Compare two locations using a transparent cost of living index and optional category weights. Instantly estimate an equivalent salary and monthly budget.
Most cost of living tools answer a simple question: if you move, how much would your income or budget need to change to keep a similar standard of living? The common building block is an index, where 100 typically represents a national average. If your current location index is 100 and your target is 120, the target is treated as about 20% more expensive overall.
Major publishers and calculators often rely on a city-to-city index like the C2ER Cost of Living Index, which is widely referenced for local comparisons. RentCafe and NerdWallet both state that their core cost of living data is from C2ER. Bankrate also discusses cost of living indexes and lists examples such as C2ER. If you have a trusted index value for your current and target locations, this calculator lets you apply it with transparent math.
In its simplest form, the calculation is a ratio: target index divided by current index. That ratio is applied to your salary to estimate an equivalent salary, and it can also be applied to a monthly spending estimate to project a target monthly budget. This approach is intentionally transparent. It does not hide assumptions in a black box. If you disagree with an index value, you can change it.
| Output | Formula | What it tells you |
|---|---|---|
| Equivalent salary | Current salary x (Target index / Current index) | Estimated salary needed to keep similar purchasing power |
| Target monthly budget | Current spending x (Target index / Current index) | Estimated monthly budget if your lifestyle stays similar |
| Index adjustment | Target index + adjustment | A stress test for lifestyle differences (housing choice, commute, etc.) |
They are most accurate when the index and the spending basket reflect your real life. Two people in the same city can have very different budgets because housing choices, commuting style, and family size change the spending mix. This is why advanced tools often break costs into categories and why some calculators mention that housing is typically the largest monthly expense category.
If you want a more personalized estimate, the advanced mode lets you weight categories so the model reflects how you spend money. The guardrails are intentional: if inputs are invalid (like an index of zero) the calculator shows a warning instead of producing misleading results.
Location comparisons and inflation over time are different questions. A location comparison is about price level differences across places. Inflation is about how prices change over time. For inflation, the Bureau of Labor Statistics explains that the Consumer Price Index (CPI) measures average price changes over time for a basket of goods and services. BLS also provides a CPI inflation calculator based on CPI-U (U.S. city average). If your question is "how much did prices rise since 2021", inflation tools like CPI are designed for that.
If you want an official U.S. government concept for comparing price levels across states and metro areas, the Bureau of Economic Analysis publishes Regional Price Parities (RPPs). BEA states that RPPs measure differences in price levels across states and metro areas for a given year and are expressed as a percentage of the overall national price level (100). This page includes a few verified example presets from BEA 2024 to show how the index concept works.
Most cost of living comparisons start with an index that summarizes local prices across major categories like housing, groceries, utilities, transportation, and healthcare. A common convention uses 100 as a baseline (often the U.S. average). If your target index is 120 and your current index is 100, the target is treated as about 20% higher overall.
They are most useful as planning tools, not exact predictions. Results depend on the underlying data source and on whether the "average basket" matches your real spending. Housing is often the biggest reason two people in the same city can have very different budgets. If you rent a smaller place or work remotely, your personal costs may differ a lot from a standard index.
Many well known city to city calculators use C2ER cost of living index data (a widely referenced U.S. local index). Some "official" government measures exist too. For example, BEA Regional Price Parities (RPPs) compare price levels across states and metro areas as a percentage of the national price level. Choose the source that matches your goal and the geography you need.
Usually no. Taxes depend on filing status, deductions, and local rules. Two households with the same income can have different after tax outcomes in the same state. Use the calculator to estimate purchasing power, then compare after tax pay separately if taxes are a major part of your decision.
A simple approach is to estimate the percent difference between locations and apply it to pay or to your budget. For example, if the target is estimated to be 15% higher overall, an allowance might be built around closing some or all of that gap. Employers often adjust differently for housing versus other costs, so a category weighted model can be more realistic than a single number.
That is a different question from comparing two places. "Increase over time" is inflation. The Consumer Price Index (CPI) is a commonly used measure of average price changes over time for a basket of goods and services. If your goal is to update a past budget to today's dollars, an inflation measure is more appropriate than a city comparison index.
Start with your real monthly expenses, especially housing, transportation, and health insurance. Then use a location index ratio to scale your budget. If your spending mix is not average, use category weights so the estimate reflects your lifestyle (for example, higher housing weight if you spend a large share on rent).
