Electricity Bill Calculator by Tariff Band (A–E)

Band A customers pay roughly four times what Band C customers pay for the same electricity, because Band A was moved onto a cost-reflective tariff in April 2024. Before you accept a bill or a vending receipt, work out what your units should actually cost — and check which band your feeder is on.

Before you rely on this

Band A is a national rate. Bands B to E are NERC reference rates that each DisCo prices differently, and they have been frozen since December 2022. Ikeja Electric, KEDCO, EEDC and PHED all bill different Band C rates.
If you consistently receive far fewer hours than your band promises, you can ask your DisCo to be reclassified. Band A requires 20+ hours a day.

Prefilled rates are national reference values. Your own receipt, payslip or pump price always overrides them.

Frequently asked questions

How much is one unit of electricity in Nigeria?

One unit is one kilowatt-hour. Band A pays about ₦209.50 per unit, Band B about ₦62.48, and Bands C to E between ₦40 and ₦50 at the national reference rates — before VAT. Your DisCo's approved rate for Bands B–E may differ.

How do I find out my electricity band?

Check the rate printed on your last prepaid vending receipt or monthly bill. Around ₦209.50 per unit means Band A; ₦40–₦70 means Bands B to E. You can also confirm through your DisCo's app or customer line by quoting your meter number.

Why is Band A so much more expensive?

Band A feeders deliver 20 to 24 hours of supply a day, and in April 2024 NERC moved those customers onto a cost-reflective tariff that removed most of the subsidy. Bands B to E remain subsidised, which is why their rates are so much lower even though they get less power.

Is the Band A rate the same everywhere?

Mostly, but NERC can approve a different rate per DisCo. EEDC has billed Band A at ₦160 per unit against the ₦209.50 national figure. Your receipt is what counts.
