Every input includes a simple explanation.
Private: the calculation runs in your browser. Your inputs are not sent to GharGanit.
Rated power can be different from average power while the appliance is running.
Voltage, automatic on-off cycling and equipment condition can change real use.
Use this as a budget estimate. The appliance label, how often it runs and all charges on your tariff determine the real bill.
Viewing energy and standby energy are calculated separately, showing when a small standby load matters over many idle hours.
Use the model's on-mode consumption at normal brightness and check whether accessories such as a set-top box need their own calculation.
Screen size alone does not determine wattage, and the TV estimate should not silently include unrelated devices.
Energy (kWh) = watts × quantity × hours × days × operating factor ÷ 1,000
