Masonry Calculator
Calculate the number of CMU blocks or bricks for a wall, with mortar, grout and an installed cost.
How the masonry calculator works
Enter the gross wall area and deduct openings. The calculator uses the number of units per square foot for the unit you choose, with 5% waste.
Mortar is calculated from typical usage per square foot of wall and converted to 80 lb bags. For CMU walls, grout is calculated from the cell spacing you choose, from partially grouted to solid.
Material and labor costs use the unit price and installed labor rate you enter.
