Calculate your monthly electricity consumption and costs. Track appliance usage and find energy-saving opportunities.
Calculate your monthly electricity usage and costs based on appliance consumption.
The Monthly Electricity Consumption Calculator helps you track and optimize your home's energy usage by calculating power consumption across all appliances. Understanding where your electricity goes is the first step toward meaningful savings and reduced environmental impact.
According to the U.S. Energy Information Administration, the average American household uses about 900 kWh per month, costing approximately $100-$150. HVAC systems account for 46% of this usage, followed by water heating (14%), lighting (9%), and refrigeration (7%). By tracking individual appliance consumption, you can identify energy hogs and prioritize efficiency improvements.
Don't forget standby power (phantom loads) which can add 5-10% to your bill.
| Appliance | Watts | Monthly kWh* |
|---|---|---|
| Central AC | 3,000-5,000 | 300-600 |
| Electric Water Heater | 4,000-5,500 | 350-500 |
| Refrigerator | 150-400 | 100-150 |
| Clothes Dryer | 2,000-5,000 | 60-100 |
| LED Light Bulb | 8-12 | 3-5 |

Consumption = Power (watts) x Hours used x Days / 1000 = kWh. Your bill = kWh x rate per kWh. Average US home uses 900 kWh/month.
HVAC systems (46%), water heating (14%), lighting (9%), and refrigeration (7%) are the biggest energy consumers. Electronics and appliances make up the rest.
Use LED bulbs, set thermostat to 68F/20C, unplug unused devices, use Energy Star appliances, and run appliances during off-peak hours for lower rates.
