According to the U.S. Bureau of Economic Analysis's latest Regional Price Parity data, San Francisco-Oakland-Fremont, CA carries an RPP of 115.6, the highest of any metro on record, against Monroe, LA's 83.6, the lowest — a 1.38× gap in purchasing power. Both calculators below apply this same BEA index to whichever pair of metros you enter; see our methodology for the exact formula.

Every figure on PlainCost is rendered directly from BEA Regional Price Parity source data, no number is typed in by an editor. Both calculators run the same purchasing-power formula used throughout the site, applied live to whichever metros you choose. See our editorial standards & corrections policy, the methodology behind these numbers, our changelog, or report a data error. Rankings measure the published cost-of-living index only; we don't recommend where to live or rate any metro's quality of life.
