How to Calculate Your Electricity Bill in India

Electricity tariffs in India vary significantly by state and are set by State Electricity Regulatory Commissions (SERCs). Most states use a slab-based tariff system where the per-unit rate increases as consumption increases - the first 100 units may cost Rs.3 per unit while consumption above 500 units may cost Rs.8-10 per unit.

Your electricity bill includes the energy charge (based on units consumed), fixed charges (a monthly base charge regardless of consumption), fuel adjustment charges, electricity duty (a state tax), and sometimes wheeling charges for grid use.
