How we worked it out

  1. Energy per hour: 1,000 W ÷ 1,000 = 1 kWh
  2. Cost per hour: 1 kWh × $0.32 = $0.32
  3. Cost per day: × 4 hours = $1.28
  4. Month and year: × 30 days = $38.40, × 365 days = $467.20

  • Wattage is the typical label value, not a measured value. Check the label on your own appliance.
  • The rate is an approximate residential average in California. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
  • A month is 30 days and a year is 365 days.
