How to Use This Calculator
Select your NERC tariff band, then add each appliance you use with its daily usage hours. The calculator shows monthly kWh consumption and electricity cost for your entire household. Use this to identify energy-hungry appliances and plan solar or generator sizing.
The Formula
Daily kWh (per appliance) = Power (kW) × Hours/Day
Monthly kWh = Daily kWh × 30
Monthly Cost = Monthly kWh × NERC Rate (₦/kWh)
Total = Sum of all appliances

Air Conditioner (1.5HP)1.5 kW = ₦337.5/hr on Band A
Refrigerator0.15 kW = ₦33.75/hr on Band A
Electric Iron1.0 kW = ₦225/hr on Band A
LED Bulb (9W)0.009 kW = ₦2.025/hr on Band A
FAQ
Air conditioners are by far the biggest electricity consumers — a 1.5HP split AC running 8 hours/day uses 12 kWh/day = 360 kWh/month. Compare this to a refrigerator (0.15kW × 24hrs = 3.6 kWh/day = 108 kWh/month) or 4 ceiling fans (4 × 0.07kW × 10hrs = 2.8 kWh/day = 84 kWh/month). Switching from AC to fans can reduce electricity consumption by 60–70% for cooling alone.
Key savings: Replace all bulbs with LED (9W LED vs. 60W incandescent = 85% saving). Reduce AC use — each hour less saves ~1.5 kWh. Use a programmable thermostat (26°C instead of 18°C cuts AC consumption by ~30%). Unplug appliances on standby (TVs, chargers draw 2–10W continuously). Use a chest freezer instead of upright (30% more efficient). Service your AC annually (dirty coils increase power use by 15–20%).
On Nigerian prepaid meters, press the # button to cycle through readings. The display shows current kWh balance (remaining units), total kWh consumed, current power draw in Watts, voltage, and other readings. Track your daily consumption by checking the balance each morning — the difference is yesterday's kWh usage. Apps like "Meter Reader" can help track usage history.
