- Daily Consumption (kWh) = (Wattage x Hours Used) / 1000
Daily = (150 x 24) / 1000 = 3.6 kWh
Monthly Consumption Calculation:
- Monthly Consumption = Daily Consumption x 30 days
Monthly = 3.6 x 30 = 108 kWh
Estimating Cost:
- If your energy cost is $0.12 per kWh:
- Monthly Cost = Monthly Consumption x Cost per kWh
- Monthly Cost = 108 x 0.12 = $12.96
