Built this after seeing how many people are surprised by their electricity bill every month. Most people have no idea which appliance is responsible. Enter your wattage, daily hours, and rate and you get the exact number before the bill arrives. Works for any appliance, any country, any electricity rate. No signup, no ads, runs in your browser. Would love feedback on what features would make it more useful for your setup.
