How Appliance Electricity Consumption Is Calculated

Electricity billing worldwide is based on total electrical energy consumed in kilowatt-hours (kWh), commonly called "Units". To calculate the electricity cost of any device:

1. Rated Power (Watts) Appliance wattage rating from manufacturer label (e.g. 1500W).
2. Energy (kWh / Units) (Watts × Operating Hours × Days) ÷ 1,000 = kWh Units.
3. Bill Cost ($ / £ / ₹) Total kWh × Local Retail Tariff Slab + Fixed Charges & Duty.

Calculation Methodology & Formula Regulatory Slabs
Accurate billing computation matching state regulatory schedules

The total electricity bill amount is computed using the regulatory formula:

Net Bill = Energy Charges + Fixed Charges + FAC + Electricity Duty + Meter Rent - Government Subsidy
  • Energy Charges: Calculated by dividing consumption units into sequential progressive tariff tiers and multiplying each block by its specific slab rate (₹/kWh).
  • Fixed Charges: Calculated based on sanctioned load capacity: Load (kW) × Monthly Fixed Rate × Billing Months.
  • Fuel Surcharge (FAC): Variable cost adjustment per kWh consumed: Units × FAC Rate.
  • Electricity Duty: Statutory percentage tax applied to the sum of energy charges, fixed charges, and fuel surcharges.
  • Subsidy: State-specific slab discounts or free electricity units credited against eligible domestic consumption.
