The Denver cost of living vs Chicago question doesn’t have a one-word answer: Denver is cheaper on taxes, gas, and day-to-day expenses, but buying or renting a home costs noticeably more here, so housing decides the comparison for most movers.
If you’re weighing a move from Chicago to Denver, “is it cheaper?” is usually the first question and the hardest to pin down. The honest answer depends almost entirely on housing. Chicago is one of the more affordable big-city housing markets in the country, while Denver has spent a decade as one of the more expensive. On paper that makes Denver look pricier, but housing is only part of the math.
Factor in Colorado’s low property taxes, lower income tax, much lower sales tax, and cheaper gas and utilities, and the gap narrows — in some categories it flips. Many transplants find the sticker shock of a Denver home price is partly offset by everything that follows it: the annual tax bill, the utility statement, and the pump.
Below is a category-by-category comparison built on current public data — Census figures for housing and income, Tax Foundation figures for taxes, and state gas prices — so you can see where Denver saves you money and where it costs you more. Run your own numbers for your income and household before you commit.
- Buying a home: far more expensive in Denver — median value about $616,000 vs about $334,100 in Chicago (Census).
- Renting: higher in Denver — median gross rent about $1,831 vs about $1,440 in Chicago (Census).
- Income tax: lower in Colorado — a flat 4.40% vs Illinois’s flat 4.95% (Tax Foundation).
- Property tax: much lower in Colorado — about 0.50% effective vs 1.88% in Illinois (Tax Foundation).
- Sales tax: lower base in Colorado — 2.90% state vs 6.25% in Illinois; combined averages 7.89% vs 8.96%.
- Gas: a bit cheaper in Colorado — about $4.07 vs $4.32 per gallon (Aug 2026).
- Incomes: higher in Denver — median household income ~$94,718 vs ~$77,902 (Census).
Housing: where Chicago wins on price
Housing is the biggest line item in any relocation budget, and it’s where Chicago has a clear edge. Per U.S. Census QuickFacts, the median value of an owner-occupied home in the city of Denver is roughly $616,000, versus about $334,100 in Chicago — close to double. Rent tells a similar story: median gross rent is about $1,831 in Denver against roughly $1,440 in Chicago.
That gap is real, but the comparison is more nuanced than the headline number. Chicago’s low median partly reflects a huge, varied housing stock at very different price points, which pulls the citywide median down; Denver’s smaller, tighter market and steady in-migration have kept prices firm. If you’re coming from a pricey North Side neighborhood, the jump to a comparable west-Denver area like Berkeley, Sloan’s Lake, or Applewood may feel smaller than the medians suggest; from an affordable outer neighborhood, Denver will feel expensive. Either way, model your actual range — the FORM affordability calculator shows what your Chicago budget buys here.
Taxes: where Colorado wins
Taxes are where the Chicago-to-Denver move usually pays you back. Colorado charges a flat 4.40% state income tax; Illinois charges a flat 4.95%, per the Tax Foundation. That difference adds up on a six-figure income, but it’s modest next to property tax: Colorado’s effective property tax rate is about 0.50% of home value — one of the lowest in the country — while Illinois sits near 1.88%, among the highest.
That spread matters more than the home-price gap for many buyers. A $600,000 Denver home taxed near 0.50% carries a very different annual bill than a $334,000 Chicago home at 1.88% — the two can land closer than you’d expect, sometimes with Denver lower despite the price. Sales tax leans Colorado’s way too: the state base is 2.90% versus Illinois’s 6.25%, and combined state-and-local averages run about 7.89% here against 8.96% in Illinois, though Denver’s local add-ons push its own rate higher. It mirrors what we found comparing Denver and Dallas: different states win different rounds.
Getting around: transit vs. the car
Transportation is the category where Chicago quietly saves money — if you use it right. The CTA’s “L” and bus network is one of the most extensive in the country, and plenty of Chicagoans live car-free, cutting out car payments, insurance, gas, and parking entirely. Denver’s RTD covers light rail and buses and is useful for downtown commutes and airport trips, but coverage is thinner and the metro is more spread out. Most Denver households keep a car, and many keep two.
