Adobe today announced the latest online inflation data from the Adobe Digital Price Index (DPI). In December 2021, online prices increased 3.1 percent year-over-year (YoY) and 0.8 percent month-over-month (MoM). Meanwhile, consumer spending onlinefor all of 2021 reached a record $855 billion, an increase of 9 percent YoY, attesting to the strength of the digital economy overall.
December’s price increases marked the 19th consecutive month of YoY online inflation and followed the record high of November 2021, when online prices increased 3.5 percent YoY. In December, groceries and apparel were standout categories, with grocery prices seeing their highest annual increase in more than a year (4.9 percent YoY, 0.7 percent MoM). Apparel increased 16.6 percent YoY (0.6 percent MoM).
The DPI provides the most comprehensive view into how much consumers pay for goods online. Powered by Adobe Analytics, it analyses one trillion visits to retail sites and over 100 million SKUs across 18 product categories: electronics, apparel, appliances, books, toys, computers, groceries, furniture/bedding, tools/home improvement, home/garden, pet products, jewelry, medical equipment/supplies, sporting goods, personal care products, flowers/related gifts, non-prescription drugs and office supplies.
The DPI is modeled after the Consumer Price Index (CPI), published by the US Bureau of Labor Statistics, and uses the Fisher Price Index to track online prices. The Fisher Price Index uses quantities of matched products purchased in the current period (month) and a previous period (previous month) to calculate the price changes by category. Adobe’s analysis is weighted by the real quantities of the products purchased in the two adjacent months.
“Inflation online is showing no signs of easing, as durable consumer demand is being met with the same, persistent supply challenges that produced over six billion out-of-stock messages online this holiday season,” said Patrick Brown, Vice President, growth marketing and insights, Adobe. “As consumers contend with higher offline prices for everything from gas to rent, they are finding that e-commerce is still a less expensive option when it comes to goods like toys, electronics, and even jewelry.”
In December 2021, 12 of the 18 categories tracked by the Adobe Digital Price Index saw YoY price increases, with apparel rising faster than any other category. Price drops were observed in six categories: electronics, office supplies, jewelry, books, toys, and computers.
On a MoM basis, 13 of the 18 categories saw December price increases, with price drops observed in five categories, including toys, pet products, home/garden, computers, and flowers/related gifts.
Notable Categories in the Adobe Digital Price Index (December 2021)
Groceries: Prices were up 4.9 percent YoY (up 0.7 percent MoM), the highest increase on an annual basis since October 2020, when prices jumped 5.2% YoY. It is the only category that has moved in lockstep with the Consumer Price Index, which captures prices consumers are paying in physical stores.
Apparel: Prices were up 16.6 percent YoY (up 0.6 percent MoM). This is the 9th consecutive month where online prices have risen on an annual basis in a category that typically sees consistent periods of deflation when seasonal discounts kick in.
Appliances: Prices were up 4.1 percent YoY (up 3.0% MoM). This marks the 19th consecutive month of inflation for the category, at a time when consumers are keen to invest in their homes. Over the holiday season (November 1 to December 31), online sales for appliances doubled compared to pre-season (September 2021) levels. Furniture and bedding followed a similar trend, after 20 consecutive months of inflation, where December 2021 prices were up 3.3 percent YoY and up 0.8 percent MoM.
Tools & Home Improvement: Prices were up 7.1 percent YoY (a record high for the category) and up 1.0 percent MoM, marking the 13th consecutive month of online inflation as consumers continue to spend more in this category. Over the holiday season (November 1 to December 31), online sales in the category grew by 1.7 times pre-season (September 2021) levels.
Electronics: Prices were down 2.6 percent YoY (up 0.4 percent MoM). This is a greater price drop compared to November 2021, when prices for products in the category were only down 0.4 percent YoY and nearly moved into inflationary territory for the first time since Adobe began tracking price trends in 2014.
