, model or agreed specification |
| Lofts | Included or separately measured |
| Additional features | Mirrors, lights and accessories |
| Installation | Delivery, fitting and site adjustments |
Two wardrobes with the same frontage can contain very different amounts of material and hardware.
The figures above demonstrate the calculation only; they are not market-rate recommendations.
What Should You Request Instead of a Single Rate?
Ask for an itemised bill of quantities, often called a BOQ.
It should identify each item, its measurement or quantity, specification, rate and amount. For fixed-price items, the description should still explain the included work.
A useful quotation allows you to answer:
- How many units am I buying?
- What are their dimensions?
- Which materials and fittings will be used?
- What labour and installation are included?
- Which expenses remain outside the total?
You can then use the overall per sq ft figure as a summary rather than the sole basis for choosing a vendor.
How Do You Compare Two Interior Quotations Fairly?
- Share the Same Requirement List
Give both vendors the same layout, room requirements and retained-furniture list.
Identify essential work and optional features separately. 2. Confirm the Measurement Method
Ask how apartment area, cabinetry, painting and ceiling work are measured.
Resolve differences before comparing rates. 3. Match Specifications
Check materials, dimensions, internal fittings, finishes and hardware.
Where vendors propose alternatives, ask them to explain the difference and provide an equivalent option where possible. 4. Add Excluded Costs
Include required delivery, installation, electrical work, fittings, taxes and other expenses omitted from the initial figure.
Compare the final payable amount for equivalent work. 5. Separate Estimates from Fixed Prices
Identify allowances for items that have not yet been selected.
Ask how the price changes if your final choice costs more or less than the allowance. 6. Document Changes
Agree on how additions, substitutions and removed items will affect the total.
Request written approval of the price change before work proceeds.
Does a Higher Per Sq Ft Rate Mean You Are Being Overcharged?
No. A higher rate may reflect more work, better-specified components or a broader service commitment.
Equally, a lower rate may be competitive or may leave important items outside the quotation.
Ask the vendor to explain substantial differences. If you still cannot reconcile them, obtain another quotation using the same brief.
Negotiation becomes more productive when you discuss specific units, materials and services rather than asking only for a lower headline rate.
How Can Planning Help You Compare Prices?
A defined layout and furniture list give vendors clearer requirements to price.
Houspire’s published service includes room visualisation, Budget Direction and Vendor Direction. Additional drawings are separately priced, while construction, installation and on-site supervision are excluded. Use planning to decide what you need, then obtain execution quotations based on verified dimensions and specifications. A visualisation alone does not establish quantities or a fixed construction price.

Final Thoughts
Per sq ft pricing can be a useful reference when the measurement and scope are clear.
Before choosing a vendor, compare the actual work, specifications, exclusions and final payable amount. Keep the itemised quotation as your main reference throughout the project.

Frequently Asked Questions
Should interior pricing use carpet area or built-up area?
Ask which basis the provider uses and why. For comparison, both quotations must use an agreed, consistent area and equivalent scope.
Is a lump-sum quotation better than per sq ft pricing?
Either can work if the scope and specifications are detailed. A lump sum with vague inclusions can be just as difficult to assess.
Can I calculate a per sq ft rate from my total quotation?
Yes. Divide the total by the agreed apartment area. Label it as an effective project rate and retain the itemised breakdown.
Are labour and installation included in per sq ft rates?
Only if the quotation states that they are included. Confirm delivery, handling and installation separately.
What is the most useful question to ask a vendor?
Ask: “What is the final payable amount for this exact scope, and what will I still need to purchase or arrange separately?”
