Most Indian buyers walk into a builder office with one number in their head — what the broker quoted them on a phone call. Then the floor plan comes out, the discount drama begins, and within twenty minutes they are nodding at a price that is twelve to eighteen percent above what the surrounding micro-market actually transacts at. The Brickplot Fair Price Calculator was built for exactly this moment. It does not tell you what a builder is asking. It tells you what the locality is selling at — based on registered SRO deeds, recent project launches, and resale closures Brickplot has tracked across 1,800+ projects.
This walkthrough explains how the tool works under the hood, how to read its output, and which inputs actually move the verdict.
What the calculator is actually doing
The calculator sits at brickplot.com/tools/fair-price and runs a four-layer compute on whatever locality, BHK and project tier you give it. It is not a Zillow-style AVM that learns from listing prices — listing data in India is heavily inflated and lies. The calculator reads from three primary sources:
- SRO deed data — Karnataka Kaveri 2.0, Maharashtra IGR, Telangana IGRS — the actual registered sale price after stamp duty was paid. This is the closest thing India has to a transactional truth.
- Brickplot's own project dataset — 1,800+ projects scored across our 11-axis rubric, with launch price, current asking price, and resale-closure price tracked monthly.
- NHB RESIDEX — the National Housing Bank's quarterly residential index — used as a cross-check and trend signal.
The output is a single rupees-per-square-foot fair-price band, plus a deviation flag against whatever quote you pasted in.
The four inputs that change the answer
Most users only fill three fields. The fourth one is where the calculator earns its keep.
| Input | What it changes | Common mistake |
|---|---|---|
| Locality | Pulls the median deed price for the past 90 days within a 2 km radius | Picking a parent area like "Whitefield" instead of "Whitefield — Kadugodi" hides the price differential |
| BHK configuration | 2BHK and 3BHK in the same tower can differ ₹400–₹700 per sq ft on builder loading | Defaulting to 3BHK when shopping a 2BHK |
| Project tier | Premium Plus, Premium, Mid, Affordable — sets the comparable basket | Comparing a Sobha tower to RERA-listed budget projects and getting a falsely low number |
| Construction stage | Pre-launch, under-construction (0–30%, 30–70%, 70–100%), ready-to-move | Skipping this and getting a ready-to-move benchmark for a project that is still in foundation stage |
How to read the output band
The calculator returns three numbers — not one. They matter in this order:
- Fair Price Band (₹X – ₹Y per sq ft) — the 25th-to-75th percentile range from SRO deeds in that locality, BHK, and tier. Anything inside this band is a normal market quote.
- Median Quote (₹Z) — the middle of the deed distribution. Aim for this or below.
- Deviation Flag — if the price you pasted in is more than 8% above the upper bound of the band, the tool flags it red. Above 15%, it suggests walking.
An example from this week. A buyer ran a quote for a 3BHK at a Premium tier project in Hebbal North — builder asking ₹14,200 per sq ft. The calculator returned a fair band of ₹11,400–₹12,600, median ₹12,000. That is a 12.7% premium with no defensible reason — the project is mid-construction, no metro premium yet, no view differential. The buyer walked. Three weeks later the same builder is offering a "festival rate" of ₹12,800.
Where the calculator is conservative — and where it is not
The tool deliberately under-weights three things: pre-launch hype pricing, NRI-sold towers (where deed values are often staged), and "premium floor" loading above the 18th floor. It deliberately over-weights actual SRO deed medians from the past 90 days because those numbers are paid in stamp duty and cannot be easily faked.
What it does not do: it will not give you a fair price for an entirely new sub-locality with fewer than 15 deed transactions in the past 90 days. In those cases the tool returns a low-confidence flag rather than a fabricated number. Honesty over coverage — that is the editorial line.
What to do with the result
Three rules of thumb after running the calculator:
- If the builder quote is inside the band, negotiate to the median, not the lower bound. The lower bound is corner-unit, low-floor, west-facing data — you may not be buying that.
- If the quote is above the band by 5–10%, ask the builder to itemise the premium — clubhouse, view, floor-rise, infrastructure development charge. Half of those line items are negotiable.
- If the quote is above the band by more than 12%, walk and recheck in 30 days. In our dataset, 60%+ of these projects come back to fair-band pricing within a quarter, especially in oversupplied micro-markets like New Gurgaon, Sarjapur Road, and parts of Hyderabad ORR.

Then run it side-by-side against your project's full Brickplot score to see how price stacks against legal, builder, and liveability axes — because a fair price on a flood-zone plot with a stalled RERA is still a bad buy.
