How to compare cost of living between cities
We won't publish a made-up "cost of living index" here — the real numbers change constantly and are better sourced from dedicated data providers. What we can do is walk through how to actually use that data well, since most people compare cities badly even with good numbers in front of them.
Where to find real, current numbers
- The U.S. Bureau of Labor Statistics publishes regional price parity data by metro area
- The Council for Community and Economic Research (C2ER) runs a cost-of-living index widely used by relocation professionals and HR departments
- Local Chamber of Commerce or economic development sites often publish current housing and utility cost data for their specific city
Treat informal "cheapest cities to live" listicles with caution — many recycle outdated or loosely sourced numbers.
Categories that matter beyond housing
- State and local taxes — can shift real take-home pay significantly; see our state income tax guide
- Healthcare and insurance costs — vary meaningfully by region and aren't always reflected in general cost-of-living indexes
- Childcare — one of the most variable costs between metros, and a major line item for families
- Transportation — a car-dependent city adds a real ongoing cost that a walkable or transit-served city doesn't
What cost-of-living calculators tend to miss
These tools compare like-for-like costs — a gallon of milk, a square foot of housing — but don't account for lifestyle norms shifting between cities. A smaller apartment might be completely normal in one city and a real downgrade in another; a car might be optional in one place and effectively required in another. Use the index as a starting point, not a final answer.
Using cost-of-living data for a salary comparison
For a job-driven move, a cost-of-living calculator gives a reasonable starting estimate of what a salary needs to be to maintain your current lifestyle elsewhere — but treat the output as a rough guide, not an exact number. Your actual take-home difference depends heavily on your specific tax situation, housing choices, and lifestyle, not just the index figure.
Frequently asked questions
Where can I find real cost-of-living data, not just a general 'cheap' or 'expensive' label?
The U.S. Bureau of Labor Statistics publishes regional price data, and the Council for Community and Economic Research (C2ER) runs a well-regarded cost-of-living index used by relocation professionals — both are more reliable than informal city-ranking articles.
Is housing the only category that matters?
No — housing is usually the biggest line item, but taxes, healthcare, insurance, childcare, and transportation costs can shift the real comparison significantly, especially between states with very different tax structures.
Do cost-of-living calculators account for lifestyle differences?
Generally not well — they compare like-for-like costs (a gallon of milk, a square foot of housing) but don't account for a smaller apartment being normal in one city and unusual in another, or a car being optional in one place and required in another.
Should I compare salary offers using a cost-of-living calculator?
It's a reasonable starting point for a job-driven move, but treat the output as a rough estimate, not an exact figure — actual take-home difference depends heavily on your specific tax situation and lifestyle, not just the index number.
