How Much Electricity Does a House Use Per Month?

There is no single monthly electricity-use number that applies to every home. Consumption depends on home size, climate, heating and cooling, appliances, occupancy, and daily habits.

A useful starting point is to record the kWh shown on each electricity bill. For example, 900 kWh at an effective energy rate of $0.16 per kWh would represent $144 for the energy portion. Actual bills can include fixed charges, taxes, fees, or tiered pricing.

To understand household consumption, list major loads first: air conditioning, heating, water heating, refrigeration, cooking, laundry, electronics, and lighting.

Then estimate individual appliances with the WattBillGuide Electricity Cost Calculator. Start with devices that have high power ratings or operate for many hours.
