A narrow job
LabelWatts exists to answer one practical question: what happens to an appliance’s annual cost estimate when you keep annual kWh fixed and enter a different electricity price?
The annual-kWh workflow comes first because it preserves the standardized energy-use figure supplied on an appliance label. A secondary watts mode supports people who have measured or credible average power and a runtime pattern.
Transparent by design
Each result keeps the formula, substituted values, units, price-source type, and limitations together. The tool does not save calculator values, create accounts, encode inputs in URLs, recommend appliances, or simulate provider pricing structures.
No advertising or affiliate code is included in the initial implementation.
Independence
Independent calculator. Not affiliated with or endorsed by the FTC, DOE, EIA, EPA, ENERGY STAR program, appliance manufacturers, or utilities. Program names are used only when needed to identify a source or explain a label.
The public operator is LabelWatts, the public contact is wooki.support@gmail.com, and the relevant operating jurisdiction is Republic of Korea. Questions, corrections, privacy requests, rights concerns, and accessibility feedback can use that public contact.
