Power Circle Ratings are one of the only sources of consumer ratings based on independent and unbiased feedback from a representative sample of verified product and service owners.

How are Power Circle Ratings Calculated?

To calculate Power Circle Ratings, J.D. Power begins with the syndicated study index scores or a specific standard of measurement which can be found, in most cases, in the associated press release. An example of an index score is found in the J.D. Power U.S. Retail Banking Satisfaction Study, where companies are ranked according to overall index scores based upon weighted responses to several survey factors. An example of a specific standard of measurement is found in the J.D. Power Initial Quality Study, where vehicles are ranked according to reported Problems Per 100 vehicles (PP100).

Using these measurements, Power Circle Ratings are calculated based on the range between the product or service with the highest score and the product or service with the lowest score. J.D. Power generates a Power Circle Rating of five, four, three, or two, as outlined below:

5 Power Circles

Among the best

The highest-ranking company or brand in each segment receives five Power Circles*. In highly competitive segments with many companies or brands, multiple companies or models scoring in the top 10 percent of the range from the highest score can also receive five Power Circles, indicating that consumers rate them "among the best" of all companies or models in the survey. However, only the highest-ranking company in each segment receives a J.D. Power award.

4 Power Circles

Better than most

Companies or models scoring 10 percent of the range above the industry or the segment but below the scores for 5 Power Circles receive a rating of 4 Power Circles*, indicating that consumers rate them "better than most" among companies or models in the survey.

3 Power Circles

About average

Companies or models scoring between 10 percent of the range above the industry or the segment and 20 percent below the industry or the segment receive a rating of 3 Power Circles*, indicating that consumers rate them "about average" among all companies or models in the survey.

2 Power Circles 

The rest

Companies or models scoring 20 percent of the range below the industry or the segment receive a rating of 2 Power Circles*, indicating that consumers rate them lower than other companies or models in the survey. J.D. Power does not publish a rating lower than two Power Circles.
