Cost of Living Index

A composite index where 100 equals the national average, measuring relative expenses across housing, groceries, utilities, transportation, and healthcare.

The Cost of Living Index compares overall expenses in a city to the national average (100). A value of 110 means the city is 10% more expensive than average; 90 means 10% less expensive.

WhereAtHome uses cost-of-living data as an adjustment factor in the Purchasing Power scoring component. When available, it adjusts the income-based score to account for local purchasing power. When unavailable for a city, the adjustment is omitted (disclosed in the methodology).
