What this tool does
Enter an appliance's wattage, how many hours per day it runs, and your electricity tariff to see daily, monthly and yearly cost.
Formula
Energy (kWh) = watts / 1000 × hours used. Cost = energy × your tariff (price per kWh). Repeat for each appliance and add the results for a multi-appliance total.
Frequently asked questions
How do I total multiple appliances?
Run the calculator once per appliance and add up the resulting costs - a future version may support entering several appliances at once.
