Price. The price of a 30-second commercial in each game's broadcast. Up to 2009 it is the average estimated by Nielsen's ad-tracking service, Monitor-Plus, from the historical table published by TV By the Numbers; from 2010 it is the widely reported price, from the network, ad buyers or the ad-tracking firm Kantar Media, as cited by the sources listed for that year. Networks negotiate with each advertiser, so these are typical prices rather than what every brand paid. Where sources disagree, or the widely quoted figure is higher than the reported average, the note for that year gives both.
Today's dollars. Each price is adjusted with the US Consumer Price Index (CPI-U, Bureau of Labor Statistics series CUUR0000SA0) for the month of the game, and shown in August 2026 dollars.
Viewers. Nielsen's average US audience for the game, from its table of every Super Bowl. Nielsen has widened what it counts over time, adding same-day recordings, Spanish-language simulcasts, out-of-home viewing and streaming, so later years count more of the audience than earlier ones. The note for each year flags these changes.
Per second and per 1,000 viewers. The 30-second price divided by 30, and by the audience in thousands. The calculator assumes other lengths cost the same per second, which networks do not guarantee.
What the price covers. Airtime only. Making the commercial costs extra.
