How we worked it out

  1. Energy per hour: 4,000 W ÷ 1,000 = 4 kWh, × 50% of the time at full power = 2 kWh
  2. Cost per hour: 2 kWh × $0.155 = $0.31
  3. Cost per day: × 3 hours = $0.93
  4. Month and year: × 30 days = $27.90, × 365 days = $339.45

How to spend less: Keep the insulated cover fitted when not in use and check for heat loss.

What this estimate assumes

  • The appliance draws full power about 50% of the time, because it cycles on and off.
  • 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 Florida. 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.
