Construction Calculators

Estimate materials and costs for building projects - bricks, cement, concrete, steel, tiles, paint, sand, aggregate, plaster and excavation - with accurate, engineering-based formulas.

Brick Calculator

Estimate bricks and mortar for a Nepal/South-Asia wall from length, height, brick size, joints and wastage — not a mason’s final order.

Cement Calculator

Estimate cement bags from concrete or mortar volume and mix ratio (for example 1:2:4) with a wastage allowance.

Concrete Calculator

Estimate concrete volume for slabs, footings or walls from length, width and depth, plus a waste factor for site placement.

House Cost Calculator

Planning-level house cost from area and a construction rate — use Nepal House Cost when you want Nepal-labelled NPR assumptions.

Paint Calculator

Estimate paint litres from room dimensions, coats and coverage — with Nepal tin sizes (1, 4, 10, 20 L) in mind.

Plaster Calculator

Estimate plaster volume and cement/sand for wall or ceiling plaster thickness and mix ratio.

Rebar Calculator

Build a reinforcement quantity check from bar lists — companion to the steel weight tool for house and RCC work.

Sand Calculator

Estimate sand volume for concrete, mortar or plaster from the mix and the structural volume you already calculated.

Steel Weight Calculator

Estimate reinforcement steel weight from bar diameter, length and number of bars (unit weight tables).

Tile Calculator

Estimate tile pieces and boxes from floor/wall area, tile size and wastage for cuts and spares.
