Cooper Product Index (CPI–3)
The price adjustment calculation is based upon the percentage content of price for each of the key components. The weighting factors for each product are defined below.
The CPI Calculation: Customer Base Net Price multiplied by (1+CPI Value) = Adjusted Net Price
Example: If customer Base price is $1,000 and the current CPI value is 6.5% the Adjusted Net Price equals $1,065. ($1,000 X 1.065 = $1,065). The incremental price change from the price index is $65.
