Construction Calculators
Engineered for civil site supervisors, contractors, and home builders, our construction estimators apply Bureau of Indian Standards (IS 456, IS 1077, IS 2502) and CPWD DSR schedule rates for raw material budgeting.

Logical Groupings in Construction
Structural Concrete & Masonry
Calculate concrete mix batches, dry volume multipliers, and modular brick counts.
Finishing & Surface Architectural Estimation
Estimate floor tile coverage, mortar grout, and interior/exterior paint spreading.
How to Choose the Right Calculator
Identify your specific scenario to select the appropriate mathematical or statutory model:
Ordering cement, sand, and aggregates for a concrete slab
Converts wet volume to dry volume using the statutory 1.54 multiplier across M15/M20/M25 grades.
Use Concrete CalculatorEstimating wall bricks and masonry mortar bags
Applies the IS 2212 500-bricks/m³ standard with 5%–10% cutting wastage allowance.

Calculate rectangular or cylindrical water tank capacity in litres, cubic metres, and US gallons from internal dimensions.
AAC Block Calculator
Estimate AAC blocks, wall volume, wastage, adhesive bags, and material cost after deducting door and window openings.
Staircase Calculator
Calculate staircase steps, riser height, tread depth, total run, stair angle, and stringer length from your floor-to-floor height and available space.
House Construction Cost Calculator
Estimate house construction cost in India from built-up area, city tier, quality, and floors. Review per-square-foot rates plus material and labour shares.
Brick Calculator
Estimate bricks or blocks for a wall from its length, height, and thickness, including joint volume, wastage, unit price, and material cost.
Cement Calculator
Estimate 50 kg cement bags, cement weight, volume, and cost for slabs, foundations, beams, columns, and floors using project dimensions and concrete grade.
Concrete Calculator
Calculate concrete volume, cement bags, sand quantity, aggregate quantity, and material costs for slabs, foundations, columns, beams, and construction projects.
Tile Calculator
Find out exactly how many tiles, boxes, and how much grout and adhesive you need for any room. Enter your room dimensions, tile size, and a safety wastage margin — and get a clear breakdown of tiles required, boxes to buy, and estimated cost, so you don't run short mid-job or overspend on extras.
Rebar Cutting Length Calculator
Calculate the exact cutting length of reinforcement bars before fabrication. Enter the bar shape, span or member dimension, diameter, bend angles, hook type, and concrete cover — and get the cutting length, bend deductions, and steel weight, based on IS 2502 practice used across Indian construction sites.
Paint Calculator
Estimate exactly how much paint your walls, room, or entire house needs. Enter your area, number of coats, and paint type — and get litres required plus an approximate cost, so you buy the right quantity the first time.
Stamp Duty Calculator
Calculate stamp duty and registration charges for residential and commercial property purchases across Indian states. Compare state-wise rates, metro cess, and women buyer concessions instantly.
Frequently Asked Questions about Construction Tools
Why do construction estimators include wastage percentages?
Job-site transit breakage, corner cuts, overlap splices, and mortar absorption require a standard 5% to 15% safety buffer depending on the raw material.
