Roof Calculator

Reinforced cement concrete (RCC) is the skeleton of every Pakistani building, and its cost depends on the concrete volume and the steel reinforcement ratio. This Roof Calculator estimates the concrete, steel and total cost for slabs, beams, columns and foundations.

The calculation uses the volume of the structural member and standard steel ratios — typically 1–1.5% of concrete volume for slabs and 2–3% for columns and beams — to arrive at the tonnage of steel and bags of cement required.

Steel is quoted per ton in Pakistan and its price swings with the international market, while cement is per bag. This tool converts the structural quantities into both, letting you price the RCC portion of your build accurately.

Structural design should always be checked by a qualified engineer — this calculator gives you the budgeting numbers, not the design. Use it to sanity-check contractor estimates and quantity lists.
