Calculate your monthly electricity bill with state-wise slab rates
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.
Tips to Reduce Your Electricity Bill
- Switch to LED lights and 5-star rated appliances to reduce consumption.
- Use AC at 24-26 degrees with a timer for optimal efficiency.
- Turn off standby devices — they consume phantom power.
- Consider solar panels for long-term savings.
- Monitor your daily consumption to stay within lower slab limits.
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.
