Every appliance in your home draws a different amount of power, and that wattage — combined with how often you use it — is what actually drives your electric bill. Our appliance wattage calculator estimates the running wattage for common household appliances, from refrigerators to space heaters, so you know exactly what’s pulling power in your home.
This is especially useful in a few specific situations: sizing a generator or battery backup system for outages, deciding whether an appliance upgrade is worth the cost through energy savings, or simply figuring out which device is quietly running up your bill. Space heaters, electric water heaters, and older refrigerators tend to be the biggest surprises for most homeowners.
Once you know your appliances’ wattage, our electricity cost calculator converts that into an actual dollar estimate based on your local electricity rate, so you can see the real monthly cost of running any given device.
