Electricity Bill Calculator

Estimate your DisCo bill using NERC’s Band A-E tariffs, or see how many units a prepaid top-up buys

Estimated monthly bill

₦20,950

100 kWh @ ₦210/kWh (Band A)

Lifeline tariff: if your total usage for the month is 50kWh or less, you pay a flat, subsidised rate of ₦4/kWh on all of it — regardless of your band. Above 50kWh, your full usage is billed at your band’s normal rate.

Estimates only, based on NERC-approved (or, for Enugu State, EERC-approved) Non-MD residential tariffs as of May 2026. Actual bills may include estimated-billing adjustments, meter charges, or arrears not captured here. Commercial/industrial (MD1, MD2) rates are not covered by this calculator.

How Electricity Bands Work in Nigeria

Nigeria’s Service-Based Tariff system classifies every customer into a band — A through E— based on the average daily hours of electricity their feeder actually receives. Band A gets 20 or more hours a day and pays the highest rate; Band E gets as little as 4 hours and pays the lowest. You can’t choose your band — it’s determined by the infrastructure serving your area, and your DisCo is required to publish and honour the hours of supply it commits to for each band.

As of May 2026, Band A costs ₦209.50 per kWh at all 11 NERC-regulated distribution companies (DisCos) across Nigeria, a rate that has been frozen since July 2024. Bands B through E have been frozen even longer, since December 2022, and vary by DisCo. The one exception is Enugu State, which took over its own electricity regulation in 2025 — its utility, MainPower, charges ₦160 per kWh for Band A, a lower rate set by the state regulator rather than NERC.

Regardless of band, anyone using 50kWh or less in a month pays a flat, subsidised lifeline rate of ₦4/kWh on their entire usage — a meaningful discount for low-consumption households that this calculator applies automatically.

This calculator estimates your bill from a known usage in kWh, or works in reverse to estimate how many units a prepaid recharge amount will buy — useful for budgeting a top-up before you buy it.
