Columbus, Ohio is one of the more affordable large US metros. Its composite cost-of-living index sits near 92 against a national average of 100, driven mainly by below-average housing. This free tool shows the category breakdown and converts a salary into its Columbus-equivalent purchasing power.
How it works
A cost-of-living index expresses local prices relative to a national base of 100. To convert a salary from one city to another you scale by the ratio of their indices:
equivalent salary = salary × (Columbus index ÷ comparison index)
So a salary in a city indexed at 110 needs only × (92 ÷ 110) to maintain the same standard of living in Columbus. The composite index is itself a weighted blend of category sub-indices:
housing ~ 83
groceries ~ 98
utilities ~ 99
transportation ~ 96
healthcare ~ 95
composite ~ 92
Example
Earning $80,000 in a city indexed at 100 (national average): the Columbus-equivalent is 80,000 × (92 ÷ 100) = $73,600. You can maintain the same lifestyle on about $6,400 less per year because Columbus is cheaper.
Notes
Housing does the heavy lifting here — if you rent or buy in a pricier Columbus suburb your personal index will be higher than the metro composite. Categories like groceries and healthcare are close enough to the national average that they barely move the needle.
