How we worked it out

  1. Energy per hour: 750 W ÷ 1,000 = 0.75 kWh
  2. Cost per hour: 0.75 kWh × $0.17 = $0.128
  3. Cost per day: × 15 hours = $1.91
  4. Month and year: × 30 days = $57.38, × 365 days = $698.06

  • The rate is an approximate residential average in Ohio. 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.
