How electricity units are calculated
A unit of electricity is one kilowatt-hour (kWh) — the energy a 1,000-watt appliance uses in one hour. When you buy a prepaid token, 7.5% VAT is taken out first, and the rest is divided by your band's tariff:
Units = (Amount ÷ 1.075) ÷ Tariff per kWh
For example, ₦20,000 on Band A at ₦209.50/kWh gives (20,000 ÷ 1.075) ÷ 209.5 ≈ 88.8 units.
Tariffs differ slightly between distribution companies (AEDC, IKEDC, EKEDC, PHED, KEDCO, JED and others) and NERC reviews them regularly. The preset rates are approximate — pick "Enter my own rate" and use the rate on your latest token receipt for an exact answer.
