💡 Energy Saving Tips
• Switch to LED bulbs (90% less energy)
• Unplug devices when not in use (phantom load)
• Use fans before reaching for AC
• Run heavy appliances during off-peak hours
• Set fridge to 3-5°C, freezer to -18°C
• Consider solar for daytime loads
• Use pressure cookers (70% less energy than pots)
• Insulate your water heater/geyser
📊 Average Household Usage
Nigeria: 50-150 kWh/month
Kenya: 60-120 kWh/month

The Electricity Bill Estimator calculates your monthly electricity costs based on actual tariff structures from major African power utilities including NERC in Nigeria, KPLC in Kenya, Eskom in South Africa, and ECG in Ghana. Select your country, enter your appliances or total consumption, and the tool applies the correct tiered pricing bands to estimate your bill. It accounts for service charges, VAT, and fuel surcharges where applicable. This is invaluable for households trying to budget utility expenses, landlords splitting bills, and anyone comparing the cost of running specific appliances across different tariff bands.

Sources & verification

Electricity bills need current tariff checks

This estimator combines your listed appliances, hours, quantity, selected country tariff model, outage hours, fuel assumptions, and solar coverage into a household planning estimate.

Planning estimate

Reviewed 2026. Tariffs, bands, VAT, fixed charges, fuel prices, and exchange rates can change.

Methodology

  • Daily kWh is calculated from appliance wattage, run hours, and quantity, then multiplied into a monthly estimate.
  • Generator comparison estimates fuel from kWh output, while the solar slider estimates savings and system size from your calculated load.
  • The outage plan separates critical load from whole-home load so backup sizing is not accidentally oversized.

Before acting

  • Confirm the current utility tariff, service band, prepaid meter rules, fixed charges, taxes, and fuel price.
  • Ask an installer to verify inverter surge, usable battery capacity, wiring, roof condition, and protection devices before purchase.
  • Use copy or TXT download to share the estimate with a landlord, installer, accountant, or facilities reviewer.

Frequently Asked Questions

Which countries are supported?
Nigeria (NERC bands A-E), Kenya (KPLC tiers), South Africa (Eskom blocks), Ghana (ECG tiers), Tanzania (TANESCO), Uganda (UMEME), Ethiopia (EEU), Egypt (EEHC), Rwanda (REG), and Cameroon (ENEO). Each uses published tariff structures.
How accurate are the tariff rates?
Rates reflect publicly available tariff schedules. Actual bills may include fixed charges, taxes, levies, and VAT not captured here. Use results as estimates only.
How does the generator comparison work?
The tool estimates what it would cost to generate the same kWh using a petrol generator (typically 3-4 kWh per litre). This helps you compare grid vs generator costs — especially useful in countries with frequent outages.
What are Nigeria's electricity bands?
Customers are classified A through E based on hours of supply. Band A gets 20+ hours daily at ₦225/kWh, Band B gets 16-20 hours at ₦63.36/kWh, Band C 12-16 hours at ₦50.45/kWh, Band D 8-12 hours at ₦40.98/kWh, and Band E 4-8 hours at ₦31.59/kWh.
How does the solar savings estimate work?
After calculating your bill, adjust the solar coverage slider (20-100%) to see how much you could save. The tool estimates the system size needed and typical payback period based on residential solar costs in your country.
