How Illinois's cost of living compares nationally
At 95.1, Illinois is 4.9 points below the US average of 100. Housing is 84.7, while groceries are 99.2.
Is Illinois an affordable state to live in?
Illinois's 95.1 composite is close to the US average of 100, although individual category and local-market costs can still differ. Affordability ultimately depends on household income, after-tax pay, housing choice, debt, and required services—not the index alone.
Household planning
What Illinois's cost of living can mean for your household
The 95.1 composite is a useful starting point, but households experience Illinois prices differently based on housing, family size, work location, and ownership.
Renters
Compare neighborhood rent and utilities with the 84.7 housing index; statewide averages can hide large metro differences.
Homeowners
Add mortgage costs, property taxes, homeowners insurance, maintenance, and post-purchase assessments.
Families
Groceries benchmark at 99.2, but childcare, healthcare, and the size of the home may matter more.
Remote workers
Confirm whether pay changes by work location, then compare state taxes, workspace costs, and travel needs.
How to build a realistic Illinois moving budget
Use the index to screen destinations, then replace broad averages with prices tied to the address and household you are considering.
1. Adjust salary
Apply the 95.1 index, then calculate after-tax pay at the expected salary.
2. Price housing
Use current local listings and include deposits, utilities, insurance, parking, and commute.
3. Add household needs
Estimate childcare, healthcare, groceries, vehicles, debt payments, and recurring services.
4. Stress-test the move
Include moving costs, emergency savings, job risk, and room for prices or insurance to increase.
Why costs vary within Illinois
Metro and neighborhood differences
Employment centers, housing supply, commute access, schools, and local amenities can create large price gaps between communities even when they share the same statewide index.
Household-specific differences
Renters, homeowners, families, retirees, and commuters buy different combinations of housing, transportation, healthcare, utilities, and services, so their effective cost changes will differ.
Calculation details
How Illinois's 95.1 index is determined
MERIC averages C2ER Cost of Living Index results for participating urban areas in Illinois. The result is a statewide comparison benchmark for Q1 2026, not an exact city or household budget.

Questions to ask before moving to Illinois
What salary in Illinois matches my current purchasing power?
How do local rents or home prices compare with the statewide housing index?
What is after-tax pay at my expected salary and filing status?
How do insurance, healthcare, childcare, and utilities compare?
Does the local job market support the equivalent salary I need?
Do wages, services, and lifestyle outweigh the cost difference?
Employment decisions
How to evaluate a job offer in Illinois
A salary can look higher while buying less after local prices and taxes. Compare the complete offer rather than applying the cost-of-living ratio to base pay alone.
Purchasing-power salary
Use Illinois's 95.1 index to estimate the gross salary needed for a comparable market basket.
After-tax paycheck
Calculate federal, state, local, and payroll taxes at the actual filing status and compensation.
Benefits and work costs
Compare health premiums, retirement match, paid leave, commuting, parking, and remote-work support.
Housing and moving costs
Price a realistic neighborhood and include deposits, closing costs, movers, travel, and temporary housing.
Costs the Illinois index does not fully capture
The C2ER market basket standardizes consumer-price comparisons, but several major household decisions require separate research.
Taxes and government charges
Income tax, property tax, tax credits, vehicle registration, and address-specific local taxes vary by household.
Insurance and care needs
Home, auto, health, flood, and wind insurance—as well as childcare and long-term care—can vary sharply.
Debt, savings, and lifestyle
Student loans, retirement goals, travel, private school, hobbies, and family support are personal budget items.
Why this is not a personal Illinois budget
The statewide index averages participating urban areas and a standard market basket. Your neighborhood, housing size, commute, family needs, and spending mix can produce a very different result. Pair the index with local listings and tax tools before making a move decision.
