Regional pricing methodology

How the estimate is calculated

The calculator first determines the material quantity. It multiplies that quantity by a broad U.S. planning range for the material, then applies the selected state’s goods-price adjustment. The displayed “typical” amount is the midpoint of the adjusted range.

Regional factors use the U.S. Bureau of Economic Analysis 2023 Regional Price Parities for goods, where the U.S. average equals 100. These indexes measure broad regional price differences; they are not a record of a particular retailer’s inventory.

Location and privacy

On Cloudflare, the site receives an approximate city and state associated with the request. CalcCaddy returns only those broad fields to the page; it does not return or store the visitor’s IP address. Visitors can change the state or choose the U.S. average. A manual selection is stored only in that browser.

What is excluded

Ranges exclude sales tax, delivery, labor, contractor overhead, minimum orders, permits, site conditions, product grade, brand, seasonal shortages, and store-specific promotions. Always replace the planning estimate with supplier quotes before purchasing.

Sources and update policy

Regional adjustment source: U.S. Bureau of Economic Analysis Regional Price Parities. Baseline material ranges are editorial planning assumptions reviewed periodically and intentionally shown as ranges. The next pricing phase will separate labor and add more granular market data where defensible sources are available.
