Real vs. Nominal Prices
Nominal prices are the actual dollar amount you pay today; real prices are adjusted for inflation to compare purchasing power across different time periods.
How It Works
The distinction between real and nominal prices is critical for understanding whether food is actually becoming more or less affordable. A pound of ground beef cost $1.30 in 1990 and $5.50 in 2024 — nominally, it has increased 323%. But after adjusting for overall inflation using the CPI deflator, the real increase is about 55%, meaning beef has genuinely become more expensive relative to other goods, but not nearly as dramatically as the nominal price suggests. The Cheeseburger Index primarily reports nominal prices because that is what consumers experience at the checkout. When the index shows a burger costing $3.29, that is the actual dollar amount you need today. However, for historical comparisons, real prices are more meaningful. In real (inflation-adjusted 2024 dollars), a homemade cheeseburger cost roughly $2.80 in 2010 and $3.29 today — a real increase of about 17.5%. This matters because wages have also risen: the median hourly wage was $16.30 in 2010 and $23.00 in 2024, meaning the "wage-to-burger ratio" (minutes of work needed to buy a burger) has actually improved slightly despite the nominal price increase. The BLS publishes both nominal average prices and CPI index values, allowing researchers to convert between real and nominal using standard deflation methods.
