The Big Mac Index App intends to show whether currencies are at their "correct" value. It was invented by The Economist in 1986. For example, the average price of a Big Mac (Burger) in USA as in July 2014 was $4.80, in China it was only $2.73 (¥16.90) at market exchange rates. So The Big Mac Index says that the Yuan was UNDERVALUED by $43.1% at that time. How To Use It 1. Input the Local Price of the Big Mac Burger. 2. Press the "CALCULATE" button. 3. You will get if the currency of the selected country is Undervalued or Overvalued and which should be the exchange rate (USD Based) for that Burger price. 4. Share the results in Facebook & Twitter.
