Chicago doesn't get the hype tax of the coasts. It still takes a real cut of your paycheck — and then quietly reminds you about sales tax and winter heating.
$100,000 in Chicago for 2026 — Illinois uses a flat state income tax on taxable income as modeled for 2026. There’s no separate city wage income tax like NYC on this baseline — so Chicago compares cleanly: federal + Illinois flat + FICA.

Why Chicago Feels Different at $100k
Our relocation calculator assigns Chicago a 100 cost-of-living index — national baseline. Combined with higher take-home than NYC or California at the same $100k gross, the same salary buys more city here than on the coasts.
Rent: One-bedroom citywide has been ~$1,900–$2,200 in many 2025–2026 reads; premium neighborhoods (Lincoln Park, Wicker Park) run higher; Uptown, Rogers Park, Bridgeport can land $1,400–$1,700. Our Chicago comfortable guide has the neighborhood breakdown.
Transit: The CTA is real — a monthly unlimited Ventra pass is $105. Many professionals get by $150–$350/month total depending on whether they keep a car for weekends.
Groceries: Near national average, maybe 3–5% above — $350–$500/month cooking at home. Restaurant scene punches above its price vs. NYC/SF.
Utilities: Winter heating hurts — $150–$250 in cold months; annual average often $150–$200 blended. Internet $60–$90.
Sales tax: Combined 10.25% in Chicago — same headline rate as Seattle, different mechanism. It nibbles on every purchase; it adds up on $2,500–$3,500/month spending.
Illinois income tax: 4.95% flat — predictable. At $100k, $4,950 state liability in our table.
~$6,186 Net vs. Fixed Costs (Sketch)
Example middle path:
| Item | Rough monthly |
|---|---|
| Rent (1BR, decent neighborhood) | $1,900–$2,300 |
| Groceries | $400–$500 |
| Utilities + internet | $200–$280 |
| Transit (no daily car) | $105–$250 |
| Health (employer share) | $150–$350 |
At $2,000 rent and mid-range other lines, you can still have $1,500–$2,000+ left for savings, travel, and life before car payments — that’s why $100k “reads” better here than in SF or NYC.
Life Stages
Roommate: Two-bedroom splits $1,200–$1,750 per person in many neighborhoods — $100k is very comfortable with a roommate by our Chicago guide standards.
Solo: Our comfortable baseline for Chicago is ~$100k gross — you’re right on the “comfortable solo, save meaningfully” story if rent isn’t extravagant.
Buying: Metro median purchase ~$375k–$385k; principal + interest ~$1,900–$1,950 at illustrative rates — then Cook County property taxes often $650–$780/month on top. All-in $2,700–$2,900 housing is reachable on $100k in a way it simply isn’t in SF or NYC; our guide still likes $110k–$130k for comfortable ownership slack.
Kids: Childcare $1,600–$2,400/month; family of four $170k–$200k household in the comfortable framework.

Who this is for
Finance, consulting, healthcare, logistics — anyone who wants big-city life without coastal rent and who’s tired of friends in NYC saying “we make the same salary” when net and rent say otherwise.
What changes your real check vs. our table
- 401(k), HSA: Reduce taxable income — rerun the Illinois calculator.
- Married filing jointly: Brackets change at federal level; state is still flat on taxable income in Illinois’s structure.
- Bonuses: May withhold at supplemental rates — annual true-up matters.
- Property taxes if you buy: Cook County can shock first-time buyers — our Chicago comfortable salary spells out ~$650–$780/month tax portions on typical purchases.
Mistakes when budgeting Chicago on $100k
1. Ignoring 10.25% sales tax. It hits daily spending; it’s not income tax but it matters to “where did my money go?”
2. Assuming “flat tax” means small tax. 4.95% of $100k is $4,950 — it’s in the table for a reason.
3. Forgetting winter utility spikes. Heat is a real line item November–March.
4. Comparing only gross salary to coastal friends. Chicago take-home on $100k beats NYC and California in our engine and rent is lower — that’s the double advantage.
