Energy Consumption Calculator
Calculate the energy consumption and electricity costs of your household appliances. Understand how usage patterns, appliance wattage, and electricity rates affect your energy bills.
Step 1: Appliance Details
Understanding Wattage
Wattage indicates how much electricity an appliance uses when operating. Common appliances range from 10W (LED light) to 5000W (electric heater). Check your appliance’s label or manual for accurate wattage.
Step 2: Electricity Details
About Electricity Rates
Electricity rates vary by location, time of day, and consumption level. Check your utility bill for your exact rate. Time-of-use rates may be lower during off-peak hours (usually nights and weekends).

Energy Cost Analysis
Energy Consumption Formula
Energy (kWh) = (Wattage × Hours × Days) ÷ 1000
The energy consumption is calculated by multiplying appliance wattage by daily usage hours and days per month, then dividing by 1000 to convert to kilowatt-hours (kWh).
