RCC Slab Cost Per Square Feet in India (2026 Rates)
The slab is one of the most expensive single elements of any house, so pricing it accurately protects your margin. Here's a clean 2026 breakdown for India.
Typical all-in cost
A standard residential RCC slab (M20, 125–150 mm) costs about ₹180–₹250 per sq ft including material and labour. For a 1000 sq ft slab that's roughly ₹1.8–2.5 lakh.
Cost components
| Component | Approx. share |
|---|---|
| Cement | 20% |
| Steel (TMT) | 30% |
| Sand + aggregate | 18% |
| Shuttering / centering | 15% |
| Labour | 17% |
Steel is the swing factor — when TMT rates move ₹5/kg, a 1000 sq ft slab shifts by thousands of rupees.
What changes the price
- Thickness — 150 mm costs more than 125 mm.
- Steel rate — track the day's TMT rate before quoting.
- Span & load — longer spans need more steel.
- City — metro labour and material rates run higher.
Quote it, don't guess it
The contractors who protect margin are the ones who quote from a live rate sheet, not last month's memory. Vystra's quotation builder lets you build a GST-ready RCC slab estimate in minutes and lock the rates you actually bought at — so the quote and the P/L match.
