How we worked it out

  1. Energy per hour: 2,000 W ÷ 1,000 = 2 kWh
  2. Cost per hour: 2 kWh × $0.13 = $0.26
  3. Cost per day: × 4 hours = $1.04
  4. Month and year: × 30 days = $31.20, × 365 days = $379.60

What this estimate assumes

  • The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
  • 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 Tennessee. 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.
