The Christmas Price Index is a tongue-in-cheek economic indicator, maintained by the U.S. bank PNC Financial Services, which tracks the cost of the items in the carol "The Twelve Days of Christmas."


The Christmas Price Index was conceived by the bank's chief economist as a humorous commodity price index to measure the changing cost of goods over time. Commodity price indices, as compiled by economics, use a "market basket" of certain goods and then measure the cost of the goods from year to year to gauge inflation in different sectors of the economy.
The Christmas Price Index chose the items in the popular Christmas carol "The Twelve Days of Christmas" as its market basket: a partridge in a pear tree, two turtle doves, three French hens, four calling  birds, five gold(en) rings, six geese, seven swans, eight maids, nine dancing ladies, ten leaping lords, eleven pipers, and twelve drummers. According to tradition, the purchasing of the items begins on December 26 and ends on January 6.


PNC compiles both a "Christmas Price Index" and "The True Cost of Christmas." The "Christmas Price Index" is calculated by adding the cost of the items in the song. The "True Cost of Christmas," however, is calculated by following the exact instructions in the song (buying a partridge in a pear tree on each of the twelve days, buying two turtle doves from the second day onward, for a total of 22 turtle doves, etc.) for the complete set of 364 items.
The price of each item is set as follows:
The pear tree comes from a local Philadelphia nursery
The partridge, turtle dove, and French hen prices are determined by the Cincinnati Zoo and Botanical Garden
The price of a canary at Petco is used for the calling  bird, though the price of a blackbird (colly bird) would be more in tune with the song
Gordon Jewelers sets the cost of the gold rings, though the gold rings of the song actually refer to ring-necked pheasants
The National Aviary in Pittsburgh sets prices for swans and geese
The maids are assumed to be unskilled laborers earning the Federal Minimum Wage
A Philadelphia dance company provides estimates for the salary of "ladies dancing"
The Philadelphia Ballet estimates the salary for the "leaping lords"
The going-rate for drummers and pipers is that of a Pennsylvania musicians' union


Like other light hearted economic indicators, such as The Economist's Big Mac Index which tracks the price of the Big Mac hamburger in different countries, the Christmas Price Index nevertheless produces results which have meaningful interpretations.
In general, the prices in the index have reflected the United States's growing service economy—prices for goods have mostly fallen, but prices for labor have risen greatly. The cost of hiring ladies and lords, for example, has risen over 300 percent. After the high cost of the dancers, the seven swans are the most expensive item on the index; the unpredictable breeding cycle of swans makes their supply uncertain. Much as the United States Consumer Price Index excludes volatile energy and food prices from its "core" index, the core Christmas Price Index excludes the swans; for 2008, the total price index rose 8.1% from 2007, while the core index rose only 1.1%. The cheapest item in the index is the partridge, which, in 2008, could be purchased for $20. Costs have generally risen and fallen along with the standard Consumer Price Index.
The survey also tracks the cost of ordering the items online; doing so is significantly more expensive, in part due to shipping costs. In 2008, PNC estimated the total cost at $31,956.62, up 2.3% from 2007, while purchasing all 364 items online would cost $131,150.76, an increase of 1.8%. However, if the buyer were to purchase each item from the least-expensive vendor, the total index would be $19,844.95, a discount of 5.86%.
