Connecticut's manufacturing cost index stands at 128.6 against a national 100 as of June 2026 — labor at 110.7 and industrial energy at 182.1. That places it 44th cheapest of 51 jurisdictions.

• composite (US = 100): 128.6
• labor: 110.7
• industrial energy: 182.1

The composite weights labor at 75% and industrial electricity at 25%, so Connecticut's position is mostly a energy story: its energy component indexes at 182.1 against the national 100. A premium of 29 points compounds differently across shops — a labor-heavy job shop feels the labor line, an energy-hungry process plant feels the kilowatt-hours.

For a site decision the index is the starting point, not the answer: freight to customers, workforce depth, and incentives move individual cases. The per-state page carries the underlying wage and electricity series this index is built from, both refreshed automatically.
