Chicago has a cost of living index of 117.6, about 17.6% above the national average. The housing index is 143.8, so housing still does a lot to shape the local budget. Typical apartment rent is about $3,330 a month, and median home values are around $621,136. The median household income is approximately $72,000. That makes it one of the more affordable large cities in the country, especially considering what it offers in terms of scale and amenities.

Chicago's transit system, the L, covers much of the city and connects to a commuter rail network serving the suburbs. Many city residents live without a car, which meaningfully reduces transportation costs. Grocery prices are close to the national average, and the city's dining scene includes a wide range of price points. Utilities run slightly above average in winter due to heating costs.

Illinois has a flat state income tax of 4.95%, which is relatively straightforward to plan around. Cook County and the city of Chicago add sales taxes that push the combined rate to around 10.25%, one of the higher sales tax rates in the country. Property taxes in Chicago are also high relative to home values. Homeowners should factor property tax into total housing cost calculations, as effective rates can add $5,000 to $10,000 per year to the cost of owning a $400,000 home.

Oregon has a progressive income tax that reaches 9.9% at the top bracket and a 8.75% marginal rate beginning at $125,000 for single filers. There is no state sales tax in Oregon, which provides some relief on purchases and makes the city attractive for people who spend heavily on retail or dining. The absence of sales tax partially offsets the income tax burden for many residents.

One cost-of-living factor specific to Portland is utility bills. The Pacific Northwest's mild summers keep cooling costs low, and many residents go without air conditioning entirely, though the 2021 heat dome event prompted many to reconsider. Heating costs in winter are generally moderate. Portland's public transit system, TriMet, covers much of the city and some suburbs, giving car-free living a feasibility that not all mid-sized metros offer.
