Frequently Asked Questions
What is a cost-of-living index?
It is a number showing how expensive a place is compared with the national average, which is set at 100. A city at 112 is about 12% pricier than the US average; a city at 90 is about 10% cheaper.
Where does the data come from?
The US Bureau of Economic Analysis (BEA) Regional Price Parities, an official federal dataset that measures local price levels across US metro areas.
How is the 'salary you'd need' figure calculated?
It scales your salary by the ratio of the two cities' price levels. To match a $100,000 lifestyle in a city with index 100 in one with index 112, you'd need about $112,000.
How often is the data updated?
BEA publishes new figures about once a year, usually in December, for the prior year. The site currently reflects 2024 data.
Does this include taxes or salaries?
No. The index measures prices for goods, services, and housing, not income or tax differences. Treat it as a cost-of-living guide, not financial advice.
Is City Compare free?
Yes, completely free to use.
