From wattage and hours, energy is watts ÷ 1000 × hours and cost is that kWh × your tariff: a 1500 W heater running 5 hours uses 7.5 kWh, costing ₹60 a day at ₹8 — ₹1,800 a month, which is how a single heavy device quietly dominates a bill. The page shows daily and monthly cost together so the annual habit is visible.
Enter the rating-plate watts, the hours the device actually draws power (not merely stays plugged in), and your tariff. Motors, ACs, and fridges cycle — a 1.5-ton AC rated 2000 W may average far less over a night — so use average running hours or the figure smartens into an upper estimate. Rank every suspect device this way; the top one is your savings target.
It does not measure real draw, add standby consumption, or apply slab tariffs — it prices rated watts against running hours, with a plug-in meter as the next step for truth.
Upper estimate — cycling devices draw less than rated.
On the appliance's rating label or manual. For devices that cycle, an average or 'running watts' figure is more realistic than the peak rating.
No. Add standby consumption separately if it matters for always-on devices.
Heating and cooling: geysers, room heaters, ACs, and irons — anything that turns electricity directly into heat or cold at kilowatt scale.
