How to Use the Concrete Patio Calculator
Using this tool is very easy. Just follow these steps:
Step 1: Enter Length
Input the length of your patio or slab in feet.
Step 2: Enter Width
Enter the width of the area in feet.
Step 3: Enter Depth
Provide the depth (thickness) in inches. This is important for accurate volume calculation.
Step 4: Enter Cost per Cubic Yard
Input the price of concrete per cubic yard. If you don’t know, you can check local supplier rates.
Step 5: Click Calculate
Press the Calculate button to instantly see:
- Total concrete volume (cubic yards)
- Estimated total cost
Step 6: Reset (Optional)
Click the reset button if you want to perform another calculation.
Example Calculation
Let’s understand with a real-life example:
- Length: 20 feet
- Width: 10 feet
- Depth: 4 inches
- Cost per cubic yard: $120
Step-by-step Calculation:
- Convert depth into feet:
4 inches ÷ 12 = 0.33 feet - Calculate cubic feet:
20 × 10 × 0.33 = 66 cubic feet - Convert to cubic yards:
66 ÷ 27 = 2.44 cubic yards - Calculate total cost:
2.44 × 120 = $292.80
👉 Final Result:
- Volume = 2.44 cubic yards
- Total Cost = $292.80
