16% Trimmed-Mean Consumer Price Index (CPI) is a measure of core inflation calculated by the Federal Reserve Bank of Cleveland. The Trimmed-Mean CPI excludes the CPI components that show the most extreme monthly price changes. This series excludes 8% of the CPI components with the highest and lowest one-month price changes from each tail of the price-change distribution resulting in a 16% Trimmed-Mean Inflation Estimate.
