Average Electricity Bill in Idaho
A typical household in Idaho pays about $114.30 a month for electricity — roughly $1371.60 a year — at the state average rate of 12.70 ¢/kWh. That's about $714.96 a year less than the typical U.S. household pays. That's based on 900 kWh of monthly use at the all-in average rate — delivery, fixed charges, and utility fees are already inside it; locally billed taxes vary by area.

Is this what you'll actually pay?
It's a fair benchmark, not a forecast. We take Idaho's average rate of 12.70 ¢/kWh and apply it to 900 kWh a month at the all-in average rate, which comes to $114.30. That rate already includes delivery, fixed charges, and utility fees; locally billed taxes vary by area.
Your own bill can land well above or below that, depending on how much you run the air conditioning, how you heat your home and water, your home's size, and how your utility designs its rates.

Source & Method
Source: U.S. Energy Information Administration (EIA) Retail Sales of Electricity. Updated: April 2026. Estimates use the EIA all-in average residential rate — energy, delivery, fixed charges, and utility fees together, not just the electricity itself. Fees are inside the rate, not an extra on top; how your own bill splits fixed versus per-kWh charges varies by utility. For what's inside the all-in rate, see hidden electricity fees; for how rates and estimates are defined, see the methodology hub.
