How to Calculate Electricity Cost
Convert wattage to kilowatts, multiply by usage hours to get kWh, then multiply by your utility rate.
Formula
Daily kWh = Wattage / 1000 x Hours Per Day
Daily Cost = kWh x Rate Per kWh
Exemple Résolu
A 1,500W space heater running 4 hours/day at $0.14/kWh.
- 01Daily kWh = 1,500 / 1,000 x 4 = 6.0 kWh
- 02Daily cost = 6.0 x $0.14 = $0.84
- 03Monthly cost = $0.84 x 30 = $25.20
- 04Annual cost = $0.84 x 365 = $306.60
