Why the Montana bill is what it is
A bill is kilowatt-hours multiplied by price, and states reach similar bills by very different routes. Montana's electricity costs 23% less than the U.S. average, and the typical Montana home uses 1% less of it, so the bill lands 24% below the national average. Both work in the same direction: price and usage are each below the national figure.
Compare District of Columbia: households there pay almost the same bill ($113.23 against $107.91) at a rate 1.4 times Montana's — 17.71¢ against 12.66¢ — because they use 639 kWh a month where Montana homes use 852.
At today's rate
The 2024 figures are the latest annual numbers EIA has published. Montana's average residential rate has since moved to 15.14¢/kWh (June 2026). At the same 852 kWh a month, that puts the typical bill near $129.02 — 20% higher. That is an estimate: it holds usage at 2024 levels, and usage swings with the weather.
