Construction calculators that give you quantities, not guesses
Brick, tile, paint, concrete, cost and plot-area calculators built on standard Indian practice — with wastage, joint sizes, mix ratios and rates shown instead of hidden.

Open calculatorWhat this vertical covers
A construction estimate is only useful if it matches how material is actually bought — bags of cement, boxes of tiles, litres of paint, thousands of bricks. These calculators turn a drawing dimension into the quantity on the order.
They use standard Indian practice: 190 × 90 × 90 mm modular bricks with 10 mm joints, 50 kg cement bags, a dry-volume factor of 1.54 for concrete, 1 gaj = 9 sq ft for plots. Each page explains the factor it uses and lets you change the wastage or rate.
The cost calculator is different from the others on purpose: it is only as good as the rate you put in. It starts from a dated planning figure and asks you to replace it with your contractor's quote or the CPWD plinth-area rate for your city.
Worth knowing before you calculate
5–10% is normal, not an error
Breakage and cutting mean you buy more than the geometric area. Every calculator exposes wastage as an input instead of quietly adding a percentage.
Material rates move; quantities do not
The quantity calculators are independent of price. The construction cost calculator takes a rate you can edit for your city and month, and states what it excludes.
Feet, metres and gaj all appear on site
Indian drawings mix units. The plot area converter covers gaj, square feet, square metres, acre and hectare, and the other calculators state the unit they expect.
The two inputs that move the most money
Wall thickness doubles the brick count; the concrete mix ratio changes cement by bags. Both are selectable on their pages, with the standard values labelled.
