Method
Each cost share of the item in its market times the move of the index that drives it, from the old price's month to the newest value, summed. The range comes from how sure the shares are: shares from Census or Eurostat statistics count ±15 %, estimates ±40 %. Quarterly and half-yearly series aren't seasonally adjusted, so they compare the average of the year up to each month. The producer price index of the industry shows what producers of this charged over the same months. A reference, not a quote. Newest data: 2026-09.
