Why MistriCalc
Construction maths in Pakistan runs on units no global calculator understands — a plot is sold in marla and kanal, a flat in gaj; cement comes in 50 kg bags and rebar is sized by the d²/162 rule. MistriCalc is built around the units and formulas Pakistani construction companies, builders and contractors use from the start.
- Instant & private: everything runs in your browser; nothing you type is stored or sent.
- Order-ready numbers: results round to whole bags, bricks, and bundles so you know what to buy.
- Costs in Rs: every cost tool works in Pakistani Rupees.
These tools give educational estimates. Land-unit factors can vary by region, so always confirm land area against local revenue records, and consult a qualified engineer for any structural design.
