How Much Electricity Does a Microwave Use?

par

Microwaves are efficient for heating food. Their electricity use depends on wattage and cooking time.

Microwave Wattage

Typical wattages:

  • 600W – 800W (small models)

  • 900W – 1,200W (medium models)

  • 1,200W – 1,500W (large models)

Cost Per Minute

Example: 1,000W microwave running for 3 minutes:

1kW × 0.05 hours = 0.05 kWh

Cost:

0.05 × $0.20 = $0.01

Monthly Cost (Daily Use)

Using 10 minutes per day:

1kW × 0.167 hours = 0.167 kWh/day
0.167 × $0.20 ≈ $0.03/day
≈ $0.90/month

Tips to Reduce Energy Use

  • Use microwave instead of oven (much cheaper)
