Cheeseburger Ingredient Price Tracker

What is really driving the cost of your cheeseburger? This page tracks the monthly retail price of every ingredient — ground beef, American cheese, white bread, iceberg lettuce, and tomatoes — using data from the U.S. Bureau of Labor Statistics CPI Average Price Data program. Each ingredient links to a full price history with a decade or more of data.

What These Prices Measure

The five ingredients on this page are the entire homemade cheeseburger basket: a 1/3 lb 80%-lean beef patty, a 1 oz American cheese slice, a 2 oz white bun, 1 oz of iceberg lettuce, and a 2 oz tomato slice. Every retail price is a national monthly average reported by the BLS as part of the official Consumer Price Index, drawn from the agency's ongoing survey of thousands of retail outlets. Prices are quoted per pound for all five items, which makes per-burger cost a simple weight calculation.

BLS pricing methodology is the same one the Federal Reserve watches when judging food inflation, and the USDA Economic Research Service uses the same retail data for its food cost reports. Because the inputs are public domain, every number on this page can be reproduced from the official BLS time series IDs (APU0000703112 for ground beef, APU0000710212 for American cheese, APU0000702111 for white bread, APU0000FL2101 for iceberg lettuce, and APU0000712311 for field tomatoes).

Why the Five Ingredients Move Differently

Beef is the largest line item in the burger and the most volatile. Ground beef prices respond directly to U.S. cattle inventory, which has been at multi-decade lows. Cheese prices follow milk supply contracts and tend to lag dairy spot markets by a quarter. Bread is the most stable of the five because wheat is a globally traded commodity and U.S. bakeries forward-contract flour. Lettuce and tomatoes are the most seasonal items: California and Arizona produce most of the iceberg consumed nationally, and a single weather event in either growing region can move the BLS price by double digits within a month.

That structural diversity is why the composite cheeseburger index is a more useful inflation signal than any single ingredient. When beef spikes but produce falls, the homemade burger rises only modestly. When everything moves in the same direction, it is usually a sign of broader food inflation that the BLS CPI program will pick up across the food-at-home basket as well. Watching the five ingredients in parallel makes the underlying drivers of any given month's move visible.

Today's Snapshot

Right now the most expensive ingredient per pound is Ground Beef (80% lean) at $6.70, and the cheapest is White Bread at $1.81. The biggest 12-month mover is Tomatoes (+24.0% year-over-year), while White Bread has moved -3.8%. Click any ingredient below to see its full retail price history and a long-run chart.

How Each Ingredient Slots Into the Burger Cost

On a per-pound basis the most expensive ingredient is rarely the largest line item in the burger, because the recipe weights matter. Ground beef occupies one-third of a pound per burger, which is the largest single weight in the basket and is why it always carries the largest dollar contribution even when its per-pound price is in the middle of the pack. American cheese is priced per pound but only one ounce ends up on each burger, so a relatively expensive cheese price translates into a small absolute contribution. White bread and lettuce are similarly modest contributions. Tomatoes, at two ounces per burger, can become a meaningful share of the total when seasonal pricing pushes the per-pound figure to the high end of its historical range.

That weighting means the homemade cheeseburger is, in practice, mostly a beef-price gauge with a four-ingredient supporting cast. Months when ground beef sets new highs almost always show up as new highs in the composite index too. Months when beef pulls back even modestly tend to ease the index meaningfully, even if cheese, bread, lettuce, or tomatoes are simultaneously rising. Watching the per-pound prices on this page makes that interaction visible: when beef and another ingredient move in the same direction, the index outruns either one individually. When beef and another ingredient diverge, the per-burger total moves only modestly.

A Closer Look at Each Ingredient's Price Behavior

Ground beef is the largest and most volatile component. Beef prices respond to the size of the U.S. cattle herd, the cost of corn and soybean meal used as feed, the capacity of beef processing plants, and the timing of cattle slaughter cycles. When the U.S. cattle herd contracts to multi-decade lows, ground beef sets new highs and stays elevated for years rather than months because herd rebuilding is biologically slow. When feed costs spike, cow-calf operators retain heifers longer and reduce slaughter, tightening near-term beef supply and pushing retail prices higher even before the herd-size effect fully plays out. Watching ground beef alone explains most of the month-to-month variation in the composite cheeseburger cost.

American cheese is the second-largest dollar component but moves more slowly. Dairy producers contract milk supply months or quarters in advance, and processed cheese pricing is set by long-term contracts between dairy cooperatives and food manufacturers. As a result, cheese prices tend to move in step changes rather than smooth trends, with months of stability punctuated by larger annual contract resets. White bread is the most stable of the five because flour, yeast, oil, and packaging are all forward-contracted by industrial bakeries, and wheat itself is a globally traded commodity with deep liquidity. Bread prices typically move only when energy costs, which feed into both wheat farming and bread distribution, move materially.

Iceberg lettuce and field tomatoes are the most seasonally volatile items in the basket. California's Salinas Valley supplies the bulk of U.S. iceberg from spring through fall, with Yuma, Arizona taking over in the winter. A single freeze in either growing region, or a transportation disruption between them, can move retail iceberg prices by double digits in a single month. Tomatoes follow a similar pattern, with field tomato production concentrated in California, Florida, and Mexican imports during the winter months. The BLS series captures the realized retail outcome of these supply shifts each month, which is why lettuce and tomato prints can swing dramatically even when broader food inflation is stable.

Why These BLS Series Are the Right Sources

Several alternative pricing sources exist for U.S. retail food. Grocery scanner datasets capture more granular price movements but are licensed and expensive, and their methodology is opaque. State-level produce boards publish wholesale prices that do not reflect what consumers pay at the register. Online grocery aggregators offer real-time pricing but vary in coverage and are not designed for time-series analysis. The BLS Average Price Data series we use is the one source that is monthly, regional, public-domain, and continuous over decades. That is why the BLS CPI program uses these same series as part of its food-at-home inflation methodology, and why the Federal Reserve uses them for its policy analyses.

All Five Ingredients, Ranked by Acreage in the Burger

How These Prices Roll Up Into the Burger Index

Each ingredient's monthly retail price is multiplied by the amount used in a single homemade cheeseburger and summed. That sum is the per-burger cost reported on the homepage and the regional pages. We never substitute, smooth, or seasonally adjust these inputs — every published number traces directly back to a BLS series ID and a publication date.

Why do ingredient prices vary so much month-to-month?

Retail food prices respond to a mix of forces: cattle herd size and feed costs drive ground beef, dairy supply contracts move cheese pricing, wheat and energy costs flow into bread, and produce prices swing with seasons and weather. The BLS Average Price series captures the realized retail outcome of all these forces in a single monthly number.
