Operator details
Wattwise is the product name. The deployment owner has not yet supplied a verified legal or trading name, postal address, company registration, or public operator biography. Those facts must be added and verified by the owner before a broad commercial launch; the site does not invent them.

The product promise
Anyone can calculate an appliance cost without an account. The first answer is quick, but it never hides the rate, usage, duty cycle, confidence, or excluded charges behind that answer.
People who want a complete picture can save a tariff, organize appliances by room, compare estimates with actual bills, test scenarios, and work through prioritized recommendations.
Designed for the household you live in
Wattwise keeps country, administrative region, billing currency, locale, language, time zone, tariff, climate, and appliance popularity separate. India retains DISCOM, slab, unit, and BEE support while households in every supported market receive their own terminology and assumptions.
Regional settings change rate-entry units, number and currency formatting, appliance recommendations, usage presets, tariff guidance, and applicable efficiency labels without duplicating the calculation core.
Independent recommendations
Recommendations are ordered by estimated savings, confidence, effort, comfort and safety—not hidden affiliate commission. Future commercial links must be visibly labeled and cannot change calculation results.
How estimates are produced
The calculation engine combines appliance-specific energy models, user-provided or clearly labelled representative inputs, the selected tariff, and explicit confidence factors. The Methodology and Data sources pages explain formulas, provenance, versioning, and limits.
