Mississippi Electricity Cost Calculator

Homes in Mississippi paid an average of 14.77¢ per kilowatt-hour from August 2025 to July 2026, 18% below the U.S. average of 17.99¢. That is the 18th-lowest of 51, between Kansas (15.09¢) and North Carolina (14.77¢).

The average Mississippi home used 1,160 kWh a month — the 3rd-most of the 51 — so its typical bill came to $171 a month, the 9th-highest. At the national rate the same 1,160 kWh would cost $37 more a month.

In July 2026, the latest month published, the Mississippi rate was 14.54¢.

At 14.77¢ per kWh, every extra 100 kWh a month adds $14.77 to the monthly bill and $177 to the year. The table runs from half to twice the Mississippi average home's 1,160 kWh, using the same calculation as the calculator above.

The average Mississippi home's bill peaked at about $228 in July 2026 and was lowest, about $132, in November 2025. Use ran from 854 kWh in April 2026 to 1,569 kWh in July 2026, 1.8 times as much.

The rate moved too, from 13.59¢ in August 2025 to 16.76¢ in April 2026. A monthly rate includes that month's fuel and seasonal charges, which is why the calculator uses the 12-month average for a yearly estimate.

Among the 10 largest providers listed, average residential rates in 2024 ran from 12.23¢ at Tombigbee Electric Power Assn to 15.00¢ at Magnolia Electric Power Assn. On the average Mississippi home's 1,160 kWh that is a difference of $32 a month.

These are 2024 figures, the latest final year. The Mississippi average was 13.39¢ that year and 14.77¢ over the last 12 months, up 10% — compare the providers with each other, not with today's average.

Together they serve 72% of Mississippi's 1,340,459 residential customers. The rates are each company's residential revenue divided by kilowatt-hours sold, so customer charges are included; a plan or tier can still differ.
