Appliance-Wise Electricity Consumption Calculator
See exactly which appliances are driving your electricity bill, in rupees
Frequently Asked Questions
Figuring out which appliance is actually driving up a Pakistani electricity bill means converting each device's wattage, daily usage hours, and quantity into monthly units (kWh) — since a bill only shows a single total, not a per-appliance breakdown, and the appliances people assume are the biggest culprits often aren't.
Why wattage alone doesn't tell the whole story
An appliance's contribution to a monthly bill depends on three factors multiplied together: its wattage (power draw while running), how many hours per day it actually runs, and how many units of that appliance are in use — a high-wattage appliance used briefly can consume less monthly energy than a lower-wattage one left running for hours, which is exactly why "this appliance has a big number on its label" doesn't reliably predict its actual monthly cost. Air conditioners and other compressor-based appliances (refrigerators, some water pumps) also don't draw their rated wattage continuously — they cycle on and off to maintain temperature — so their effective average wattage over a full day is meaningfully lower than the peak wattage on the nameplate, though this calculator's straightforward wattage × hours model is a reasonable planning estimate rather than a precise cycling simulation.
A worked example
Two appliances with very different power ratings can end up contributing similar amounts to a monthly bill if the lower-wattage one runs for many more hours per day — a small appliance left running continuously in the background can quietly add up to more monthly cost than a high-wattage appliance used only briefly each day, which is the specific insight that per-appliance energy breakdown makes visible.
How this connects to your other electricity planning
Once you know which appliances actually drive your monthly units consumption, that figure feeds directly into the Electricity Bill Calculator to see the actual rupee cost at your DISCO's tariff and slab, and into the Solar System Size Calculator if you're sizing a solar system to offset that specific usage pattern.
Common mistakes
Assuming an appliance's rated (nameplate) wattage represents its actual continuous power draw — rather than accounting for cycling behaviour in compressor-based appliances like ACs and refrigerators — tends to overstate their contribution to a monthly bill; conversely, underestimating how many hours per day a "background" appliance like a router, fridge, or standby device actually runs (often close to 24 hours) tends to understate theirs.
