Hawaii's Regional Price Parity (RPP) is 110.8, meaning prices are 10.8% higher the national average. A Mechanical Engineers earning $98,740 in Hawaii has the equivalent purchasing power of $89,115 in an average-cost US state.
Every dollar goes further in low-cost states. Here is how each salary percentile compares after adjusting for Hawaii's cost of living.
| Percentile | Nominal Salary | COL-Adjusted | Difference |

Hawaii's RPP of 110.8 puts it 10.8% above the national baseline cost of living. A Mechanical Engineers needs that premium in nominal pay just to maintain the same purchasing power as an average-cost state.
After applying Hawaii's RPP, the $98,740 median salary translates to $89,116 in real terms — a 9.7% loss. That difference can cover several months of expenses over a year for a Mechanical Engineers.
Hawaii ranks #51 of 51 — bottom quartile for Mechanical Engineers real purchasing power. Relocation, employer negotiation, or remote roles at higher-paying markets tend to generate the biggest ROI.

A Mechanical Engineers in Hawaii earns a median salary of $98,740 per year. After adjusting for Hawaii's cost of living (RPP=110.8), the real purchasing power is $89,115 — a -9.7% difference.
Hawaii's cost of living is 10.8% higher than the national average according to the BEA Regional Price Parities (2022). The RPP index for Hawaii is 110.8 (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 Mechanical Engineers in Hawaii: $98,740 x (100 / 110.8) = $89,115. This represents what the salary would be worth in a state with average living costs.
Partially — a Mechanical Engineers's nominal salary of $98,740 in Hawaii has 9.7% less purchasing power due to higher living costs. The real value is $89,115. However, Hawaii may offer better career opportunities, networking, and industry access.
