How to use this calculator
If possible, measure the appliance with a plug-in energy meter over a representative period. For refrigerators and climate-control equipment, a real reading is usually more useful than assuming they run continuously at rated power.
Enter the power or measured consumption, usage hours and approximate price per kWh. Then compare monthly and yearly costs.
If an appliance represents a significant part of your spending, consider usage habits, scheduling, maintenance or replacement.
Basic formula
For a simple estimate:
kWh = (vatios ÷ 1000) × horas de usoThen:
coste = kWh × precio por kWhStandby consumption is calculated separately and added to the main consumption.
