Calculators
Working calculators for quick planning.
Enter the measurements you have, keep units consistent, and use the formula notes to understand how each result is estimated.
Concrete & Masonry
Concrete Volume Calculator
Calculate concrete volume for a rectangular slab or pad.
Results
Enter the required measurements to calculate results.
Cubic yards = length x width x depth(in) / 12 / 27. Waste is applied after measured volume.
Help
- Subgrade variation, thickened edges, and over-excavation are not included unless entered in dimensions/waste.
Concrete & Masonry
Footing Volume Calculator
Calculate continuous footing concrete volume.
Results
Enter the required measurements to calculate results.
Cubic yards = length(ft) x width(in)/12 x depth(in)/12 / 27. Waste is applied after measured volume.
Help
- Does not include piers, haunches, grade changes, or overdig unless included by the user.
Concrete & Masonry
Bag Quantity Calculator
Estimate concrete bags from required volume and bag size.
Results
Enter the required measurements to calculate results.
Bags = required cubic feet x (1 + waste) / bag yield.
Help
- Bag yields are approximate; check the product label for exact yield.
Concrete & Masonry
Block Count Calculator
Estimate CMU block count from wall area, block face size, and waste.
Results
Enter the required measurements to calculate results.
Blocks = wall area x (1 + waste) / block face area.
Help
- Openings, bond beams, corners, cuts, and special units should be handled separately.
Concrete & Masonry
Mortar Estimate
Estimate mortar bags for CMU block work.
Results
Enter the required measurements to calculate results.
Mortar bags = block count x (1 + waste) / blocks per bag.
Help
- Coverage varies with block size, joint thickness, waste, and mason technique.

Before You Calculate
Start with clear measurements.
Measure length, width, depth, height, or diameter as applicable.
Separate slabs, footings, and vertical work into clear sections.
Confirm site prep, reinforcement, and structural details before work proceeds.
