How to Compare Cost of Living Between Cities (2026)
By Rui Barreira · Last updated: 18 June 2026
Moving to a new city — or evaluating a remote job offer — requires more than comparing salaries. A $90,000 salary in Austin and a $90,000 salary in San Francisco are not equivalent once you account for rent, groceries, taxes, and transport. Cost of living indices let you normalize those differences so you can make a like-for-like comparison. Use the Cost of Living Index to run the numbers instantly without registration or uploads.
What Cost of Living Indices Measure
A cost of living index expresses the relative price level of a city against a baseline — typically a national average (100) or a specific reference city. A score of 130 means living there costs 30% more than the baseline; a score of 85 means 15% cheaper. Most indices break the overall score into components so you can see where the gap actually lives:
| Component | Typical weight | Why it matters |
|---|---|---|
| Housing | ~30–40% | The largest single driver of city-to-city differences |
| Groceries | ~10–15% | Varies less than housing, but adds up over a year |
| Transportation | ~10–15% | Car ownership vs. transit access changes this dramatically |
| Healthcare | ~10% | Relevant if you are self-employed or uninsured |
| Utilities & misc. | ~20–30% | Energy costs vary by climate and grid |
How to Compare Two Cities Accurately
Start by anchoring on your current city as the baseline. Enter your current income, then enter the target city. The tool calculates the equivalent salary you would need in the new city to maintain the same purchasing power. A common mistake is comparing median rent alone — that misses grocery costs, state income tax, and transit. The equivalent-salary figure accounts for all components weighted together.
Tax treatment matters too. States like Texas and Florida have no income tax, which can offset a higher cost of living by several percentage points. Compare take-home pay, not gross salary, when evaluating a job offer across state lines.
Practical Decisions This Comparison Supports
Cost of living comparisons are most useful in three scenarios. First, evaluating a relocation: if a new employer offers a 15% raise but the destination city is 25% more expensive, the offer is effectively a pay cut. Second, negotiating remote work: if you are moving away from an expensive hub while keeping the same role, the index gives you a data-backed anchor for a salary conversation. Third, retirement planning: a lower cost of living city can extend a fixed income significantly — a portfolio that supports 20 years in Boston may support 30 years in Tucson.
Use the Cost of Living Index to compare any two cities and calculate the salary equivalent in seconds.
