Appliance Electricity Cost Calculator — See What Each Device Costs You

Air conditioners, water geysers and refrigerators are typically the top three — ACs and geysers because of their high wattage, and refrigerators because they run continuously. Add your own mix above to see which one dominates your specific household.

Each appliance's monthly units = (wattage × hours used per day × 30 days) / 1000. All your appliances' units are then summed into one household total and priced through your real DISCOM's progressive slab tariff — not each appliance billed separately.

1 unit = 1 kWh (kilowatt-hour) — the energy a 1000-watt appliance uses running for one hour. It's the billing unit every DISCOM in India uses on your meter and bill.

A typical 1.5-ton 3-star split AC draws roughly 1.5-1.6 units per hour of continuous run-time; a 5-star unit of the same size draws less, around 1.2-1.3 units per hour — add yours above with your actual daily hours for a precise figure.

A standard ceiling fan (about 70W) run 12 hours a day uses roughly 25.2 units a month — a BLDC fan of the same airflow can use roughly a third of that for the same hours.

For a typical 200L 3-star fridge running continuously, expect somewhere around 108 units a month at the reference wattage used here — your real bill impact depends on your fridge's actual rating label and duty cycle, and the tariff slab it lands you in. Add it to the builder above for your own DISCOM's real number.

A standard induction-motor ceiling fan typically draws 60-75 watts; a modern BLDC ceiling fan draws roughly 25-30 watts for similar airflow — check your own fan's rating label for its exact figure.

The household builder above is scoped to residential/domestic connection types. For a shop or office, use our full DISCOM bill calculators under the Electricity hub and select the Commercial connection type there — commercial slabs and fixed charges differ from domestic ones.

Yes — every DISCOM tariff file carries its own source link and last-verified date (shown in the trust section above), and we periodically re-check them against the DISCOM's own tariff order. Appliance wattage reference figures are separately dated too.

Start with your biggest line items — usually AC and water heating. Raise your AC thermostat a couple of degrees, use geysers on a timer instead of standby-heating, unplug idle chargers and routers when not needed, and prefer BEE 5-star or BLDC appliances where you're replacing an old unit. See the tips section above for specifics.
