Appliance Load Calculator

Before the bill can be managed, it has to be explained. This is the units side of the story: what each appliance actually consumes in a month, with the arithmetic printed.

The reference figure: a 1.5-ton inverter AC at a typical 1,200 W average draw, 8 hours a day, uses 288 units a month on its own — more than the entire protected allowance. That is why summer bills cross bands that winter bills never approach.

What your appliances use in a month

Wattages are typical figures — edit any of them to the rating plate on your own appliance. The arithmetic is printed, not hidden: watts × hours a day × days ÷ 1,000 = units.

ApplianceWatts (typical)Hours / dayUnits / month
Inverter AC, 1.5 ton —
Inverter AC, 1 ton —
Non-inverter AC, 1.5 ton —
Ceiling fan —
Refrigerator —
Deep freezer —
LED bulb / tube light —
LED TV —
Washing machine —
Iron —
Water pump (1 hp) —
Room cooler —
Microwave oven —
Laptop / computer —

Days in the month are counted as 30. An inverter AC's draw falls once the room cools — its figure here is a running average, and editing it is the honest way to match your home.

Units are only half the story — bands are the other half

288 units of AC do not cost 288 × “the rate”, because there is no single rate: the band your total lands in prices every unit. Moving from 190 to 210 total units reprices the whole month. So use this page to find the load, then the bill calculator to price it — and if you are close to a boundary, the cliff guide shows what one appliance-hour a day is worth at the edge.
