Price levels use the U.S. Bureau of Economic Analysis Regional Price Parities for metropolitan areas (2023, the most recent metro-level release). Boise maps to the Boise City, ID MSA; Seattle maps to the Seattle-Tacoma-Bellevue, WA MSA. Category spending baselines come from the U.S. Bureau of Labor Statistics Consumer Expenditure Survey. Category-level figures are modeled estimates and are illustrative; actual costs vary by household. This is a planning tool, not financial advice.
