Most affordable ZIP codes in Illinois
Ranked by the SkaldMaps Cost of Living Index, lowest first. 100 is about the national level; lower values indicate lower estimated costs.
How we rank lowest cost of living
The Cost of Living Index combines the local cost of everyday goods and services with the estimated cost of owning a typical listed home, including mortgage payments, property taxes, insurance, and maintenance. These measures are combined and compared with a national baseline.
100 is about the national level. Below 100, a homebuyer's money goes further; above 100, it goes less far.
It reflects homes for sale today, not what current owners pay, so it needs listing data: ZIPs without enough listings are not ranked. It does not include income, so a low index does not mean local wages cover local costs.
Only ZIPs with at least 1,000 residents are ranked, so a handful of households cannot top the list. 756 Illinois ZIPs qualify.
