How this is calculated

Formula

  1. Convert ft/in → m/mm if imperial is selected
  2. wall_volume = L × H × T
  3. brick_with_mortar = (l+j) × (w+j) × (h+j)
  4. bricks = ceil(wall_volume ÷ brick_with_mortar)
  5. mortar_wet = wall_volume − bricks × brick_solid_volume
  6. mortar_dry = mortar_wet × 1.33
  7. Split mortar by cement:sand ratio → bags & sand (cft)
  8. cost = bags × ₹/bag + sand_cft × ₹/cft

Assumptions

  • Choose Metric (m, mm) or Imperial (ft, in) for wall and brick sizes.
  • Default brick size is modular Indian 190 × 90 × 90 mm.
  • Brick count uses brick size plus mortar joint on each face.
  • Mortar wet volume = wall volume − (bricks × solid brick volume); dry × 1.33.
  • Openings (doors/windows) are not deducted — subtract their volume manually.
  • Add ~5% extra bricks for breakage on site.
  • Cost covers cement and sand only — bricks and labour are separate.
  • Cost = (cement bags × ₹/bag) + (sand cft × ₹/cft).
