This India stamp duty calculator estimates the registration cost on a property purchase: the state stamp duty (a percentage of value) plus the registration charge (usually 1%). Because stamp duty is a state subject, the rate you pay depends entirely on where the property is, so the tool lets you set the rate and any female-buyer concession.
How it works
Stamp duty is charged on the higher of the agreement value or the government circle / ready-reckoner rate. The duty is:
stamp duty = value × state rate %
State rates typically range from about 3% to 8%. Many states reduce the rate by 1–2 percentage points when the buyer is a woman, so the tool subtracts a concession when you select a female buyer. On top of the duty sits a registration charge, usually 1% of value (a few states cap it at a fixed amount).
The total registration cost is stamp duty plus the registration charge, and the all-in outlay is that total added to the price.
Example
On a ₹50,00,000 flat at a 6% stamp duty rate, duty is ₹3,00,000 and the 1% registration charge is ₹50,000, for a total registration cost of ₹3,50,000 — about 7% of the price. If a state offers a 1% female-buyer concession, the rate drops to 5%, cutting stamp duty to ₹2,50,000.
Notes
This is an estimate. Some cities add a local body tax or metro cess on top of the state rate, and a few states cap the registration charge rather than charging a flat 1%. Always pay duty on at least the circle rate, and confirm the current figure with the sub-registrar before registration.
