Winter 2010 NAGS Calculator Published; Shows 0.81 Percent Decrease in Weighted Average of All Parts
December 18, 2009

The 2010 calculator from National Auto Glass Specifications International (NAGS) has been released, and the latest calculator shows a 0.81 percent decrease in weighted average from the previous calculator, released in September 2009. The newest calculator becomes effective on January 11, 2010.

To calculate the weighted average, NAGS weighs parts according to popularity (i.e., more popular parts have a higher weight than those used less frequently used, in an effort to achieve a more accurate average than a blanket, overall average might show).

Among the top 100 parts, the calculator shows a 0.44 percent drop from the fall calculator, and a 0.49 percent drop among the top 500.

A .72 percent decrease can be seen from when comparing the top 1,500 parts with the previous calculator, when looking at the parts' weighted averages.
