Amazon Prime and Related Programs


Amazon Prime members spend considerably more per year than non-Amazon Prime customers. We estimate that Amazon Prime customers spend approximately $1,340 per year, compared to $708 per year for non-Amazon Prime customers, and account for 56 percent of U.S. product sales. They do so because Amazon Prime customers buy over 50 percent more frequently than non-Amazon Prime customers, and buy more expensive items.

Based on the survey data, we estimate that Amazon Prime (including Amazon Student and Amazon Mom) has approximately 16.7 million members, as of September 30, 2013. Over half of current Amazon Prime members joined in the past year (see chart).

We've seen a significant increase over the estimated 9.7 million members at the end of 2012, from previous analysis of our survey data. 93 percent of members indicate that they will definitely or probably renew their Amazon Prime membership, so these figures suggest strong, sustainable growth.

CIRP based these findings on its survey of 300 subjects who made a purchase at in the three-month period ending November 15, 2013.
