What This Comparison Actually Tells You
The Bureau of Economic Analysis indexes Boulder, CO at an overall Regional Price Parity of 105.2 and Philadelphia-Camden-Wilmington, PA-NJ-DE-MD at 102.6, using the U.S. national average of 100 as the reference point. That puts Philadelphia-Camden-Wilmington 2.5% less expensive than Boulder on a blended basket of goods, services, and rents. The raw index gap of 2.6 points matters more than the headline comparison because it flows directly into salary-equivalent math that families use for relocation, job offers, and remote-work arbitrage decisions.
Inside the breakdown, Boulder indexes goods at 96.1, services at 82.7, and rents at 157.0, while Philadelphia-Camden-Wilmington comes in at 96.8, 114.4, and 113.1 on the same three categories. The rent line carries the largest weight in the BEA methodology, so a metro with a higher rent index almost always ends up more expensive overall - Boulder carries the heavier rent load here, and that tends to dominate household budget experience on the ground.
In salary terms, a $100,000 income in Boulder has the same purchasing power as $97,483 in Philadelphia-Camden-Wilmington based on these indexes. The two metros serve populations of roughly 328,317 (Boulder) and 6,241,882 (Philadelphia-Camden-Wilmington), and median household incomes are $102,772 versus $89,273 respectively - so the right way to read this comparison is never the index alone, but the ratio of your expected local salary to the rent and services mix. For any serious relocation or remote-work decision, pair this BEA comparison with BLS occupation-specific wage data, HUD Fair Market Rent tables, and state tax treatment before committing.
