Land, planning, quantity and cost calculators for Indian development

Indian land is quoted in a different unit every 200 kilometres. Convert one measurement into every unit at once, with the exact factor applied shown next to each result.

Enter measured boundary lengths and get the plot area. For irregular sites the calculation splits the plot into two triangles across a measured diagonal, which is the method a site survey actually uses.

Convert an asking price into every rate basis at once, so you can compare a per-cent quote in one town against a per-square-foot quote in the next.

The price is not the cost. Add the statutory and transaction charges you will actually pay and see the effective rate per square foot that belongs in your appraisal.

Enter the plot, the area you will surrender, and the base and premium FSI your authority permits. Get the built-up area the site can legally carry, split by entitlement.

Work forwards from a permitted coverage percentage to the footprint you may build, or backwards from a measured footprint to the coverage you are consuming.

Enter whichever area you actually know and get the other two, with the loading between carpet and the quoted super built-up figure made explicit.

Take a total built area down to what you can actually sell after services, circulation and amenity, then back up to the super built-up figure you would quote.

Enter member dimensions and counts to get net concrete volume, the wastage allowance you choose, and the volume to order.

Convert a concrete volume into cement bags, sand and coarse aggregate using your own nominal mix ratio and dry-volume factor.

Enter wall dimensions, brick size and mortar joint to get the brick count including wastage, plus the mortar cement and sand it consumes.

The same wall arithmetic for AAC or solid concrete blocks, where the larger unit size and thinner joint change both the count and the mortar consumed.

Convert bar diameter, length and count into kilograms and tonnes using the d²/162 unit-weight rule, with a wastage and lap allowance you set.

Concrete volume for a floor slab from length, breadth and thickness, plus indicative reinforcement weight at the steel intensity you specify.

Concrete volume for beams from span, width and depth, multiplied across the number of identical beams, with an indicative reinforcement weight.

Concrete volume for columns from section size and height, across the number of columns, with an indicative reinforcement weight.

Concrete volume for isolated pad footings from plan size and depth, across the number of footings, with an indicative reinforcement weight.

Enter the area to be plastered, the thickness in millimetres and your mortar ratio to get cement bags and sand.

Convert a floor area and a tile size into the number of tiles, the boxes to order and the purchase area, with the grout joint accounted for.

Turn a built-up area and the rate you have been quoted into a full development construction budget, with professional fees, statutory charges, external works, escalation and contingency shown as separate, editable lines.
