Concrete Calculation Formula Explained
The Concrete Network Calculator uses standard volume formulas used in construction.
Basic Concrete Volume Formula
The basic formula for rectangular concrete areas is:
Volume = Length × Width × Thickness
When measurements are entered in feet:
Cubic Feet = Length × Width × Depth
Example:
Length = 20 feet
Width = 10 feet
Thickness = 0.5 feet
Calculation:
20 × 10 × 0.5 = 100 cubic feet
The project requires 100 cubic feet of concrete.
Converting Cubic Feet to Cubic Yards
Concrete suppliers commonly sell concrete by cubic yards.
Since:
1 cubic yard = 27 cubic feet
The conversion formula is:
Cubic Yards = Cubic Feet ÷ 27
Example:
100 cubic feet ÷ 27 = 3.70 cubic yards
Therefore, approximately 3.70 cubic yards of concrete are required.
Extra Concrete Allowance Formula
Construction projects often require additional concrete because of:
- Uneven ground conditions
- Spillage
- Measurement differences
- Small adjustments
The calculator adds approximately 10% extra concrete.
Formula:
Extra Concrete = Required Cubic Yards × 10%
Example:
Required concrete = 3.70 cubic yards
Extra:
3.70 × 0.10 = 0.37 cubic yards
Total recommended concrete:
3.70 + 0.37 = 4.07 cubic yards
Concrete Bag Estimation Formula
For smaller projects, concrete bags may be more convenient.
The calculator estimates the number of 80-pound bags needed based on concrete volume.
Formula:
Concrete Bags = Cubic Feet ÷ 0.60
The result is rounded upward because buying fewer bags than required can interrupt your project.
Practical Example: Calculating Concrete for a Patio
Suppose you want to build a concrete patio with these measurements:
- Length: 20 feet
- Width: 12 feet
- Thickness: 4 inches
- Concrete price: $150 per cubic yard
First, convert thickness:
4 inches ÷ 12 = 0.33 feet
Calculate volume:
20 × 12 × 0.33 = 79.2 cubic feet
Convert to cubic yards:
79.2 ÷ 27 = 2.93 cubic yards
Add 10% extra:
2.93 × 0.10 = 0.29 cubic yards
Total recommended concrete:
2.93 + 0.29 = 3.22 cubic yards
Estimated material cost:
3.22 × $150 = $483
This calculation helps you understand approximately how much concrete to order and what your material expense may be.
