How do I calculate kWh cost?
kWh Explained To calculate the kWh for a specific appliance, multiply the power rating (watts) of the appliance by the amount of time (hrs) you use the appliance and divide by 1000. This 60-watt lightbulb that we used for 90 hours in a month when we were charged $0.09/kWh cost us approximately 50 cents for the month.
What is the formula of kW?
Basic electrical theory tells us that for a single-phase system, kW = (V × I × PF) ÷ 1,000. kW = (V × I) ÷ 1,000.
How do you calculate kW in a house?
- Hi there,
- To calculate the electrical load of a house, you need to understand the number of appliances that run in your house.
- The amount of electricity required to run:

How do you calculate power consumption per day?
How to Calculate Power Consumption in kWh?
- Daily Power Consumption. Daily Power Consumption = Wattage rating x time in hours. 2000 Watts x 3 Hrs = 6000 Watts-Hour.
- Monthly Power Consumption. Monthly Power Consumption = Wattage rating x time in hours. 2000 Watts x 3 Hrs x 30 days = 180000 Watts-Hour. ...
- Annual Power Consumption.
