Manufacturing in Maine Runs 19% Above the National Cost Average

Maine's manufacturing cost index stands at 118.9 against a national 100 as of July 2026 — labor at 111.0 and industrial energy at 142.7. That places it 41st cheapest of 51 jurisdictions.

• composite (US = 100): 118.9
• labor: 111.0
• industrial energy: 142.7

The composite weights labor at 75% and industrial electricity at 25%, so Maine's position is mostly an energy story: its energy component indexes at 142.7 against the national 100. A premium of 19 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.
