Producer Price Index (PPI)

How It Works

The Producer Price Index measures price changes from the seller's perspective rather than the buyer's (CPI), making it a useful leading indicator for retail food prices. The PPI for food manufacturing tracks prices at the factory gate — what a meatpacker charges a distributor for ground beef, what a bakery charges for bread, what a dairy processor charges for cheese. Because producer prices are upstream from consumer prices, PPI changes typically lead CPI changes by 1-3 months. When the PPI for meat processing rises, retail ground beef prices will follow, with the lag depending on existing inventory levels and retailer pricing strategies. In 2022, the PPI for food manufacturing peaked at a year-over-year increase of 16.9% — about 5 percentage points higher than the consumer food CPI, indicating that producers were absorbing some cost increases. By mid-2023, the PPI had fallen faster than the CPI, suggesting that consumer food prices had further room to moderate. The Cheeseburger Index tracks consumer prices (from the BLS Average Price program), but monitoring the PPI provides early warning of upcoming ingredient price changes. The PPI is published monthly, typically one day before the CPI release.

• Commodity Prices — The wholesale prices of raw agricultural products like cattle, corn, wheat, and dairy on commodity exchanges — these upstream prices eventually flow through to retail food costs.
• Input Costs — The costs of raw materials, labor, energy, and other resources that go into producing a finished product — rising input costs are a primary driver of food price inflation.
