How This Calculator Works
Calculation methodology and assumptions
Renovation cost estimates for Illinois scale a national baseline of $150 per square foot (standard-quality kitchen) by Illinois's cost-of-living index of 94.5 (C2ER Cost of Living Index, Q2 2026; 100 = national average). The index measures overall living costs in surveyed urban areas, not contractor wages, so it is a rough local price adjustment. Illinois's index is near the national average. Cost split: 40% materials, 50% labor, 2% permits, 10% contingency.
Key State Information
Illinois renovation estimates run near the national baseline. Cost-of-living index (C2ER, Q2 2026): 94.5/100. A standard kitchen remodel in Illinois costs approximately $28,350 for 200 sq ft. Median home value: $299,000.
Example Calculation
A 200 sq ft standard kitchen remodel in Illinois, priced with this page's defaults.
The national baseline of $150 per sq ft times Illinois's cost-of-living index of 94.5 (C2ER, Q2 2026) gives $141.75 per sq ft, or $28,350 for 200 sq ft. That base splits into materials $11,340 (40%), labor $14,175 (50%) and permits $567 (2%); those three lines cover 92% of the base, and the calculator does not itemize the other $2,268. A 10% contingency of $2,835 brings it to $31,185.
Result: $31,185 with contingency, 10.4% of Illinois's $299,000 median home value (Zillow ZHVI, June 2026). If you buy the $11,340 of materials yourself, Illinois's 6.25% state sales tax adds about $709, or up to $1,247 where the maximum 4.75% local rate also applies. The calculator does not add sales tax as a separate line.
The Illinois figures behind this estimate
Illinois's cost-of-living index is 94.5, the 24th-lowest of the 50 states in the C2ER Q2 2026 release. This page multiplies its national baselines by that index, so every Illinois estimate here is 5.5% below the national figure for the same project. The index tracks overall living costs in surveyed urban areas, not contractor wages, so treat it as a rough local price adjustment and compare written bids.
| Figure | Illinois | Effect on a remodel |
|---|---|---|
| Cost-of-living index (C2ER, Q2 2026) | 94.5 | $141.75 per sq ft on this page's model |
| Median home value (Zillow ZHVI, June 2026) | $299,000 | the $31,185 estimate is 10.4% of it |
| Sales tax on materials bought at retail | 6.25% state + up to 4.75% local | about $709-$1,247 on $11,340 of materials |
| Effective property-tax rate (ACS 2024) | 1.88% | about $188 a year for each $10,000 a remodel adds to the assessed value |
Property tax only rises if Illinois's assessor raises the assessed value after the work, and assessment rules and caps differ by state and county. Sales tax applies to materials you buy yourself; when a contractor supplies them, how the tax is charged depends on Illinois's contractor rules.

Are contractors expensive in Illinois?
This calculator has no contractor wage data for Illinois.

How much sales tax will I pay on remodel materials in Illinois?

Will a remodel raise my property tax in Illinois?
Only if the assessor raises your home's assessed value. At Illinois's 1.88% effective property-tax rate (Census ACS 2024), each $10,000 of added assessed value costs about $188 a year. Check your county assessor's rules on when improvements are reassessed.
