Concrete Driveway Calculator

💡 How to Calculate Concrete for a Driveway

Driveway concrete volume = length × width × thickness. Standard residential driveway thickness is 4–5 inches for passenger cars and 5–6 inches for heavy vehicles. Always order 10% extra for waste, subgrade variations, and over-excavation.

A two-car driveway is typically 20–24 feet wide. Single-car driveways are 10–12 feet wide. Include aprons, turnarounds, and walkways in your calculations. Ready-mix concrete costs $120–$160 per cubic yard delivered.
