Your next soda run may cost more even before you get to the checkout math. The Bureau of Labor Statistics said the U.S. consumer price index for carbonated drinks was up 4.4% in August 2026 from a year earlier, and up 1.2% from July.
That shelf price is only part of what changed. Coca-Cola has been expanding smaller 7.5 ounce mini cans in the United States, a packaging move the company says gives shoppers more choice and a lower upfront price, even as it changes how much drink comes in each unit families buy.
A higher price tag, and a smaller package in more places
The clearest national number comes from the Bureau of Labor Statistics. In its August 2026 CPI release, the agency said carbonated drink prices rose 4.4% over 12 months and 1.2% over the month. That means soda inflation is still running ahead of many shoppers’ sense that prices should have cooled by now.
Coca-Cola has also kept leaning on pricing. In its second quarter 2026 results, the company said net revenues grew 7% to $13.4 billion and organic revenue grew 6%, driven by a 4% increase in concentrate sales and 2% growth in price and mix. The company said that price and mix gain was driven primarily by pricing actions in the marketplace, partly offset by unfavorable mix.
Package size is part of that mix. Coca-Cola said its 7.5 ounce mini can single serve carries a suggested retail price of $1.29. The company also said the package joined a convenience store lineup that includes a 16 ounce can, a 20 ounce bottle and a 24 ounce bottle.
The shoppers feeling it most are the ones buying for price, not by ounce
The smaller can is new in one important way. Coca-Cola said mini cans had long been sold in multipacks, but single serve 7.5 ounce mini cans began coming to U.S. convenience stores on January 1, 2026. That matters because convenience stores are a common stop for immediate purchases, where shoppers often compare the cash price in front of them, not the per ounce cost.
Coca-Cola said the mini can single serve is meant to fit “changing habits.” Joel Bishop, president of commercial leadership for the company’s North America operating unit, said people want more ways to enjoy Coca-Cola “on their terms,” including a smaller portion. The company also said mini cans now account for more than 9% of sparkling soft drink mix in large stores.
For grocery shoppers, the effect is less about one national shelf price and more about how households buy. A family grabbing multipacks for the week is watching total cart cost. A commuter stopping at a convenience store may see the lower cash outlay on a mini can and accept a higher cost per ounce. Prices also vary by retailer and region, and Coca-Cola’s $1.29 figure is a suggested retail price, not a guaranteed store price.
Why companies are using price and pack size together
Manufacturers have been explicit that pricing remains part of the strategy. Coca-Cola said in the second quarter that pricing actions helped drive price and mix growth, while higher input costs also affected results. PepsiCo has described a similar dynamic in North America, though with more emphasis on affordability. In prepared first quarter 2026 remarks, PepsiCo said PepsiCo Beverages North America organic revenue grew 2% while organic volume declined 2.5%.
That combination helps explain why shoppers can see two changes at once. The ticketed price can rise across the category, while the package itself shifts toward smaller sizes that lower the amount paid at one time. Academic research published in Marketing Science in 2026 found that package downsizing in U.S. retail grocery often leaves consumers paying more per volume when prices do not fall proportionally.
For home kitchens, the practical effect is simple. The can in the fridge may be smaller, the trip cost may still be higher, and recipes or party planning built around older pack assumptions may no longer stretch the same way. As of August 2026, the government data still showed carbonated drink prices moving up, not down.
