Sakrete Concrete Calculator — Calculate Concrete Requirements

Sakrete Concrete Calculator

Calculate how much Sakrete concrete mix you need for your project. Determine bags needed, total cost, and coverage based on project dimensions and depth.

Step 1: Project Dimensions

10 ft
8 ft
4 in

Standard Concrete Depth

Most concrete projects require 4 inches of thickness for adequate strength. Driveways and areas with heavy loads may need 6 inches. Always check local building codes.

Step 2: Concrete & Cost

Sakrete Coverage Information

One 60 lb bag of Sakrete yields approximately 0.45 cubic feet of concrete. Add 10-15% extra for waste, spillage, and uneven subgrades.

Concrete Calculation Formula

Volume (cubic yards) = (Length × Width × Depth) ÷ 324

To calculate concrete volume: Multiply length (ft) × width (ft) × depth (inches) ÷ 12 to get cubic feet, then divide by 27 to get cubic yards. Add waste factor (typically 10%).
