About the Construction Cost Calculator
What is the Construction Cost Calculator?
Building a house is usually priced per square foot of built-up area. This construction cost calculator multiplies your area by the rate for the quality you want, adds a contingency buffer and the cost of approvals and utility connections.
It also splits the cost into materials, labour and finishing, and estimates quantities of cement, steel, sand, aggregate and bricks using common thumb rules.
How to use the Construction Cost Calculator
- Built-up Area to Construct (sq ft) (sample: 2,000)
- Construction Rate (₹ per sq ft) (sample: 2,200)
- Contingency (% of cost) (sample: 10)
- Approvals, Design & Utility Connections (₹) (sample: 2,50,000)
- Press Estimate Construction Cost (results also refresh as you type). The result card shows the Estimated Construction Cost, along with Materials (about 60%), Labour (about 25%), Finishing, fittings & other (about 15%) and Cost per sq ft incl. extras.
Formula used
Total cost = Area × Rate × (1 + Contingency %) + Approvals
- Rate = basic ₹1,800–2,000, standard ₹2,000–2,600, premium ₹2,800+ per sq ft
- Materials = cement 0.4 bag, steel 4 kg, sand 1.8 cu ft, aggregate 1.35 cu ft, bricks 8 per sq ft
Thumb-rule quantities are for early budgeting; a structural engineer's estimate is needed for buying materials.
Worked example
These are the sample values already filled in the calculator above, and the result it returns for them:
| Input | Sample value |
|---|---|
| Built-up Area to Construct (sq ft) | 2,000 |
| Construction Rate (₹ per sq ft) | 2,200 |
| Contingency (% of cost) | 10 |
| Approvals, Design & Utility Connections (₹) | 2,50,000 |
| Result | Value |
|---|---|
| Estimated Construction Cost | ₹50,90,000 |
| Materials (about 60%) | ₹26,40,000 |
| Labour (about 25%) | ₹11,00,000 |
| Finishing, fittings & other (about 15%) | ₹6,60,000 |
| Cost per sq ft incl. extras | ₹2,545 |
Tips for using the Construction Cost Calculator
- Keep a 10–15% contingency; material prices and design changes add up.
- Land cost is separate; this estimate covers construction only.
- Agree on a detailed item-rate or turnkey contract to avoid disputes.
