Construction & Building Calculators

Concrete, flooring, roofing, framing, masonry, and materials estimates.

The construction calculators estimate quantities of materials such as bricks, concrete, tiles, paint and steel, plus cost totals for small projects. Most work from areas and volumes, then add an allowance for wastage.

Quantities depend on the actual products you buy, such as brick size, bag weight and tile dimensions, and on site conditions. Treat the results as a starting estimate for ordering and budgeting, and confirm them with your supplier or contractor.
