Save the current estimate as A, change something (quality, floors, finishes), then save it as B.
How the estimate is calculated
Every number the calculator uses is listed here, so you can see exactly which assumption differs from a contractor's quote.
Built-up area = room areas × 1.10 (Quick mode: entered directly)
Core materials = area × quantity rule × rate × quality × structure × material location
Finishing = area-based finishes + bathroom sets + kitchen platform + add-ons
Labour = (45% of core + 35% of finishing, at Urban rates) × labour location
Total = (core + finishing + labour) × 1.10, shown with a ±10% range
Days = area × 0.15 × (1 + 0.10 per extra floor) × quality factor

What the estimate covers
Use it to set a budget and to check quotes. The items on the right need a separate line in your budget.
Included
- Structure: cement, steel, bricks, sand and aggregate from per-sq.ft. quantity rules.
- Finishes: flooring, doors, windows, electrical points, painting, plumbing, sanitaryware sets, kitchen platform.
- Labour: linked to material value and adjusted for location.
- Add-ons: false ceiling and modular kitchen when switched on.
- 10% allowance for transport, wastage and minor site items.
Not included
- Land and registration.
- Approvals: plan sanction, development and connection charges.
- Professional fees: architect, structural engineer, supervision.
- GST as a separate line.
- Site work: compound wall, borewell, septic tank, poor soil, slopes, demolition.
After you have a number
Three steps that make the estimate useful when you talk to contractors.
Budget at the top of the range
Plan money around the upper figure and keep land, approvals and GST as separate lines.
Send the same scope to three contractors
Share your PDF so every quote covers the same rooms, floors and finish levels.
Compare line by line
Convert each quote to built-up area. Check cement and steel brands, exclusions, the stage-linked payment plan and the completion date.
Questions
How should I read the estimate?
The calculator gives a preliminary estimate from your inputs and its configured rates, shown as a central figure with a ±10% range. Local material prices, labour rates, brands, taxes and site conditions can move the real cost. Use it to set a budget and to check contractor quotations, not as a quotation.
Is the area carpet area or built-up area?
In Detailed mode you enter internal room sizes, and the calculator adds a 10% wall allowance to estimate built-up area. In Quick mode you enter built-up area per floor directly. All per-sq.ft. rules, the cost per sq.ft. and the timeline use built-up area. Garden is excluded; covered parking is included.
What is included in the estimate?
Core structural materials, finishing materials (flooring, doors, windows, electrical points, painting, plumbing, sanitaryware sets and kitchen platform), labour, optional false ceiling and modular kitchen, and a 10% other-cost allowance. Land, approval charges, professional fees, GST as a separate line, compound wall, borewell, septic tank and unusual site conditions are not included.
Does the estimate include GST?
GST is not calculated as a separate line. The rates are planning rates and the 10% allowance is not a tax calculation. Ask each contractor whether their quote includes GST and compare on the same basis.
Why is a contractor's per-sq.ft. rate different?
Contractors may quote on carpet, built-up or super built-up area, and may include or exclude sanitaryware, electrical fittings, GST or the compound wall. Convert every quote to built-up area and the same list of included items before comparing.
Which multipliers does the calculator use?
Quality: Basic 0.80, Standard 1.00, Premium 1.30. Material location: Rural 0.90, Semi-Urban 0.96, Urban 1.00, Metro 1.10. Labour location: 0.85, 0.95, 1.00, 1.15. Structure on core materials: RCC frame 1.00, load bearing 0.95. Labour is 45% of core and 35% of finishing material value before the labour location factor. The full table is on this page.
Can I compare two options?
Yes. Save the current inputs as Scenario A, change anything, save as Scenario B, then open the Compare tab to see both side by side with the difference. Both scenarios also appear as markers on the cost-per-sq.ft. scale.
Can I save or share the estimate?
Save as PDF opens your browser's print dialog with a clean one-document report. Copy link creates a URL that reopens the calculator with your inputs. WhatsApp shares a short summary with the total, range, area, cost per sq.ft. and timeline.
Is the calculator free?
Yes. It is free and needs no account or sign-up.
Is my project data sent anywhere?
No. The calculation runs in your browser and the tool loads no third-party scripts. The only external request is for the web font from Google Fonts. Your inputs leave the page only if you copy a link or share on WhatsApp yourself.
