PITTSBURGH — In the unlikely event that your Christmas list this year includes every item mentioned in “The Twelve Days of Christmas,” be prepared to pay nearly $100,000.

Trying to buy the 364 items repeated in all the song’s verses would cost $96,824, an increase of 10.8 percent over last year, according to the annual Christmas Price Index compiled by PNC Wealth Management.

So you might want to try for one of everything. That would cost only $23,439.

The 27th annual holiday index has historically mirrored the national Consumer Price Index, but not this year. The PNC Christmas Price Index grew 9.2 percent from last year, compared with just a 1.1 percent increase in the much broader Consumer Price Index.

Only four of the 12 gifts in the song didn’t go up in price from last year: the pear tree ($149, not including the partridge), four calling birds ($599.96), six geese ($150) and the eight maids-a-milking ($58).
