Field notes
The page accepts several forms of appliance energy data, including label wattage, annual kWh, per-use consumption, and monthly kWh. A recent household bill can supply a comparison rate when the user does not know the kWh price, though the site notes that this blends in base charges and taxes. Results can be saved locally, copied, shared, or printed, while the estimate remains deliberately simpler than a full Korean progressive-rate calculation.
