How to Calculate Concrete
Concrete volume is calculated by multiplying length × width × thickness. The result in cubic feet is divided by 27 to get cubic yards — the standard unit for ordering ready-mix concrete in the US.
Always add a waste factor of 10% for standard pours. For complex shapes or first-time pours, use 15–20%.
Ready-mix vs. bags: For anything over 1 cubic yard, ready-mix is more economical than bagged concrete.
Ready-Mix Prices (2026)
Small orders (<5 CY) often carry a short-load fee of $50–$200.
