Result is shown in cubic meters (m³) and cubic feet (ft³).
Aggregate Quantity Calculator
Use this calculator to estimate coarse aggregate required for concrete. Enter volume in cubic meters and select mix grade.
How this works
Aggregate is calculated using:
Dry Volume = Wet Volume × 1.54
Aggregate = (Aggregate Ratio / Total Ratio) × Dry Volume
Result is shown in cubic meters (m³) and cubic feet (ft³).
Water Requirement Calculator (W/C Ratio)
Calculate water required for concrete using cement quantity and W/C ratio.
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.
How this works
Volume = Height × Width × Depth
Steel ≈ 120 kg per m³
Total Cost = Concrete Cost + Steel Cost
RCC Slab Cost Calculator
Estimate the cost of RCC slab including concrete and steel. Enter dimensions in meters.
How this works
Volume = Length × Width × Thickness
Steel ≈ 80 kg per m³ (slab)
Total Cost = Concrete Cost + Steel Cost

Retaining Wall Concrete Calculator PRO
Estimate concrete, cement, sand, aggregate, steel and retaining wall construction cost.
Wall Dimensions
Footing Dimensions
Material Rates
Engineering Formula
Wall Volume = Length × Height × Thickness
Footing Volume = Length × Footing Width × Footing Thickness
Total Concrete = Wall + Footing
Ready Mix Concrete Cost Calculator PRO
Calculate Ready Mix Concrete quantity, transit mixer trips, pumping cost and total project cost.
Concrete Dimensions
Concrete Details
Engineering Formula
Concrete Volume = Length × Width × Thickness
Total Cost = Concrete Cost + Pumping Cost
5% extra concrete added for wastage and uneven surface.
Concrete Weight Calculator PRO
Calculate concrete weight, density, dead load and truck load estimation.
Concrete Dimensions
Engineering Formula
Concrete Volume = Length × Width × Thickness
Concrete Weight = Volume × Density
Typical RCC concrete density = 2400 kg/m³

The foundation is the most important part of any building. It carries the entire load of the structure and transfers it safely to the ground. A strong foundation starts with proper footing design and accurate material calculation.
Many people ask:
👉 How much concrete is required for footing?
👉 How to calculate footing volume?
This is where a concrete footing calculator becomes very useful.
A concrete footing calculator helps you calculate the exact volume of concrete required for footings. It saves time, improves accuracy, and helps in proper planning.
In this article, you will learn everything about the concrete footing calculator, including formulas, examples, and practical construction tips.

📌 What is Concrete Footing?
A concrete footing is the lowest part of a foundation that:
- Supports columns or walls
- Distributes load evenly to soil
- Prevents settlement
Footings are generally wider than columns to spread the load.
🧮 What is a Concrete Footing Calculator?
A concrete footing calculator is a tool used to calculate the volume of concrete required for footing construction.
It takes input such as:
- Length
- Width
- Depth (thickness)
And provides output:
- Concrete volume in cubic meter (m³)
- Optional material estimation
This tool is widely used by:
- Civil engineers
- Contractors
- Builders
- House owners
📊 Types of Footings
Before using a concrete footing calculator, you should know the types:
🔹 1. Isolated Footing
Used for single columns
🔹 2. Combined Footing
Supports two columns
🔹 3. Strip Footing
Used under walls
🔹 4. Raft Footing
Covers entire building area
🧮 Formula Used in Concrete Footing Calculator
Step 1: Volume Calculation
👉 Volume = Length × Width × Depth
Step 2: Total Volume (Multiple Footings)
👉 Total Volume = Volume × Number of Footings
🧱 Example Calculation
Let’s understand with a practical example.
Given:
- Length = 2 m
- Width = 2 m
- Depth = 0.5 m
- Number of footings = 4
Step 1: Volume of One Footing
👉 2 × 2 × 0.5 = 2 m³
Step 2: Total Volume
👉 2 × 4 = 8 m³
👉 So, total concrete required = 8 cubic meters
🏠 Practical Use in Construction
In real projects:
- Small houses → isolated footing
- Medium buildings → combined footing
- Large structures → raft footing
Using a concrete footing calculator, you can estimate materials before starting excavation.
