Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Bricks = net wall area × bricks per area. Mortar = bricks ÷ 1,000 × mortar factor × waste factor. Bags are rounded up.
FAQ
Brick Mortar Cost Calculator questions
Why estimate mortar from brick count?+
Brick count provides a practical link between wall area and the published mortar factor for a masonry unit and joint profile.
Should small openings be deducted?+
Large openings should be deducted. Small interruptions can be offset by cuts and waste.
Does mortar type change yield?+
Yes. Bag weight, mix design, water content and joint geometry affect actual yield.
