ISGuides: Chemical and Process Engineering: Adjusting older costs

What are Cost Indexes?

Cost indexes can be used to adjust older prices to the current day. They do not list prices, but instead help you calculate what ratio to use to estimate current prices based on historical data.

Chapter 9 of Perry's Chemical Engineers Handbook explains how to use cost indexes.
