Electricity Bill Calculator India – How Your Power Bill Is Calculated
Electricity bills in India are calculated using a slab-based tariff system, where the cost per unit of electricity increases as consumption rises. Since tariff rates, duties, and additional charges vary from state to state, estimating your monthly power bill manually can be confusing.
This electricity bill calculator helps residential consumers estimate their monthly electricity charges based on state-wise slab tariffs, applicable electricity duty, and fuel adjustment charges (FAC). The goal is to provide a clear and transparent estimate before your official bill arrives.
How Electricity Bills Are Calculated in India
Most Indian states follow a progressive slab system. Your total electricity consumption is divided into slabs, and each slab is charged at a different rate. Lower slabs usually have lower rates, while higher consumption attracts higher charges.
- Energy Charges: Units consumed multiplied by slab-wise rates
- Fixed Charges: Monthly charges applied by some states
- Electricity Duty: State government tax on energy charges
- Fuel Adjustment Charge (FAC): Variable charge based on fuel costs
Why Electricity Tariffs Differ by State
Electricity tariffs are regulated by State Electricity Regulatory Commissions (SERCs). Differences in power generation sources, subsidy policies, infrastructure costs, and distribution losses cause tariff variations between states.
