How we price this for Philadelphia
We take each national base range and multiply it by Philadelphia's local index of 1.04:
local range = national base × 1.04
The index blends the metro's wage relativity (Philadelphia metro wages for appliance technicians (BLS OEWS occupation 49-9031)) with the BEA Regional Price Parity for Philadelphia, held to a sane band. Parts ship at national prices, so only the labor and overhead share moves with the metro. These localized estimates are cross-checked against 3 locally published service fees in the observed stat above — figures we show verbatim, never run through the index. The full method and source vintages are on the methodology page.
