About the Electricity Bill Calculator
The Electricity Bill Calculator is a free, private tool that runs entirely in your browser — your inputs never leave your device, and the answer appears the instant you enter them.
Energy conversions and calculations — watts to kilowatts, units to cost, appliance consumption — are essential for understanding your electricity bill in Pakistan. This Electricity Bill Calculator handles one of those conversions so you can read your energy numbers correctly.
The calculation converts between the standard energy units — watts, kilowatts, kilowatt-hours and units (where 1 unit = 1 kWh) — using the exact relationships between them.
Your electricity bill charges per unit (kWh), while appliances are rated in watts. Converting between the two is the first step to understanding what each appliance costs to run — and to spotting where your bill comes from.
Use the tool with the appliance-cost calculator on this site to build a complete picture of your household's energy use and the savings available from switching to efficient appliances.
For the most accurate outcome from the Electricity Bill Calculator, keep the editable rates and defaults up to date with current figures before reading the result.
