U.S. e-commerce sales totaled $83.86 billion during the second quarter, up 14.1% from $73.49 billion a year ago, according to seasonally adjusted estimates released today by the U.S. Commerce Department.

Total retail sales, by contrast increased 1.0% from the second quarter of 2014, and web sales accounted for nearly all of the growth. After removing e-commerce growth, all other retail sales increased only .14% in the second quarter of 2015 versus the prior-year quarter. Compare this to how Q2 looked last year. 

E-commerce accounted for approximately 7.2% of total retail sales during the second quarter, its highest level on record, the Commerce Department says. Total adjusted retail sales, excluding foodservice, during the second quarter reached $1.17 trillion, according to today’s report.

When further excluding sales of automobiles and fuel—goods not commonly bought online—Internet Retailer calculates that e-commerce accounted for 9.2% of total retail sales during the quarter.

On an unadjusted basis, the Commerce Department says e-retail sales excluding foodservice during the second quarter totaled $78.75 billion, up 14.4% from $68.86 billion a year ago. It says e-commerce accounted for approximately 6.6% of the quarter’s unadjusted total retail sales of $1.19 trillion. Following the same method outlined above, Internet Retailer calculates e-commerce accounted for 8.6% of unadjusted retail sales of items consumers often purchase online.

For the first six months of the year, adjusted e-commerce sales total $164.31 billion or 7.1% of total retail sales (excluding foodservice) of $2.32 trillion. On an unadjusted basis, web sales for the first six months of the year total $143.59 billion, or 6.2% of total retail sales (excluding foodservice) of $2.29 trillion.
