What is Detroit's cost-of-living index?

Detroit's composite cost-of-living index is about 80 on a scale where the US national average equals 100. That means living in Detroit costs roughly 20% less than the typical American city. The gap is driven overwhelmingly by housing, where Detroit's sub-index sits near 55 — among the lowest of any major US city.

Why is Detroit so much cheaper than the national average?

Housing is the dominant factor. Detroit's home prices and rents are far below national norms following decades of population decline that left abundant housing stock. Other categories like groceries, transportation, healthcare, and utilities track much closer to the national average (90 to 100), so the headline affordability comes almost entirely from cheap housing.

How do I convert my salary to a Detroit equivalent?

Multiply your current salary by Detroit's index (80) divided by your current city's index. For example, a $90,000 salary in a city with an index of 120 has the same purchasing power as $90,000 x (80 / 120) = $60,000 in Detroit. The tool does this automatically when you enter your salary and source index.

What does a cost-of-living index of 100 mean?

100 is the US national average baseline. A city with an index of 100 costs exactly the national average; an index of 80 means costs are 20% below average; an index of 120 means costs are 20% above average. The index is a weighted blend of housing, food, transportation, utilities, healthcare, and miscellaneous goods.

Are the monthly spending figures exact for Detroit?

No — they are estimates. The tool scales typical national-average single-person monthly budgets by each Detroit category sub-index to illustrate relative costs. Your actual spending depends on neighborhood, lifestyle, household size, and current prices. Use the figures for comparison, not as a precise budget.

Detroit Cost-of-Living Index — 80 vs US Average of 100

Detroit is one of the most affordable major cities in the United States. Its composite cost-of-living index is about 80 against a national average of 100, meaning the typical cost of living runs roughly 20% below the national norm. Almost all of that advantage comes from housing, where Detroit’s sub-index sits near 55. This tool breaks the index down by category and converts any salary into its Detroit purchasing-power equivalent.

How it works

Cost-of-living indices are built so that the US national average equals 100. Each category gets its own sub-index, and the composite is a weighted blend. The salary comparison uses the standard purchasing-power formula:

Equivalent Detroit salary = Current salary x (Detroit index / Source city index)

So if you earn $90,000 in a city with an index of 120, you would need only $90,000 x (80 / 120) = $60,000 in Detroit to maintain the same standard of living.

The monthly-spend estimates scale a typical national-average single-person budget by each Detroit sub-index, illustrating where the savings actually land.

Detroit category sub-indices

Category	Detroit index (US=100)
Housing	55
Groceries	94
Transportation	95
Utilities	100
Healthcare	92
Goods & misc.	96

The pattern is clear: everything except housing tracks close to the national average. Detroit’s affordability is fundamentally a housing story.

Notes and example

A $70,000 earner relocating from a national-average city (index 100) keeps the same buying power on roughly $56,000 in Detroit — because $70,000 x (80 / 100) = $56,000.
These are estimates blended from published survey data. Neighborhood matters enormously in Detroit, where housing costs vary widely between the suburbs and the city core.
Detroit levies a city income tax, which is not reflected in the cost-of-living index; factor it separately when comparing take-home pay.