That car dependence is a real cost to budget for. On the flip side, Colorado gas is a touch cheaper — about $4.07 per gallon versus $4.32 in Illinois as of August 2026 — and Denver parking is easier than Chicago’s downtown crush. If you’re leaving a car-free Chicago lifestyle, expect to add vehicle costs; if you already drove, this category is close to a wash.
Utilities, energy, and weather
Weather drives utility costs, and the two cities differ in useful ways. Chicago winters are longer, damper, and colder for more of the year, which means higher heating demand. Denver is high desert: winters are cold but sunny and dry, cold snaps break fast, and abundant sunshine keeps heating loads down, while low-humidity summers make air conditioning work less hard than through a muggy Chicago July. The net effect is a slightly gentler year-round utility profile in Denver. The exception is water — Colorado is arid, outdoor watering is regulated, and summer bills for a yard can surprise newcomers — so budget utilities as roughly comparable, with Denver’s heating edge offset somewhat by water in the growing season.
Everyday costs: groceries, gas, and the rest
Day-to-day spending tends to favor Denver at the margins. Gas is cheaper, the lower base sales tax helps on retail purchases, and groceries and general services run broadly similar between the two metros. Denver’s lower tax drag means a paycheck stretches a little further on routine spending — before housing. Incomes help too: Denver’s median household income is about $94,718 versus roughly $77,902 in Chicago, cushioning the higher home prices. Some transplants keep remote roles at Chicago pay and come out clearly ahead; others take a local salary and find the housing math tighter.
Who comes out ahead
There’s no universal winner — it comes down to how you weight housing against everything else. Chicago wins if you’re a renter or a car-free urbanist who values a cheaper home market and world-class transit and will pay Illinois’s high property and sales taxes for it. Denver wins if you’re a buyer who plans to stay a while, values low property and income taxes and sunnier weather, and can absorb a higher purchase price knowing the annual carrying costs are lighter — those lower ongoing taxes and cheaper energy often narrow, and sometimes erase, the monthly gap the sticker price implies.
Frequently Asked Questions
Is Denver cheaper than Chicago overall?
Not uniformly. Denver is cheaper on income tax, property tax, sales tax, and gas, but homes cost roughly double to buy and rent runs higher. For renters, Chicago is usually cheaper; for long-term buyers, Denver’s lower taxes can close much of the gap.
Are homes cheaper in Denver than Chicago?
No. Census QuickFacts puts the median owner-occupied home value near $616,000 in Denver versus about $334,100 in Chicago — close to twice the price. Chicago is one of the more affordable big-city housing markets, the single biggest factor here.
Which city has lower taxes?
Colorado, on nearly every measure. Its income tax (4.40% flat) is lower than Illinois’s (4.95%), its base sales tax is far lower, and its effective property tax (about 0.50%) is roughly a third of Illinois’s 1.88% — the biggest single difference.
Do I need a car in Denver like I did in Chicago?
More likely, yes. Chicago’s CTA makes car-free living practical for many residents, while Denver’s RTD covers a more spread-out metro, so most households keep a car. If you’re leaving a car-free Chicago lifestyle, budget for vehicle costs in Denver.
Are salaries lower in Denver than Chicago?
Generally the opposite. Denver’s median household income is about $94,718 versus roughly $77,902 in Chicago, so higher local wages help offset the higher home prices — though the trade-off depends on your field and whether you keep a Chicago-based remote salary.
Is Denver cheaper to heat and cool than Chicago?
Usually a little, yes. Denver’s dry, sunny climate means shorter cold snaps and lower humidity, so heating and cooling tend to run less than through a long Chicago winter or muggy summer. The main exception is summer water, since Colorado is arid and outdoor watering adds up.
