The Big Mac index is an index based on the relationship between the price of one of the most popular sandwiches at McDonald's and consumer earnings. It was invented in the 1980s by the British. Poles could create their index. Only that one determines the amount of inflation based on the Lumberjack burger. Few goods have changed in value so much in a year, and to the detriment of buyers.
Consumer inflation in October reached almost 18 percent. Store inflation, that is, that of food prices, is a little over 20 percent. It is well known that food service is not based on food alone, because the cost also includes the number of wages of employees or the price of electricity. McDonald's added up all these components and came up with a figure that its inflation rate will be slightly higher than what we've learned so far.
In the case of the Lumberjack, it exceeds a hefty 40 percent. In the case of the classic version, the burger has risen from PLN 17.40 to PLN 24.90. In the variation with either cranberry or double meat, the price increase is 47 percent, from PLN 17.90 to PLN 26.40 and from PLN 20.40 to PLN 29.90, respectively.
