Cost of living is the amount of money a household needs to maintain a particular standard of living in a particular place. It is influenced by housing, transportation, food, health care, taxes, utilities, insurance, and many other expenses.
Why cost of living is personal and local
Two households with the same income can face very different costs. A family paying for childcare and commuting by car has a different spending pattern from a retired household with a paid-off home. Geography matters too: housing, insurance, taxes, utilities, and transportation vary substantially across areas.
The biggest cost categories
Housing
Housing often represents the largest monthly expense. Rent or mortgage payments are only part of the picture. Property taxes, insurance, utilities, maintenance, homeowners-association dues, and commuting costs can change the true cost of a location.
Transportation
Vehicle payments, fuel, insurance, maintenance, registration, parking, and depreciation can be substantial. A cheaper home farther from work can still produce a higher combined housing-and-transportation cost.
Food and household needs
Food costs vary by household size, dietary needs, location, and how often meals are prepared at home versus purchased away from home.
Health care and insurance
Premiums, deductibles, copays, prescriptions, and uncovered services can make health costs highly household-specific.
Taxes
State and local income taxes, sales taxes, property taxes, and other levies can affect disposable income and purchasing power. Comparing salaries without considering taxes can create a misleading picture.
Cost of living vs. inflation
Inflation describes how prices change over time. Cost of living asks how much it takes to support a standard of living. BLS explains that CPI is often called a cost-of-living index, but it differs from a complete cost-of-living measure.
In August 2026, CPI-U was 3.4% higher than a year earlier. That national number is useful for tracking broad inflation, but BLS also notes that individual households can experience different inflation depending on what they buy.
Why salary comparisons need adjustment
A job paying $80,000 in one metro area may provide a different standard of living from the same salary in another. To compare offers, consider:
- after-tax income,
- housing,
- transportation,
- childcare,
- health insurance and medical costs,
- local utilities,
- insurance costs, and
- the value of employer benefits.
A practical comparison method
Instead of relying on one “cost-of-living score,” build a household-specific comparison:
- List your current major expenses.
- Estimate the same categories in the new location.
- Separate one-time moving costs from recurring expenses.
- Adjust expected take-home pay for taxes and benefits.
- Stress-test housing and transportation because they are often the largest differences.
- Include savings goals so a higher salary is not automatically treated as more spendable income.
What national data are good for
National and regional data can establish context. BLS CPI shows price changes; Census data can help with income and housing characteristics; BEA publishes regional economic and income data. But a household decision still requires your own numbers.
