About HisabCalc

HisabCalc builds free calculators for the decisions Indians actually make: buying a plot or flat, taking a home loan, understanding a salary offer, choosing a tax regime, and planning construction.

Instead of hundreds of disconnected tools, we connect calculators into journeys. A property buyer can move from plot size to purchase cost, stamp duty, TDS, EMI, prepayment and rental yield in one flow.

Every formula is covered by automated tests. Tax slabs, stamp duty rates and land units live in a versioned rules engine with the official source, effective date and last review date shown on the page.

Rates that have not yet been verified against an official notification are clearly labelled as pending verification.

Calculations run in your browser. We never send the amounts you type to our servers or to analytics.
