The cost of living calculator tells you how much money you need to maintain your current standard of living in a different city. The cost of living comparison is based on your income and the price of basic necessities such as housing, transportation or food in the two cities you selected. Use the calculator to find out what income you will need in a new city and how much more or less you’ll need to budget for basic expenses.
