An Indian electricity bill is the energy charge (your units billed through the state slab rates) plus a monthly fixed charge, set by each State Electricity Regulatory Commission (SERC). This tool gives an approximate monthly estimate for 10 states using their current SERC tariff orders (rates as of June 2026). It excludes fuel adjustment (FAC/FPPCA/PPAC), electricity duty and subsidies, and does not model bi-monthly billing (Tamil Nadu, Kerala), the KSEB 250-unit non-telescopic cliff, or Telangana's consumption-category slabs - so your actual DISCOM bill will differ; always verify with your provider.
| States covered | 10: Maharashtra, Delhi, Karnataka, Tamil Nadu, Uttar Pradesh, Gujarat, Rajasthan, Telangana, West Bengal, Kerala |
| What it computes | Monthly slab energy charge + one representative fixed charge |
| Billing model | Telescopic slabs (each band priced at its own rate) |
| Flat-rate state | Karnataka - one rate for all units (KERC abolished domestic slabs) |
| Bi-monthly states (approximated) | Tamil Nadu, Kerala |
| Not in the estimate | Fuel adjustment (FAC/FPPCA/PPAC), electricity duty, state subsidies |
| Fixed-charge basis | Representative ~2 kW connection (real charges are often per kW or per kVA) |

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.
These are simplified residential energy-charge slabs for estimation, taken from each state's current State Electricity Regulatory Commission tariff order. They exclude fixed charges (shown separately in the calculator), fuel adjustment (FAC/FPPCA/PPAC), electricity duty, and state subsidies, and do not model bi-monthly billing (Tamil Nadu, Kerala), the non-telescopic repricing of Kerala bills above 250 units, or consumption-category schedules (Telangana). Always verify with your electricity board.

Rates change with each SERC tariff cycle and exclude fuel adjustment, duty and subsidies. Verify the current tariff with your distribution company before acting on the estimate.
