Big Mac index - the cost of a burger in McDonald's network. Big Mac contains meat, vegetables, cheese, bread and other foods. It also includes the cost of renting space and equipment, labor, and other factors. If the price of a Big Mac low then we can say that the prices in the country are low, even if the high prices are relatively high. At that time the US Big Mac was $3.57 and the Big Mac in Mexico was $2.39. Due to the huge drop in the value of the Mexican peso, it is now an even better time to visit or move to Mexico. Some of the other Big Mac values in January 2017 were: Argentina $3.47, Canada $4.51, Colombia $3.31, Costa Rica $4.06, Peru $3.24, and Uruguay $4.35. The "Big Mac Index" is a playful guide to global exchange rates that the Economist puts out every January using data from the previous year. It is designed to measure purchasing power parity (PPP) between nations, using the price of a McDonald's Big Mac as the benchmark. It is a flawed method. It is light-hearted. Don't go crazy.
