The ACEIT Inflation Utility is an Excel Add-in program that allows you to inflate costs in an Excel spreadsheet. The inflation utility uses the same database of inflation indices that ACE uses. You can choose either the ACE system database, which contains OSD rates for all the services, or a user-created custom database, which contains custom indices entered using the Inflation Editor.

The utility can convert costs from base year (constant) dollars in one year to base year dollars in another year, base year dollars to then year (current) dollars, then year dollars to base year dollars, and then year dollars to then year dollars.

The ACEIT Inflation Utility is included with the ACEIT application suite.
