Cost of Living Comparison Guide: Comparing Salaries Across US Cities

A $100,000 salary means very different things in San Francisco versus San Antonio. This guide explains how to compare the true cost of living across US cities so you can make smarter decisions about job offers, relocations, and remote work.

What Is Cost of Living?

Cost of living refers to the amount of money needed to maintain a particular standard of living in a given location. It encompasses housing, food, transportation, healthcare, taxes, utilities, and everyday goods and services. Two people earning identical salaries in different cities can have vastly different lifestyles because of cost of living differences.

The most common way to measure cost of living is through an index โ€” a number that compares one location to a baseline (usually the national average at 100). A city with an index of 130 is 30% more expensive than average, while one at 80 is 20% cheaper.

The Major Cost Categories

Cost of living is not a single number. It is made up of several categories, each of which can vary independently. Understanding the components helps you make a more nuanced comparison.

Housing (30-40% of the Difference)

Housing is by far the largest cost of living differentiator between US cities. It includes rent or mortgage payments, property taxes, homeowners or renters insurance, and maintenance costs. In most comparisons, housing accounts for 30-40% of the total cost of living variation.

Some examples of how dramatically housing varies:

When comparing housing costs, consider whether you plan to rent or buy. In some markets, buying is relatively more affordable than renting (and vice versa). Also factor in property tax rates, which range from under 0.5% (Hawaii) to over 2% (New Jersey, Illinois, Texas).

Taxes (10-20% of the Difference)

State and local taxes create significant cost of living differences that salary comparisons often overlook. The key tax categories are:

Groceries and Food (10-15% of the Difference)

Grocery prices vary by 10-30% across US cities. Cities like Honolulu and New York are among the most expensive for groceries due to transportation costs and high commercial rents. Midwest and Southeast cities tend to have the lowest grocery costs.

Dining out amplifies these differences further. A typical restaurant meal in San Francisco costs 40-60% more than the same meal in Nashville or Charlotte, driven by higher wages, rents, and ingredient costs.

Average monthly grocery spending per person ranges from about $250 in low-cost areas to $450+ in high-cost cities.

Transportation (10-15% of the Difference)

Transportation costs depend heavily on whether you own a car and your commute distance. Key factors include:

Healthcare (5-10% of the Difference)

Healthcare costs vary by region due to differences in insurance premiums, provider rates, and state regulations. The Northeast and West Coast tend to have higher healthcare costs than the Southeast and Midwest. However, if you have employer-sponsored insurance, your out-of-pocket costs may be similar regardless of location.

More relevant for most people is the cost of services not fully covered by insurance: dental work, vision, mental health, and prescription copays. These can vary significantly by metro area.

Utilities (3-5% of the Difference)

Monthly utility costs (electricity, gas, water, internet) range from about $150 in mild-climate, low-cost areas to $350+ in extreme-climate or high-cost areas. Hawaii has the highest electricity rates in the nation. Southern states have higher summer cooling costs while Northern states have higher winter heating costs.

How to Calculate an Equivalent Salary

The basic formula for an equivalent salary is:

Equivalent Salary = Current Salary x (New City COLI / Current City COLI)

For example, if you earn $80,000 in Dallas (COLI: 96) and want the same purchasing power in Seattle (COLI: 149):

Equivalent Salary = $80,000 x (149 / 96) = $124,167

This means you would need about $124,167 in Seattle to maintain the same standard of living as $80,000 in Dallas. Our Cost of Living Calculator does this math instantly for any pair of major US cities.

City-by-City Comparison Highlights

Here is how some major US cities compare for a worker earning the national median household income of approximately $80,000:

High-Cost Cities

Medium-Cost Cities

Low-Cost Cities

Remote Work and Geographic Arbitrage

Remote work has fundamentally changed the cost of living equation. If you can work from anywhere, you have the option to earn a high-market salary while living in a low-cost area โ€” a strategy called geographic arbitrage.

However, many companies are adjusting pay for remote workers based on location. The three most common approaches are:

Before relocating as a remote worker, clarify your employer's compensation policy and understand how a move would affect your pay. Even with a 10-15% pay cut, moving from San Francisco to Austin can result in significantly more disposable income.

Beyond the Numbers: Quality of Life

Cost of living calculations are important, but they do not capture everything that matters. Consider these qualitative factors when comparing cities:

A Step-by-Step Relocation Checklist

If you are considering a move, here is a practical checklist for comparing cities financially:

  1. Calculate equivalent salary: Use our Cost of Living Calculator to find the salary you need in the new city.
  2. Compare take-home pay: Use our Take-Home Pay Calculator with the new state to see actual net income.
  3. Research housing: Check rental listings or home prices in neighborhoods you would actually live in.
  4. Factor in commute costs: Will you need a car? How far is the office? What is parking like?
  5. Check property tax rates: If buying, property taxes can add thousands per year.
  6. Research sales tax: High sales tax states increase the cost of everyday purchases.
  7. Estimate utility costs: Climate extremes mean higher heating or cooling bills.
  8. Consider one-time moving costs: Moving expenses, security deposits, closing costs, and temporary housing can total $5,000-$20,000+.
  9. Build a monthly budget: Map out projected monthly expenses in the new city versus current expenses.
  10. Visit first: Spend a week in the new city before committing. Walk neighborhoods, check commute times, and eat at local restaurants to get a real feel for daily costs.

Common Mistakes When Comparing Cost of Living

Frequently Asked Questions

What is a cost of living index?

A cost of living index (COLI) is a number that compares the overall expense of living in one area to a baseline (usually the national average, set at 100). A city with a COLI of 120 is 20% more expensive than the national average, while a city at 85 is 15% cheaper. Indices typically factor in housing, groceries, utilities, transportation, healthcare, and miscellaneous goods and services.

What is the most expensive city to live in the US?

As of 2026, New York City (Manhattan) and San Francisco consistently rank as the most expensive US cities, primarily due to extremely high housing costs. Honolulu, San Jose, and Washington D.C. also rank in the top tier. However, the most expensive city for you depends on your specific lifestyle.

How much salary adjustment should I ask for when relocating?

A reasonable approach is to request a salary adjustment that matches the cost of living difference between your current city and your new city. For example, if you earn $80,000 in Dallas (COLI: 96) and relocate to Seattle (COLI: 149), you would need roughly $124,000 to maintain the same purchasing power. Use our Cost of Living Calculator to find the exact equivalent salary.

Does remote work eliminate cost of living differences?

Partially. If you work remotely from a low-cost city for a company based in a high-cost city, you can enjoy geographic arbitrage โ€” a higher salary with lower expenses. However, many companies are adjusting remote pay based on employee location. Clarify your employer's policy before relocating.

Should I consider state income tax when comparing salaries?

Absolutely. State income tax can make a 5-13% difference in your take-home pay. Moving from California (top rate 13.3%) to Texas (no state income tax) effectively gives you a significant raise even without a salary change. Use our Take-Home Pay Calculator to compare net pay across states.

What factors beyond salary should I consider when relocating?

Beyond salary and cost of living, consider: property tax rates, quality of public schools, commute times and transportation options, healthcare access and costs, weather and natural disaster risk, proximity to family and social network, career growth opportunities in the local job market, and overall quality of life factors like recreation, culture, and safety.
