Cost of Living Calculator — Formula
## How Cost of Living Adjustments Work
Cost of living indexes compare the relative expense of different cities. Scale your salary proportionally to maintain the same purchasing power.
### Formula
**Equivalent Salary = Current Salary x (New City Index / Current City Index)**
An index of 100 is the national average. Higher means more expensive.

Esempio Risolto
You earn $70,000 in a city with COL index 100 and are moving to a city with index 130.
- Ratio = 130 / 100 = 1.30
- Equivalent salary = $70,000 x 1.30 = $91,000
- You need $21,000 more to maintain the same lifestyle
- Cost increase = 30.0%
