Plan brick quantities, cuts, and costs with confidence. Model openings, waste, wall thickness, and packing. Download shareable reports for faster approvals and smoother coordination.
Sample scenario to illustrate typical outputs.
| Wall (m) | Openings (m2) | Brick (mm) | Joint (mm) | Waste (%) | Cut (%) | Cut Loss (%) | Required Bricks | Purchase Qty |
|---|---|---|---|---|---|---|---|---|
| 8.0 x 3.0 | 1.8 | 230x110x70 | 10 | 5 | 7 | 15 | ~1,260 | 1,500 (3 packs of 500) |
Tip: Use your supplier’s pack size to reduce overage.
The calculator estimates wall net area, converts brick dimensions to a modular face size, then applies allowance factors.

A practical approach to forecasting brick quantities with cutting allowances.
Brickwork rarely consumes only full units. Returns at corners, jambs, reveals, copings, and closures create partial bricks. A dedicated allowance protects the schedule by preventing mid‑lift shortages and avoids overbuying that ties up cash and storage space.
Start with gross wall length and height, then subtract openings as a single summed area. Confirm the brick’s nominal length and height, and the typical mortar joint used by your crew. These values define the modular face size and strongly influence bricks per square meter.
Wall thickness changes quantities by wythe count. A half‑brick leaf is a single wythe; a one‑brick wall is typically two wythes. Bonding and detailing can shift consumption, so the adjustment factor lets you align the estimate with your preferred bond pattern and local practice.
Not every brick is cut. The cut ratio represents the share impacted by edges, openings, and terminations. The corner and complexity factor increases this share for heavy detailing, frequent returns, or irregular geometry, where small pieces often become unusable.
General waste covers handling breakage, chip damage, and site losses. Cutting loss is different: it applies only to the cut portion and reflects offcuts that cannot be reused, saw‑kerf losses, and rejected pieces. Keeping both allowances separate gives cleaner control.
Suppliers deliver in packs, so the purchase quantity should round up to a full pack count. The calculator reports required bricks, packs needed, purchase quantity, and overage. This helps you compare suppliers and choose a pack size that reduces leftover stock.
Example: wall 8.0 m by 3.0 m with 1.8 m2 of openings, brick 230x110x70 mm, 10 mm joints, 5% general waste, 7% cut ratio, and 15% cutting loss. With 500‑brick packs, the estimate rounds to three packs, ensuring continuity during laying.
Before final procurement, confirm whether the wall includes piers, soldier courses, arches, or special units. Validate that openings area includes lintel pockets and service chases if applicable. Once site conditions are known, re‑run the calculator and export the report for approvals.
Use the exported report to align procurement, supervision, and billing records. Document revisions, supplier lead times, and handling rules to keep assumptions consistent.
An added quantity that covers losses from cutting bricks at corners, openings, and terminations. It focuses on unusable offcuts and rejected pieces, separate from general site waste.
Use past projects or count edge conditions on drawings. Simple straight walls may use 3–6%, while walls with many openings, returns, and details can reach 8–15%. Adjust the complexity factor if the geometry is irregular.
Joint thickness changes the modular face size. A larger joint increases the module area, reducing bricks per square meter, while a smaller joint increases brick count. Match the joint your crew typically achieves.
Yes. Select the thickness mode to apply a wythe multiplier. Use half‑brick for a single leaf, one‑brick for two leaves, and higher modes for thicker masonry. Confirm structural drawings before ordering.
Set waste based on handling and storage conditions. Protected storage and careful handling may need 3–5%, while tight access, rehandling, or long hauling can justify 6–10%. Keep waste separate from cutting loss.
Suppliers sell bricks in fixed pack sizes. Rounding prevents partial-pack ordering problems and reduces delivery delays. The reported overage helps you plan storage, returns, or reuse on adjacent work.
Yes, as a quick estimate. Enter unit cost per brick and an optional cost per cut brick. The total combines material and cutting estimates. Validate with supplier quotes and site productivity data before committing.
