New CPI Index

The “F” in CPI-F stands for “flat” and this index is calculated by taking the overall consumer price index and excluding more items from it, much in the same way that food and energy have been excluded from “core” inflation, the preferred measure amongst Fed economists. For CPI-F, those items that are increasing in price at a rate of more than 1.5 percent would be excluded … along with those items that are increasing in price at a rate of less than 1.5 percent and items whose prices are falling. The index currently stands at 1.5 percent. source
