Buyers know the ready reckoner as the stamp duty floor. Developers should know it as something bigger: the single government table to which Maharashtra has, rule by rule, tied most of the price of buildable area. When the ASR moves, it does not move one line of your pro forma; it moves five at once, and the 2025 revision demonstrated the mechanism on live projects. This data story follows one revision through a model project.
Key takeaways
- Five cost lines key off the ASR: premium FSI, Mumbai's fungible premium, UDCPR's ancillary premium, TDR indexation, and stamp duty on the land documents themselves.
- FY 2025-26 raised rates 3.39 percent on state average (Pune MC 4.2, Pimpri-Chinchwad 6.7, Solapur 10.17); FY 2026-27 froze them.
- Because the paid layers can exceed base FSI in a modern stack, the reckoner's effective weight in project cost keeps rising with density.
- Revision timing is a real planning variable: commitments straddling 1 April carry rate risk that freeze years eliminate.
The five lines, traced
Premium FSI. Purchased from the authority at percentages of the ASR land rate, in Mumbai's stack and UDCPR's alike. The largest single reckoner-linked cheque on most dense projects.
Fungible area (Mumbai). The up-to-35-percent allowance, priced off the reckoner; on suburban towers it is routinely the second premium cheque.
Ancillary FSI (rest of state). Up to 60 percent for residential, again at reckoner-linked premiums, the line that made the ASR a statewide developer tax rather than a Mumbai one.
TDR indexation. Certificate utilisation adjusts by the generating and receiving plots' ASR ratio, so a revision reshuffles the entire TDR market's relative prices in one notification.
Stamp duty. The land purchase, the development agreement, the JV documents: all stamped on reckoner-floored values.
One revision through one project
Take an illustrative Pimpri-Chinchwad parcel modelled in March 2025: base FSI exhausted, assembly plan of premium FSI plus ancillary at reckoner-linked rates. The FY 2025-26 revision landed 6.7 percent on PCMC's rates on 1 April.

The compounding is the point: on a project where paid layers (premium, ancillary, indexed TDR) roughly match base FSI in quantum, a 6.7 percent ASR move flows through multiple premium lines at once, and the all-in land-plus-entitlement cost per sellable metre steps up by several percent in a single notification, before a brick moves. Developers who had committed premiums in March banked the difference; those who assumed April pricing in February bids discovered their margin had a policy exposure nobody had underwritten. And FY 2026-27's freeze cut the other way: a full year of assembly arithmetic that holds still, which is precisely when premium-heavy commitments are cheapest to schedule.
An analogy: the crude price of construction
Airlines do not control crude, but no airline models a route without a fuel-price assumption and a hedge posture. The ASR is development's crude: administratively set, revised on a known calendar (1 April, when revised at all), moving several cost lines simultaneously. The professional posture is the airline's: an explicit reckoner assumption in every pro forma, sensitivity runs at plus 5 and plus 10 percent, and commitment timing treated as the only hedge on offer.
The planning disciplines that follow
- Date-stamp the pro forma's ASR assumption, and re-run the feasibility stack the day any revision notifies.
- Front-run known revisions where lawful: premium commitments and stampable documents concluded before 1 April of a revision year price at the old table.
- Exploit freeze years for premium-heavy assembly, FY 2026-27 being the live example.
- Watch the micro-geography. Revisions are locality-specific: the same notification moved PCMC 6.7 and Mumbai 3.39, so portfolio exposure varies parcel by parcel, and so does the launch pricing your micro-market will bear afterward, since new supply tends to pass reckoner-driven cost steps into asking prices with a lag.
The reckoner cuts one way for costs and another for evidence: because premiums and duty are computed on it, the ASR table is also the one public, dated price surface for every micro-market in the state, imperfect but universal, and useful as the deflator when comparing land quotes across localities.
ReraGenie's area consolidated reports pair that price surface with the register's filed supply and absorption for any Maharashtra micro-market, and the Rs 2,999 project analysis prices a specific parcel's competitive set, the demand side of a spreadsheet whose cost side the government publishes every April.
The one-line summary
Five cost lines, one table: assume the reckoner explicitly, run the sensitivities, time commitments around revisions and freezes, and treat every 1 April notification as what it is, a repricing of buildable Maharashtra, published in advance for whoever reads it.
