About this calculator
This calculator multiplies a device's power draw in watts by how many hours a day you run it and your local electricity price per kilowatt-hour, converting raw wattage into an actual money figure — the daily, monthly and yearly cost of keeping that appliance running.
It's used by anyone trying to find where their electricity bill is going: households comparing the running cost of an air conditioner versus a space heater, renters deciding whether an old refrigerator or water heater is worth replacing, and small business owners estimating the cost of equipment like servers or freezers that run continuously. Because electricity prices and tariffs vary a lot by country and utility, plugging in your own rate turns a generic wattage spec on a device's label into a cost that's specific to your bill.
