Understanding the Concrete Calculation Formula
The calculator determines the amount of concrete needed by calculating volume first.
Concrete Volume Formula
Volume (ft3)=Length×Width×(12Thickness)
Since thickness is entered in inches, it must be converted into feet by dividing by 12.
Convert Cubic Feet to Cubic Yards
Concrete is usually sold in cubic yards.
Volume (yd3)=27Volume (ft3)
There are 27 cubic feet in 1 cubic yard.
Material Cost Formula
Material Cost=Concrete Volume×Price Per Cubic Yard
Total Concrete Pad Price Formula
Total Price=Material Cost+Labor Cost
Example Concrete Pad Calculation
Let’s calculate the cost of a concrete pad using real numbers.
Project Details
| Input | Value |
|---|---|
| Length | 20 feet |
| Width | 15 feet |
| Thickness | 4 inches |
| Concrete Price | $150 per yd³ |
| Labor Cost | $500 |
Step 1: Calculate Volume in Cubic Feet
Thickness in feet:
4 ÷ 12 = 0.333 feet
Now multiply:
20 × 15 × 0.333 = 99.9 cubic feet
Step 2: Convert to Cubic Yards
99.9 ÷ 27 = 3.70 cubic yards
Step 3: Calculate Material Cost
3.70 × $150 = $555
Step 4: Add Labor Cost
$555 + $500 = $1,055
Final Estimated Price
| Result | Amount |
|---|---|
| Concrete Volume | 3.70 yd³ |
| Material Cost | $555 |
| Labor Cost | $500 |
| Total Price | $1,055 |
