Estimate your West Bengal home electricity bill from the official tariff: slabs, fixed charge, surcharges, duty and subsidy.
Quick answer
WBSEDCL bills homes every quarter, slab by slab on the quarter's units: ₹5.04 for the first 102 units, ₹6.33 up to 180, ₹7.12 up to 300, ₹7.52 up to 600, ₹7.69 up to 900 and ₹9.22 above (urban, 2025-26 order). For use up to 900 units a quarter, the state subsidy lowers these rates (₹4.15 to ₹6.89). A fixed charge of ₹30 per kVA a month is added.
