01What a Regional Price Parity measures
A Regional Price Parity, or RPP, compares price levels across places in a reference year. The U.S. average is 100, so an all-items RPP of 112 means a metro's overall consumption price level is about 12% above the national level. It does not mean prices rose 12% that year, and it does not mean every product costs 12% more.
This calculator uses the 2024 all-items, goods, housing, utilities and other-services series from BEA table MARPP, released February 19, 2026. BEA combines detailed price information with Census rent data to estimate spatial price levels. The comparison is between metro areas, not between two neighborhoods or two specific homes.
RPP is a place-to-place price-level comparison. CPI is primarily a time-to-time inflation measure. They answer different questions.
02The default equivalent-salary formula
With no tax adjustment, equivalent salary equals current gross salary multiplied by the destination all-items RPP and divided by the current all-items RPP. Equal tax rates cancel out, so the same formula applies to after-tax purchasing power. A move from RPP 100 to RPP 140 needs 40% more salary; the reverse move needs 28.6% less, not 40% less.
This is a purchasing-power benchmark, not a prediction of what an employer will pay. Wages are set by role, experience, labor-market demand and company pay bands. Use the offer comparison to measure the gap between an actual offer and the estimate instead of treating the result as an automatic negotiation floor.
- Required salary = current salary × destination RPP ÷ current RPP.
- Gross salary difference = required salary − current salary.
- Current salary coverage = current salary ÷ required salary, capped at 100 for the assessment.
03Use your actual monthly budget
A single all-items ratio cannot know your rent, household size or spending mix. The personalization panel therefore accepts your current monthly spending in four published BEA categories. Each line is multiplied by its own destination-to-current category ratio. The calculator then preserves your current monthly dollar surplus, or explicitly carries forward a deficit, rather than pretending all income is spent.
The budget method is additive around your real spending. If your destination budget is $400 per month higher, you need $4,800 more annual after-tax income to keep the same dollar surplus. If you enter different effective tax rates, the calculator converts that after-tax need back to gross salary.
- Housing: tenant-rent price levels; owner housing is only approximated.
- Goods: durable and nondurable goods, including food, apparel and transportation goods.
- Utilities: water, sanitation, electricity and gas.
- Other services: transportation, medical, education, recreation, food services and other services.
04Taxes, childcare and job offers
There is no invented city tax index. BEA RPPs are not an income-tax calculator, and a metro can cross state lines. If you want a gross-salary estimate that includes taxes, enter your own effective income and payroll tax rates for the current and destination salaries. Zero percent leaves the tax adjustment off; equal rates leave the default RPP ratio unchanged.
Add childcare, education, insurance and other personal costs to the appropriate entered budget lines. Property tax, sales tax and similar household expenses should also be represented in actual spending rather than hidden in an unexplained tax weight. An optional job offer adds a direct offer-minus-required figure and coverage percentage to the results and exports.
05Why the source year is 2024
Official spatial statistics arrive after the reference year. BEA published these 2024 RPPs on February 19, 2026; the next scheduled release shown by BEA is December 10, 2026. The interface keeps the reference year and release date next to the inputs so an older observation cannot be mistaken for a live quote.
Do not inflate a city RPP with a national CPI series and call the result an official current index. That would mix a spatial price level with a time-series inflation measure and introduce an undocumented assumption. For a current lease, insurance premium or childcare place, collect real quotes and enter them in the personalized budget.
06What the comparison cannot decide
A metro average does not capture neighborhood safety, school fit, commute time, climate risk, healthcare access or proximity to family. It also cannot capture a fixed mortgage taken out years ago. The housing RPP is based on tenant rents, so homeowners should treat a housing-scaled estimate as approximate and use their real forward-looking housing costs.
The dataset covers U.S. metros plus the U.S. average and nonmetropolitan benchmark. It does not support an international city comparison or currency conversion. Lower prices do not automatically mean a better life, and higher prices do not automatically require a higher salary for every household.
