How much would it cost you to live in New York? In L.A.? CNN offers a cost-of-living comparison calculator.

Use this calculator to compare the cost of living between U.S. cities. Select the city you’re in and the city you’re moving to. Enter your present income and click “Refresh listing.” The income required to maintain your current standard of living will appear in the box below, along with the percentage difference between the two cities. The calculation takes into account dozens of items in six broad categories — groceries, housing, utilities, transportation, health care and miscellaneous goods and services. It does not include the effects of state and local taxes

This is a useful tool if you’re planning to move, but it’s also fun just to play with to see how much your current standard of living would cost in, say, North Dakota.
