Hamburger Bun Prices Split Into Two City Tiers
Hamburger bun prices separated into two clear groups on August 13. A standardized 10-bun equivalent averaged $13.20 across four city areas and $7.81 across the other eight—a $5.38 difference.
The split matters beyond a package benchmark. One bun supplied about 57% of the wider Burger Index difference between those two groups, making buns the largest reason their grocery burger costs diverged.
The comparison covers the same 12 tracked city areas. Clayton, North Jackson, East St. Louis, and Westside Jacksonville formed the upper tier; their ordering held above the other eight on July 30, August 6, and August 13.
Four city areas sat above an eight-city cluster
Clayton led at $14.44 per 10-bun equivalent, followed by North Jackson at $13.72 and East St. Louis at $13.56. Westside Jacksonville completed the upper tier at $11.06.
The remaining eight city areas ran from $6.87 in Midtown Houston to $9.11 in South Philadelphia. That $2.24 span was much tighter than the $7.57 distance between Houston and Clayton.
| City area | Price |
|---|---|
| Clayton, MO | $14.44 |
| North Jackson, MS | $13.72 |
| East St. Louis, IL | $13.56 |
| Westside Jacksonville, FL | $11.06 |
| South Philadelphia, PA | $9.11 |
| Rainier Valley Seattle, WA | $8.49 |
| Blossom Valley San Jose, CA | $7.98 |
| Mid-City Los Angeles, CA | $7.85 |
| Ridgewood/Glendale New York, NY | $7.60 |
| North Center/Avondale Chicago, IL | $7.51 |
| West San Antonio, TX | $7.10 |
| Midtown Houston, TX | $6.87 |
The line between the groups narrowed
The same four city areas occupied the top four positions at three recent checkpoints, but the break below them became smaller.
On July 30, Westside Jacksonville stood at $12.25 while the fifth city was $8.04, leaving a $4.21 boundary gap. The gap measured $3.02 on August 6 and $1.95 on August 13.
That change came from movement on both sides. The fourth-place value eased from $12.25 to $11.06, while the fifth-place value rose from $8.04 to $9.11. The two groups remained visible, but their nearest prices moved closer together.
Buns supplied 57% of the wider burger gap
CostInflation’s Burger Cost by City applies one-tenth of the 10-bun price to each double-patty grocery burger, equivalent to one bun. The upper-tier city areas averaged $5.69 per burger, compared with $4.74 across the other eight.
The $5.38 package-price difference therefore added about 54 cents per burger. That was roughly 57% of the groups’ 94-cent Burger Index difference.
Beef patties added about 20 cents to the gap and lettuce added about 11 cents. Pickles, cheese, onions, and condiments made up the rest. Buns were not the only difference, but they were larger than every other ingredient contribution.
The next test is whether the $1.95 boundary between the two groups keeps shrinking. The live hamburger bun price history shows each city area’s daily benchmark, while the Burger Cost by City index shows how buns combine with beef, cheese, produce, and condiments.
