That’s what the Big Mac Index tells us.

The Big Mac Index is a price index published since 1986 by The Economist as an informal way of measuring the purchasing power parity (PPP) between two currencies and providing a test of the extent to which market exchange rates result in goods costing the same in different countries. It “seeks to make exchange-rate theory a bit more digestible.”[1] The index compares the relative price worldwide to purchase the Big Mac, a hamburger sold at McDonald’s restaurants.

The Big Mac index was introduced in The Economist in September 1986 by Pam Woodall[2] as a semi-humorous illustration of PPP and has been published by that paper annually since then. Although the Big Mac Index was not intended to be a legitimate tool for exchange rate evaluation, it is now globally recognised and featured in many academic textbooks and reports.[3] The index also gave rise to the word burgernomics.
