Transparent index calculation

Update a construction estimate

Enter two comparable values from an official index. RenoAtlas does not invent an inflation rate or local price.

Correct use

  1. Use the same region, building type and series at both dates.
  2. Multiply the historical cost by the target index and divide by the original index.
  3. Separately add scope changes, land, design, tax, financing and contingency.
