Cost of Concrete per Square Foot

Concrete Cost Formula:

\[ C = \frac{A \times D \times P}{27} \]

Total Cost:

1. What is Cost of Concrete per Square Foot?

Definition: This calculator estimates the total cost of concrete needed for a project based on area, depth, and price per cubic yard.

Purpose: It helps construction professionals and homeowners budget for concrete projects by calculating material costs.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ C = \frac{A \times D \times P}{27} \]

Where:

$ C $ — Total cost ($)
$ A $ — Area (square feet)
$ D $ — Depth (feet)
$ P $ — Price per cubic yard ($)
27 — Conversion factor (cubic feet per cubic yard)

Explanation: The area multiplied by depth gives cubic feet, which is converted to cubic yards (by dividing by 27) and then multiplied by price.

3. Importance of Concrete Cost Calculation

Details: Accurate cost estimation helps with project budgeting, material ordering, and avoiding unexpected expenses.

4. Using the Calculator

Tips: Enter the area in square feet, depth in feet, and price per cubic yard. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 27 in the formula?
A: There are 27 cubic feet in 1 cubic yard, so we convert from cubic feet to cubic yards for standard concrete measurements.

Q2: What's a typical concrete price per cubic yard?
A: Prices vary by region but typically range from $100 to $150 per cubic yard for ready-mix concrete.

Q3: Does this include labor or delivery costs?
A: No, this calculates material costs only. Additional costs for labor, delivery, or special mixes should be added separately.

Q4: How do I determine the right depth?
A: Depth depends on project type: 4 inches (0.33 ft) for sidewalks, 6 inches (0.5 ft) for driveways, 8-12 inches for foundations.

Q5: Does this include waste or overage?
A: No, consider adding 5-10% to the calculated cost for project contingencies and spillage.
