Missouri Electricity Prices

Relatively, yes — 13.68¢ per kilowatt-hour in May 2026, 7th-cheapest of 51 and 29.5% below the national benchmark.

At Missouri's May 2026 average of 13.68¢/kWh, 10,500 kWh of annual use works out to $1,436 a year — around $120 a month. Running the same 10,500 kWh calculation at the May 2026 national benchmark rate gives $2,037 — a $601 gap between the two published averages, less for Missouri, not a bill either way.

Over the full EIA series the Missouri jurisdiction average has risen 133% since January 2001, from 5.87¢ to 13.68¢ in May 2026 — a compound 3.4% per year. Missouri is among the most month-to-month variable third of jurisdictions.

June 2025, at 15.91¢ per kilowatt-hour. The May 2026 reading of 13.68¢ sits 14.0% below that peak. The lowest monthly average on record was 5.87¢ in January 2001.

June. Measured over the 25 complete calendar years the EIA series covers for Missouri, 2001 through 2025, June runs highest relative to its own year and January runs lowest — a swing of roughly 31.5 percentage points.

Among Missouri and its land-border neighbours in May 2026, Oklahoma posts the lowest average at 13.38¢ and Illinois the highest at 23.85¢. Missouri ranks 2nd of 5 in the group, at 13.68¢.

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 Missouri for May 2026 — a benchmark, never a billed amount. Even the jurisdiction figure is not one number — across the trailing year it moved between 11.80¢ in January 2026 and 15.91¢ in June 2025. 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.
