Iowa Electricity Prices

Iowa sits mid-pack — 15.99¢ per kilowatt-hour in July 2026, 28th-highest of 51 and 17.0% below the national benchmark.

At Iowa's July 2026 average of 15.99¢/kWh, 10,500 kWh of annual use works out to $1,679 a year — around $140 a month. Running the same 10,500 kWh calculation at the July 2026 national benchmark rate gives $2,022 — a $343 gap between the two published averages, less for Iowa, not a bill either way.

Over the full EIA series the Iowa jurisdiction average has risen 109% since January 2001, from 7.66¢ to 15.99¢ in July 2026 — a compound 2.9% per year. Iowa is among the most month-to-month variable third of jurisdictions.

Yes. The July 2026 average of 15.99¢ per kilowatt-hour is the highest monthly figure Iowa has recorded across the EIA series, which begins in January 2001. The previous floor for the jurisdiction was 7.65¢ in January 2002.

August. Measured over the 25 complete calendar years the EIA series covers for Iowa, 2001 through 2025, August runs highest relative to its own year and January runs lowest — a swing of roughly 23.7 percentage points.

Among Iowa and its land-border neighbours in July 2026, Iowa posts the lowest average at 15.99¢ and Illinois the highest at 19.22¢. That makes Iowa the cheapest in the group, at 15.99¢.

Almost certainly not exactly, and this is the one caveat that governs every figure on this page. The published value is the EIA residential average across every utility and residential rate class in Iowa for July 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 12.60¢ in December 2025 and 15.99¢ in July 2026. Your own rate depends on your utility, tariff, usage tier, time-of-use schedule, and fixed monthly charges, none of which this index models. Read your bill for the rate that applies to you.
