How electricity bill is calculated

Most electricity bills are based on units consumed, also called kilowatt-hours. Your provider reads the meter, applies the tariff slab for your category, then adds fixed charges, meter rent, electricity duty, fuel adjustment and any other approved charges. Subsidy, arrears, late fee, security deposit or previous balance can also change the final payable amount.

This calculator divides your monthly units into basic slabs and shows an estimated amount. It is useful for budgeting, comparing appliance usage and understanding why a bill increased, but it should not be used as an official bill.

Main parts of an electricity bill

Energy charges

Amount calculated from consumed units and applicable slab rates.

Fixed charges

Monthly charge based on connection load or category, even if usage is low.

Duty and adjustments

Government duty, fuel adjustment, surcharge, subsidy or arrears can affect the bill.

Popular appliance cost examples

Air conditioner

AC usage can dominate summer bills. Track hours, tonnage and star rating before estimating cost.

Geyser

Water heaters use high wattage. Reducing runtime can lower winter bills.

Refrigerator

Fridges run daily. Old models, poor door seals and high settings increase consumption.

Simple ways to reduce bill

  • Use LED lights and efficient fans.
  • Set AC around 24 to 26 degrees where comfortable.
  • Clean AC filters and service high-load appliances regularly.
  • Switch off standby devices and chargers.
  • Compare old and new monthly units to identify abnormal usage.
