Is Joliet Affordable?

Is Joliet affordable? It's a key consideration when pondering a move, as affordability often shapes your choices. The cost of living index (we discussed it earlier), coupled with housing costs and income levels, serves as the cornerstone for determining a location's affordability. Take Joliet, for instance, where the median home price falls 7.4% higher than the national average, and monthly rent rates are 11.7% higher than usual. Additionally, median income levels contribute to the equation, with Joliet flaunting a median household income of $110,204, 35.5% higher than the national norm.

What Factors can Influence the Cost of Living in Joliet?

Taxes: Cities that enforce higher taxes, covering both sales taxes and income taxes, can be a factor contributing to a higher cost of living. Paying more in taxes for everyday essentials like clothing and food inevitably leads to higher expenses. A higher income tax rate can further contribute to an overall elevated cost of living. In Joliet, the baseline sales tax rate begins at 6.25%, and income tax rates start at 4.95%.

Healthcare: The costs associated with healthcare and insurance premiums can exhibit notable disparities based on the city or state of residence. Access to healthcare facilities, out-of-pocket expenses for medical appointments, dental care charges, prescription medication costs and specialized medical care expenses all contribute to variations in the cost of living. In Joliet, healthcare costs are 5.8% higher than the national average.

Transportation: If public transportation is limited or not available, residents may need to own and maintain vehicles, which can add to the cost of living. Gas, insurance, regular maintenance and potentially lease or finance payments will all need to be paid on a monthly basis. In Joliet, the transportation index is 0.2% higher than the national average.

Where is the Data From?

The cost of living in Joliet, presented above is derived from the C2ER cost of living index, offering a practical method for assessing living cost disparities in urban areas. Published quarterly, this index compiles data from more than 300 independent researchers, encompassing over 60 goods and services in 6 categories.
