Calculate concrete batch yield from total weight and fresh density, compare actual versus design volume, or derive unit weight from a calibrated measure.

Use measured fresh-concrete density and the actual total batch mass for yield. A volume comparison alone does not establish concrete quality, delivery compliance or the cause of a short pour.

For yield, enter all batched materials. For density, enter only the concrete in the known measure.

Concrete Yield Formula

The following formula is used to calculate concrete yield (the batch volume of concrete produced).

Y = W / D

Variables:

  • Y is the concrete yield (a volume, such as ft³, yd³, or m³)
  • W is the total weight of all materials in the batch (lb or kg)
  • D is the unit weight (density) of the fresh concrete (lb/ft³ or kg/m³)

To calculate the concrete yield, divide the total batch weight (W) by the unit weight (density) of the fresh concrete (D). This gives yield in volume units consistent with the density used (for example, lb divided by lb/ft³ gives ft³). Convert units as needed (1 yd³ = 27 ft³; 1 m³ ≈ 35.3147 ft³). Use actual total batch mass and measured fresh density, not hardened-concrete density. For density mode, divide net concrete mass, excluding its container, by a calibrated known volume. Relative yield is actual volume divided by design volume; the difference is actual minus design. An over-yield is not by itself a quality pass. See NRMCA CIP 8 for yield measurement and the distinction between yield discrepancies and site consumption.

What is a Concrete Yield?

Concrete yield is the volume of concrete produced by a batch. It is commonly calculated by dividing the total batch weight of all materials by the measured unit weight (density) of the fresh concrete. The yield is usually expressed in cubic yards, cubic feet, or cubic meters. It is an important measure as it helps in checking batching accuracy and estimating material usage and cost.

How to Calculate Concrete Yield?

The following steps outline how to calculate the Concrete Yield.

  1. Determine the total batch weight of all materials (W) in pounds or kilograms.
  2. Determine the measured unit weight (density) of the fresh concrete (D) in lb/ft³ or kg/m³.
  3. Use the formula Y = W / D to calculate the concrete yield (Y).
  4. Convert the result to your desired volume unit if needed (for example, ft³ to yd³ by dividing by 27).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total batch weight of all materials (W) = 40,500 pounds

unit weight (density) of fresh concrete (D) = 150 lb/ft³

concrete yield (Y) = W / D = 40,500 / 150 = 270 ft³ = 10 yd³
