If you are buying a builder floor in Delhi, the number that decides your stamp duty is not the price you negotiated. It is the circle rate — and for a builder floor specifically, it is calculated differently from a flat or a plot. Most buyers discover this at the sub-registrar’s office, when the figure is higher than they expected.
This guide sets out the actual method, using the rates and rules published in the Delhi Revenue Department’s circle rate notification.
Rates shown are the notified minimum rates. The government also notifies a relaxation from time to time, so the operative figure may be the lower “effective” rate — both are given below, exactly as the notification publishes them. Confirm which applies for your registration date.
What the circle rate actually is
The circle rate is the minimum rate for valuation — the floor value the government places on a property for registration. Stamp duty is charged on whichever is higher: the transaction value or the circle-rate value. This is why an agreement below market rate does not reduce your stamp duty.
The colony category drives everything
Every locality in Delhi falls into one of eight categories, A to H. Category A is the most expensive. The same A–H classification is used by the Municipal Corporation of Delhi, so the category attached to your colony for property tax is the one that governs the circle rate as well.
Official minimum land rates for residential use
Rupees per square metre, as notified by the Revenue Department:
| Category | Minimum rate | Effective rate (after notified relaxation) |
|---|---|---|
| A | 7,74,000 | 6,19,200 |
| B | 2,45,520 | 1,96,416 |
| C | 1,59,840 | 1,27,872 |
| D | 1,27,680 | 1,02,144 |
| E | 70,080 | 56,064 |
| F | 56,640 | 45,312 |
| G | 46,200 | 36,960 |
| H | 23,280 | 18,624 |
How a builder floor is valued — the part most people miss
A flat in a group housing society is valued using the built-up flat rates. A builder floor is not a flat in this sense, and the notification treats it separately: where part of the plinth area — say one floor of an independent property other than a flat — is sold, the relevant minimum land cost is taken for the proportionate plinth area sold, and the minimum cost of construction is applied to that same plinth area.
So the valuation has two components added together:
- Land: the category land rate, applied to the proportionate land share of the floor being bought.
- Construction: the category construction rate, applied to the plinth area, then adjusted by an age factor.
Minimum cost of construction, residential (₹ per sq m)
| Category | Minimum rate | Effective rate |
|---|---|---|
| A | 21,960 | 17,568 |
| B | 17,400 | 13,920 |
| C | 13,920 | 11,136 |
| D | 11,160 | 8,928 |
| E | 9,360 | 7,488 |
| F | 8,220 | 6,576 |
| G | 6,960 | 5,568 |
| H | 3,480 | 2,784 |
Older structures are valued lower through an age factor applied to the construction cost — roughly 0.5 for buildings completed before 1960, rising to 1.0 for those completed from 2000 onwards. A newly built builder floor therefore carries the full construction value while an older one is discounted. This is a genuine reason a newer building’s registry cost can exceed an older one of the same size.
If the floor is used commercially
Commercial use changes the construction rate and multiplies the land component. The notified minimum construction cost for commercial use is:
| Category | Minimum rate | Effective rate |
|---|---|---|
| A | 25,200 | 20,160 |
| B | 19,920 | 15,936 |
| C | 15,960 | 12,768 |
| D | 12,840 | 10,272 |
| E | 10,800 | 8,640 |
| F | 9,480 | 7,584 |
| G | 8,040 | 6,432 |
| H | 3,960 | 3,168 |
The land component is also multiplied — commercial use attracts a substantially higher factor than residential. If a floor has been converted to commercial use, this materially changes the registry cost.
Worked example
Consider a newly completed builder floor in a Category D colony with a plinth area of 150 sq m, using the notified minimum rates:
- Construction component: 150 × ₹11,160 × 1.0 age factor = ₹16,74,000
- Land component: the proportionate land share for that floor × ₹1,27,680
The land share is the variable that changes most between properties, because it depends on the plot size and how many floors share it. Two builder floors of identical size in the same colony can carry different land components for that reason alone — see our guide to builder floor land share.
Why this matters before you agree a price
- Stamp duty is charged on the higher of the two values — so the circle rate sets your minimum cost regardless of your negotiation.
- Banks lend against the lower of value or agreement, and valuation below the circle rate is not accepted for registration.
- An older building may register for less than a new one of the same size, thanks to the age factor.
- Commercial use on the floor multiplies the land component — worth confirming before you commit. See the stamp duty and registration charges for the full cost picture.
How to check the rate for your colony
The A–H category for each colony is published by the Municipal Corporation of Delhi, and the current minimum rates are notified by the Revenue Department. The sub-registrar’s office for your area can confirm the applicable category. For the full area-wise position, see our Delhi circle rate guide, and for the paperwork, the registry process in Delhi.
Rates are revised by notification, so treat any figure you find online — including on this page — as an indication and confirm the operative rate for your colony and registration date before completing a purchase.
The practical takeaway
For a builder floor, the registry value is not simply area multiplied by one rate. It is a land component and a construction component, adjusted for age, and multiplied where the use is commercial. Understanding which parts apply to your floor is what lets you estimate the registry cost before you commit, rather than discovering it at the sub-registrar’s window.
