Staircase Concrete Calculator PRO

Calculate staircase concrete volume, cement, sand, aggregate, water, steel and total construction cost.

Number of Steps Tread / Step Length (m) Rise / Step Height (m) Width of Staircase (m) Waist Slab Thickness (m)

Material Rates

Cement Rate (₹ per bag) Sand Rate (₹ per m³) Aggregate Rate (₹ per m³) Steel Rate (₹ per kg)

Formula Used

Stair Length = √[(Total Rise²) + (Total Tread²)]
Concrete Volume = Length × Width × Thickness
Dry Volume = Wet Volume × 1.54

Retaining Wall Concrete Calculator PRO

Estimate concrete, cement, sand, aggregate, steel and retaining wall construction cost.

Wall Dimensions

Wall Length (m) Wall Height (m) Wall Thickness (m)

Footing Dimensions

Footing Width (m) Footing Thickness (m)

Material Rates

Cement Rate (₹ per bag) Sand Rate (₹ per m³) Aggregate Rate (₹ per m³) Steel Rate (₹ per kg)

Engineering Formula

Wall Volume = Length × Height × Thickness
Footing Volume = Length × Footing Width × Footing Thickness
Total Concrete = Wall + Footing

2. Detailed Cost Breakdown

A. Foundation and Plinth

1. Excavation (Digging the ground)
First, workers dig the soil where the house will stand. This creates space for the foundation. The depth depends on soil and design.

2. PCC (Plain Cement Concrete)
After digging, a thin layer of simple concrete is laid at the bottom. This is called PCC.

It acts like a clean and level base so the main foundation stays strong and doesn’t mix with soil.

3. RCC (Reinforced Cement Concrete)

Concrete Slab Cost Calculator

RCC Slab Cost Calculator

Estimate the cost of RCC slab including concrete and steel. Enter dimensions in meters.

Slab Length (m) Slab Width (m) Slab Thickness (m) Concrete Rate (₹ per m³) Steel Rate (₹ per kg)

How this works

Volume = Length × Width × Thickness
Steel ≈ 80 kg per m³ (slab)
Total Cost = Concrete Cost + Steel Cost

Now the main strength part comes. Steel bars are placed and strong concrete is poured.

This forms the foundation and plinth beam, which holds the entire weight of the house.

4. Plinth Beam

Foundation Plinth

This is a horizontal beam just above the ground level.

It connects all columns and walls, and protects the house from cracks and moisture.

5. Backfilling
After everything is done, the empty spaces around the foundation are filled again with soil.

This helps in supporting the structure and making the ground level even.

Description: Includes excavation, PCC, and RCC work for the foundation, plinth beam, and backfilling.

- Rate: ₹350/sqft

- Cost: 2550 sqft × ₹350 = ₹8,92,500

Factors Influencing Cost:

1. Soil condition: Loose soil requires deeper foundations.

1. Type of foundation: RCC footing, isolated footing, or pile foundation.

Superstructure (Walls and Slabs)

This is the main visible part of your house—everything you see above the ground level.

After the foundation is ready, this stage builds the actual shape of your home.

Here’s what it includes in simple words:

1. Columns (Vertical supports)
These are strong concrete pillars made with steel and cement.
They carry the weight of the whole building and transfer it safely to the foundation.

2. Beams (Horizontal supports)

Beams connect the columns from one side to another.
They hold the structure together and support the roof and slabs.

3. Brickwork (Walls)
Bricks are arranged with cement to form walls.
These walls divide rooms and give shape to your house.

Water Requirement Calculator (W/C Ratio)

Calculate water required for concrete using cement quantity and W/C ratio.

Cement Quantity (bags) Water-Cement Ratio Select Concrete Type (Optional)

Formula Used

Water = Cement Weight × W/C Ratio

1 bag cement = 50 kg
1 kg water = 1 litre

Pro Tip (Very Important)

The water-cement ratio directly affects concrete strength and durability.

PCC: 0.6 – 0.7
RCC: 0.4 – 0.5
High Strength: 0.3 – 0.4

RCC Column Cost Calculator

Estimate the cost of RCC column including concrete and steel. Enter dimensions in meters.

Column Height (m) Column Width (m) Column Depth (m) Concrete Rate (₹ per m³) Steel Rate (₹ per kg)

How this works

Volume = Height × Width × Depth
Steel ≈ 120 kg per m³
Total Cost = Concrete Cost + Steel Cost

4. Slab (Roof/Floor concrete)

This is the flat concrete surface (roof or floor).
It is where you walk, place furniture, and live your daily life.

This one is a standard estimate. Detailed specific estimate will be calculated after drawing is confirmed. Every house is different based on the plot and clients demand. For example –
Example – 01

Depending on the soil test the type of footing will be determined. Also Piling is needed or not will be confirmed after the soil test report is ready. It will impact the costing.

Example – 02

Depending on the site location, and Client requirement the plinth height will vary from minimum 2.5 Ft to 5 Ft max. This will impact on the costing. The variation on Plinth height will vary in costing due to variation in plinth brickwork and sand filling.

Example – 03

The number of rooms, bathroom, kitchen in a floor will determine its exact costing. Less the entity less is the costing.

So, these are some of the entity which impact on the cost variation in the of estimate of g+1 building.
