Compare purchasing power between two locations using cost-of-living index values. Estimate an equivalent gross salary and monthly spending level, then stress-test the result with your own assumptions.
The calculator estimates how much gross income or monthly spending would have to change if the price level in one location differs from another. The core calculation is intentionally transparent: it uses the ratio between a target cost-of-living index and a current index.
If your current index is 100 and the target index is 110, the simple model treats the target as 10% more expensive overall. A $70,000 gross salary would therefore scale to an estimated $77,000 for similar overall purchasing power before taxes, benefits and lifestyle differences.
For official U.S. geographic price-level comparisons, the Bureau of Economic Analysis publishes Regional Price Parities (RPPs). BEA defines RPPs as differences in price levels across states and metropolitan areas for a given year, expressed as a percentage of the overall national price level. A value of 100 represents the national level.
The built-in presets use BEA 2024 state-level RPP values released in February 2026. Examples include California 110.7, Hawaii 110.0, New Jersey 108.8, the District of Columbia 109.9, Arkansas 86.9 and Mississippi 87.0.
For a metro-based comparison without manually entering index values, a separate cost of living calculator lets you select U.S. locations and estimate equivalent gross income using 2024 BEA RPP data.
The quality of the result depends on the quality and consistency of the indexes you enter. Use values from the same source, year and methodology whenever possible. Comparing a state-level government index with a city-level commercial index can produce a number that looks precise but is not methodologically consistent.
The optional adjustment lets you stress-test a location without pretending the official index is wrong. For example, you might add points if the housing you would realistically choose is more expensive than the area average, or subtract points if your expected lifestyle is materially cheaper.
The adjustment is a planning assumption, not a data correction. Keep it modest and run several scenarios rather than treating a single adjusted result as exact.
The advanced mode is a user-defined sensitivity model. It is not an official BEA methodology. You choose how much of your spending belongs to housing, food, transportation, utilities, healthcare and other costs; the weights must total 100%.
The overall location ratio is used as the base change. The housing and “other” sensitivity multipliers let those two broad categories move more or less than the base ratio. This can be useful for scenario planning when housing dominates your budget, but it should not be interpreted as a measured category-level price index.
A cost-of-living ratio adjusts purchasing power, not compensation strategy. Two jobs with the same "equivalent" gross salary can still produce different outcomes because of federal and state taxes, health-insurance premiums, retirement contributions, bonuses, stock compensation, commuting costs and employer benefits.
For a relocation or job offer, compare at least four layers separately:
Cost of living across locations and inflation over time answer different questions. A location index compares price levels between places. Inflation measures how prices change over time.
For U.S. inflation over time, the Bureau of Labor Statistics publishes the Consumer Price Index and an official CPI Inflation Calculator. The BLS calculator uses CPI-U data for the U.S. city average. Use an inflation measure when the question is “what is a past dollar amount worth today?” rather than “how expensive is one location compared with another?”
It usually represents the baseline used by that index. For BEA Regional Price Parities, 100 is the overall national price level. A value above 100 indicates a higher price level than the national level for that year; a value below 100 indicates a lower one.
Usually not. Different providers can use different baskets, geographic definitions, weights and time periods. Use both locations from the same source and release whenever possible.
No. It scales gross salary and spending by a price-level ratio. Federal, state and local taxes depend on filing status, deductions, credits and other factors, so they should be analyzed separately.
Yes, but only as one planning input, not as a final compensation target. A defensible job-offer comparison should also include market pay for the role, taxes, benefits, housing, commute costs and any relocation package.
Use an inflation measure rather than a location-comparison index. For U.S. consumer inflation, BLS CPI data and the BLS Inflation Calculator are appropriate starting points.
