Salary vs. Cost of Living

Why Nominal Salary Comparisons Mislead

When comparing job offers in different cities, the nominal salary on the offer letter is only the starting point. BEA's all-items RPP measures the average price level for consumption goods and services, including housing rents, in each metro relative to the national level.

To put two salaries on the same national-price basis, divide each salary by its metro RPP divided by 100. This is a price-level adjustment, not a prediction of your household budget: actual housing, taxes, commuting, and benefits still need separate checks.

WageDex's metro salary data provides the occupation-wage side of the comparison. Pair it with the latest available RPP for the same metro, and note each series' reference year.

Purchasing Power of $100,000 Across Metros

The table applies BEA's published adjustment: current-dollar income divided by RPP/100. It shows the national-price purchasing-power equivalent of the same $100,000 salary in the five highest-RPP metros and the lowest-RPP metro in the current WageDex dataset.

Check Housing Separately

BEA's all-items RPP includes housing rents as part of the consumption basket, and BEA also publishes a separate housing-rents RPP. Neither index tells you what a particular apartment or home will cost.

Your own housing choice can differ substantially from the metro average. Compare current listings for the location, unit type, and tenure you would actually choose instead of applying a universal housing percentage.

When comparing cities, look at housing costs separately from general cost of living. If you plan to rent, focus on median monthly rent for your target unit type. If you plan to buy, compare median home prices and 30-year mortgage payments at current rates in each market.

Calculate Taxes Outside the RPP

Regional Price Parities compare consumer price levels; they do not convert gross salary to take-home pay. Tax liability depends on filing status, deductions, credits, locality, and the current law in each jurisdiction.

For an offer comparison, estimate federal, state, and local taxes from the same gross-pay assumptions using current official guidance. Keep that calculation separate from the RPP adjustment so a price-level index is not mistaken for an after-tax estimate.

How to Compare Two Job Offers Across Cities

A practical step-by-step process for evaluating offers in different metros:

1. Look up both occupations on WageDex. Use the metro-level wage data to place each offer against the published local wage distribution.
2. Find the cost-of-living index for each city. Use BEA RPP data and note the housing-rents sub-index separately if housing drives the decision.
3. Calculate the purchasing-power-equivalent salary. Divide each salary by the city's cost index and multiply by 100. Compare the results.
4. Calculate after-tax take-home pay. Use current official federal, state, and local guidance with the same filing assumptions for both offers.
5. Estimate monthly housing cost. Look up median rent or mortgage payment for your target unit type in each city. Confirm housing is affordable on after-tax take-home in both scenarios.
6. Factor in the job itself. Compare responsibilities, benefits, schedule, commute, advancement terms, and any location-based pay policy. RPP does not measure these parts of an offer.

Geographic Arbitrage: The Remote Work Opportunity

A remote offer can separate the employer's location from the worker's price level, but the result depends on the written pay policy. Ask whether compensation changes when the work location changes.

Once the actual offer is known, apply the RPP for the place where you would live. Then compare taxes, housing, benefits, and any required travel separately. The index alone cannot establish the value of remote work.
