Which Appliances Are Actually Driving Your Electricity Bill?

Air conditioning usually gets blamed for a high summer bill, and it's often the single biggest contributor — but "biggest single appliance" and "the reason your whole bill is high" aren't always the same thing.

The usual suspects, roughly ranked

A 1.5-ton inverter AC run for several hours a day is typically the largest single load in a Pakistani home, followed by an electric geyser (if used daily), a non-inverter AC of the same size (which draws noticeably more than its inverter equivalent), and a deep freezer or older refrigerator running continuously in the background. Lighting, fans, and electronics individually draw far less, but they add up across a household with several rooms in use simultaneously.

The number that matters more than any single appliance

Because Pakistan's domestic tariff is slab-based and cliff-priced (see our piece on why your bill jumped), the per-unit rate you pay depends on your household's total monthly consumption, not on any appliance in isolation. Adding one more heavy appliance, or running an existing one for longer, can push your total consumption into a higher slab — which raises the effective cost of every unit you use, not just the extra ones from that appliance.

This is why the same air conditioner can feel "cheap" in a low-usage household and "expensive" in a high-usage one — it's not the AC that changed, it's which slab your total consumption landed in.

Actually seeing the breakdown

Guessing at this is unreliable, because wattage varies a lot by appliance type, brand, and whether it's inverter or non-inverter technology. Our appliance electricity calculator lets you add your actual appliances with their hours of use per day, and shows the rupee cost of each — allocated in proportion to your total bill, so the slab effect described above is reflected in the numbers, not hidden from them.

The easiest win

For most households, the single easiest change is running one heavy appliance (usually the AC) for one fewer hour a day. Because of the slab effect, this can save more than the AC's wattage alone would suggest — if it drops your total consumption into a lower slab, every other appliance's effective cost falls too.
