Cost of Living Calculator
Compare two cities using cost-of-living index numbers to find the equivalent salary you would need in the target city to maintain your current standard of living.
Understanding Cost of Living: How to Adjust Your Salary for a New City
When evaluating a job offer in another city or planning a relocation, one of the most important financial questions is: how much salary do I need to maintain my current standard of living? A $90,000 salary in Austin, Texas does not have the same purchasing power as $90,000 in San Francisco, California—or $90,000 in a smaller midwestern city. Cost-of-living indices provide a standardized way to compare the relative expense of living across different locations, allowing you to translate your current salary into an equivalent figure for any city you are considering.
What Is a Cost-of-Living Index?
A cost-of-living index (COLI) is a weighted average measure of the price level of consumer goods and services in a particular area relative to a reference point. The most common convention sets a baseline city or national average at 100. Cities with higher living costs score above 100, while more affordable locations score below 100. For example, if your current city has an index of 100 and you are considering moving to a city with an index of 130, that target city is approximately 30% more expensive overall.
The index typically incorporates housing costs, groceries, transportation, healthcare, utilities, and miscellaneous goods and services. The exact weighting varies by provider. Well-known publishers of cost-of-living data include Numbeo, Mercer's Cost of Living Survey, the Economic Intelligence Unit (EIU), and the Missouri Economic Research and Information Center (MERIC). Before comparing two cities, confirm that both index values come from the same provider and use the same reference baseline, as mixing indices from different sources can produce misleading results.
The Salary Adjustment Formula
The core calculation is straightforward: Equivalent Salary = Current Salary × (Target Index / Current Index). If you earn $75,000 in a city with an index of 100 and are considering a city with an index of 120, the equivalent salary would be $75,000 × (120 / 100) = $90,000. In other words, you would need $90,000 in the more expensive city to maintain the same purchasing power you enjoy today.
Conversely, if the target city has a lower index—say 80 compared to your current 100—the equivalent salary drops to $75,000 × (80 / 100) = $60,000. Moving to this cheaper city, you could accept a $15,000 salary reduction and still live at the same level. This bidirectional nature of the calculation makes it equally useful whether you are evaluating a promotion to a high-cost metro or considering a lifestyle move to a lower-cost region.
Using This Calculator
Enter your current annual salary along with the cost-of-living index for your current city. If you want to set your current city as the baseline, use 100. Then enter the index value for the target city. The calculator outputs the equivalent salary needed, the absolute salary difference in currency, and the percentage adjustment.
A positive percentage adjustment indicates that the target city is more expensive—you would need a higher salary there. A negative adjustment means the target city is more affordable—you could earn less and maintain the same lifestyle. These figures are useful both for negotiating compensation with a new employer and for deciding whether a particular salary offer is genuinely competitive given local living costs.
Limitations and Caveats
Cost-of-living indices provide useful approximations but have important limitations. First, the index is an average across many expense categories. Your personal cost profile may differ significantly depending on lifestyle. If you spend a disproportionate share of your income on housing, you should pay particular attention to housing-specific sub-indices rather than relying solely on the overall figure. If you rarely eat out or have a paid-off car, your true cost difference may be smaller than the composite index suggests.
Second, taxes are not captured in most cost-of-living indices. State income tax rates, property taxes, and local levies vary widely and can significantly affect take-home pay. A state with no income tax—such as Texas, Florida, or Washington—can be meaningfully more favorable than a similarly priced city in a high-tax state like California or New York. Factor in your effective tax rate when making relocation decisions, especially for large salary differences.
Third, lifestyle inflation is not accounted for. Moving to a city with a lower cost of living does not guarantee you will spend less; some people simply upgrade their spending to match the savings. Conversely, moving to an expensive city can force spending discipline. The calculator gives you a financial baseline; how you actually manage your budget is a separate decision.
Cost of Living vs. Cost of Labor
Employers in expensive metro areas often pay higher nominal salaries to attract talent, but those increases rarely keep pace with the full cost differential. Research consistently shows that high-cost cities tend to produce lower real (inflation-adjusted) wages after accounting for living expenses. Remote work and hybrid arrangements have disrupted this dynamic by allowing workers to live in lower-cost areas while earning salaries benchmarked to high-cost markets—a phenomenon that became especially pronounced after 2020.
When negotiating salary, knowing the cost-of-living equivalent gives you a concrete data point. If an employer in a city with an index of 130 offers you 15% more than your current salary, but the equivalent salary calculation suggests you need 30% more just to break even, that offer represents a real pay cut. Presenting this analysis professionally and factually can support a stronger negotiation outcome.
Practical Example
Consider someone earning $80,000 in Denver, Colorado (Numbeo index approximately 67 for a U.S.-relative scale, or use 100 as a self-referential baseline). A job offer arrives from a company in New York City, where the index is roughly 130 on the same scale. The equivalent salary calculation is $80,000 × (130 / 100) = $104,000. If the New York offer is $95,000, the candidate is effectively looking at a real-terms pay cut of approximately $9,000 per year despite the nominally higher salary.
Alternatively, if the same Denver resident receives a remote offer allowing them to remain in Denver while being paid at New York salary levels ($104,000), that represents a significant improvement in purchasing power—an effective 30% raise without changing lifestyle. These concrete comparisons, grounded in index data, cut through the ambiguity of nominal salary comparisons and let you evaluate opportunities on equal footing.
Frequently Asked Questions
What is a cost-of-living index and where do I get the numbers?
A cost-of-living index is a standardized measure comparing the overall price level in one location to a reference point (usually set to 100). Common sources include Numbeo, Mercer's Cost of Living Survey, the Economic Intelligence Unit, and the Missouri Economic Research and Information Center. Make sure both city values you enter come from the same source and use the same baseline.
Why should I set my current city index to 100?
Setting your current city to 100 is a convenience that makes the math intuitive—the target index then represents the percentage relationship directly. However, you can use any consistent index values from a single source. For example, if one source lists City A at 67 and City B at 88, you can enter those numbers directly without converting to a 100-based baseline.
Does the calculator account for taxes?
No. Cost-of-living indices reflect consumer prices, not tax burdens. State income taxes, local taxes, and property taxes are separate considerations. If you are comparing cities with significantly different tax environments—such as a no-income-tax state versus a high-income-tax state—factor in the effective tax difference separately when evaluating salary offers.
What does a negative salary difference mean?
A negative salary difference means the target city is less expensive than your current city. In that scenario, you could accept a lower nominal salary and still maintain the same purchasing power. For example, if the result shows a −$10,000 difference, you could earn $10,000 less in the target city and live at the same standard you enjoy today.
Can I use this for international comparisons?
Yes, but with caution. International cost-of-living indices are available from sources like Mercer and the EIU and can be used in the same formula. However, currency exchange rate fluctuations, purchasing power parity differences, and vastly different goods/services mixes make international comparisons less precise than domestic ones. For cross-border moves, treat the result as a rough directional estimate rather than a precise figure.
