How Many Watts of Electricity does a Garbage Disposal use?

Real power-use measurements from a garbage disposal.

How Much Power does a Garbage Disposal use

Garbage Disposal: 246 Watts


  • With a function similar to a blender, a garbage disposal uses a simple blade to smash up vegetable peels and eggshells which are dumped into the sink. This is probably the scariest electrical appliance in your house, unless you have a radio perched near the bathtub.
  • 246 watts, about the same amount of power as a blender. Probably operates at lower speed, but the motor is much larger, so it either has more torque or is engineered for greater longevity.
