You might make less money in Detroit than you would in San Francisco, but your Motor City salary can take you a lot further.

That’s according to Glassdoor’s new list of 25 U.S. cities with the best cost of living ratios—the higher the ratio, the more money people can save [[or spend)...

1. Detroit
Median Base Salary: $61,500
Median Home Value: $123,100
Cost of Living Ratio: 50%

Unsurprisingly, big cities known for high housing prices have much lower ratios. With a median base salary of $70,000 and a median home value of $384,100, New York’s ratio comes in at 18%. Boston, which has similar figures, has a slightly lower ratio of 17%.
