Bihar electricity bills are calculated using slab-wise tariff rates, where different rates apply to different consumption ranges. Fixed charges based on sanctioned load, electricity duty (5%), and fuel adjustment charges are added to determine the final bill amount.
For domestic consumers, rates range from ₹4.00/kWh for 0-100 units to ₹6.90/kWh for above 300 units, varying slightly between NBPDCL and SBPDCL. Commercial rates are around ₹7.50-7.60/kWh.
