House Construction Cost Calculator
Estimate the total cost of building a house from the built-up area, number of floors and the construction rate in your city.
Inputs
Typical civil + finishing rate in your area
Formula
- Total area = area per floor × number of floors
- Cost = total area × rate × quality factor
- Grand total = cost + extra works
Builders quote houses per square foot of built-up area. Multiply that rate by the total area of all floors and you have the civil + finishing cost. Quality changes the rate: budget finishes cost roughly 15% less than standard, premium fittings roughly 30% more. The split shown below (structure, finishing, MEP) is the typical share for a residential build so you can plan payments stage by stage.
Step-by-step calculation
- 1
Total area
area × floors
1,200 sq ft
- 2
Adjusted rate
rate × quality factor
₹1,800/sq ft
- 3
Construction cost
area × rate
₹21,60,000
- 4
Grand total
cost + extra works
₹21,60,000
Worked example
- 11,200 sq ft ground + first floor = 2,400 sq ft.
- 2Standard quality at ₹1,800/sq ft → 2,400 × 1,800 = ₹43,20,000.
- 3Add ₹2,00,000 for the compound wall → ₹45,20,000.
Tips
- Ask two local contractors for their current per-sq-ft rate — it changes with steel and cement prices.
- Keep 10% of the budget aside as contingency; almost every project needs it.
Frequently asked questions
Does this include land cost?
No. It covers construction only — structure, finishing and basic services. Land, registration and approvals are separate.
What rate should I enter?
Use the all-in rate your local contractor quotes for a turnkey civil job. In most Indian cities it ranges from ₹1,500 to ₹2,500 per sq ft.
Why is the cost split into stages?
So you can plan cash flow — the structure is paid during the first months, finishing and services near the end.
