About electricity billing in West Bengal
Headquartered at Kolkata, West Bengal electricity tariffs are set by the State Electricity Regulatory Commission through annual tariff orders that specify slab rates, fixed charges, and cost-pass-through mechanisms. Domestic consumers are generally billed on a telescopic basis: only the units within each slab are charged at that slab's rate, so climbing a slab doesn't push your cheaper units to a higher rate.
Apart from energy charges, your monthly bill includes a fixed charge based on sanctioned load (kW), a Fuel & Power Purchase Cost Adjustment (FAC / FPPCA), electricity duty (a percentage-based state levy), meter rent, and any applicable subsidy. Our calculator models each of these components exactly the way your DISCOM does — so the estimate you see here should closely match the figure on your bill.
For the latest tariff orders and notifications, visit your DISCOM's website or the SERC portal. We verify tariff data every quarter against official orders.
