How our Electricity Bill Calculator Works
Calculating your electricity bill can be confusing due to the complex slab structures implemented by various State Electricity Regulatory Commissions. Our tool simplifies this process by continuously updating the backend with the latest tariff rates for 2026.
Understanding the Slab System
In most Indian states, domestic electricity usage is billed on a telescopic slab structure. This means the first 100 units might be billed at ₹3.50/unit, the next 100 at ₹4.50/unit, and so forth. This system is designed to encourage energy conservation by penalizing higher usage with higher rates.
Components of Your Bill
- Energy Charge: The cost of the actual units (kWh) consumed.
- Fixed Charge: A flat monthly fee based on your sanctioned load capacity.
- Fuel Surcharge (FPPCA): Passing the fluctuating cost of fuel to the consumer.
- Electricity Duty/Tax: State government taxes percentage.
