Why these calculators are different
- India-first rules: stamp duty per state with women-buyer concessions, bigha and biswa by region, GST on under-construction homes, section 194-IA TDS, post-2024 capital gains.
- Exact where others approximate: irregular plots use a diagonal and Heron\'s formula, not the average-of-sides shortcut.
- Every page shows its working: formula, assumptions, a worked example and the official source to verify against.
- Open API: every calculator answers at
