Last updated September 15, 2026 · National screening observation from the [World Bank ICP 2021 API](https://api.worldbank.org/v2/sources/90/country/IND/classification/PX.WL/series/1501200/time/YR2021/data?format=json) and [ICP data documentation](https://www.worldbank.org/en/programs/icp/data); locality and population from the [GeoNames IN dump](https://download.geonames.org/export/dump/IN.zip) (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 6619347). The PLI is not a city cost/m² rate, current escalation series or tender estimate.

Direct answer

For early house construction cost planning in Navi Mumbai, the World Bank ICP reports a 2021 India construction price-level index of 37.7, with the world equal to 100. This is a national comparison—not a Navi Mumbai INR/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across India in 2021; it does not measure a Navi Mumbai market basket or current house tenders. GeoNames 6619347 records the locality at 19.0368, 73.0158, with snapshot population 2,600,000. That ranks Navi Mumbai 12 of 50 listed places, while Mumbai is the nearest listed peer at about 15 km. Use these facts only to plan the comparable search. Obtain current local rates on a consistent area basis, then reconcile scope, taxes, fees, contingency and escalation. Retain the source, base date and reviewer when local evidence replaces the screening ratio.

What does the 37.7 construction index mean?

The World Bank ICP 2021 construction PLI for India is 37.7, compared with a world benchmark of 100. It is a national spatial price comparison assembled for the 2021 reference year. It does not say that house work in Navi Mumbai costs 0.377 times a current world rate.

Which Navi Mumbai inputs are known?

The reproducible locality point is 19.0368, 73.0158 (GeoNames 6619347). Its snapshot population is 2,600,000, ranked 12 of 50 listed places; GeoNames classifies it as a section of a populated place in administrative area 16. These facts shape the local comparable search, not the price.

What must a project estimate add?

For a Navi Mumbai house project, reconcile dwelling size, structural system, envelope specification, kitchens and bathrooms. Use a consistent gross-floor-area basis and record the following before reliance.

Price-level normalization worksheet

For a validated reference rate R from a country with construction PLI P, the transparent screening calculation is R × (37.7 ÷ P). At P = 100 the dimensionless ratio is 0.377; no world cost rate is asserted. Keep the reference rate's currency, base date, area basis and scope attached.

Sources and method

National screening observation from the World Bank ICP 2021 API and ICP data documentation; locality and population from the GeoNames IN dump (CC BY 4.0 snapshot 2026-08-26, GeoNames ID 6619347). The PLI is not a city cost/m² rate, current escalation series or tender estimate.

Frequently asked questions

Does the 37.7 index give a house cost per m² for Navi Mumbai?

No. 37.7 is the World Bank ICP 2021 national construction price-level index for India, with the world equal to 100. It is a cross-country screening statistic, not a Navi Mumbai INR/m² rate, escalation index, quote or tender estimate.

How should a Navi Mumbai house estimate replace this screening benchmark?

Collect current Navi Mumbai comparables on a consistent gross-floor-area basis, reconcile dwelling size, structural system, envelope specification, kitchens and bathrooms, and state base date, currency, taxes, fees, site work, contingency and escalation. A qualified local cost professional should review the resulting project estimate.
