How Electricity Bill Calculation Works in India

Indian electricity boards use a telescopic tariff system where the per-unit rate increases with higher consumption. Each state has its own tariff structure set by its State Electricity Regulatory Commission (SERC). The bill comprises energy charges, fixed charges, electricity duty, and sometimes fuel adjustment charges.

Understanding Your EB Bill

Your electricity bill has several components: energy charges calculated based on units consumed at slab rates, fixed or demand charges based on your sanctioned load, electricity duty (usually 5-16% depending on the state), and applicable surcharges. Some states also offer subsidized rates for lower consumption tiers.

Frequently Asked Questions

How is electricity bill calculated in India?
Electricity bills in India are calculated using a slab-based system. The per-unit rate increases as consumption rises. The bill includes energy charges (based on units consumed), fixed/demand charges, electricity duty (typically 5-10%), and applicable taxes.
What is 1 unit of electricity?
1 unit of electricity equals 1 kilowatt-hour (kWh). It means using 1000 watts of power for 1 hour. For example, a 100W bulb running for 10 hours consumes 1 unit of electricity.
Why does my electricity bill vary each month?
Your bill varies due to changes in consumption (seasonal use of AC, heaters), slab-based pricing where higher consumption costs more per unit, meter reading cycles, and occasional tariff revisions by state electricity boards.
