Cement Calculator
Estimate Portland cement bags, sand, gravel, water and cost for concrete, mortar, screed or masonry mixes.
Estimates use common dry-material weights per cubic yard and convert area jobs from square feet and inch thickness. Bag products, aggregate moisture and specified mix designs can change the final order quantity.
Estimate cement bags for a mix
English cement-calculator searches usually ask how many bags of cement are needed for a concrete, mortar or screed quantity. This page should show bags, dry materials, water and cost in U.S.-friendly units.
Use the result as a planning takeoff
- Ready-mix concrete, bagged concrete and site-batched cement mixes are not interchangeable.
- Water-cement ratio, aggregate moisture, admixtures and strength requirements can change the recipe.
- For structural concrete, follow the project specification, supplier design and local code.
