A Materials Engineers in California earns a median salary of $128,470 per year. After adjusting for California's cost of living (RPP=112.5), the real purchasing power is $114,195 — a -11.1% difference.
California's cost of living is 12.5% higher than the national average according to the BEA Regional Price Parities (2022). The RPP index for California is 112.5 (US average = 100).
Regional Price Parities (RPPs) are price indexes published by the U.S. Bureau of Economic Analysis (BEA) that measure differences in price levels across states. They are expressed as a percentage of the national average (US = 100). Higher RPP means higher cost of living.
The adjusted salary is calculated as: Nominal Salary x (100 / RPP). For a Materials Engineers in California: $128,470 x (100 / 112.5) = $114,195. This represents what the salary would be worth in a state with average living costs.
Partially — a Materials Engineers's nominal salary of $128,470 in California has 11.1% less purchasing power due to higher living costs. The real value is $114,195. However, California may offer better career opportunities, networking, and industry access.
