How Much Electricity Does a Microwave Use Per Minute?

par

Microwaves are designed to cook food quickly, which helps limit electricity consumption compared to appliances that run longer.

Microwave Power Consumption

Most microwaves use:

  • 800–1,200 watts while operating

Because microwaves are used for short periods, their overall energy use stays low.

Cost Per Minute

Example using a 1,000-watt microwave:

1 kWh ÷ 60 × $0.20 ≈ $0.003 per minute

Even daily use adds only a small amount to your electricity bill.

Microwave vs Other Appliances

Microwaves generally use less electricity than:

  • Electric ovens

  • Dishwashers (see: Does a Dishwasher Use a Lot of Electricity?)

  • Electric kettles

Tips to Reduce Microwave Energy Use

  • Avoid unnecessary reheating

  • Use appropriate power levels

  • Keep the door seal clean
