How Appliance Calculator Works
Step 1: List all the electrical appliances in your home.
- From the Tool Select appliance from the list and then select Add.
- Example: Fridge, TV, lights, air conditioner, fan, etc.
Step 2: Get the wattage (W) or kilowatt (kW) each appliance uses.
- Example: 1 Ton Air Conditioner = 1000 W = 1 kW.
Step 3: Determine how many hours per day you use the appliance
- Example: TV = 3 hours, Fridge = 24 hours, Fan = 5 hours.
Step 4: Tool will calculate watt-hours for each appliance (W × hours).
-
Example: TV = 100 W × 3 hours = 300 Wh
-
Fridge = 150 W × 24 hours = 3600 Wh
Step 5: Tool will add up all the watt-hours to get your total daily electricity usage.
- Example: 300 + 3600 + … = Total Wh / kWh
Step 6: Tool will calculate the total power of all appliances
- Example: 100W + 200W = 300W or 0.3kW
Step 7: Tool will calculate the total monthly watt-hours
- Example: 100 Wh + 400Wh = 500Wh or 0.3kWh
Step 8: If you want your monthly electricity cost, multiply your daily kWh by the number of days in the month (30).
Example: Daily usage = 4 kWh, month = 30 days
4 kWh × 30 = 120 kWh per month
Then multiply by the price per kWh to get your monthly cost
